* <code>VBoxManage modifyvm ubuntu --memory 8000</code>
* <code>VBoxManage startvm ubuntu</code>

other:
* options of ip-addressing/web access: NAT (Network Address Translation) or Bridge (see also this [http://catlingmindswipe.blogspot.com/2012/06/how-to-virtualbox-networking-part-two.html blog entry])
* downloading .iso archives/vm from OSGeo (use commands ''curl'' or ''wget -c''), e.g.:
<pre>
wget -c "http://downloads.sourceforge.net/project/osgeo-live/7.0/osgeo-live-7.0.iso?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fosgeo-live%2Ffiles%2F%2F7.0%2Fosgeo-live-7.0.iso%2Fdownload&ts=1384444616&use_mirror=ufpr"

a VM contains 3 files: .img + .vbox (an editable xml) + .vbox-prev

== OpenTripPlanner ==
* start with "sh start-server.sh"; use "&" at the end to keep the process running
* make sure that winstone.jar is executable, with chmod 755
* define in the start-server.sh file also where the webapps folder is located (physical location), so winstone knows that
* define in the WEB-INF/classes/data-sources.xml file where the graph is stored (physical location) - the files is within /otp/webapps/opentripplanner-api-webapp.war (or: the deflated war folder)
* kill winstone server (or OTP) process: use <pre>ps aux | grep winstone</pre> to find the associated PID, and use <code>kill pid</code>

== unix commands ==
http://www.computerhope.com/issues/ch000623.htm

connect to server:
*ssh stefan@136.159.xxx.xxx

*pid
* (sudo) kill pid, e.g. kill 320
*top or: htop
*process
* "sudo shutdown now -h" or "sudo reboot"
* seeing system info: <code>cat /etc/*-release</code> + htop (needs to be installed first)
* '''grep''': search for files in the folder ''/var/.../static/'' that contain the string ''nav-pills'' with: <code>grep -r -i "nav-pills" /var/www/geonode/static/</code>
* find files/folders by name: <code>find / -name game</code>
and:
*commands to display/figure out processes: http://www.howtogeek.com/107217/

*use of ''grep'': http://www.cyberciti.biz/faq/howto-use-grep-command-in-linux-unix/
*used ports: <code>netstat -a</code>
*mac addresses: <code>ifconfig -a</code>

== Installing lightweight XFCE Desktop GUI on Ubuntu Server ==
* use <code>sudo apt-get install xubuntu-desktop</code> to install XFCE client (see [http://help.ubuntu.com/community/ServerGUI here]).
* this will also install xauth, which allows remote window clients
* disable start of GUI-based login on system startup with Grub (taken from [http://askubuntu.com/questions/174312/how-can-i-set-my-ubuntu-12-04-lts-to-boot-to-console-without-gui here]):
** Change (edit) in /etc/default/grub file: <code>GRUB_CMDLINE_LINUX_DEFAULT="text"</code>
** then do <code>sudo update-grub</code>
* start the desktop GUI session using <code>startx</code>
* end the desktop GUI session using "logout" button

== Enabling Remote Desktop for Windows ==
got the info from [http://www.ubuntututorials.com/remote-desktop-ubuntu-12-04-windows-7/ here]
* install XRDP: <code>sudo apt-get install xrdp</code>
* connect via Windows Remote Desktop using the IP etc.
* if not needed, switch off the remote desktop server using: <code>sudo service xrdp stop</code>

== other stuff ==
* gdalinfo cgydem_fromgrid.tif
* if computer crashs: boot from a LiveDVD and the run <code>fsck</code> (see http://www.thegeekstuff.com/2012/08/fsck-command-examples/)
* '''compress''':
** files by using: <code>zip newzipfile.zip fileToZip.obj</code>
** whole folders by using: <code>tar -cvzf tarfilename.tgz /folder/to/compress</code>
* '''uncompress''':
** zip files, using: <code>unzip filename.zip</code>,
** bz2 files with: <code>bunzip2 filename.bz2</code>
** tar files: <code>tar -C / -xvzf tarfilename.tgz</code> . ''Attention !!!'' This will restore the data exactly in the same place on the computer, and overwrite existing folders and files.

Setting up osgeo vm

== Setup of an OSGeo Virtual Machine with VirtualBox ==

Setting up a [http://live.osgeo.org/es/ OSGeo VirtualBox-VM] on Lautaro with SuseLinux - but using command line (because creating the VM via the graphical interface ''vboxgtk'' did not work properly).
The general documentation was taken from here: http://stdioe.blogspot.com/2012/01/creating-virtual-machine-with.html

'''Steps''':
# install virtualbox on server/computer (done by Daniel, needs admin rights of course)
# download the iso with the OS, for ubuntu (= not OSGeo live): <pre>curl -L -O http://releases.ubuntu.com/12.04.3/ubuntu-12.04.3-server-i386.iso > ubuntu12043server.iso</pre>
# create a VM based on Ubuntu: <pre>VBoxManage createvm --name osgeo --ostype Ubuntu --register</pre>
# check it is there: <pre>VBoxManage showvminfo osgeo</pre>
# set the memory/ram: <pre>VBoxManage modifyvm osgeo --memory 8192</pre> (which is 8GB)
# check the memory/ram: <pre>VBoxManage showvminfo osgeo | grep "Memory size"</pre>
# set the number of cpu's to use (here 4): <pre>VBoxManage modifyvm osgeo --cpus 4</pre>
# set the network connection/routing nat: like behind a firewall, access from host, e.g. PostgisVM - vs. - bridge: want to be visible from outside, using my own IP, e.g. GeoNodeVM <pre>VBoxManage modifyvm osgeo --nic1 nat</pre> Here we use 'nat'-ing instead of a bridge. For a bridge we have to use unstead: first this command: <code>VBoxManage modifyvm osgeo --bridgeadapter1 eth0</code> and then, this command: <code>VBoxManage modifyvm osgeo --nic1 bridged</code>.
# create a harddisk of 100GB size:<pre>VBoxManage createhd --filename osgeo.vdi --size 100000</pre>
# define the VM's disk controller:<pre>VBoxManage storagectl osgeo --name "SATA Controller" --add sata --controller IntelAhci</pre>
# mount the disk:<pre>VBoxManage storageattach "osgeo" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium osgeo.vdi</pre>
# check if everything is there:<pre>VBoxManage showvminfo osgeo</pre>
# add DVD device:<pre>VBoxManage storagectl osgeo --name "IDE Controller" --add ide --controller PIIX4</pre>
# load the DVD device with the Ubuntu VM/osgeo ''iso'' file (check if the iso has proper rights, i.e. maybe do a chmod 775):<pre>VBoxManage storageattach osgeo --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium yyy/osgeolive7.iso </pre>
# starting VM <pre>VBoxHeadless -s osgeo -n -m 7777 & </pre> The -s is for start, 7777 defines the port for conecting with VNC, and the & is for keeping the VM running when I disconnect from the server. Headless actually means, that we have no monitor...
# don't forget to install VNC Viewer (e.g. [http://www.realvnc.com/ RealVNC]), and then connect via the defined port - to "146.155.xx.xxx:7777"
# ... do a real install of the osgeo VM, etc.
# install ssh server <pre>sudo apt-get install openssh-server</pre>
# how to do a mapping for ssh (& ftp), so that the guest VM can be reached from the host machine is described here: http://blogs.oracle.com/rmanus/entry/virtualbox_how_to_ftp_from In particular one has to do the following: <pre>VBoxManage modifyvm osgeo --natpf1 "ssh,tcp,,2222,,22"</pre>These entries are then added to osgeo.vbox xml file. For ftp the port would be 21 instead of 22. To enable Apache, do the same but use: config folder "apache", HostPort "8888", GuestPort "80", Protocol "TCP", e.g. (as one line): <pre> VBoxManage modifyvm osgeo --natpf1 "apache,tcp,,8888,,80"</pre> and for Tomcat: <pre> VBoxManage modifyvm osgeo --natpf1 "tomcat,tcp,,8889,,8080"</pre>
#* Note, if a "Error: failed to start machine. Error message: Configuration error: Failed to get the "MAC" value (VERR_CFGM_VALUE_NOT_FOUND)" appears, then it may be necessary to change the network adapter to PCnet-FAST III (Am79C973), according to this [http://room2blog.wordpress.com/2010/10/04/setting-up-post-forwarding-for-virtual-box-on-ubuntu-10-04/ Blog entry]
# check here on how to detach the medium use: <pre>VBoxManage storageattach osgeo --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium none</pre>
# shutting down the vm per vboxmanage : <pre>VBoxManage controlvm <uuid>|<name> pause|resume|reset|poweroff|savestate|acpipowerbutton|acpisleepbutton</pre>
# tomcat 6 can be found in /usr/share/tomcat6/bin. However, the start/stop command is simply: <pre>sudo service tomcat6 start</pre> Check out: [http://hendrelouw73.wordpress.com/2012/06/06/how-to-install-apache-tomcat-6-0-35-on-ubuntu-12-04-linux/ Blog: How to instal Tomcat 6 on Ubuntu 12.04]. Also, don't forget to create users for the manager interface (see [http://www.mkyong.com/tomcat/tomcat-default-administrator-password/ this Blog post]). Finally, the right amount of memory can be assigned in the file ''/etc/tomcat6/tomcat6.conf''. However, I did not had this file. So I created a new file setenv.sh in ''/usr/share/tomcat6/bin'' via <pre>sudo touch setenv.sh</pre> and then edited it adding the following lines: <pre>#!/bin/sh 
JAVA_OPTS="-Xms512m -Xmx4g -XX:MaxPermSize=270m -server -Djava.awt.headless=true -Djava.util.prefs.systemRoot=$CATALINA_HOME/content/thredds/javaUtilPrefs" 
export JAVA_OPTS</pre>Then I stopped and re-started tomcat. The above method also worked with Tomcat7.
# displaying catalina output: <pre>cd /var/lib/tomcat6</pre><pre>tail -f logs/catalina.out</pre>
# activate remote desktop for VBox:<pre>VBoxManage modifyvm osgeo --vrde on</pre><pre>VBoxManage modifyvm osgeo --vrdemulticon on</pre>and define the port number<pre>VBoxManage modifyvm osgeo --vrdeport XXXX</pre>

== Other Notes ==

=== '''Install & updates''' ===
When Installing Ubuntu server, I got actually problems with the update sever, and had to switch to main. For that I used:
<pre>sudo nano /etc/apt/sources.list</pre>
Then locate <code>http://cl.archive.ubuntu.com/ubuntu</code> and replace it with <code>http://archive.ubuntu.com/ubuntu</code>. 
Afterwards, installing htop with <code>sudo apt-get install htop</code> worked as well, why it did not work before.

=== '''Installing a GUI''' ===
Installing a (optional) GUI for Ubuntu is described here: http://www.maketecheasier.com/use-a-gui-on-a-ubuntu-server/ 
See also my notes on the [[accessing server infra]] page.

=== '''Changing Vbox mac address''' ===
use <pre>VBoxManage modifyvm osgeo --macaddress1 08002783b21e</pre>

After that my eth0 disappeared and stayed without internet connection! I got it back by deleting: ''/etc/udev/rules.d/70-persistent-net.rules'' and rebooting. This tip came from [https://forums.virtualbox.org/viewtopic.php?f=7&t=43090 here].

Next I had to set the IP manually, using command line. How to do this via command line is described [http://www.cyberciti.biz/tips/howto-ubuntu-linux-convert-dhcp-network-configuration-to-static-ip-configuration.html here]

=== '''Changing the max upload size of wars for Tomcat 7''' ===

use <pre>/usr/share/tomcat7-admin/manager/WEB-INF$ sudo nano web.xml</pre>
and change the max file setting. (Note, the ''tomcat7-admin'' package needs to be installed first).

More info on installing tomcat: http://help.ubuntu.com/13.04/serverguide/tomcat.html

=== '''Copying a VDI (Harddisk) file to attach it to another VM''' ===

If a vdi is copied and/or renamed, and then should be attached to a different VM one needs to assign a new UUID, otherwise the following message appears:
<pre>VBoxManage: error: Cannot register the hard disk '/home/sstein/backuppostgis.vdi' {60886f08-fedb-49dc-aec0-a1a9ae54a43b} because a hard disk '/home/sstein/backupgeonode.vdi' with UUID {60886f08-fedb-49dc-aec0-a1a9ae54a43b} already exists [...]</pre>

In my case I wanted to create a new VM (backuppostgis) without installing ubuntu again.

To assign a new UUID use: <code>VBoxManage internalcommands sethduuid backuppostgis.vdi</code>

Note, that re-using a harddisk/vdi with another/new VM means, that the network connection of the VM will not work, as we have a new network card. To solve this see above (comment out the now two network card adapters in ''/etc/udev/rules.d/70-persistent-net.rules'' and do a reboot).

The computers name can be change by editing ''/etc/hostname''. Still, on "sudo" may appear: "unable to resolve host xxx". This indicates that the hostname should be changed as well in ''/etc/hosts''.

== Fast setup of VM from existing VM disk tarball ==
I have a tarball of a VM disk with a fresh Ubuntu Server install (the tar file is called "vmBackupGeoNodeDisk.tgz"). This can serve to setup fairly fast a new Ubuntu based VM.
* untar the disk tarball with Ubuntu installed <code>tar -C /home/sstein/untar -xvzf /home/sstein/vmbackup/vmBackupGeoNodeDisk.tgz</code>
* copy and rename VM disk file to folder with other disk files: <code>mv untar/home/sstein/backupgeonode.vdi /home/sstein/wypwps.vdi</code>
* assign a new serial ID to the disk so it can be used by the new VM: <code>VBoxManage internalcommands sethduuid wypwps.vdi </code>
* create new VM:
<pre>
VBoxManage createvm --name wyp --ostype Ubuntu --register
VBoxManage modifyvm wyp --memory 4096
VBoxManage modifyvm wyp --cpus 4
VBoxManage modifyvm wyp --nic1 nat
VBoxManage storagectl wyp --name "SATA Controller" --add sata --controller IntelAhci
VBoxManage storageattach "wyp" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium wypwps.vdi
VBoxManage modifyvm wyp --natpf1 "ssh,tcp,,17022,,22"
VBoxManage modifyvm wyp --natpf1 "apache,tcp,,17080,,80"
VBoxManage modifyvm wyp --natpf1 "tomcat7,tcp,,17088,,8080"
</pre>
* start the VM: <code>VBoxHeadless -s wyp -n -m 7773 &</code>
* login with usual name (ss-) and password (2*-*s)
* note, the VM has a bit weird keyboard setting. So I haven't figured where / etc is - which makes navigation difficult. So, connecting via ssh, after solving the problem below, is best.
* fix network connection problem by commenting out the two network card adapters in ''/etc/udev/rules.d/70-persistent-net.rules'' and do a reboots in

== Further VMs that I am running ==
* VBoxHeadless -s geonode -n -m 7779 & => bridged (with own IP)
* VBoxHeadless -s postgis -n -m 7778 & => nat (9022, 9080)
* VBoxHeadless -s backupgeonode -n -m 7776 & => nat (14022, 14080) : powered down
* VBoxHeadless -s backuppostgis -n -m 7775 & => nat (15022, 15080) : powered down
* VBoxHeadless -s tilestream -n -m 7774 & => nat (16022, 16080) : should be running - with TileStream PID 4672 on port 16088
* VBoxHeadless -s wyp -n -m 7773 & => nat (17022, 17080) : should be running
* osgeo VM should be powered down, as it was only for testing
* check running VMs using: <code>VBoxManage list runningvms</code>
* existing VMs using: <code>VBoxManage list vms</code>
* stopping an unresponsive VM: <code>VBoxManage controlvm VMNAME poweroff</code>

<pre>VBoxManage: error: Cannot register the hard disk '/home/sstein/backuppostgis.vdi' {60886f08-fedb-49dc-aec0-a1a9ae54a43b} because a hard disk '/home/sstein/backupgeonode.vdi' with UUID {60886f08-fedb-49dc-aec0-a1a9ae54a43b} already exists [...]</pre>

In my case I wanted to create a new VM (backuppostgis) without installing ubuntu again.

To assign a new UUID use: <code>VBoxManage internalcommands sethduuid backuppostgis.vdi</code>

Note, that re-using a harddisk/vdi with another/new VM means, that the network connection of the VM will not work, as we have a new network card. To solve this see above (comment out the now two network card adapters in ''/etc/udev/rules.d/70-persistent-net.rules'' and do a reboot).

The computers name can be change by editing ''/etc/hostname''. Still, on "sudo" may appear: "unable to resolve host xxx". This indicates that the hostname should be changed as well in ''/etc/hosts''.

== Fast setup of VM from existing VM disk tarball ==
I have a tarball of a VM disk with a fresh Ubuntu Server install (the tar file is called "vmBackupGeoNodeDisk.tgz"). This can serve to setup fairly fast a new Ubuntu based VM.
* untar the disk tarball with Ubuntu installed <code>tar -C /home/sstein/untar -xvzf /home/sstein/vmbackup/vmBackupGeoNodeDisk.tgz</code>
* copy and rename VM disk file to folder with other disk files: <code>mv untar/home/sstein/backupgeonode.vdi /home/sstein/wypwps.vdi</code>
* assign a new serial ID to the disk so it can be used by the new VM: <code>VBoxManage internalcommands sethduuid wypwps.vdi </code>
* create new VM:
<pre>
VBoxManage createvm --name wyp --ostype Ubuntu --register
VBoxManage modifyvm wyp --memory 4096
VBoxManage modifyvm wyp --cpus 4
VBoxManage modifyvm wyp --nic1 nat
VBoxManage storagectl wyp --name "SATA Controller" --add sata --controller IntelAhci
VBoxManage storageattach "wyp" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium wypwps.vdi
VBoxManage modifyvm wyp --natpf1 "ssh,tcp,,17022,,22"
VBoxManage modifyvm wyp --natpf1 "apache,tcp,,17080,,80"
VBoxManage modifyvm wyp --natpf1 "tomcat7,tcp,,17088,,8080"
</pre>
* start the VM: <code>VBoxHeadless -s wyp -n -m 7773 &</code>
* login with usual name (ss-) and password (2*-*s)
* note, the VM has a bit weird keyboard setting. So I haven't figured where / etc is - which makes navigation difficult. So, connecting via ssh, after solving the problem below, is best.
* fix network connection problem by commenting out the two network card adapters in ''/etc/udev/rules.d/70-persistent-net.rules'' and do a reboots in

== Further VMs that I am running ==
* VBoxHeadless -s geonode -n -m 7779 & => bridged (with own IP)
* VBoxHeadless -s postgis -n -m 7778 & => nat (9022, 9080)
* VBoxHeadless -s backupgeonode -n -m 7776 & => nat (14022, 14080) : powered down
* VBoxHeadless -s backuppostgis -n -m 7775 & => nat (15022, 15080) : powered down
* VBoxHeadless -s tilestream -n -m 7774 & => nat (16022, 16080) : should be running - with TileStream PID 4672 on port 16088
* VBoxHeadless -s wyp -n -m 7773 & => nat (17022, 17080) : should be running - with TileStream PID 4672 on port 16088
* osgeo VM should be powered down, as it was only for testing
* check running VMs using: <code>VBoxManage list runningvms</code>
* existing VMs using: <code>VBoxManage list vms</code>

Steps to Install the WalkYourPlace tool for Santiago

== '''General prep steps''' ==
# create new Ubuntu 12.04 VM with LA(M)PS ( 7773, lautaro:17022)
#* when using an existing VM image :
#** fix network issue (remove old card settings in ''/etc/udev/rules.d/70-persistent-net.rules'' and reboot)
#** set new machine name (in ''/etc/hostname'')
#** check if apache2 starts with an error message or not (for a fix see [[Setting up geonode]] > Basic Install for GeoNode v. 2.0)
# install tomcat 7 (or jetty)
# install GeoServer + WPS plugin
# install Php cURL (http://php.net/curl)
#* geoserver should run on port 8080, otherwise modify "call_wps.php".
# install OpenTripPlanner (running on GeoNode VM (146.155.17.54:8080) - and compile graph with
#* Santiago OSM data
#* Santiago GTFS data
#* => test if it works
# install PostgreSQL + PostGIS (17032 : db: ''wypdb'')
#* install PostgreSQL

== '''Install for Calgary''' ==
# Install DBs
#* install crime DB (for the crimes, we considered 12 types of crime as listed in http://crimemap.calgarypolice.ca/ : weighing is in ''AggregationService.py'')
#* install GTFS DB
# get Browser client code "WPSClient"
#* modify browser client end-point IP (WPS, etc.) in file ''call_wps.php'' to http://146.155.17.113:17088/geoserver/
#* put client app in Apache's ''/var/www/'' (e.g.: /var/www/wypwps)
#* note: the map tiles, as defined in ''js/main.js'', will still come from http://136.159.122.90/PHPTileServer/CalgaryGrey/{z}/{x}/{y}.png However, in case the TileServer is down its possible to add OSM map with <pre>var osmmap = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {attribution: 'Map data © <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'});</pre> add this layer to the layer selection and set as default layer (PS: also remove setting of the map bounds, see <code>map.setMaxBounds(bounds);</code>)
# get back-end code
#* GeoServer WPS servers *.jar files = one for each model or a single file for all (made recently by EP) => install in GeoServers ''*/WEB-INF/lib folder'' (which may be located under /var/lib/tomcat7/webapps/geoserver/...) => restart GeoServer
#** check if it works with http://146.155.17.113:17088/geoserver/ows?service=wps&version=1.0.0&request=GetCapabilities
#* GeoProcessing Engine (access model code in Python) => put in any folder
#* modify the postgres DB access in ''postgis.conf''
#* next I would also need modify the OpenTripPlaner URL in in the jar of the WPS module = model. If not modified the Walkshed request is send to the GISciencegroup OTP server.
#* install "[http://initd.org/psycopg/install/ psycopg2]" python modul which allows access to PostgrSQL: <code>pip install psycopg2</code> (for that, [http://groups.google.com/forum/#!topic/django-users/IfL_uhqFyME install before] "python-dev" and "libpq-dev")
#* start each model with "run.py"
#** it may be necessary to change run.py because I get an error at the moment as I am not having gnome-terminal available via command line. Hence, I am starting the scripts using commandline <code>python xxx.py &</code>. Attention, the CrimeService.py and AggregationService.py script needs to be started from within its folder, otherwise config.py will not find the postgis.conf file (working directory issue).
#**# the Management Service (for pedestrian network) will listen on http://0.0.0.0:8363/
#**# the Crime Service will listen on http://0.0.0.0:8366/
#**# the Aggregation Service will listen on http://0.0.0.0:8364/
#**# the POI Service will listen on http://0.0.0.0:8365/
#** My running processes I can see then with <code>ps -u ssteinig</code>
#** ToDo: check if it is possible to use "subprocess.Popen" or "Multiprocess" (see examples on stackoverflow and [http://stackoverflow.com/questions/3781851/run-a-python-script-from-another-python-script-passing-in-args here])
#* Note, not sure, but in ManagementService.py the GeoServer URL is defined with http://127.0.0.1:8080/geoserver - maybe this needs to be changed (for use in a VM???)

Steps to Install the WalkYourPlace tool for Santiago

'''General prep steps'''
# create new Ubuntu 12.04 VM with LA(M)PS ( 7773, lautaro:17022)
# install tomcat 7 (or jetty)
# install GeoServer + WPS plugin
# install Php cURL (http://php.net/curl)
#* geoserver should run on port 8080, otherwise modify "call_wps.php".
# install OpenTripPlanner (running on GeoNode VM (146.155.17.54:8080) - and compile graph with
#* Santiago OSM data
#* Santiago GTFS data
#* => test if it works
# install PostgreSQL + PostGIS (17032 : db: ''wypdb'')
#* install PostgreSQL

'''Install for Calgary'''
# Install DBs
#* install crime DB (for the crimes, we considered 12 types of crime as listed in http://crimemap.calgarypolice.ca/ : weighing is in ''AggregationService.py'')
#* install GTFS DB
# get Browser client code "WPSClient"
#* modify browser client end point (WPS, etc.) in file ''call_wps.php'' to http://146.155.17.113:17088/geoserver/
#* put in apache's ''/var/www/'' (i.e. /var/www/wypwps)
#* note: the map tiles, as defined in ''js/main.js'', will still come from http://136.159.122.90/PHPTileServer/CalgaryGrey/{z}/{x}/{y}.png However, in case the TileServer is down its possible to add OSM map with <code>var osmmap = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {attribution: 'Map data © <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'});</code> plus adding this to the layer selection plus as default layer (PS: also remove setting of the map bounds, see <code>map.setMaxBounds(bounds);</code>)
# get backend code
#* GeoServer WPS servers *.jar files = on for each model => install in GeoServers ''*/WEB-INF/lib folder'' => restart GeoServer
#** check if it works with http://146.155.17.113:8080/geoserver/ows?service=wps&version=1.0.0&request=GetCapabilities
#* GeoProcessing Engine (access model code in Python) => put in any folder
#* modify the postgres DB access in ''postgis.conf''
#* start each model with "run.py"
# test ic Calgary works

'''Modify code for Santiago'''
# install PyCharm to modify client code and backend code
#* GeoServer WPS location (IP/address)
#* Postgres location and access: ''postgis.conf''
#* Tileserver location/code in client
#* remove crime calculation in ''ManagementService.py''
# deploy code:
#* client side code => install on var/www/ of apache server
#* if there are no changes: GeoProcessing Engine(s) => put in whatever folder and run "run.py"
#* GeoServer WPS servers *.jar files => put in GeoServers ''*/WEB-INF/lib'' folder (requires restart of GeoServer)
# Test
