Problems I discovered when Uploading Data to GeoNode

Spanish characters

Problem: Sometimes, after upload names of attributes or attribute values are not correctly represented, i.e. Categor�A

Solution: This is an encoding problem. Before hitting the upload button in geonode, select the file encoding. In most cases it encoding is Latin 1.

Transformation error

Problem: The shapefile upload fails with an error. In particular I get:

java.lang.RuntimeException: java.io.IOException: transform error

and also (looking /usr/share/geoserver/data/logs/geoserver.log) I got:

Caused by: java.io.IOException: transform error

       at org.geotools.referencing.operation.projection.TransverseMercator.inverseTransformNormalized(TransverseMercator.java:217)

Reason: In some cases, there may be points/geometries with coordinates at 0/0 that cannot be transformed.

Solution: The problem is that there seems to be a misfit with the projection. Remember:

• Chile's Easter Island is far off, so UTM 19S is perhaps not so good working as it is not in zone 19

To solve this issue I re-saved the shapefile as WGS84 (epsg 4326) in geographic coordinates (and also I used UTF-8 character encoding, just to make sure). This new shapefile I was able to load in GeoNode 2.0
