Happy New Year!

I am trying to convert a Transverse_Mercator Projection shapefile to a GML version before i can import it into the DHIS2 and i have religiously followed the Manual ( http://dhis2.org/doc/snapshot/en/user/html/ch16s02.html ) and the following is what i get…

Hi Martin,

Try

ogr2ogr -s_srs EPSG:32626 ..

You need to provide the EPSG code for the projection system.

Hi,

Are you trying to convert shape file coordinates to GML file is it ? have you simplified the shape file before converting ? If possible can you post what command you are using to convert gml file.

Hey Jason,

A quick one, its supposed to be ogr2ogr -s_srs EPSG:32636 … and not EPSG:32626

Thought i should re-share this…

Hi Martin,

This is the actual command :

ogr2ogr -s_srs EPSG:27700 -t_srs EPSG:4326 -f GML filename.gml filename.shp

Here please change your EPSG values…

Hope this will work.

Hi Martin,
Was not 100% sure about the projection, but the important point is that you must use the correct EPSG reference number for the projection system for the source data. Of course, currently only the EPSG:4326 (lat/long) projection is supported by DHIS2, so for the time being, this will always be the target projection system.

Jason

And you should definitely not use an arbitrary projection system. Suneel, the one which you mention is the British National Grid (http://spatialreference.org/ref/epsg/27700/) and would certainly not be appropriate for Martin’s projection system. So importantly, you should be very sure which projection system your source data is in and what it’s EPSG code is before you try and convert the data to something DHIS2 will like.

Jason
