Hi everyone,

Sorry for reviving an old thread. I was trying to look back through the list as well as online for a little help but couldn’t come up with anything.

I am not sure if this is the right place to ask, but I was looking for a simplified method to perform this step on a set of polygons as outlined in the user guide:
Coordinates: The number of significant decimal digits (e.g. 23.02937874993774) should be shortened to fewer digits (e.g. 23.03). Although this will result in some inaccuracies on the map, given the usual scale at which maps in DHIS2 are produced (> 1:50,000), the loss of precision should not be noticeable. Normally, no more than four significant digits after the decimal point should be necessary

I went ahead and tried an import preview after following the rest of the steps in the guide and things seemed OK as no new org units were being added, but as speed is a real issue here I wanted to shorten the significant digits down to 2 decimal places as suggested before actually importing. Is there any additional resources I could have a look at or is this perhaps more complicated than I am thinking?

Thanks,
Nick

Hi.

Jason took a look on my files and it appears actually that some .dbf files were corrupted. This could happen as he says when opening a .dbf file with Excel than saving it again with this software.

I've been able to correctly run ogr2ogr command with new .dbf files taken from the source and generate the appropriate .gml files. It might be interesting for this task to get tools for checking integrity of shapefiles, any idea ?

Thank you for your help.

Best regards,
Kader

You have to run the FWTools shell, not your ordinary command window.

Once you have opened that, just go to c:\Simplification:

> cd
> cd Simplification

Rremove the previously generated file:

>rm Communes.gml

Now try again:

> ogr2ogr -f GML Communes.gml Communes.shp

Yes Knut,

They are the same. Attached screenshot of directory and QGIS attribute table.

Is it because I'm running the FWTool ogr2ogr from the FWTool directory whereas the shapefiles are in a different dir (see 3rd screenshot) ?

Are you sure the name of the .shp and .dbf files are exactly the same?

Hello,

I am following the 'Setting up GIS' chapter in order to add our country boundaries to DHIS2, but I am not getting in the converted GML files the names of the feature members as described in the manual.

These info being stored in the .dbf files of the shapefiles structure, isn't there another step in order to merge them with the .shp files in order to have them described into the .gml files when using the conversion tool ?

Below an excerpt of one gml file:

 <gml:featureMember>
    <ogr:communes fid="0">
      <ogr:geometryProperty><gml:Polygon srsName="EPSG:4326"><gml:outerBoundaryIs><gml:LinearRing><gml:coordinates>44.520928,-12.21365 44.516667,-12.213444 44.515377,-12.217299 44.508177,-12.219482 44.48914,-12.219355 44.483688,-12.215721 44.474738,-12.211509 44.474765,-12.207788 44.486503,-12.198935 44.488153,-12.194262 44.492306,-12.191121 44.492686,-12.188164 44.490472,-12.187333 44.484528,-12.18125 44.47715,-12.175736 44.473761,-12.172392 44.469769,-12.165611 44.466832,-12.161886 44.497145,-12.154971 44.500402,-12.153843 44.503083,-12.159002 44.503082,-12.162418 44.507053,-12.171983 44.511,-12.176615 44.513624,-12.178458 44.515082,-12.184026 44.517226,-12.187109 44.519828,-12.192961 44.517851,-12.194513 44.520828,-12.197976 44.520943,-12.201551 44.519115,-12.204698 44.519313,-12.209046 44.520928,-12.21365</gml:coordinates></gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></ogr:geometryProperty>
    </ogr:communes>
  </gml:featureMember>

which shows no property holding the name of the feature members.

What could be missing ?

Thanking you in advance.

Best regards,
Kader
