I tried to upload the "States" shapefie, which was exported from Geomdeia USSampleData Warehouse, Using Geomedia professional 2016.
While processing, I got an error mesage without much decription. Just "ERROR".
Same error is raised for Any other Shp which is exported by Geomedia, no matter which EPSG. I get an error also if I try to upload a Geojson which was converted from those SHPs.
Other SHPs which I got from other sources worked just fine, also Geojson which were converted from those other.
What can be the reason? How should I prepare Vector data from Geomedia to be succesfully uploaded to Mapp Chest\Studio.
The SHP is attached

have you tried to convert the source data to EPSG 4326? When uploading shp file to M.App Chest, please remember to upload all necessary files:

Yes I tried also with EPSG:4326 and I uploaded *.shp ; *.dbf ; and *.shx
Attach is a sahpefile in EPSG:4326 with a single polygon whiich cannot be processed.

The Shapefile data is still in Israeli projection, if I check the PRJ file it contains:
What you need to do in GeoMedia is to change the GWS coordinate system before exporting the data to EPSG:4326
Then use Manage Data > Export to... > Shapefile and check again if the exported PRJ file contains the expected CRS.
After that I was able to load the data in M.App Chest and view the results.

Thank you Jan,
I see, I guess I missed something in the transformation workflow. Now it is clear.
Anyway, which SRS's are valid for Raster and for Vector datasets?

You can upload into the M.App Chest (and then use it in Smart M.App) shape files in any coordinate system but the following conditions must be met:
If your shape files are in EPSG:4326 you need to upload three files:
If your shape files are in other SRS than EPSG:4326 you must also upload *.prj file with proper SRS definition.
It should be noted that PRJ file must contain the optional AUTHORITY entry, which describes any standard designation for projection.
For example the PRJ file which is generated by GeoMedia during data export to shape files is deprived from AUTHORITY entry, therefore you need to add it manually at the end of file.

Here is the sample PRJ file for EPSG:3857 SRS with optional AUTHORITY entry:
Please note that normally a PRJ file contains all the text on a single line with no extra spaces. Here it is reformatted for better clarity.
