1.7b1: Problem reading GIS files

[Benjamin Mewes]

Hi all,

it is me again. Sorry for bothering you again. Currently all(!) of my raster based examples don't work anymore. Suddenly it shows the following error:

2 occurences in 2 agents at cycle 0: The format of cantho_1999_v6.asc is not correct. Error: Inconsistency between the data and the CRS: The CRS GEOGCS["WGS 84",
  DATUM["World Geodetic System 1984",
    SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]],
    AUTHORITY["EPSG","6326"]],
  PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
  UNIT["degree", 0.017453292519943295],
  AXIS["Geodetic longitude", EAST],
  AXIS["Geodetic latitude", NORTH],
  AUTHORITY["EPSG","4326"]] corresponds to a not projected one, whereas the data seem to be already projected.
for file C:..\GitHub\gama\msi.gama.models\models\Toy Models\Urban Growth\includes\cantho_1999_v6.asc
when applying the envelope operator on msi.gama.util.file.GamaGridFile@3e022b51
in initializing attribute shape
in agents Simulation #0 of model raster3, raster0

It does likewise with the Flood Model from the Library but the ShapeFiles (e.g. from the traffic model) work correctly.

Any ideas what might be the problem?

All the best

Hi,

i think the prj file corresponding to your asc file is not the good one. I mean, your data seem to be already projected (it is the case on my computer for the cantho_1999_v6.asc file), whereas your prj file says that is not the case (crs : WGS84). You can try to delete the crs files that correspond to your asc files.

Cheers,

Patrick

Hmm, in the example folders there is now CRS file. Only a PRJ. I tried to delete it, without any success. The file is gone, but the raster doesn't appears.

The error is still the same. I will try to make a clean build of 1.7...

[Benjamin Mewes]

I tried it once more without success. All ASC files are rejected with the same error code. The used to work before.  Does GAMA somehow manipulate any of the PRJ files?

I can show all data in QGIS without problems.

Hi,

On my computer (with the last version of GAMA git), it is working quite well. Can you try to create a new workspace of to revert your preference to default?

Cheers,

Patrick

[Benjamin Mewes]

Well, I got a new workspace and all combinations of preferences as well without success :(

Do I need to install spatialite?

[Patrick Taillandier]

I have just tested again with my windows computer (Win 10 64 bits), with GAMA 1.7 b1 (downloaded 5 minutes ago) and with a new workspace and it works well :( .

Which OS are you using? Can you try to download again GAMA 1.7b1 (https://github.com/gama-platform/gama/wiki/Download%20GAMA)?

[Benjamin Mewes]

Hi,

I am on Win 7 Professional on a 64Bit System. Strangely a fresh install of GAMA 1.7 b1 (from installer) with a fresh workspace isn't able to run *any* models anymore. My Github version of 1.7b1 in Eclipse is working (apart from not being able to read ASC files anymore).

[Benjamin Mewes]

I got it working again !

Thanks to you Patrick somehow an old version of my workspace was in the same directory (although never loaded). After deleting it, it worked out!
