extension exception: 1944553 while applying raster netlogo gis

Question

I am trying to load an ascii into Netlogo with apply-raster from the GIS extension. While I did this many times before (although not with this specific ascii), netlogo now throws the following error:

extension exception: 1944553
error while observer running GIS:APPLY-RASTER

I am not sure why this is happening. The ascii has a projection file with it (WKT), which should work fine:

GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

The ascii itself has these parameters:

ncols         1481
nrows         1314
xllcorner     -10.577897001
yllcorner     49.902509998994
cellsize      0.00833333333333
NODATA_value  -9999

I am running these four lines for loading the ascii and resizing the world.

set my-dataset "data/my-folder/my-file.asc"
resize-world 0 gis:width-of (gis:load-dataset my-dataset) - 1 0 gis:height-of (gis:load-dataset my-dataset) - 1
gis:set-world-envelope-ds (gis:envelope-of (gis:load-dataset my-dataset))
gis:apply-raster (gis:load-dataset my-dataset) my-variable

Is anyone familiar with this error? Or is there a place where I can look up what this extension exception means? I could not find it, but maybe I am looking in the wrong places.

Thanks!

Answer 1

I'm pretty sure there is an off-by-one error in RasterDataset.resample, but I've never had the time to look into it. You should be able to work around this issue by removing the "- 1"'s from your call to resize-world, i.e.,

resize-world 0 gis:width-of (gis:load-dataset my-dataset) 0 gis:height-of (gis:load-dataset my-dataset)

If that doesn't work, let me know and I'll see if I can find time to investigate further.

Answer 2

The issue was finally solved after recreating all ascii files. Even though there was no apparent difference in the old and new ascii files, the old files must have been corrupted somehow. The code in the question works fine now. Hopefully this topic is still helpful for anybody running into the same error.
