Sorry for a late response and thank you everyone for getting back to me! I really appreciate it! The version I am using is 10.2.0.3348. Unfortunately the files are heavy (each over 2GB, there are 7) to upload. Besides, they are from the Provincial Ministry and I am not sure if I could put them in the public domain. I received the data as a geodatabase ...

Without knowing all the information (as you have already mentioned above like Version, steps you did etc.), it seems like a general problem I have had many times: The problem (maybe) is the shape itself. It´s an old buggy format, for example sometime when I have to use shapes and erase geometries when I get the same error. If you want to work with shapes ...

This can be done in a two step process... Use Merge to combine all your polygons into one polygon (tool found in the Data Management / General toolbox) Use Feature to Raster to change the polygon into a raster (tool found in the Conversion / To Raster toolbox). These are both straightforward tools. The most complicated part with Feature to Raster is ...

As crmackey notes in his comment, the first element in sys.argv needs to be the current script. You also need to use '-o' instead of 'o' as your first argument for gdal_merge Try: sys.path.append('C:/Python27/ArcGIS10.2/Scripts/') import gdal_merge as gm workspace="D:/Satellitendaten/rapideye/img/testregion/cannyedge/out/" os.chdir(workspace) ...

I would make a new layer by buffering your polygons by x-meters and checking the 'dissolve' option. Make sure your new layer is singlepart geometry and then give each of your buffered polygons a unique ID. Next perform a spatial join of your buffers on your original polygons to attribute the originals with the ids from your buffers. Finally dissolve your ...

Using the Dissolve (Data Management) tool on your ID field for your lines, you can specify whether the resultant lines will be multi-part or single-part via the multi-part parameter. You can also dissolve or unsplit lines via the unsplit parameter.

I doubt your process "gets caught in a loop", I think it will just take a long time to complete as your rasters are actually quite large. Those "small rasters totally less than 100mb" are roughly 2Gb uncompressed, each. The layer properties you included in your question show that particular raster has dimensions of 36702 cols, 14147 rows and 4 bands with ...

ECW comes from Erdas and is not fully supported by GDAL without Erdas licence. According to the help : The ECW 4.x SDK from ERDAS is only free for image decompression. To compress images it is necessary to build with the read/write SDK and to provide an OEM licensing key at runtime which may be purchased from ERDAS. So you can decompress your ...

When specific shapes exhibit strange behavior as a result of a geoprocessing tool or editing operation, one of the first things to check is whether they have valid geometries. Geometry errors can result in null results or other errors. QGIS has a Check Geometry Validity tool, and another option would be to load it into GRASS and run v.clean. There are ...
