Dear Michael,

I am sorry for the slow response; I am on holiday until 29 August.

I believe this problem is a bug in the tool that I introduced sometime in the last few months. I made some changes to underlying code that the tool relies on but did not go back and test the tool. I believe those changes must have broken it. I'm sorry for this mistake.

I can fix this problem in the next release of MGET but that will have to wait until I return. If you need a fix faster, you can manually edit the file C:\Python25\Lib\site-packages\GeoEco\SpatialAnalysis\Lines.py and fix the problem yourself. To do that, remove (or comment out) the following two lines of code:

        if xGeoArray.CellWidth != xGeoArray.CellHeight:
            Logger.RaiseException(ValueError(_(u'The X components raster and Y components raster have different cell heights ...

Those shoudl be lines 58 and 59 of the file you have. After deleting them, try the tool again.

Best regards,

Jason

Hi Jason

 

I'm trying to create vector shape files from u, v data set of  "Ocean Surface Current Analysis (OSCAR) Third Degree Resolution data " in ArcGIS 9.3.1 based on the GeoEco-0.8a9.win32-py2.5

 

I have extracted the u and v components from a smaller part of the "world" from a single date using clip_management function to Erdas .img format.

The 2 components have exact same extent, spatial reference system (a dummy projected system) and same cell size (0.3333333) in X and Y.

 

 

 

When I run the "Create vectors from vector components raster" I get the following message output:

Do you have clues of what goes wrong ?
