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:
Executing: ArcGISLinesFromVectorComponentRasters C:\GeoPhysical\OceanSurfaceCurrentAnalysis\oscar_vel2009\u_Layer_sept15Clip.img C:\GeoPhysical\OceanSurfaceCurrentAnalysis\oscar_vel2009\v_layer_sep15Clip.img

Do you have clues of what goes wrong ?
