Viewing Grids

Recommended Posts

Hi

I am experencing some issues with Mapinfo/Vertical Mapper (v9 & v3.1). When, for instance, trimming grids to a polygon as attached. The resulting view of the grid shifts up and to the left, although when checking the levels they appear to match that of the original grid. Null values are given in the areas where the grid is shown differently than before. Also, in areas where the grid says there is no information, levels values can be obtained and match that of the original. This suggests that the .grd file is ok but the raster imaging in mapinfo is adjusting the registration.

Has anyone else experienced this problem???

Any suggestions would be appreciated.

Thanks

Tony, I'm not sure, but I suspect this is a projection problem (I've been waiting for a response from our GIS guys before I got back to you, but they're not sure). If the problem is still there check that the projections of the different VM layers you have are in the same projection.
