I have been having problems trying to import grids into ArcView even though I have both 3D Analyst and Spatial Analyst extensions. I produced FLT binary grids in Oasis but kept getting an error described by ArcView as a syntax error. I then tried an ASCII form of the grid and was able to sucessfully read it into ArcView. The plot thickens when I tried to read a similar ASCII grid using the same version of ArcView on a laptop at home. At that point I got really frustrated and began to consider whether something wierd might not be going on. I began to load other extensions into memory on the off chance that it might somehow help. To my surprise and chagrin it does help. Unfortunately, I still do not have any rational for exactly which extensions should be loaded. I found that in order to read the ASCII grids, I had to have the "geoprocessing" extension loaded in addition to 3D Analyst and Spatial Analyst (I do not know if I really need both of them). In order to read the binary grid from Oasis, I had to load an extension related to images. The only clue that I had is that other people apparently had no trouble reading the grids. The mystery to me is why 3D analyst or Spatial Analyst would not be sufficient by themselves. This whole process has been extremely frustrating and I pass on this experience in the hopes that others may benefit from it and that those at Geosoft will add this knowledge to their data bank. Perhaps someone at Geosoft could investigate the whole issue and consider putting something into the help files to warn people about this. Yes, I know that none of this is a direct issue for Geosoft except for the fact that Oasis provides the export option. Now, can anyone tell me how to get shape files produced that can be read by Arcview? I have written shape files from Oasis and ArcView seems to read them but they are apparently empty. Is there some secret combination of extensions that have to be loaded? Or is there some secret procedure to be followed in the generation of the shape files in Oasis? ******************************************************************************* Joseph (Joe) S.
