<p>FIrst off, I just started using UMN MAPSERVER and I am quite impressed with its speed advantages over ARCIMS. We are using 4.8.3 for LINUX on slackware 10.2+ using the fgs installer. I have recompiled gdal-1.3.2 with the mrsid DSDK6.07 so that I can decode .sid raster files.</p>
<p> I am testing out a migration from ARCIMS to MAPSERVER. I managed to use the axl2map converter and got the system up and working for the shp files, however the rasters are in completely different extents. gdalinfo for the .sid files returns.</p>

<p>Tiffs using mrsidgeodecode, my GIS guy, and the original geotiffs seem to support these extents. However, with the .shp,.shx,.dbf,prj,sbx,.sbx file through ogrinfo return something similar to:</p>

<p>I have tried using the different HARN and NAD27 epsg projections in the layer, but I think the problem is more basic (at least I hope it is.) since the extents are so skewed. Any help or a pointer to the right manual would be greatly appreciated.<br/>
