comment Convert manual colored maps to vector
it's all pixels, right? Do you have a little snippet you can post of what the scanned image looks like?

comment Convert manual colored maps to vector
this is almost like land cover classification - at least some raster re-classification can be done once you've scanned the map - how many colours are you dealing with? Once reclassified to 'just' those colours, converting to vector based should be easy...

I just tried this and it works great - it will do us well when we're using QGIS/PostGIS... thanks again!

comment Accuracy of coordinates from 1960's
@mc1972 are the LAT/LON values in decimal degrees, ie. they LOOK like normal LAT/LON values in WGS84 (ie. 37.285543, -100.340014) ? Or do they look like something different?

comment Mosaicking many tif files in ArcMap for ENVI
I'm not sure if ENVI can use a mosaic dataset (MD), but if you used the MD as a 'middle man', ie. loading all your rasters into an MD then exporting that into a ENVI-friendly format, that could take some of the work out...

comment Accuracy of coordinates from 1960's
would those coordinates have been based on NAD27? If so, could they be plotted in say QGIS using EPSG:4267 then re-projected to NAD83?
