I have some USGS DRG topographic maps that I downloaded. I want to create a raster that has vecotr and/or site data plotted on the topographic map. Then I will export the raster to create another DRG topographic map that has my data plotted on it. I am wondering how to do that. One approach would be to display the raster data, vector data and then the site data and labels. Then use the png driver. That seems to be only suitable for a small area not a whole 7.5" topo map. The other approach is to use the cell driver. That generates a file but it is not geo-referenced. If I could modify its region from (x y pixel coordinates) back to my NAD27 topo then that might work. That is not too straightforward.
I thought about using mapcal. I would convert the site data to a raster map then I could superimpose that on the topo raster. That does not seem to work becasue there doesn't appear to be a feature to convert site labels to raster.
What would work out best is if I could just reference my whole region in a display where I have already plotted the vector and site data on top of the raster, and create a raster layer of plotted data. I could then export this layer to a geo-referenced tiff. Is there any way that I could reference the displayed cells with site data on it so that I could use mapcalc to create another raster layer?
