Maybe I am slow but How do I place a map overlay on google earth like these sites show?
Where is a list of what overlay maps they have already?

I've uploaded the topo overlays - how old are they? I can't seem to find dates anywhere on them. What a great resource.

sweet! That date makes a lot of sense based on the RR lines, canals, etc in my area that are long gone - but how can you tell the dates - are they on the map somewhere? Thx, SRO

well, i found out that they arent all 1894, some are 1893, sone 1903, etc, all from a 10 year period. if you click on the little black circle in the center of each map rectangel, it will tell you the date

When I zoom in the older map gets very blurry....If I zoom out to try to make clearer
I can barely make out locations of houses? Am I missing something? Thanks
