Topo maps

And on a sad note, TopoZone is dead.  Taken over by Trails.com on a fee subscription basis.  They'll give you a 14-day free trial, but apparently no more free topos.  I wonder how many links to maps I've posted on BBC using topozone.  :eusa_think:

Try these free downloads

http://www.tnris.state.tx.us/datadownload/download.jsp

24k, 100k, 250k scale collared (with border overlap) or collarless (image to the margin of the quad only) digital raster graphic topos and also orthophotos.
If you have the GIS software to use them: digital elevation models (DEM) and contours shapefiles

I used to use Topozone a lot for providing links to locations, or to look up lat/lon for a specific spot.  MapTech.com is the best free alternative for that feature I've found so far.  An example:

Thanks, BIBEARCH!  I have Topozone bookmarked and used it many times in the past.  Will drop their link and hyperlink this one.  Thanks, BBH

Love that website. I think I've downloaded the whole state from there. Beautiful thing about their stuff is that it is all georeferenced. I downloaded Global Mapper from a link on the Corps of Engineer site, and the topo maps here will load into that and allow you to layer the DEMs and your GPS track all together. The free version just won't let you save the data, but you can print from it.

Topozone has become part of trails.com, so no more free topos without a subscription.  :icon_frown:
