For Texas cavers, make sure to visit the TNRIS site, as well.
It has Texas topos and other cool stuff. Something new (reminding me that I need to visit such sites frequently) is 0.5-meter resolution aerials of the all or most of the state. (Sometimes things on TNRIS are a little less than intuitively simple, as well.) Pretty small karst features will show up at that scale! I downloaded one quarter-quad, half-meter resolution image, but I couldn't open it in my antique Arc-View program. But I could view it nicely by right-clicking and opening it with my Google Chrome browser. (It makes Explorer crash.) I would check Google Earth before going to the trouble of downloading lots of these images, but it might be worthwhile if you need a better aerial view of something on a particular quad. Or it may be easy in a way I know nothing about Roger Moore -----Original Message----- From: Mixon Bill <[email protected]> To: Cavers Texas <[email protected]> Sent: Tue, Dec 8, 2009 9:55 am Subject: [Texascavers] USGS topo downloads At least I figured out how to download an image of a topo map by name from http://libremap.org/, something I never came anywhere near figuring out at the official site http://seamless.usgs.gov/index.php.
