Eric a blogger from LA kind of kicked off this post. I like to cruise other blogs, and a link to Cartifact was incredible--homeless maps and more. I love maps, especially good maps. This all seems a little disjointed but it is interesting seeing how the rest of the world lives. Both Eric and Cartifact have some interesting finds.
Of course interesting and relevant are two different things. Oklahoma. Google Earth is the free download and you can get a pretty good idea of the state with this.
I like the department of wildlifes site for Oklahoma's mammals, birds, reptiles and amphibion information.
The USDA Forest service has some maps (roadless maps). Too bad they don't have a more extensive collection. Becareful, this site can bog your machine down.
Today Water watch is showing normal precipitation. Water watch is a map of real-time streamflow compared to historical streamflow for the day of the year for Oklahoma. Also at the USGS water site is
Map of flood and high flow condition
Ground water watch
Water quality
Drought watch
Seismicity of Oklahoma and other quaky info from USGS
Terraserver has a great aerial and topo map site
The USGS national map viewer
Oklahoma's Aquifer info and maps
NOAA's Weather map
NOAA's serious data tables on average everything to do with climate
Make a map with National Atlas.gov This is a great source.
OTC hiway bypass info--I've not quite figured this map out, but it might come in handy for something
There is an endless supply of maps on the web. I'm signing off for the night. I'm sure I'll run across more to add at a later date.
