GIS & Mapping

The graphic below says it all, the Michigan Department of Environmental Quality has mapped wetland losses in the state; some counties in Michigan have lost over 90% of their wetlands, primarily during the last century. Click here to jump to the Michigan Radio article.

Michigan Wetland Losses
This morning, I found a site dedicated to geospatial analysis that I thought I would pass along.  It illustrates the broad range of applications that remote sensing can be used for, and how to best work with large datasets.  Although postings are sporatic, it is now bookmarked as one of my "GDAL goto" sites since it offers great ideas, approaches and tips on analyzing GIS data.
The  post about publishing 3D DEM's online immediately caught my attention. I have been considering displaying a  3D NVIZ DEM created in GRASS GIS online, but couldn't determine the best way to get it done; this looks like a reasonable workaround.
The posts Using GDAL with Python: a basic introduction is something that I have yet to attempt, but am looking forward to learning more about. Also there is a helpful post about Installing GDAL on Ubuntu , which admittedly, is better than my own.
Enjoy.

Just a quick shoutout to PythonAnywhere!  I have been tinkering with some Python code for a web app and needed to set up Django or web2py, but didn't want to modify a live server or set up an additonal server solely for testing.   I signed up for the free service, and was able to easily choose a version of python, add modules,  set up a Mysql database or a run cron job. I added web2py in less than 30 seconds, with one eye on the game, in comparison to the grief I would have encountered setting it up on a shared server.  For my needs, I found it perfect for running a small test environment and it is highly recommended.
