I'm working on a magazine article for ACSM Bulliten entitled "Creating<br>
Value From Raster Data". The target audience will be land surveyors. I<br>
was hoping some of the OSGeo guys would be able to help me with a few<br>
questions as I do my research for the article:<br>
<br>
<br>
<br>
- Are there any open source alternatives to automated feature<br>
creation from raster data, such as is possible with ENVI<br>
(<a href="http://www.ittvis.com/ProductServices/ENVI.aspx" target="_blank">http://www.ittvis.com/ProductServices/ENVI.aspx</a>) ?<br>
<br>
- Does anyone know of research or work being done with the<br>
development of open source algorithms and programming libraries to<br>
enable automated feature creation from raster data?<br>
<br>
- Can you think of ways to create value from raster data other<br>
than extraction of vector features?<br>
<br>
<br>
<br>
Thanks for any suggestions and information.<br>
<br>

Search for Support Vector Machines (SVM) and Image Classification papers. OpenSource projects that are great at this are OpenCV and libSVM among many others...</div>
