hi there,<br>
<br>
Today I've published *TOPODATA Index Map* [1] - a webmapping tool
designed to facilitate access to TOPODATA project data for GIS
users, and contribute to the application of this dataset in several
knowledge areas like forestry, agriculture and environmental.<br>
<br>
Technologies used: <br>
* GDAL/OGR + linux script: for tileset generation<br>
* Google Maps and MapServer: for webmapping application<br>
<br>
INPE [2] \TOPODATA [3] project offers free access to local
geomorphometric variables derived from SRTM data, throughout the
entire Brazilian territory. The refined data was derived with
geomorphometric analyses algorithms to calculate slope (steepness),
slope direction, plan curvature and profile curvature.<br>
In addition to these, a second order derivation was applied to
enhance thalweg and divides, which were overlaid on a slope
direction presentation, as input for the interpretation of drainage
features and structure. <br>
