AB:
Tomales Environmental Learning Center students, in conjunction with the Pacific Coast Science and Learning Center, developed
a map of the Tomales High School Subshed of the Keyes Creek Watershed using both GIS (Geographic Information Systems) and GIT
Geographic Information Technology). The map was developed for future water quality analysis projects.
To complete the task the students developed GIS knowledge using ESRI's ArcView 3.3 raster data analysis and hydrology
modeling tools. With these they created flow accumulation and flow direction maps from USGS 10-meter pixel Digital elevation
Model (DEM) files, and then created a watershed area map for the local sub-watershed that included the local high school.
The students walked and photographed the perimeter of the watershed collecting data on a handheld GPS (Trimble GeoXT with
real-time DGPS correction) and ESRI's ArcPad mapping software.
The resolution and accuracy of their hand-collected data was of a higher quality and more current than that derived from the
DEM files, and provided the base for their fiinal map.
