Process_Step:

Process_Description:

The rivers and streams in this dataset were derived from a 90 meter SRTM digital elevation model of Ecuador by filling sinks and using the flow accumulation and flow direction parameters. Overlay analysis was preformed with other vector files to verify rivers and streams. Some editing was performed to clip derived streams to the edges of the DEM.
