This was a two-part lab preparing for a project concerning the coal-mining process of mountain top removal in the Appalachian Mountains of West Virginia. The first part of the lab involved learning about LiDAR as well as creating and viewing LAS datasets in ArcMap. Different point symbology and different filters impact how useful the information can be.
The second part of the lab involved creating stream and basin features from USGS Digital Elevation Models (DEMs). A mosaic of four DEMs which Group 3 will be using this module was created and clipped to the extent of the class's study area. Several tools of the Hydrology toolset of Spatial Analyst were used then:
1. Fill tool to fill in low spots/pooling areas
2. Flow Direction tool to assign values to each pixel indicating direction of flow across the individual pixels
3. Flow Accumulation tool to indicate the number of other cells flowing into each cell (to show possible streams)
4. Con tool to eliminate features which likely are not streams
6. Stream to Feature tool to create streams layer
7. Basin tool to create watershed layer
The created streams and basin layers are depicted in this map:
