Assignment 5



1. For this assignment, I used ArcView 8x toolbar in ArcCatalog to import three interchange files of the Pecos River system.
2. I added this data to a new map, then utilized the Query Builder to select the Pecos Headwaters Hydrologic Unit (HUC# 13060001). Then I exported that data to a new shapefile, and added as a layer to the map.
3. Using the Select by Location menu option under the Selection menu, I highlighted the Pecos River.
4. I obtained data on stream gauges in the Pecos Headwaters from http://waterdata.usgs.gov/nm/nwis/sw, and pasted it into an Excel spreadsheet. Data included the site identification number, site name, and the latitude, longitude, and altitude of the station.
5. In order to be able to import the table into ArcGis, I cleaned it up and saved it as a DBF4 file.  Then I added the .dbf to the map.
6. Because the gauges were not in the same projection as the underlying layers, they were not located along the river at first. This was corrected by utilizing the ArcToolbox to project the stream gauge layer in US Albers Equal Area Conic.
7. Finally, I added labels to the gauging stations, and changed the size of the Pecos River and the location of the labels so the gauging station names would be clearly visible.
