1ES341 Fundamentals of GIS Final Project DUE: Monday of Finals Week Your job is to compile a complete set of GIS vector map themes, digital elevation models, and DRG’s for a select watershed in western Oregon. In addition you will calculate some basic watershed parameters from your GIS compilation and create a poster in powerpoint displaying the fine work you have completed. _________________________________________________________________________________________ Student Teams Assigned Coast Range Watersheds Amanda-Hannah 1.

West Fork Millicoma River (Coos Basin, Coos County) Instructions: All final project materials will be submitted as a separate portfolio binders. Make sure you organize your final projects by Task No., and clearly label the sections in order of appearance below. Task 1. Using the Coast Range Watersheds theme from the class website (under the final project section), find all of the subbasins that are contained within your assigned watershed. Task 2. Identify the County(ies) in which your watershed (and related subbasins) is (are) contained. Task 3. Identify all of the USGS 7.5-minute quadrangles that contain portions of your watershed. Task 4. Using ArcMap, select your watershed sub-basins from the Coast Range Watershed theme and convert them to a new, stand-alone shape file. Task 4A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new watershed subbasin theme map. Task 5. Using ArcToolbox, dissolve your sub-basin polygons into one large watershed polygon for your site. Task 5A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new consolidated watershed boundary theme map.2Task 6. Using ArcMap and the 1:24000 State Quadrangle polygon theme from the class web site (under the final project section), select all of the quads that contain your watershed footprint. Convert the selected quadrangles to a new, stand-alone shape file that can be used as an overlay on your watershed footprint. Task 6A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new quadrangle map with watershed footprint overlay. Task 7. Using ArcToolbox and the “Coast Range Streams” theme from the class web site (under the final project section), clip the stream coverage so that it forms an overlay within your watershed footprint. Task 7A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new watershed footprint theme map with stream pattern overlay. Task 8. Use the ArcMap table manager and your newly created watershed themes to determine the following watershed parameters: Total Drainage Area (sq. meters) _________________________ Total Drainage Area (sq. km) _________________________ Total Length of Watershed (sq. km) _________________________ Total Width of Watershed (sq. km) _________________________ Watershed Length/Width Ratio _________________________ Total No. of Subbasins in Watershed _________________________ Average Area of Subbasins in Watershed _________________________ Total No. of Stream Segments or Tributaries in Watershed _________________________ Total No. of First Order Stream Segments _________________________ Total No. of Second Order Stream Segments _________________________ First Order Stream Frequency (Total No. / Drainage Area) _________________________ Task 9. For your selected watershed, use the GIS web links on the class web site (plus any others that you may find) to download and assemble the following GIS themes: USGS DRG (raster) Soils (vector) USGS DEM (raster) Vegetation (vector) Bedrock Geology (vector) Roads (vector) Annual Rainfall/Precipitation (raster) Streams (vector) 9-1. As you are searching web sites for GIS data, keep track of the more interesting / successful sites that you encounter. Save, list, and print the URL addresses of your top 8 web links that you find useful in compiling your final project data. Parameters and other tasks:39-2. Define projections for all of your data files (create *.prj files and print them out to include in your project portfolio). 9-3 Convert all map themes to UTM meters, Zone 10 North (NAD_1927) 9-4 Clip each vector file so that each theme perfectly overlays the watershed boundary footprint. 9-5 Using layout with student names, quadrangle name, map theme title, scale, north arrow, legend, print the following and assemble in a neat looking package to include in each of your portfolios: Printout for each watershed A. Quad DRG’s D. Soils on DEM G. Streams on precipitation B. Quad DEM’s E. Bedrock on DRG’s H. Streams on vegetation C Vegetation with polygons labeled F. Roads on bedrock Task 10. Using the class web site resources and download links, find and assemble all of the Digital Orthophoto Quads for your watershed (Mr. Sid files are the most compact and easiest to use). Using layout with student names, quadrangle name, map theme title, scale, north arrow, legend, print the DOQ’s to include in each of your portfolios. Task 11. Using ArcView Spatial Analyst, your assembled DEM’s, and watershed themes, calculate the following watershed parameters: Minimum Watershed Elevation (feet) _______________________ Maximum Watershed Elevation (feet) _______________________ Minimum Slope (decimal degrees) _______________________ Maximum Slope (decimal degrees) _______________________ Task 12. Using powerpoint and the “watershed poster” template available on the final project links of the class web site, create a 36”x 48” (landscape layout) poster of the results of your final project. Posters should include the following text sections: I. Title, names, class
