Source_Used_Citation_Abbreviation: DWR Source_Used_Citation_Abbreviation: FMMP Source_Used_Citation_Abbreviation: LULC Source_Used_Citation_Abbreviation: GAP Process_Step: Process_Description: Cross checked, added to, and refined attribute information for urban areas from basemap established in step 1.

Source_Used_Citation_Abbreviation: LULC Source_Used_Citation_Abbreviation: FMMP Source_Used_Citation_Abbreviation: GAP Process_Step: Process_Description: Cross-checked and added to agricultural areas from basemap using more recent FMMP data. This was done using ARC/INFO polygon overlay and topology editing tools (JOIN, ELIMINATE DISSOLVE). Source_Used_Citation_Abbreviation: FMMP Process_Step: Process_Description: Added land cover classes from the GAP data within areas classified as generic "undeveloped" on our basemap from step 1. These include DWR lands classified as "Native Vegeation" or "Unirrigated Pasture" and FMMP lands classified as "Grazing Lands" or "Other Lands". Source_Used_Citation_Abbreviation: GAP Process_Step: Process_Description: Edited land cover classes for wetlands from the NWI data within areas classified as generic "undeveloped" on our basemap from step 1. These include DWR lands classified as "Native Vegeation" or "Unirrigated Pasture" and FMMP lands classified as "Grazing Lands" or "Other Lands". Source_Used_Citation_Abbreviation: NWI Process_Step: Process_Description: We built a mosaic of continuous Landsat ETM+ visible and infrared band data for our project area that was geographically adjusted to our base map. Source_Used_Citation_Abbreviation: ETM_iso Process_Step: Process_Description: We clipped the Landsat data to only the areas containing non-developed upland communities and classified the masked data to 16 categories using an Iterative Self-Organizing Data Analysis Technique (ISODATA). The two brightest and one darkest categories where converted to a shapefile. Source_Used_Citation_Abbreviation: ETM_iso Process_Step: Process_Description: We calculated the area of each individual polygon area from the last step. We converted our data to a shapefile and reviewed the data by zooming to each polygon in the reverse order of size. Where we found errors, we manually corrected the error and changed classifications using secondary sources such as the Landsat image, a higher resolution SPOT image, and USGS topographic maps. We stopped reviewing when we got down to an arbitrary polygon size of 85 ha.

This was done through ARC/INFO UNION, ELIMINATE, and DISSOLVE.
