Process_Step:
Process_Description:
Establish base of developed land use based on re-defined attributes of the DWR data and some FMMP data where DWR data was unavailable. Used GAP and LULC to supliment developed land classes where neither DWR nor FMMP where available.
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. This was done using ARC/INFO polygon overlay and topology editing tools (JOIN, ELIMINATE DISSOLVE).
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.

Process_Description:
We added a class for retired farmand and used data and maps from Westlands Water District and the U.S. Departmen of Interior Land Retirement Program to reclassify retired farmland in Fresno, Kings, and Tulare counties. This was done through ARC/INFO UNION, ELIMINATE, and DISSOLVE.

Overview_Description:
Entity_and_Attribute_Overview:
To normalize the attribute data between sources, we cross-walked their native classification to a common classification based on the USGS Anderson level II classification system (Anderson et al. 1976). This classification system was modified to include classes of interest in the San Joaquin Valley such as retired farmland, idle farmland, desert scrub, and Valley-foothill riparian communities.
