California Department of Fish and Game, VegCAMP (Vegetation Classification and Mapping Program), Vegetation Classification and Mapping Program Lead 20140829 vector digital data 2009 Vegetation Map Update for Suisun Marsh Report to follow https://www.wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/700_799/ds711.zip Vegetation delineations based on photo interpretation and formal vegetation classification plus change detection. This is part of an ongoing monitoring project that the Biogeographic Data Branch of the California Department of Fish and Game (DFG), in collaboration with the Department of Water Resources and the DFG Water Branch, started in 1999 to track changes in the Suisun Marsh vegetation over time. This is the fourth update since the original map was made in 1999. All of the vegetation maps can be viewed and downloaded using the online CDFW Biogeographic Information and Observation System (BIOS) and the links to the associated reports included in the metadata. The reports can also be downloaded from the CDFW website (http://www.dfg.ca.gov/biogeodata/vegcamp/veg_classification_reports_maps.asp). The vegetation photo interpretation for the 2009 Suisun Marsh re-map was based on true color imagery that was flown at 1:7200 on June 15, 2009. To create the 2009 map the vegetation was interpreted from the 2009 aerial imagery and polygons were digitizing using heads-up digitizing (I.e. a photo interpreter manually drew polygons around each stand of vegetation) in ArcMAP 9.3 and recorded within an empty Microsoft Access Persoanl Geodatabase. Because this new protocol starts with an empty GIS data file and is not based on the manipulation of an already existing shapefile several of the mapping rules and attributes used in the old protocol that referred to the manipulation of a shapefile no longer apply. The complete report can be viewed at: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=48108. This is the fourth of five updates since the original map was made in 1999. The first update was conducted one year after the initial aerial photo-interpretation (see ds161), is described in Vegetation Mapping of Suisun Marsh, Solano County (Keeler-Wolf and Vaghti, 2000): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24570. The second update, done three years later in 2003 (see ds162), is summarized in Suisun Marsh Vegetation Mapping Change Detection 2003 (Vaghti and Keeler-Wolf 2004): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18254. The third update, done in 2006 (see ds500), is summarized in 2006 Vegetation Map Update for Suisun Marsh, Solano County, California (Boul and Keeler-Wolf 2008): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=48107. The fifth update was done in 2012 and can be viewed and downloaded using the online CDFW Biogeographic Information and Observation System (BIOS). The 2012 report is not yet available to the public.

Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.1.9270 The vegetation photo interpretation for the 2009 Suisun Marsh re-map was based on true color imagery that was flown at 1:7200 on June 15, 2009. VegCAMP first received this imagery on March 22, 2010 as 73 individual flight line photos. It was discovered that the orthorectification process resulted in a spatial shift by as much as 10 meters when compared to the 2009 NAIP imagery. This discovery resulted in a reprocessing of the imagery to create a more spatially accurate data set. The reprocessed 2009 imagery was received by VegCAMP on October 14, 2010, at which point the photo interpretation began. Several other imagery sources were used as ancillary data including the 2009 NAIP, 2009 NAIP CIR, all the imagery available through the ImmageConnect data Library, and the 1999, 2003, and 2006 Suisun Marsh imageries. The 2006 Suisun Marsh vegetation map was also referred to often. All of the polygons were drawn using heads-up digitizing in ArcMAP 9.3 starting with an empty Microsoft Access Persoanl Geodatabase. For each polygon the vegetation type, disturbance level, and overall vegetation cover and vegetation height was estimated. The area in acres for each polygon was calculated using the ArcGIS 9.3 "Calculate Geometry" tool.
