Identification_Information: Citation: Citation_Information: Originator: Los Angeles & San Gabriel Rivers Watershed Council Publication_Date: July 15, 2007 Title: invasive_poly Geospatial_Data_Presentation_Form: vector digital data Description: Abstract: Invasive plant surveys within coastal watersheds of Southern California Purpose: Funded through CDFA, this data is intended to represent a comprehensive collection of digitally available invasive plant surveys completed over the past seven years for the coastal watersheds of Southern California. For any given region, there can be anywhere from one up to seventy different species inventoried. This mapping project is part of a larger statewide effort through CDFA and the California Invasive Plant Council to compile and integrate invasive plant data into a statewide database.

Species that were unfamiliar to the field surveyors were marked in the database as "other" with a "?" in the comment field. Photos were taken of these species and sent to Rancho Santa Ana Botanic Garden for a positive ID. Once confirmed, records were updated to reflect any changes. Approximately 80 records within the "other" class still need a positive ID. Accuracy of the attribute PERC_COVER has yet to be determined. Percentages were based on a rough visual interpretation from the ground. In some cases, values may be moderately under or over-estimated because of issues with access to property and/or line of sight due to other vegetation cover, structures, etc. This holds true for the ivy species in particular. Logical_Consistency_Report: No tests for logical consistency were conducted. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Positional accuracy varies between sources due to the different data collection techniques implemented and conditions in which the data was originally collected. For those sources that used high resolution arial photography as a base source, data collected is no better than that of the photography used to delineate extent. For a majority of the datasets compiled, sources appear to have used 1 of 4 methods for initial data collection. These include (a) field mapping on mylars over printed aerial photography/topo maps, (b) field mapping with a GPS unit, (c) field mapping with an integrated Tablet PC/GPS, or (d) in-house pre-surveys using heads-up digitizing of high resolution vertical aerial photography combined with hi-res oblique photography as reference, followed by field checking using a Tablet PC/GPS. Cartographic offsets may be present in the data due to several conditions including (a) GPS accuracy affected by quality of unit, and/or poor signal due to canopy cover, terrain, cloud cover, time of day, etc., (b) scale and legibility constraints within basemap aerial photography, (c) field mapper interpretational errors due to line of sight issues caused by dense vegetation, terrain, structures, etc. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: varies (~.5m-10m) Horizontal_Positional_Accuracy_Explanation: This value is a rough estimate based on short qualitative data reviews of various areas using high resolution photography. No further testing was performed.

Process_Step: Process_Description: A personal geodatabase was created and domains were set for the "common name" field. Using domains helps ensure data integrity by limiting the choice of values for a particular field. Validation for coded value domains is accomplished by restricting the user to choose field values from a dropdown list. The geodatabase and relevant base information was then exported out of ArcGIS via the ArcPad toolbar. The AP toolbar automatically generates forms using the attributes we defined in our geodatabase. The project data was then copied onto one of our field tablets (Xplore ix104C2 or Xplore ix104C3). Process_Date: 20060801 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jason Casanova Contact_Organization: LASGRWC Process_Step: Process_Description: Field surveyors mapped plant populations using one of the following Tablet PC/GPS units: (a) Xplore ix104c2 with bluetooth Trimble XB receiver or (b) Xplore ix104c3 with hard-mounted Xplore GPS module. Surveyors used their GPS location in conjunction with high-resolution aerial imagery within ArcPad to identify and map ~30 species of invasive plants within various locations of the San Gabriel foothills of Los Angeles County. Tracklogs within ArcPad were used to monitor coverage area and time spent mapping each area.
