The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

The MANZ spatial database and map layer was produced by CTI from 2010 imagery using 21 map units that were directly cross-walked or matched to their corresponding rUSNVC plant association/alliance or land cover types. The final map layer was assessed for thematic accuracy by creating contingency tables and the final overall accuracy of the map layer was determined to be 96% with a Kappa value of 95%. The vegetation mapping was conducted at MANZ in two phases. The first phase conducted by the USGS Fort Collins Science Center created the primary vegetation and associated spatial data layers using the 2005 NAIP Manzanar NE DOQQ imagery (acquired on September 3, 2005 from the Cal-Atlas Geospatial Clearinghouse at http://atlas.ca.gov/). Preliminary mapping was conducted by the USGS through a semi-automated process using a combination of the ENVI Feature Extraction Module (ITT Visual Information Systems, 2008) and ArcGIS software (ESRI, 2008).
