Vegetation - Fallbrook Naval Weapons Station [ds2958]

<div style='text-align:Left;'><div><div><p><span>This mapping effort was conducted following the guidelines described in Vegetation Mapping Protocol for Naval Weapons Station Seal Beach Detachment Fallbrook ("Protocol"; USDON 2017). Four-band (color with color IR) aerial images were collected by GeoTerra, Inc. during June 20 and 21, 2015. All flight plans and airspace access were authorized through Marine Corps Base Camp Pendleton Range Control (Longrifle). All image acquisition, processing, and ortho-rectification were conducted by GeoTerra, Inc. Final orthophotos were delivered with a resolution of 0.25 foot. This set of images served as the visual layer for photo-interpretation. The classification was generated by AECOM. AECOM conducted vegetation sampling consistent with NVC Standard methods throughout NWSSB-DF to define the subset of alliances and associations that occurred within the mapping area. Further details, and the full classification, can be found in Vegetation Mapping Protocol for Naval Weapons Station Seal Beach Detachment Fallbrook ("Protocol"; USDON 2017). No thematic accuracy assessment was performed, however field verification was conducted to establish photo-signature training for each alliance and association. Approximately 37% (accounting for 67% of the total mapped area) of all polygons and vegetation assignments were field verified. A minimum mapping unit (MMU) of 0.25 hectare was used. </span></p></div></div></div>
