Native Data Set Environment: HP-UNIX ArcInfo

Logical Consistency Report: All polygon features are checked for topology and existence of attributed label points. Coverage checked for un-intentional dangling arcs.
Completeness Report:
All data with a minimum mapping unit of 1/2 hectare that can be interpreted from the aerial photographs are entered into the digital database. This includes features defined by the NVCS and the Anderson Level II Land Use classification. Some classes under the MMU are included due to its ease of interpretation and due to speciality of the class. Road and utility corridors and streams/canals wider that 10 meters were digitized as polygons.

Process Step:

Process Description:
MAP CLASSES: Vegetation classification was in accordance with the standards developed under the USGS/NPS Vegetation Mapping Program using the National Vegetation Classification Standard. Field work (collecting plot data) aided in the developement of the vegetation classes. Also, the Refuge had specific types that they wanted mapped. PHOTO INTERPRETATION: All map classes were interpreted from 1:12,000 scale, color infra-red photography. Photo-interpretation used the standard identification features such as tone, texture, color, pattern, topographic position, and shadow. In addition, field sample locations and their vegetation descriptions aided in assigning map class to each polygon. Photographs were examined using a stereoscope as needed. Linework was created on mylars placed over the photos. GIS PROCEDURES: The linework on the mylar overlays were transferred into the GIS database by one of two methods, either heads-up digitizing or scanning. METHOD I: Heads-up digitizing is a procedure whereby the operator digitizes by hand and eye on a computer terminal screen showing a digital image of an ortho-rectified photo. By looking at similar features on both the aerial photograph from which the classification was made and on the orthophoto, the line drawn on the aerial photo overlay is transferred to the digital image, which is registered to coordinates on the earth. This technique should produce good results except where there is little feature contrast on the orthophoto, in which case the operator must estimate the shape and location of the line work. METHOD II: Photos that cover an area with little topography or are too difficult to accurately transfer via heads-up will be scanned, ie, the mylar overlays will be scanned, not the actual photos. Before the mylar is scanned, it will be marked with control points that correspond to visible points on the orthophoto. The GIS software was used to convert the scanned mylar into a geo-referenced coverage which was then attributed and combined with the larger vegetation coverage associated with the area. The entire transfer and editing sequence was automated via in-house Arc/INFO AML programs. OTHER DATA: Quadrangle and orthophoto border coverages (bndryquad, bndryortho) were created to aid in the creation of the vegetation coverage. The mapping project border coverage (bndryproj) was acquired from the Refuge. A flightline coverage (bndryfline) was made by digitizing arcs with a DRG on screen and following lines as they appeared on the flightline index map. Field Observation, Plot, and Accuracy Assessment data point coverages (data_obsv, data_plot, and data_aa) were created by entering points with the 'generate' command using a text file of points and x-y coordinates. Refer to the metadata file for specifics on the data coverages.
