- Abstract
- This data was created by combining two separate data sets, the land use/land cover layer from the Integrated Terrain Unit Maps (ITUM) for this county and the freshwater wetlands (FWW) layer generated under the New Jersey Freshwater Wetlands Mapping Program. The Arc/INFO LULC coverage has been converted to an ArcView shapefile for distribution.The ITUM land use/land cover was photo interpreted from 1986 color infrared (CIR) 1:58000 aerial photos, and delineated using a modified Anderson et al. 1976, classification system to 1:24000 rectified photo-basemaps. These basemaps complied with National Map Accuracy Standards (NMAS) as individual quadrangles but were not produced from a sophisticated aero-triangulation photogrammetric solution. Minimum mapping unit = 2.5 acres. The ITUM land use/land cover was integrated with three other sources (soils, USGS floodprone areas, and 1906 Atlas Sheet Geology) based on coincident features. The four data layers have subsequently been split out into four separate themes for distribution and use. Beginning in 1998, the NJDEP does not support the data as a single integrated ITUM theme but rather as four separate themes.Freshwater wetlands delineations were made on 1986 orthophoto quarterquad basemaps (1:12000) by photo interpretation of 1986 CIR photos. The classification system used was a modified Cowardin system (Cowardin, et al., 1979). All freshwater wetland polygons greater than 1 acre in area and all linear freshwater wetland features greater than 10 feet in width were mapped. The 1986 quarterquad basemaps meet NMAS and are orthophotos.
- Purpose
- The ITUM land use/land cover information was developed as an element of the NJDEP Integrated Terrain Unit Mapping (ITUM). This theme was developed as one of the fundamental data sets needed for environmental analysis and GIS mapping based on a department wide needs assessment.The FWW theme was mapped to fulfill a requirement of the Freshwater Wetlands Act of 1987 (Refer to metadata for FWW). The FWW data was subsequently integrated into the existing ITUM land use/land cover to produce the LULC theme.Tidal (estuarine) wetlands were not mapped as part of NJDEP's FWW mapping. These polygons were delineated as part of the ITUM land use/land cover mapping.LULC polygons are intended to serve as a resource for analysis rather than regulatory delineations. The NJDEP may change the linework based on more in depth analysis and field inspection for regulatory purposes.

- Data Quality Information
- Attribute Accuracy Report
- ITUM land use/land cover: Frequencies run to check for invalid codes. Invalid codes corrected. Nodeerrors and labelerrors functions run and corrected. Some field checking was performed. Land use codes containing ##09 require field verification. Refer to ITUM.TXT or ITUM.DOC.FWW: Some field checking was done on each quarterquad, minimum of four points. Contractor's post-scanning mylar proof sheets, and digital files, were checked by NJDEP staff against original delineation mylars for completeness and accuracy. Line and polygon codes on proof sheets and in digital files were also checked against original delineation mylars. Errors were corrected to achieve 100% coding accuracy.LULC: Completed LULC layer was checked for valid codes, labelerrors and nodeerrors. Area calculations done on all non-tidal wetlands mapped for the FWW mapping effort to insure inclusion of all FWW polygons and FWW codes in final LULC layer. On line visual comparisons of final integrated LULC layer with original FWW and land use/land cover layers also performed. Polygons below .25 acres generated through the integration process were eliminated.
- Logical Consistency Report
- Data has not been systematically plotted on mylar and checked to basemap. Nodeerrors, labelerrors and slivers resolved. #9 codes not field checked.
- Completeness Report
- The project as originally designed was completed for the entire county.
- Horizontal Positional Accuracy Report
- National Map Accuracy Standards (NMAS) -- Data has been systematically plotted on mylar and checked to 1986 photo basemap. Nodeerrors, labelerrors and slivers larger than .25 acres were resolved (see Section 1.2.3 SUPPLEMENTAL INFORMATION). Features are within +/- 80 feet or better from locations on the 1986 photoquads.

- A mylar manuscript was made for each FEMA map panel. The high velocity V line and road intersections were delineated on the mylar. Tics ids were identified at these intersections on the manuscript and orthophoto. The V line is defined as "Areas of 100 year coastal flood with velocity (wave action)." The manuscript mylars were scanned, vectorized and edited. The unique tics on the orthophoto were digitized and added to the transformation file for each panel. Each panel was then transformed and appended and checked to the photoquads.
