Description:

Abstract:

The North Carolina Center for Geographic Information and Analysis, in cooperation with the NC Department of Transportation and United States Environmental Protection Agency Region IV Wetlands Division, contracted Earth Satellite Corporation (EarthSat) of Rockville, Maryland to generate comprehensive land cover data for the entire state of North Carolina. EarthSat was awarded the base/municipal area deduct contract in response to request for proposal (RFP) number 503768, issued 12 July 1995.

Purpose:

These data were created to assist governmental agencies and others in making resource management decisions through the use of a geographic information system (GIS).

Supplemental_Information:

Twenty-two TM scenes were acquired from EOSAT Landsat Thematic Mapper (TM) and used by EarthSat to produce land cover classification. See full documentation for this data layer in report, "Comprehensive Land Cover Mapping for the State of North Carolina: Final Report," March 1997, Rockville, Maryland: Earth Satellite Corporation.
Revisions and updates to this layer include: 1.) Revision date: June 12, 1998 - Removal of a pixel-wide sliver of no data between the Laurinburg and Elizabethtown 100k sheets. The error first occurred during the clipping process of the statewide landcover arc/info grid with the two 100k neatline boundaries. The problem was rectified by clipping the adjoining two 100k's as one grid, vectorizing that grid, and then clipping by each 100k neatline.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Raster pixels were assigned information (land cover) classes by undergoing an unsupervised classification in Erdas Imagine 8.2. The resultant single-band image signature file was exported and formatted to use with Arc/INFO Grid's dendrogram function. A summary function in Erdas Imagine 8.2 corresponded land cover class with pixel value at which the land cover data point was located. The land cover class was recorded on the dendrogram until all data points were assigned a spectral class. Information class was assigned to spectral class by majority of points within the spectral class and/or by spectral similarity. Full process description can be found in EarthSat's final report to NCCGIA, "Comprehensive Land Cover Mapping for the State of North Carolina: Final Report," March 1997.
After processing each scene was raster edited to alleviate errors and provide for a consistent land cover surface. After an initial accuracy appraisal the scene was filtered to reach the minimum mapping unit (MMU) of 6 pixels for water and 12 pixels for other land cover types.

Quantitative_Attribute_Accuracy_Assessment:

Attribute_Accuracy_Value:

Filtered Database with Neuse-Tar/Pamlico: 78.25 Filtered Database without Neuse-Tar/Pamlico: 86.68

Attribute_Accuracy_Explanation:

The land cover surface was recoded to collapse the 23-land cover classes into the 9-accuracy classes. A summary matrix was recorded to list the user and producer accuracy for the entire scene, for both filtered and unfiltered databases.

Logical_Consistency_Report:

Using ESRI's Arc/INFO and ArcView software, and Trimble Navigation's Direct GPS for ArcView and PathFinder 3.0, data points were attributed with land cover class and rasterized for use in the classification procedure. Pseudo-color single- band images (4,5,3 RGB) were created in an unsupervised classification and information classes assigned based on majority of field data points within the spectral class and/or euclidian relationship of the means of each spectral class.

Quadrangle neatline boundaries were used to clip the landcover vector data

Process_Step:

Process_Description:

Land cover database derived from two co-registered multi spectral Landsat 5 TM pairs, leaf-off and leaf-on, and classified using field and ancillary data. Six bands (1-5 and 7) were stacked to produce a single 12-band raster image (bands 1-6 leaf-off). The Erdas Imagine ISODATA algorithm was applied to the 12-band image to generate 240 spectral class signatures. The Imagine maximum likelihood classifier was then applied using the resulting signatures to assign information (land cover) classes to the spectral classes. Arc/INFO Grid 7.0.4 dendrogram function was used to produce a paper spectral tree showing the euclidian relationship of spectral classes; land cover classes based on field data collection activities and available ancillary data (both of which not reserved for final accuracy appraisal, 40% of each class for each scene) falling at each spectral class were recorded and information class assigned based on majority and/or spectral relationship. Raster editing was interactively performed to correct for spectral confusion and misclassification.
A change order was delivered to EarthSat in April 1996 to accelerate classification for the Neuse-Tar/Pamlico watershed. This dataset was incorporated into the final statewide land cover but because of enhancement to processing techniques and correction of some errors a separate, enhanced statewide database was also provided (that did not have the earlier provided Neuse- Tar/Pamlico watershed land cover classification database).
Each scene underwent accuracy appraisal before being accepted for use in the final statewide database. Once accepted, scenes were filtered to reach the minimum mapping unit (MMU) of 6 pixels for water and 12 pixels for all other classes. Imagine clump and eliminate routines were used to reduce insignificant data and filter information class assignment.
A hierarchy of scenes was determined based on obstructed areas, scene dates, and classification results. Additional raster editing was performed to enhance data quality and interactively correct any remaining inconsistencies or spectrally confused areas. The municipal vector was rasterized and mosaicked with the final scenes and recoded to land cover class 10 (thematic class 24).

Process_Description:

NCCGIA received one statewide ERDAS Imagine (.img) file on 8mm tape. The statewide raster data was converted into an ESRI Arc/Info grid format, using the Arc/Info command "imagegrid." The grid file was then clipped by USGS 1:100,000 scale neatlines for every mapsheet in the state using the "gridclip" command in Arc/Info's Grid module. Each gridded quadrangle based file was then vectorized by using the Grid module's "gridpoly" command. The resulting item in the polygon attribute table (.pat), "grid-code", was then used as a join item to add thematic class, landcover class, and description to the .pat. Process begain 19980212.
