Series Name: Land Cover / Use I

Description:

Abstract:

The MDNR 1978 land cover files represent a compilation of data from county and regional planning commissions or their subcontractors. The original 1978 Landuse CAD files have been converted into a GIS environment. Files are formatted for the entire state by county in the Michigan Georef Coordinate System.

Purpose: This data set is intended for general planning purposes. It is not intended for site specific use.
Supplemental Information:

Data editing, manipulation, and evaluation has been completed by the Michigan State University Center for Remote Sensing and GIS and by MDNR. Files have been checked, by MDNR, against the original MDNR digital files for errant land cover/land use classification codes. Edits were not made to the original CAD files derived from data received from the counties and regional planning commissions.

## Data Quality Information

Section Index

Attribute Accuracy:

Attribute Accuracy Report:

ArcView was used to link attribute tables from each coverage to a database table of codes. Codes that were found in the attribute table but not in the database of codes were flagged. Polygons with '0' or '000' labels were identified through visual inspection and interpretation of the aerial photos. Original MDNR CAD files were visually compared to the coverages. If a discrepancy was found, the attribute value was updated to reflect the code in the original MDNR file. A unique list of codes for each county was developed and compiled into a unique list for the state. This list was reviewed and edited based on the Current Use Inventory Classification System Definitions, as amended by MDNR, and the forest classification system developed by Davis. This revised database of valid codes was later used to update all county attribute tables.
Original data compiled by county and regional planning commissions was not checked or edited, resulting in variations in quality and consistency between counties.

Process Step:

Process Description:

Develop countywide coverage. Convert MDNR Land Cover/Land Use Township files from C-Map format to ESRI ArcView shapefiles.
To correct inconsistencies on field names and structures, the MSU Compress program (Compress.exe) was used to standardize the database structure. Then, the C-Map to GIS program (CMAP2GIS.exe) was run as a batch program using the to_gis.exe program.
Each C-Map township file on a county directory was converted to an ArcView shapefile. Each shapefile was then converted to an ARC/INFO file.
Join survey townships together to create a county-wide coverage.
twnjoin.aml (if data is ArcView Shapefile format) or twnjoin2.aml (if data is ARC/INFO coverage) These programs are used to join townships and township level land cover files. The program converts shapefiles to
coverages. From the subsequent list of coverages in the folder, the coverages are joined using the mapjoin command.
Eliminate joined coverages and dissolve lines. Final product is a joined coverage without slivers and unnecessary lines.

Process Description:

Label validity check and comparison to MDNR CAD files.
Used ArcView to join county coverage polygon attribute tables to a database of valid codes. Flagged polygons with invalid codes and checked them against original MDNR land cover/use CAD files. Corrected coverage labels that did not match MDNR file labels. Coverage and MDNR file labels found to be invalid were noted. Compiled database of all codes found (valid and invalid). This database was later compared to the database of valid codes. See code validity varification process for details.
