Metadata created using Minnesota Geographic Metadata Guidelines
| Originator | Remote Sensing and Geospatial Analysis Laboratory, University of Minnesota |
| Abstract | Raster-based land cover data set derived from 30-meter resolution Thematic Mapper satellite imagery. Classifications are divided into three levels. This is the level-1 map. The coverage consists of 5 classes including: urban/developed, agriculture (planted or cultivated), forest, non-forested vegetation, water. |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | The data set has an overall classification accuracy of 95% for level-1 classification. | |||
| Logical Consistency | Erdas/Imagine .img file or GeoTiff .tif file | |||
| Completeness | Data provides complete coverage over the stated extent of the data | |||
| Horizontal Positional Accuracy | RMS error is less than 1/4 - pixel or 7.5 meters | |||
| Lineage | Production notes for TCMA_LandCover_Level-1_2000.TIF: Landsat Thematic Mapper multi-temporal imagery was classified with ERDAS/Imagine software. For the level-1 classification, an unsupervised classification was performed to subdivide the data into 100 clusters. The 100 clusters were then grouped into the 5 classes of level-1 land cover by recoding and rule-based spatial analysis. Single, isolated pixels that produced a salt-and-pepper effect on the classified imagery were removed in a post-processing step. |
