purpose:
To delineate geologic contacts and thematically depict geologic age of outcrops in Bangladesh. This shapefile is also used in an ArcExplorer project. The data provide government, geologic community, consultants, and the general public with an important geological base for small scale natural resource surveys, exploration and analysis.

evaluation Method Description  1. Original geological map is of 100 m. maximum accuracy (0.1 mm on paper map of 1:1,000,000 scale). 2. Scanned images are of 200 dot/inch resolution (0.1 mm on paper). Therefore fuzzy tolerance for CLEAN command in ARC/INFO was set to 300 meters (three pixels). 3. Several steps were taken to vectorize scanned images as follows: 3.1. A latitude/longitude grid with cell size 1 * 1 degree was projected to Lambert Conformal Conic projection and then used to create an ARC/INFO point coverage. That point coverage was used as a reference for ArcInfo REGISTER and RECTIFY programs. Overall RMS error was 250m. The vectorized coverage was edited and attributed in Arcedit using the color image of the source map as a background guide. 3.2. Polygon boundaries and geologic attributing of the ARC/INFO coverage were verified and corrected by comparing it with to the color image as a background. ESRI's ArcWorld 1:3M data set is too small in scale for position accuracy estimation since original map was of 1: 1,000,000 scale,but for estimating relative positional accuracy such a comparison has been performed. Overall relative position error was estimated by randomly selecting a set of locations on the ESRI World country coverage and comparing it with the state boundaries on the final geology coverage (b_geo). RMS error is 0.9 km (0.9 mm of the original paper map).

evaluation Method Description  DATA PROCESSING STEPS This map was compiled from Md. Khurshid Alam, A.K.M.Shahidul Hasan, and Mujibur Rahman Khan (Geological Survey of Bangladesh), and John W. Whitney (United States Geological Survey), 1990, Geological Map of Bangladesh: Geological Survey of Bangladesh Publication, scale 1:1,000,000. 1. Original map was scanned on large format Ideal scanner in color mode with resolution 200 dpi. 2. The scanned image was transformed to Lambert Conformal projection by ArcInfo REGISTER and RECTIFY utilities. 3. Reference points for transformation were latitude-longitude crosses taken from paper map and compared with the same crosses projected to Lambert in ArcInfo PROJECT utility. Overall RMS error of transformationwas 250 m (0.25 mm on original paper map). 4. On-screen digitization was performed using a rectified image as a backdrop in ArcInfo ARCEDIT. 5. Geological attributes were assigned to GLG item of Feature Attribute Table (FAT) of geology coverage. 6. Base map data layers - rivers, lakes, cities - were digitized as separate coverages. 7. All the ArcInfo coverages were projected to Geographic and converted into .E00 files, then imported to ArcView by IMPORT 71 utility and saved as shape files.

measure Description  Polygon topology. Each polygon has one unique label point with unique id, there are no dangles. Polygons are bounded at perimeter of extent, including areas attributed as water and where geologic age is not shown. The coverage has been topologically cleaned and built in Arc/Info 8.0.2.
