The rasterized maps (DRGs) were generated from original scanned maps created by NIMA (National Imagery and Mapping Agency) of the Honduras coastal areas. EROS Data Center has reformatted the 8 maps into a more widely readable format. The scanned maps were reprojected by NWRC, and targeted study areas were clipped for cartographic purposes. To serve as base maps for the habitat data. Secondarily, to serve as maps for field work. 1998 2001 Publication date Complete As needed -87.69910 -85.75294 16.57452 13.22104 None scanned maps mapping wetland uplands cartography photointerpretation ArcInfo classification mapping None Honduras Coastal Honduras Gulf of Fonseca Islas de la Bahia Roatan Guanaja San Lorenzo Nacaome Amapala Choluteca It is strongly recommended that this data is directly acquired from the distributor indicated in Section 6 Distribution Information and not indirectly through other sources which may have changed the data in some way. The distributor makes no claims as to the data's suitability for other purposes. Acknowledgement of the U.S. Geological Survey, National Wetlands Research Center as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected by users of this data. Sharing new data layers developed directly from these data would also be appreciated by NWRC staff. Users should be aware that comparison with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in mapping conventions, data collection, and computer processes over time. The distributor shall not be liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document.

Data are raster in format. Values have not be assigned to individual pixels. All areas were subsetted according to coordinates and reprojected to the same coordinate system. Data are complete. There are no known omissions to the data set. The horizontal positional accuracy is tested by visual comparison of hard copy check plots to the source materials and verifying the location of the data on-screen relative to other data layers in the same geographic area.

The images were converted into .tiff files (with an associated .tfw world file). For subsetting the project areas, the tiff files were converted into grids. Using the "grid clip" command in ARC/Info, the project areas were clipped for cartographic processes. The clipped grids were then reconverted back into tiff files. Collar information, grid and graticule were added if the intended use was for field work. If the intended use was for base map transfer, a grid, graticule and title were added. 2000-2001 Coastal Honduras Raster Universal Transverse Mercator 16 -87 0 50000 0 .9996 coordinate pair 1.27 1.27 Meters North American Datum of 1927 Clarke 1866 6378206.4 294.98 The data are raster in nature.
