Abstract:
This data set consists of digital data describing wetland (including seagrass habitat) and upland habitats in the northern coastal areas of Honduras affected by Hurricane Mitch in October 1998. The data set includes specifically the islands north of the country: Guanaja and Roatan. Wetlands were classified using the Cowardin, et al., wetland classification scheme to the level of salinity modifiers. Uplands were classified using a customized classification scheme which can be cross-referenced to Anderson, et al.,. The purpose of the data set is to provide habitat information for restoration and management effects. Cartographic phase - EROS High altitude natural color aerial photographs were photo interpreted for wetland and upland habitat classifications. The photos were interpreted using a Bausch and Lomb stereoscope at 10x magnifications. Habitat layer was overlaid on NWRC reprojected NIMA base maps, compiled at 1:25,000. Cartographic work was performed using a Zoom Transfer Scope, and magnification varied according to source material scale. All cartographic and photointerpretation processes adhere to NWI standards. Digitizing phase - Mylar overlays were manually digitized using an Altek Datatab digitizer to capture the data at a resolution of at least 0.001 inches. Four control points corresponding to the four corners of the quadrangle were used for registration during data collection. Cover type features continuing onto adjacent quadrangles were adjusted to intersect the quad boundary at a common, coincident node. Attributes were assigned as the data were digitized, or in an editing session after the digitizing was completed.

Access_Constraints: It is strongly recommended that this data is directly acquired from the distributor described above or from another USGS Biological Resources Division server 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.
Use_Constraints:
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. These data are not legal documents and are not to be used as such.

Attribute_Accuracy_Report:
The attribute accuracy was tested using several methods during the data development phases and completion. During the interpretation phase, quality checks were performed at every stage. At the digitizing phase, data was tested by manual comparison of the source with hard copy printouts and/or symbolized display of the digital wetlands data on an interactive computer graphic system. Exact tolerances vary with coverages, as does the date of the processing and testing. Data has been checked and verified against original maps. This logical consistency report includes information about both general and specific topological tests and data generation dynamics in the fidelity of data. Data is inherently polygonal. Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the points of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The neatline for each quad is generated by connecting four corners of a digital file, as established during initialization of the digital file. All data crossing the neatline are clipped to the neatline and data within a specified tolerance of the neatline are snapped to the neatline. All photo-interpretable wetlands are identified and mapped using standard methodologies and equipment for the photo interpretation phases of the data development. In the upland areas, 1/4 acre wetlands generally are mapped. In coastal marsh, swamps, and bottomland hardwood areas, small open water and emergent wetlands are mapped. In general, the minimum mapping unit is from 1 to 3 acres depending of the wetland type and the scale and emulsion of the source aerial photography. Some small wetlands, densely broken marsh, and those wetlands obscured by dense forest cover may not be included in this data set. Processing of the digital data also follows conventions and standard methodologies for the time period and within limitations of available workstation equipment at the date of data development. Processing follows standard operating procedures as used, developed, and shared by the National Wetlands Inventory of the U.S. Fish and Wildlife Service. Data products were completed using similar systems and methodologies which are used by NWI and by USGS. For reference points accuracy, the accuracy for the digital data are tested by visual comparison of the source with hard copy maps, and by understanding of the hardware tolerances and processing values reported by the software used in data development. Additional checks on comparison were possible when georeferencing/rectification was done using the USGS maps, which cite National Mapping Accuracy Standard compliance.
