Description:

Abstract:

This data set consists of digital data describing wetland and upland habitats in the southern coastal areas of Honduras affected by Hurricane Mitch in October 1998. The data set includes specifically the municipalities of San Lorenzo, Nacaome, Amapala and Choluteca. 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.,.

Purpose:

To provide habitat information for restoration and management effects.

1998 Hurricane Mitch Honduras Habitat Data for the Islas de la Bahia and Northern coastal region.

Geospatial_Data_Presentation_Form: Digital vector data

Data_Quality_Information:

Attribute_Accuracy:

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.

Logical_Consistency_Report:

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. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The neatline for each area 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.

Completeness_Report:

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. Data products were completed using similar systems and methodologies which are used by NWI and by USGS.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

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.

Process_Step:

Process_Description:

Cartographic phase - EROS High altitude color infrared and black/white 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.

Process_Date: 1999-2001

Process_Step:

Process_Description:

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.

Entity_Type:

Entity_Type_Label: Wetland and Upland Habitat Polygons

Entity_Type_Definition:

Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface of the land is covered by shallow water. Uplands are terrestrial systems that do not exhibit wetland characteristics.

Attribute:

Attribute_Label: Data

Attribute_Definition:

The wetland classification system is hierarchical, with wetlands and deepwater habitats divided among 5 major systems at the broadest level. The five systems include Marine, Estuarine, Riverine, Lacustrine, and Palustrine. These systems are further divided into subsystems which reflect hydrologic conditions. Below the subsystems are classes and subclasses describing vegetation or substrate, and modifiers relating to hydrology, soils, water chemistry, and man's activities.
