This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.

The passage of Hurricane Mitch through Central America in October and November 1998 caused widespread and devastating flooding and landsliding. In this data set we document the landslide and downchannel response to the rainfall that accompanied Hurricane Mitch in seven study areas in Nicaragua.

Attribute accuracy was assured by visually comparing compilation copy with plotted map in which the landslide styles were color coded.
The small scale of the aerial photographs used for generating the inventory, and the mapping method of manually transferring the areal extent of observed features to the base maps, dictates that the locations of the landslide features are accurate to within about 200m
Completeness was assured by visually inspecting the compilation map overlaid on the plotted map looking for missing polygons.
Registration accuracy was checked by inspecting plots of the data and graticule overlaid on a Digital Raster Graphic (DRG) of the base map. Topological consistency was checked by assuring that all data polygons had one label point.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- Should only be used in maps whose scale is smaller than 1:50,000.
