Description:

Abstract:: This coverage shows areas that were not included in the aerial photographic coverage used to generate an inventory of landslides and related downchannel effects triggered by the passage of Hurricane Mitch, October 21-31, 1998 in seven study areas in Nicaragua.
Purpose:: 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 show the areas not included in the aerial phototgraphic coverage used to document the landslide and downchannel response to the rainfall that accompanied Hurricane Mitch in seven study areas in Nicaragua.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Attribute accuracy was assured by visually comparing compilation copy with the plotted map in which the coverage of the aerial photographs was mapped.

Logical_Consistency_Report:

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.

Completeness_Report:

Completeness was assured by visually inspecting the compilation map overlaid on the plotted map looking for missing polygons.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The small scale of the aerial photographs and the method of manually transferring the extent of the aerial phototgraph coverage to the base maps dictates an accuracy of about 200m.

Process_Step:

Process_Description:: Aerial photographs taken between December 4 and December 19, 1998 under the Open Skies program of the Defense Threat Reduction Agency (<http://www>. mitchnts1.cr.usgs.gov.data.aerial.html) were used to generate the inventory of Hurricane Mitch-realted landslide activity in seven study areas in Nicaragua. The aerial photographs are at 1:60,000-scale, and 1:30,000-scale for portions of the Matagalpa and Jinotega/San Rafael del Norte study areas. Digital Raster Graphic (DRG) scanned images of 1:50,000-scale quadrangles projected to Transverse Mercator were used as base maps for the mapping. We mapped the extent of the aerial photographic coverage by manually plotting the field of view of each photo by inspection onto the base maps. In some cases, the base maps were enlarged to 1:25,000-scale to facilitate mapping.

Process_Step:

Process_Description:: The mapped areal extent of the aerial photo coverage was digitized, and then digitally registered to the DRG base maps.
