Description:

Abstract:

This cover contains the outlines of landslides formed during Hurricane Mitch in October - November 1998. Jeffrey Coe and Robert Bucknam mapped the landslides and related effects in and adjacent to downstream drainages. Most landslides were mapped using 1:40,000-scale aerial photographs and a Kern PG-2 photogrammetric plotter at 4X and 8X magnifications. The photographs were scaled and oriented to the topographic base map using prominent topographic landmarks and plotted on a transparent polyester overlay registered to the topographic base maps at scales of 1:50,000 or 1:25,000. In areas where landslides were very sparse, the aerial photographs were scanned with a mirror stereoscope at 4X magnification, and landslide locations were transferred to base maps by inspection. The mapped landslides were digitized manually or by an optical scanner, and the data were then digitally registered to a digital version of the base map in ArcInfo.

Purpose:

The cover shows the distribution of slope failures formed during Hurricane Mitch in one of twenty 1:50,000-scale maps within a large study area adjacent to the Motagua and Polochic Rivers. The maps may also show recent landslides that formed prior before and after 1998. When combined, the maps provide a detailed inventory of landslides over a large geographic area (~10,000 km2) of diverse geology, geomorphology, microclimates, and vegetation.

Horizontal_Positional_Accuracy_Report:

The linework was digitized manually or by an optical scanner. Landslide locations mapped using the photogrammetric plotter are estimated accurate to within 50-100 m. Locations of landslides mapped using a mirror stereoscope are estimated to be accurate to within approximately 200 m.
