| Abstract | The purpose of this study is to integrate GPS, GIS & Remote Sensing Technology for
making landslide hazard zonation map. A field survey is made with Global Positioning system
(GPS) to locate the positions of landslides in the study area. From the coordinates obtained
from GPS, a landslide map is prepared fo r the study area.
Different factors like Aspect, drainage, elevation, geology, road construction, slope,
isohyetal data, land cover and soil have been considered for the occurrence of landslides. By
using GIS & Remote Sensing Technology landslide occurrences on all these factors have been
analysed. The vector based GIS has been used for digitizing to produce thematic maps, as
analysis for study was based on the pixel based information therefore Raster based GIS has
been used for the anlysis.
The contour map has been scanned, edited and elevation values are given to it to
generate Digital Terrain Model (DTM) form it. Aspect, elevation and slope maps have been
obtained form DTM.Land cover map has been produced from the Panchromatic SPOT data.
Pixel based calculation was made by using the Information value Model. By using the
information model we obtained the information values for all classes of all factor maps. On the
basis of these information values all factor maps are recoded and matrix analysis was
performed to produce a landslide hazard zonation map.
The landslide hazard zonation map has been applied to digitize new road routes in the
study area by avoiding high hazard area. Different factors have been considered for observing
the most suitable road route. |
