The Government decided to estimate the extent of land area destructed and to identify the real land owners using GIS. Which analytical capabilities of GIS can be made use of for each purpose? Explain.
Answer» To estimate the area of land destructed, buffer analysis can be used. The spatial data of the area of landslide are subjected to buffer analysis, and a special circular zone is created. This helps to estimate the houses and agricultural lands of the area. To find the real landowners, overlay analysis can be used. Overlay analysis is used for under-standing the mutual relationship among the various features on the earth’s surface and the periodic changes undergone by them.
