Groundwater Potential Mapping

Mapping of groundwater is essential in planning of water resources development, use, and management. The knowhow of potential distribution of available groundwater bodies is hence vital here. The mapping of amount of permanent water resources in aquifers can produce the groundwater potential distribution. Remote sensing and geographic information system (GIS) in combination with vertical electrical

Digital Elevation Model

Height on a certain point of the earth surface is represented by an elevation above certain datum such as mean sea level. This elevation varies as one tend to move from one point to another on surface of earth. The earth surface is highly undulate which cause these variations in the heights. Elevation of earth

Coordinate Systems

Coordinate of an entity is the most important feature of data in GIS and remote sensing. This only can make possible the exact location of each feature expressed by the data. In a simple Cartesian coordinate system there are x axis and y axis intersecting at right angle where the intersecting point is origin. The

Free and Open Source Software (FOSS) for GIS

People doing remote sensing and GIS analysis should be grateful for many freely available software around the world and huge numbers of peoples volunteering to develop them. So using FOSS, will not only save your money but these many people in background will solve your problems. An open source application by definition is software that

Landslide Hazard Zonation

The process of landslide hazard mapping requires information regarding the distribution of landslides in space and their temporal history along with the knowledge of factors that contributes in the process of slope failures. The contributing factors includes geology, topography, climatic conditions, geomorphology, land use land cover information, and anthropogenic disturbances of the location of interest.
