The study applied the soil, land and topographic data for analyzing the potentiality of land for trees /crops suitability in the Gumla district of Jharkhand, India. The remote sensing, GIS and GIS modeling techniques were used to achieve the goal. The soil fertility, soil wetness, and slope map are scientifically produced and integrated to find out the landscape suitable categories for prioritization of trees/crops scaling in the agroforestry domain. Additionally, we have examined the drift of loss of soil wetness using satellite data from monsoon to postmonsoon period up to the village level.

Planning strategies for sustainable land management require solid base line data on natural resources (soils, physiography, climate, vegetation, land use, etc.) and on socio-economic aspects. Extensive and reliable information on soil and land resources are prerequisites for efficient and effective management planning of these vital natural resources. Generation of large-scale spatial database on soil and land resources by conventional method is a time consuming and highly expensive process.

In this study a standard methodology is proposed to determine groundwater potential using integration of RS & GIS technique. The composite map is generated using GIS tools. The accurate information to obtain the parameters that can be considered for identifying the groundwater potential zone such as geology, slope, drainage density, geomorphic units and lineament density are generated using the satellite data and survey of India (SOI) toposheets of scale 1:50000. It is then integrated with weighted overlay in ArcGIS.

Water is one of the most essential commodities for mankind and the largest available source of fresh water lays underground. Tremendous increase in the agricultural, industrial and domestic activities in recent years has increased the demand for good quality water to meet the growing needs. Groundwater is mostly preferred to meet this growing demand because of its lower level of contamination and wider distribution. The occurrence of groundwater is a consequence of the interaction of the climatic, geological, hydrological and physiographical factors.

Maps have long been identified as a political document aimed at structuring human senses, expectations, desire and notion on the space around. Developments in Geographic information technology which combines GIS, Remote Sensing and GPS has created new avenues in mapping and spatial decision making. Advent of FOSSGIS and Web GIS has further simplified data availability and analytical capability. These new technological advances have helped the use of critical mapping which is a set of new mapping practices and theoretical critique grounded in critical theory.

Agricultural production monitoring through remote sensing and GIS can support decisionmaking and prioritization efforts towards sustainable vulnerable parts of agricultural systems. Crop mapping process is the one of these applications since remote sensing provides us precise, up-to-date and cost-effective information about the land use and cropping pattern along with different temporal and spatial resolution. In this study, spatial crop mapping was done using satellite Landsat 8 data for Hoshangabad district, Madhya Pradesh.
