ABSTRACT

Making decisions based on geography is basic to human thinking. By understanding geography and people’s relationship to location, we can make informed decisions about the way we live on our planet. A geographic information system (GIS) is a technological tool for comprehending geography and making intelligent decisions.

GIS organizes geographic data so that a person reading a map can select data necessary for a specific project or task. A thematic map has a table of contents that allows the reader to add layers of information to a base-map of real-world locations. .

GIS maps are interactive. On the computer screen, map users can scan a GIS map in any direction, zoom in or out, and change the nature of the information contained in the map. They can choose whether to see the roads, how many roads to see, and how roads should be depicted. GIS applications can be embedded into common activities such as verifying an address. From routinely performing work-related tasks to scientifically exploring the complexities of our world, GIS gives people the geographic advantage to become more productive, more aware, and more responsive citizens of planet Earth. For any development project, the protection of water resources is extremely important. Construction over the drainage path or watershed can affect the water resources of the region. The establishment and maintenance of buffer zones along shorelines or streams is a common management practice used in ecological and environmental planning. The buffer analysis tool in GIS helps in setting buffer zones for the water bodies.

Environmental planning also addresses risks of natural hazards and disasters. The use of environmental and GIS data to construct a flood hazard map has been done for many projects.

IRS P-6 LISS III imagery of Mahesh River Basin reveals the presence of prominent lineament sets. Lineaments have been recognized with the advent of satellite imagery. It has been convincingly demonstrated that many of these structures are related to basement tectonics. There it has been shown that structural anomalies the definition of enhanced fracture production zones over Deccan trap are commonly coincident with pervasive basement lineament trends. For instance, the satellite imagery data interpretations supports the view that Gavilgarh faults indicates an older age and the remaining lineaments represents a younger age. The basin lies between two major lineaments i.e. Purna lineament following the course of Purna River display a WNW-ESE trend it is traceable for over 80 km from south of Akola in the east to some distance east of Jalgaon in the west, where it merges into Tapi lineament, this lineament lies in the northern part of the basin and the southern part is delineated by Kaddam lineament trending NW-SE and extends up to 240 km and that has been named after Kaddam River whose course has been controlled by this fault lineament. This lineament has northerly dipped. Faulting has been recognized in several sectors of this lineament. The basin lies between two major lineaments i.e. Purna lineament following the course of Purna River display.
