Watershed Mapping

ARSGS has also involved in rural sector projects like “Impact assessment and monitoring of watersheds” using Remote sensing and GIS techniques and created geodatabase for NABARD .

  • The application of RS & GIS in our country have been shown tremendous progress and have established the potential of this technology for natural resources ( soil, water etc. ) management and environmental monitoring in various sectors.
  • High spatial and temporal resolution satellite data could be effectively used for watershed management and monitoring activities at land ownership level.
  • These techniques are also successfully used for preparing detailed thematic maps, watershed development plans and continuous monitoring of the natural resources in watershed areas.
  • Though conventional methods (surveying) provide information, but they are slow, rough data, time consuming and expensive. Among the new technologies emerged for studying natural resources, space borne RS technology proved to be powerful.
  • Synoptic view of the terrain features with the high spatial, spectral and temporal resolution satellite data.
  • The GIS application provides an ideal environment for integration of data and helps in generation of action plan for development of watersheds. After implementation of action plan, multi-temporal satellite data help in monitoring its success and progress.
  • High spatial resolution panchromatic and multispectral data may further enhance our capability of generating farm-level action plan for land and water resources development, and to study the success and progress of the implementation of such action plans.
