Utility Mapping

Netxcell has completed Electric asset mapping for several towns in our country, right from DGPS survey to geo-database creation under RAPDRP Project. The methodology adopted for this project:

  • Processing of satellite imagery & geo-referencing of a project area.
  • Creation of satellite imagery base map of a project area.
  • DGPS survey and mapping of each network entity and landmark.
  • Creation of digital network map of a project area.

    Watershed Mapping

    Netxcell has also involved in rural sector projects like “Impact assessment and monitoring of watersheds” using Remote sensing and GIS techniques and created geo-database 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 the 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, they are slow, rough data, time consuming and expensive. Among the new technologies emerged for studying natural resources, spaceborne RS technology proved to be powerful.
    • A synoptic view of the terrain features with the high spatial, spectral and temporal resolution satellite data.
    • The GIS application provides an ideal environment for the integration of data and helps in generation of an action plan for the development of watersheds. After implementation of the 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 a farm-level action plan for land and water resources development, and to study the success and progress of the implementation of such action plans.
