162 NESPAK PROFILE 1973 - 2018 GEOGRAPHICAL INFORMATION SYSTEM SECTOR

The Geographical Information System (GIS) SCOPE OF SERVICES is a framework to collect, store, manage, manipulate, analyse and visualise spatial Real-time Crop Water Monitoring using data. GIS enables to store information in Satellites: Identification of crop types, layers and retrieve data to identify unique development of Normalised Difference patterns, solve complex problems, Vegetation Indexes (NDVIs), generation of automate processes and build decision NDVI time-series using Fourier components support systems. (magnitude and phase), calculation of evapotranspiration and calculation of crop The GIS has the potential to be used in water requirements. virtually every field. The application of GIS includes urban planning, transportation DSM and DTM Generation from Drone planning, environmental risk analysis, Imaging: Production of extremely high- climate change, flood forecasting and resolution Ortho-mosaics (less than 10cm), damage estimation, disaster management Digital Surface Models (DSM) and Digital and mitigation, emergency response, hydro- Terrain Models (DTM) from Unmanned informatics, irrigation water management, Aerial Vehicle (UAV) or Drone imaging.

Mohmand Dam Iran-Pakistan Gas Hydropower Pipeline Project Project NESPAK conducted flood inundation studies of Swat and Kabul Rivers with historical data of 2010 super-flood during detailed design study of Hydropower Project. The flood inundation was computed for both the rivers up to Nowshera Bridge. Quantification of inundated area was also carried out for damage estimation.

Under Iran-Pakistan Gas Pipeline Project, GIS database has been developed for land use environmental, hydrological and route constraints marked on 5km wide route corridor with detailed topographical survey of 200m finalised route corridor. A web GIS application on ESRI ArcGIS Server has also been developed to disseminate spatial information to the project stakeholders through a virtual private network.

Under this project, CREEC entrusted DGPS-based establishment of (Horizontal and vertical) Geodetic Control along 1800 km long Main Line (ML-I) to NESPAK. NESPAK conducted the fourth order horizontal control and first order vertical control network establishment along the Main Line (ML-I) referenced with the Survey of Pakistan.

Geohazard mapping and preparation of geohazard inventory of Diamer Basha Dam reservoir was conducted during the World Bank-funded Environmental and Social Impact Studies for the Diamer-Basha Dam. NESPAK carried out Landslide Susceptibility Mapping study for the Diamer-Basha Dam reservoir, using the Bivariate Statistical Weight of Evidence Method (WofE) Method. Reservoir area was categorised in three classes i.e., high hazard, moderate hazard and low-to-no hazard.
