Integrated geoscience databanks for interactive analysis and visualization

Figures & data

Figure 1. Distributed Geospatial Data Infrastructure consisting of database servers for imagery, binary grids, digitized vector layers and geological and geophysical databanks, linked with integrated visualization and interactive query system along with a set of processing applications and services.

Figure 2. Satellite imagery [Landsat 7, bands 2, 4, and 7, Source: National Aeronautics and Space Administration (NASA)] overlaid with colored contours of topography [30 arc-seconds Shuttle Radar Topography Mission (SRTM30), Source: National Geospatial-Intelligence Agency (NGA) and NASA] and black contours of gravity [Source: Pakistan Geophysical Database]. A sedimentary basin was demarcated with an orange line by identifying the zone of low gravity.

Figure 3. Satellite Imagery [Landsat 7, bands 2, 4, and 7, Source: National Aeronautics and Space Administration (NASA)] with three exploration data layers; lease concessions polygons, seismic lines (yellow lines with purple pickets) and wells (red circles) [Source: Pakistan Exploration Database]. A 3D seismic survey grid was planned in the lower-left area using interactive seismic survey design tools.

Figure 4. Shaded relief map generated from Digital Elevation Model [3 arc-seconds Shuttle Radar Topography Mission (SRTM3), Source: National Geospatial-Intelligence Agency (NGA) and National Aeronautics and Space Administration (NASA)] overlaid with structural faults (pink lines) [Source: Pakistan Geophysical Database], earthquake epicenters (green, blue, and red dots) [Source: National Earthquake Information Center (NEIC), US Geological Survey] and administrative boundaries of Pakistan (yellow). A seismic hazard zones map was generated by analyzing the faults and earthquakes patterns. It highlights four seismic risk zones; minor (green), minor to moderate (blue), moderate (orange) and severe (red).
