Google Maps and Google Earth are very common platforms today to explore maps and satellite images of the earth. But there are many other ways to explore the earth. Some are listed here. 1. Earth Explorer This map is developed by USGS helpful to obtain earth imagery across available geo-spatial data types. Users can navigate via interactive map or text search to obtain Landsat satellite imagery, Radar data, UAS data, digital line graphs, digital elevation model data, aerial photos, Sentinel satellite data, some commercial satellite imagery including IKONOS and OrbView3, land cover data, digital map data from the National Map, and many other datasets. Users can search by exact location via the interactive map or input specific coordinates to view what data types are available. 2. Sentinel Hub This platform developed by Sinergise has Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysi...
Initial surveys along widely spaced profile lines covering large areas for regional geology and enable plan of detail follow up survey.
Detail reflection survey in areas of interest/prospective targets found from initial stage.It involves closely spaced profile lines and high density of profile intersection to define useful structures. Initial interpretation involves structural mapping to identify structural closures and the identified closures need a second round of detail survey to select location of exploration borehole. 3D survey may be used if unsoed by 2D data.
Exploration boreholes are sited on seismic lines sp borehole logs can be correlated directly with local seismic stations.
Refinement of seismic data from additional seismic profiles. Seismic modelling can be used to obtain detailed information on geometry of reservoir and internal lithological variation that may affect HC yield. 4D surveys can detect unexploited arrears in a producing field.
