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...
Channel Flow:
- focuses on the ductile flow of weak mid-lower crust driven by pressure gradients and facilitated by heat
- development of the Greater Himalayan Sequence as a consequence of the extrusion of a weak mid-crustal channel at the surface
- Channel flow develops in the thickened orogenic crust due to ductile weakening caused by thermal relaxation and radioactive heating and driven outward from beneath the orogen by the pressure difference between the plateau and the foreland
- the channel is interpreted to have been uplifted and exhumed to the surface by climate-enhanced erosion focused on the flank of the plateau
- Exhumation occurs between coeval basal thrust-sense and overlying normal-sense shear zones
Critical Wedge Model
- himalaya is evolved as wedge
- critical wedge model focuses on the brittle, upper-crustal behavior driven by friction and taper,
