Explore the Earth, Maps and Satellite Images

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 analysis.

Mineral Resources in Nepal

  The prospect of Mineral resource in Nepal is mainly controlled by Geology of Nepal . Based on the tectonic divisions of Nepal, the potential for mineral resources is as follows: ·        Terai Plain (Indo Gangetic plain) area is potential for gravel, sand, ground water, and underlying petroleum and natural gas bearing Siwalik and Pre-Siwalik rocks. ·        The Sub Himalaya (Siwalik/ Churia Range including Dune Valleys) is the potential area for construction materials, radioactive minerals, petroleum, natural gas and minor amount of low grade coal. ·        The Lesser Himalaya (Mahabharat Range including Midland/ Valleys) is promising for metallic minerals mainly iron, copper, lead, zinc, cobalt, nickel, tin, tungsten, molybdenum, gold, uranium rare metals, industrial minerals like magnesite, limestone, dolomite, talc, phosphorite, bauxite, clay, kaolin, graphite, mica, quartz, silica sand and gemstones; fuel minerals such as coal, methane gas, petroleum and natural gas;
