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. It can automatically archi

DIPS

 Download    Download  Download . DIPS is a stereographic projection software used primarily in geotechnical engineering and geosciences for the analysis and presentation of orientation-based data. It is widely used to interpret and visualize structural data, such as joints, faults, and bedding planes, in rock formations. It is developed by Rocscience . Key features of DIPS include: Stereographic Projections : The software allows users to plot geological data on stereonets for detailed structural analysis. Orientation Analysis : It facilitates the analysis and presentation of orientation-based data such as the dip and strike of planes and the trends and plunges of lineations. Visualization Tools : DIPS provides visualization of vectors, density contours, plane intersections, and traverses, making it easier to interpret geological structures. Geotechnical Applications : It's particularly useful in projects involving slope stability, tunnel design, rock mechanics, and any engineerin
