Copernicus Sentinel vs GeoCanvas

The Sentinel App is a gateway to knowing the Copernicus Sentinel satellites. It lets users track the satellites in real-time, discover their key elements, read the latest news and learn more about their products. Users can, among other things, explore detailed 3D models of the satellites, see the last and next time they have been and will be over the user's location, move the satellites to the time of the last data transmission and smoothly move them back to their current location over the 3D globe. Notifications can also be set to be warned when the satellites are flying by. ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative Copernicus (previously GMES - Global Monitoring for Environment and Security). The goal of the program is to replace current and older Earth observation missions, such as ERS and Envisat, which have reached or are close to reaching the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies. Each mission will focus on a different aspect of Earth observation, such as Atmospheric, Oceanic or Land monitoring, and the data will be of use in many applications.

Every flat map of a round world distorts something: area, shape, distance or direction. You cannot avoid it, only choose what to give up. GeoCanvas lets you watch that choice being made. Switch between 55 projections, turn the globe, and see exactly what each one gives away. EXPLORE • The familiar: Mercator, Robinson, Winkel Tripel, Equal Earth, Mollweide, Natural Earth, Albers • The rarely rendered: Waterman butterfly, Peirce Quincuncial, Airocean, Berghaus star, tetrahedral Lee, interrupted Mollweide • Cylindrical, pseudocylindrical, azimuthal, conic, polyhedral and interrupted families, side by side • Rotate and re-centre a projection, and watch the distortion follow the viewpoint • Search any place, or jump to where you are with My location BUILD • Vector, raster and terrain layers, as many as you like on one map • Colour a layer by category or by value in a few taps, with ready-made colour ramps • Draw on the map directly with parametric tools • Symbology, labels and legends • Isolines and relief shading IMPORT • Bring your own GeoJSON or zipped Shapefile • The coordinate system is read from the .prj and converted for you, with an honest note on how exact the conversion is EXPORT • PNG, JPEG, TIFF, SVG and GeoJSON • Print sizes up to A3 at 300 dpi, or set your own dimensions • CMYK separation for press work, from a measured profile rather than a guess • Leave the geocanvas.app wordmark off: only the data credits stay WHO IT IS FOR Geography teachers explaining why Greenland is not the size of Africa. Cartographers prototyping a layout. Students, journalists, designers, and anyone who has looked at a world map and felt something was off. One purchase, no ads. Optional: an auto-renewable monthly AI subscription for more and longer conversations with the map assistant. GeoCanvas runs on open data, including Natural Earth.
