As you can imagine, not much in the way of geographic analysis could happen using these methods. GIS was a game changer because it allowed us to effortlessly switch between coordinate systems and combine data and maps that were previously incompatible. We refer to these switching methods asproje...

2、em). The geographic coordinate system is the coordinate system based on latitude and longitude, and there are 2 important parts in the geographical coordinate system, namely, the earth ellipsoid (spheroid) and the earth datum (datum). Due to the irregular surface of the earth, it can not...
Proj.4 is a C/C++ library that allows a user to project geographic coordinates to a cartographic (planar) coordinate system and to transform data between different coordinate systems and datums. Proj.4 is used by many projects and therefore can be considered a FOSS4G core library. Recently the...
At ArcGIS Pro 3.0, the following changes have been made to coordinate systems, map projections, and geographic transformations. Several planetary satellites and extraterrestrial bodies had updated definitions added based on the IAU/IAG 2015 publication. Projected coordinate systems for Mars and t...
Coordinate System such as GCS_WGS_1984, the North Pole and South Pole, which are points, are displayed as lines at the top and bottom of the data, and these lines are as long as the Equator. This graphically demonstrates the distortion that exists using a Geographic Coordinate System for ...
the line is totally different from the original and not positioned where I drawed it. I know it's a projection problem, I've tried trasforming the geometry object from Mercator to Geographic, also getting directly the geographic coordinates from the map coordinates, but nothing. I tried to s...

A map view operates with three different coordinate systems: The geographic coordinates The projected plane on which the geographic coordinates are projected, and The pixel positions within the plot area, onto which the projected plane is scaled and translated. ...
The world is divided into small squares, each with a fixed geographic area and scale. This clever trick allows you to browse just a small part of the planet without loading the whole map - and you still get an illusion of exploring a single huge document.Spherical Mercator Pioneered by Goog...
