Local coordinates (Cartography 🗺️)

Local coordinates are the ones used in a local coordinate system or a local coordinate space. Simple examples: Houses. In order to work in a house construction, the measurements are referred to a control arbitrary point that will allow to check it: stick/sticks on the ground, steel bar, nails... Addresses. Using house numbers to lo...

The Armed Forces of #Ukraine switch to the WGS-84 world coordinate system, commonly used by #NATO countries, instead of the Soviet SK-42, which is accurate only for the territory of the former #USSR.
Establishing #coordinatesystems of the Alliance will improve the compatibility of troops and ensure the exchange of data between the Ukrainian army and other states. With the transition to #WGS-84 maps will become more accurate since SK-42 was based on a different mathematical model of the #Earth.
