More about coordinate systems on Aino

EPSG4326

This refers to the World Geodetic System 1984 (WGS 84), which is a standard for representing locations on the Earth's surface. EPSG4326 specifically denotes a geographic coordinate system using latitude and longitude coordinates, where the Earth is modeled as a sphere. The EPSG code 4326 is commonly used in GIS software to represent locations in a global context.

EPSG3857

This corresponds to the Web Mercator projection, also based on the WGS 84 datum. Web Mercator is a cylindrical projection commonly used in web mapping applications like Google Maps and OpenStreetMap. It's favored for its ability to display maps on flat computer screens with minimal distortion, making it suitable for interactive online maps. EPSG3857 specifies the coordinate reference system (CRS) for this projection.

EPSG32638 (beta)

This represents the Universal Transverse Mercator (UTM) projection for zone 38N, using the WGS 84 datum. UTM divides the Earth into a series of longitudinal zones, each 6 degrees wide, and employs a transverse Mercator projection within each zone. Zone 38N covers a portion of the Earth's surface roughly between 42°N and 48°N latitude, and it's commonly used for mapping and navigation within that region. EPSG32638 defines the CRS for this specific UTM zone.
