ALX uses GIS (Geographic Information System) data provided by OpenStreetMap. 

The GIS map displays the elements of the supply chain scenario and their connections. Once you create a new element (e.g. a customer) or alter an existing connection, the GIS map will be instantly updated.

Map view displays and manages the map projection. In geospatial terms, a projection is the translation between a spherical model of the earth to a flat, two-dimensional surface. In OpenStreetMap, projections are components that handle the translations between latitude and longitude coordinates and screen locations. Cartesian coordinate systems are not easily handled in OpenMap. OpenMap projections only handle translation from decimal degree latitude/longitude data to map view x/y coordinates.

A datum is a definition of how coordinates on the sphere are defined. OpenMap projections assume that latitude and longitude coordinates are defined in terms of the WGS 84 datum. OpenMap projections are based on a spherical model of the Earth. Ellipsoidal flattening (eccentricity) is not taken into account.

Tiles displayed by the map will be copied to the project folder. In case you copy your project elsewhere all files will be copied as well.
