ISOCHRONE
The term ISOCHRONE (from the Greek equal time) in the cartographic sector refers, given a starting point and a time, to the polygon that represents the road area reached from the starting point in the indicated time
ISODISTANCE
The term ISODISTANCE (equal distance) in the cartographic sector refers, given a starting point and a distance, to the polygon which represents the road area reached from the starting point by traveling the indicated distance
STREET NETWORK
In our system, in addition to providing a polygon, for the isochrones/isodistances, we can also provide the underlying road network divided by time/distance ranges
CATCHMENT AREA
The polygon created by an isochrone/isodistance can be used for the calculation of the contained population, incomes or other data if available
