The use of geographic information systems (GIS) is wide in diverse and different disciplines; as one of its main attributes, GIS allow the management of geographically referenced information, that is, data with geographical position. This work presents a technique for extracting information from databases and their subsequent geolocation. The technique is illustrated with a case where demand data for transportation services of a higher education Institution in Mexico City are handled considering its geographical position. The technique start with establishing criteria of search, selection and grouping in a data base taking into account what data it is possible to geolocate.
