Some history

The history of gisEIEL begins as far in time as in 1986. That year, the first edition of EIEL database of A Coruña Province was launched.

EIEL is an achronym that stands for the Spanish of Enquiry on Local Infrastructures and Services. It consists of a huge database containing information on all of the public facilities, services, premises, etc at the municipal level, be them publicly owned and managed or not, but publicly usable, anyway.

Data are collected at settlement level, so that it is known what infrastructures or services are available at every settlement within a given municipality. In A Coruña province, as well as in the rest of Galicia, this is not a trivial issue as here there are over 4.000 queriable settlements , with more than 11.000 populated areas in total in an area of 7.900 Km sq.

So, managing those data by means of using GIS technologies is, clearly, the most adequate solution.

First somehow useful application used to manage EIEL data was launched during 1995. It produced coropleth maps of the province that showed the degree of implementation of different services at each municipality.

The first actual and complete migration of EIEL data to GIS environment was held during Phase IV updating, when all of the data capture and digitization tasks were undertaken by means of ad-hoc built GIS applications.
