The article deals with the structuring of georeferenced geotechnical information database and the elaboration of a preliminary foundation letter that reflects the north-central region of the city of Fortaleza. Using the Google Earth software, 395 drill holes were collected percussion at local companies and outlined 23 regions, from the statistical treatment, maps of NSPT isovalors were plotted at depths of 2, 5 and 10 m, at water level the representative survey. After establishing three lots of buildings, a preliminary list of foundations was drawn up. It is concluded that the system used in the georeferencing of the collected data is adequate, has an easy handling and uses small files. Considering small buildings, almost always, it is possible to use foundations of the type shoe based to small depths. Medium and large buildings it is estimated, preliminarily, lengths varying with positioning of the region.
