The territorial planning managers facing the problem of to handle a great amount of space information that it allows them to fulfill his work in opportune and satisfactory form. The present investigation raises a methodology based on the integration of Geomatic and Techniques of Multicriteria Evaluation to obtain a welcome capacity model that facilitates the location of adapted sites to lodge a sanitary filling. The zone of study corresponds to the Communes of Longaví, Retiro and Parral, located in VII Region of Maule - Chile. A vectorial digital data base was constructed, including: road network, hydrography, contours, ground slopes, directions, classes and permeability, vegetation cover, urban establishments, among others. Only 1,86% of the analyzed surface includes zones of "very high" and "high" capacity, 2,61% represents zones of "medium" capacity, and 95,53% of the modeled surface includes classifications of "loss", "very low" and "excluding", being left in evidence the reduced percentage of apt surface to select suitables sites. The developed methodology can be used as a tool of support to taking decision in the processes of territorial planning, limiting the surface on which more intensive studies are due to make, being able to be talked back in other places and to be enriched through the inclusion of new criteria and variables that adjust better to the studied reality. The program counted on financing of the Regional Development National Fund (FNDR) VII Region.
