The expansion of cities in Mexico is on the agenda of government agencies in charge of territorial policy, which see in the compact city model the solution to horizontal overflow and disorderly growth. The objective is to construct a methodology that allows to identify the types of urban voids by their dimensions and locational context. The need to have an inventory of vacant intra-urban space is the first step in guiding population containment and concentration efforts; and as a result, a proposal is suggested with five categories, of which, in the main cities of Mexico, 55% of the vacant intra-urban land represents. This work was carried out with the use of geospatial technology (Geographic Information Systems and Remote Sensing), from which a methodology was designed to identify, from 11 stages, the type of vacant intraurban land classified. Photointerpretation and photoidentification were used on high resolution spatial satellite images of 60 centimeters in pixel size to digitize the area of each urban void; and, the spaces of difficult identification with remote perception (Dron Phantom 3 and 4 pro) were validated to reduce the error and facilitate the categorization established. The methodology starts from designing a typology with five empty spaces inside the cities that privileges its location, size and context; Later, to identify each category, 11 stages are suggested, ranging from conceptual definition to spatial analysis to determine concentration patterns. It was found that of the five categories, 55% of the urban voids are concentrated in the type Batch Lots.
