The urban growth of recent decades has created a significant imbalance betweenthe environment, the territory and its inhabitants. This process therefore results inenvironmental issues such as pollution, overcrowding, excessive accumulation ofdebris and flooding of urbanized areas, among others. In this paper, theenvironment and the perception of the people (through surveys), are unmeasuredand located in the territory, in order to recognize common ground between thethree and to identify areas of urban-environmental vulnerability (AU-AV).It explains a technical-instrumental system, developed from a relationalmethodology of information, forming a body of data with which to identify theissues raised. In this case, the analysis information, allowed discrimination:(i) the geographical location of the perception of the people; (ii) the degree ofinfluence of territorial and environmental variables; (iii) identification of areaswhich are affected by this influence. Recalling that, given the complexity ofcollision, we must work from methodological triangulation, where informationmust respond to quantitative and qualitative methods whose implementation canbe independent or combined.The Inverse Distance Weight (IDW) interpolation method was used,pertaining to the program Arc Gis 9.3. This method incorporates the informationof each survey territorialized (as information points) and calculates the value ofits attribute depending on the information of the surrounding points, which allowfor obtaining graphical results (maps). The maps have been a key figure input toidentifying these areas. Variables submitted for appraisal of the perception ofpeople, allowed us to obtain and identify certain detailed issues as intrinsicdirectionality between the response and the observed and causal territorialisationof them.
