The problem of excessive soil sealing and the consequent macro-microclimate degradation process need specific measures.

The use of standards and indexes finalized to the regulation of the soil permeability permits flexible and resilient solutions that allow environment to find a new balance.

The application of the Biotope Area Factor (BAF), as index focused on the integration of urban planning and ecology, is a tool with a dual function: it allows to address a structural choice giving more space to planning and to get better consolidated areas.

The main scope of the paper is presenting a way to calculate BAF which is automatic and based on existing digital cartography and GIS technology.

First authors present a description of the general problem; then they focus on the BAF index as urban parameter computable from direct analysis and web images. The classical way to manually measure BAF is presented with application to the city of Pavia.

Then authors introduce the automatic GIS-based procedure starting from a description of the specification of the Lombardy Region cartography and illustrate all the steps and issues of the developed procedure.

Finally authors rigorously assess the developed procedure by means of manually surveyed test areas and discuss results and further steps of the research.
