Automatic stratification of priority areas for Dengue control using the QGIS Model Builder in multicriteria analysis.

Objective: to present a methodological sequence resulting from multicriteria analysis indicating areas with different Aedes aegypti intervention priorities.

Methods: a Female Aedes Displacement Index (IDFAedes) was created, consolidated according to urban blocks, representing interaction between population densities, Aedes aegypti oviposition sites and dengue case notifications; a graphical model (Model Builder) was developed with QGIS software using the Kernel mapping algorithm and IDFAedes as the weighting factor.

Results: stratification for the evaluated example - Anápolis, GO, Brazil - indicated intervention priority levels for urban blocks - 17.
