Abstract

The maps are constantly outdated due to natural changes that occur in the environment over the years and caused directly by man. Remote Sensing Images have long been used to support the area of cartography. These images are used as techniques of Digital Image Processing (DIP) that involve the manipulation and interpretation of digital images. Among the various tools PDI has to Mathematical Morphology for the extraction of cartographic features, developed initially by Matheron (1975) and Serra (1982). The aim of Mathematical Morphology is quantitatively describe the geometric structures and function as a technique in the design of algorithms in the area of PDI, offering basic tools such as edge detectors and morphological filters. Currently, Mathematical Morphology is a theory widely used and researched in Universities and Research Centers around the world, being an excellent base to study the geometry of the signal, it allows to quantify size and shape. Thus, this project aims to continue the proposition of integrated methodologies for extraction and / or detection and treatment of cartographic features using mainly techniques of Mathematical Morphology. The result of extraction and / or detection will be subjected to quality control to verify the accuracy and precision obtained by applying the proposed method and to demonstrate the potential use in the field of cartography. Will use digital images of terrestrial and Martian surfaces. The ongoing research by the new project will enable the validation of the methodology proposed in a previous project and will facilitate the publication of articles in refereed journals, especially internationally, since the results obtained to date indicate the potential use of the proposed methodology in the field of cartography and related fields. These results are being published and widely disseminated. (AU)
