Abstract—Imaging systems, particularly those on board
satellites, provide a repetitive and consistent view of the earth
that has been used in many remote sensing applications such as
urban growth, deforestation and crop monitoring, weather
prediction, land use mapping, land cover mapping and so on. For
each application it is necessary to develop a specific methodology
to extract information from the image data. To develop a
methodology it is necessary to identify a procedure based on
image processing techniques that is more adequate to the
problem solution. In spite of the application complexity, some
basic techniques are common in most of the remote sensing
applications named as image registration, image fusion, image
segmentation and classification. Hence, this paper aims to
present an overview about the use of image processing techniques
to solve a general problem on remote sensing application. A case
study on an urban application is provided to illustrate the use of
remote sensing technologies for solving the problem.
