The fusion of satellite images is performed using the<br>fast haar wavelet transform (FHWT) that was implemented in Matlab.<br>The article is organized around of two themes important: the Web<br>service and the fusion of images. With regard to the development and<br>implementation on the Web, this is done in free software with tools<br>such as MapServer, Apache, Drupal. These tools were used to create a<br>simple interface where the user takes part and interacts actively. In the<br>same way that allows that user: displays the information on processes<br>obtained for the fusion of images; and makes a request for fusion of<br>image. In addition, the web implementation develops a module for<br>obtaining georeferenced data from two or more external sources to<br>create a new service. It involves a quick, and easy integration through<br>APIs that offer some tools on the internet as OpenStreetMaps, these<br>basically source data that produces results that were not the original<br>reason for the raw data of the source. An example is the use of data<br>(satellite images) to add location information (location). As for fusion of<br>satellite images, it presents the mathematical algorithm for the fast haar<br>wavelet transform (FHWT). As an alternative to the fusion implemented<br>in Matlab (result of a previous study). The (FHWT) implemented with<br>Matlab, and also using five different wavelets predefined in Matlab.<br>The best results were obtained with the fusion that uses the (FHWT)<br>method implemented in Matlab, so it is used (TRHW) in the Web service<br>to provide the fusion of images.</p> ER -
