THE POTENTIALS OF SATELLITE IMAGES FOR MAP UPDATING WITH EMPHASIZES ON EGYPT SAT-1 IMAGES

Using of High Resolution Satellite Images for Updating Large Scale Mapping in Egypt

High and accelerating rate of the urban changes and extensions, in developing countries such as Egypt, calls for an efficient and fast technique for mapping. The availability of the new generation commercial one-meter resolution satellite images has opened a new era for producing and updating large-scale digital maps. The main objective of this study is to evaluate the potential of VHR satellit...

Multi Resolution Fuzzy Segmentation of Satellite Images

Urban Digital Map Updating From Satellite High Resolution Images Using GIS Data

In this paper, we propose two methods aiming at updating Geographic Information System (GIS) urban maps using satellite high-resolution remote sensed images. Both methods are based on the input of a priori knowledge provided by GIS data, and a Digital Surface Model (DSM). This article introduces theoretical aspects of our methods; implementation is currently ongoing.

Oil spill detection using in Sentinel-1 satellite images based on Deep learning concepts

Awareness of the marine area is very important for crisis management in the event of an accident. Oil spills are one of the main threats to the marine and coastal environments and seriously affect the marine ecosystem and cause political and environmental concerns because it seriously affects the fragile marine and coastal ecosystem. The rate of discharge of pollutants and its related effects o...

Automatic GIS Updating from High Resolution Satellite Images

Among all the issues involved in Geographic Information Science, automating the update of 2D building databases is a crucial and challenging issue. Such an update usually starts out with a manual change detection process. The main goal of this paper is to present a new method to automate the detection of changes in a 2D building database, starting from satellite images. The workflow of our appr...
