Remote sensing technique is considered as one of the main sciences that grew very
fast last years. Satellite images are important and advanced source to get data about any
region on the earth. Using satellite images, integrated with geographic info
rmation system
(GIS) for mapping are considered as one of the modern applications that expanded widely
now a days.
This paper aims at integrating the techniques of remote sensing and geographic
information systems (GIS) for performing topographic study of landsat7 satellite image
taken of a part of northern part of Lattakia. The two software, Erdas Imagine and ArcGIS
are used to perform topographic analysis depending on digital processing for the image,
then analyzing its terrain. Depending on digital terrain model (DTM), 3D slope image is
derived. Land use map is written for the study area. Then, some spatial analysis are
performed to find the best positions to construct different projects that have economic
benefits.
finally, analyses and results are discussed.
