This study concentrates the use of remote sensing and geographic information systems to identify prospective areas for water harvesting, This study concentrates on the identification of the potential areas for water harvesting projects in Hessia and the adjacent areas, within a total area of 1300 km2. The data and information for the study area are collected from different sources and satellite images. The thematic maps and digital database were prepared through analysis and visual and automatic interpretation of satellite images, and analysis and intersections between different layers were procedure in order to apply the criteria that are used in these studies to determine optimal and typical sites for the establishment of preparation water harvesting. The result of this study shows the efficiency of using the remote sensing techniques and the geographic information system in the identification of the potential areas for water harvesting projects.

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.
This study aimed to describe the water erosion modeling in Daher Aljabal
and its surrounding areas in Al-Sowaida Governorate based on GIA and RS.
The water erosion risk map was obtained by applying GIS model developed on
the basis of ten factors i
nfluencing the erosion process. GIS layers were built
for every factor. The weights for all factors were added together. Based on sum
of these factors, water erosion was divided into six erosion risk levels. Results
showed that 12% of the study area was classified in levels 5 and 6, which reflect
high and very high water erosion risks. Land topography was the main factor
in water soil erosion. Terraces are effective ways to decrease the water soil
erodability. Results also showed that GIS and RS were powerful tools in water
erosion risk assessment mapping.
The aim of this research is to study and prognosis oil and gas by utilization of Remote Sensing (RS) data Geographic Information
System (GIS) and Digital Elevation Model (DEM), and 3D. The integration of the data by using program (Arc GIS). The inte
gration data led to divide the lineaments circular structures and drainage network. Which present direct and indirection indicate on earth surface for surface and subsurface structures Which play important role in prospecting oil and gas.
Al- Qusier region is important agricultural areas in Syria, and
contribute to cover a significant part of the agricultural needs of the country ,but it was suffering of poor land use in some locations.
This study aims to prepare maps of land use an
d land cover using
remote sensing and geographic information systems (GIS)
techniques, the study relied on SPOT-4 satellite images with spatial resolutions 10 m for (white–black) images and 20 m for color images.
The study found a view of results were the ability of remote sensing and geographic information systems in the production of accurate maps of land use/land cover and establish a digital database for spatial land use and land cover for Al- Qusier region.
This study includes a full analysis of climatic, vegetation, and topographical factors in Nabe Matta preserve (Drekish Region – Tartous Governorate – Syria), which is considered as the most important factors affecting forest fires. The data were coll
ected for each fire and analyzed by statistical programs (SPSS) and (EXCEL), and the relationship between these multiple factors and the phenomenon of recurrence of fire in one area (fire risk region) was studied. Then the data and the results of the analysis and multi relationship had been studied within the geographic information system software (GIS) to obtain the map of fire risk region, as well as results from topographic maps (1:50.000), aerial photographs (1:25.000), and the needed maps were designed for the study such as (slope map - aspect map - vegetation cover map - infrastructure map - fire risk region map),then places of monitoring towers and centers of rapid intervention in high-risk areas have been proposed for the occurrence of fires. These maps are considered as warning systems and with it we can predict the probability of any fire in the Preserve when the appropriate conditions are provided for it.
