This is a problem if he intends to project this map with another in a multi-layer database. In this study we used the coordinates of selected ground control points (GCPs) obtained with a Trimble GPS unit to transform (georefrencing) the network base map (1:10000-scale; unknown coordinate system) digitized in units of the base map into metric UTM system. Registration was done using affine transformation in ARC/INFO GIS. The accuracy of this procedure was analyzed by comparing the GPS positions of 40.72 km one-way-roads with their corresponding GIS transformed positions. A 40-m buffer was required for at least 96% of the GIS roads to occupy the same GPS road positions. The georefrenced network map was successfully updated by map-to-map registration involved a residential area map developed from recent SPOT image and a soil salinity map developed using variogram ...

Moreover, the aim of remote sensing can be extended to monitor and record and changes that might occur to these resources, either because of human activities or natural processes. This study aims to use remotely sensed data to study the state of vegetation cover in Al-Hassa oasis during the past ten years and to assess the impact of the environmental changes resulted from the operation of the irrigation and Drainage Project.

Thus, several indices for vegetation and soil salinity have been developed. This study was conducted to assess the soil salinity levels in the Al-Hassa Oasis, which is dominated by date palm vegetation, in the eastern province of Saudi Arabia. Ground and remote sensing data were used to determine if any existing vegetation and soil salinity indices could be used to assess the soil salinity of communities vegetated with date palm. A systematic regular grid-sampling approach was used to collect a total of 149 composite soil samples from the study area. Thirteen broadband indices, which encompassed vegetation and soil salinity indices, were extracted from IKONOS satellite images. The predictive power of these indices for soil salinity was examined. The study area was dominated by areas of high salinity. Among the investigated indices, the Soil-Adjusted Vegetation Index (SAVI), Normalized Differential Salinity Index (NDSI) and Salinity Index (SI-T) yielded the best results for assessing the soil salinity of cultivated lands with dense and uniform vegetation. In contrast, the NDSI and SI-T exhibited the highest significant correlation with salinity for less densely vegetated lands and bare soils. Generally, the soil salinity in the areas that were dominated by date palms was successfully assessed by broadband vegetation and soil salinity indices that were extracted from the IKONOS satellite images.

The water provided by municipality is not suitable directly for drinking, because of its high content of total dissolved solids. Most people at Al Hassa are using the purified water from private purification stations, as bottled water is affordable only to the rich. There are 45 purification stations at Al Hassa region, all of which used Reverse Osmosis (RO) techniques for water purifications. The aim of this paper is to establish a decision support system based on Geographic Information System (GIS) called, drinking water spatial decision support system (DWSDSS) to manage the available data for the private purification stations (location, water source, purification equipments, etc.). Moreover, this system will provide full details about the quality and the quantity of the produced drinking water from these stations. Nowadays, the use of GIS...

The water of this lake is originated from the excess of drainage water which collected by earthen drainage network and discharged into the lake. Wetlands are important link between water and land ecosystems. They provide habitats and refuges for wildlife, flood protection and contribute to abatement of impact of pollution and promoting groundwater recharge. The main morphologic features of Al Uyoun Lake area are wetlands, sabkhas and sand dunes. Salt tolerant vegetation (halophyte) is found in some of the less salt affected sabkha areas. The present paper aims to study the environment of Al Uyoun Lake through integration of remote sensing and geographical information systems (GIS) coupled with Sedimentological, hydrogeological and chemical investigations. A complementary objective of this study was to demonstrate the GIS capabilities in exploring the full value of environmental data...

In this respect, seventy five representative samples of soil have been collected from different localities of Al Hassa area and its surroundings. The activity concentrations of radionuclides in each soil samples have been measured. The concentrations for 234 U and 238 U series together with that of total uranium in parts per billion (ppb) are measured . The result of this study reveals that the activity concentrations for uranium series (progeny) in the soil samples are much higher than the same series in the ground water samples at Al Hassa area. In the soil samples, the activity concentrations obtained for 238 U and 234 U ranged from 113.45 to 437.45 pCi/Kg, and 174.21 to 415.55 Picocurie /Kilogram (pCi/kg) respectively.
