Use of Satellite Data and GIS for Soil Mapping and Capability Assessment

Nature and Science of Sleep 01/2010; 8:104-115.


This study aims to use the satellite data and Geographic Information System (GIS) to produce the soil map and use the spatial analysis technique to assess the soil capability. The soils adjacent to El-Manzala Lake east of the Nile Delta, Egypt were chosen for this application. To achieve this objective the land surveying, and satellite
data (Landsat ETM and SRTM images) were used in a Geographic Information System to delineate the landforms of the studied area. The correlation between landforms and soil taxonomic units were worked out. The results indicated that the area was dominated by flood plain (33.48 % of the total area), the lacustrine plain (21.52 % of the total area) and the marine plain (3.13 % of the total area). The Water bodies and urban areas exhibit 41.86 % of the total area. The soil properties such as CaCO3 content, texture class, soil depth, salinity, alkalinity, CEC and drainage condition were linked with the different landforms of the studied area. The thematic layers of these data were created in Arc-GIS 9.2 software using the spatial analysis function, and then these layers were matched together to assess the soil capability. The data obtained from the thematic layers indicate that the main limiting factors in the studied area were soil depth, drainage conditions, soil salinity, soil texture, alkalinity and calcium carbonate content. The limiting factors; CaCO3 %, soil depth, drainage condition, salinity and alkalinity were associated with the lacusrtine plain, while the soil texture and CEC were the main limiting factors in the marine plain. The soil depth, drainage condition and soil salinity were the dominating limiting factors of the flood plain.

Ordinary method for mappingthe topsoil properties is to collect samples using a grid sampling system, then; a prediction map can be made by interpolating the measured property values of the samples (Karydas et al., 2009).
