Rp-The Spatial Changes of Land Uses in Al Museyab City by the Remote Sensing.pdf

Abstract:
The study tackled ” The Spatial Changes of Land Uses in Al Museyab city ” . It relied on remote sensing deducting land uses and representing it by maps during the study period ( 1986-2022) that extends for thirty six years.
Data of the thematic mapper ( TM, OLI) of the American satellite (landsat) were used including the space images for the years ( 1986- 2004-2022). The study depended on the program ( Arc Gis 10,7) to extract data and to prepare maps. Three special maps including every class of the land uses were obtained and a comparison was made to make to limit area and value of each class; finally make accurate evaluation on them.
The different classes areas, percentages, and their representation were counted on mapping outcomes that reached 32 objective maps, through them, changes and classes of land uses were known and observed that contained four classes ( agricultural land, architectural land, barren land , and water). The architectural land class / first level presided all the study years where the highest percentage in 2022 registered 57,899% of the total land of the study area, while the lowest average of the barren land was (2.69%, 2.455, 0,122% ) for the years ( 1986, 2004, 2022 ) successively.
Accuracy points with the colored land use map production from the visual interpretation was used in estimating accuracy of the three maps. The total accuracy of every map was limited. The total accuracy for the years ( 1986, 2004, 2022 ) was (88%,88% , 90% )successively. It was clear that whenever the spatial accuracy of the space image increased, the objective map accuracy increased; as a result, the choice accuracy will be better.
A process of prediction with the happening changes in classes of land uses was done till the year 2042. It was stated that the barren land will disappear in the future due to the spread of the architectural land, as well as with the agricultural land, and water with clear retreating. This is a negative result that refers to deterioration of the agricultural land and a possibility to turning them into the architectural land, while retreating water quantities relates to the climate condition during the thirty coming years.
