The possibility of identifying harmful plant spots among agricultural fields by using satellite images in the lower Euphrates Basin

Abstract

The aim of the research is to trace, locate locations and distribution the areas of harmful plants spots by selected locations in the Lower Euphrates Basin using satellite images, and geographic information systems (GIS)., to show it in an thematic map in order to present it, to the authorities concerned with controlling harmful plants to limit the spread of the reproductive parts of these plants within the agricultural fields. Image from Google Earth for the study area with a spatial resolution of 50 cm was extracted by the Russian program SASPlanet, and image from the Sentinel-2 multi-spectral satellite with two spatial 20 m and 10 m resolution in the sixth month of 2019. In addition to using ENVI.5 software to study the spectral behavior for some related sites. The method of visual interpretation of the images and the calculation of areas were adopted by ArcGIS, and then the Normalized Digital Vegetative Index (NDVI) was calculated in all spots. It was found by the use of the means and method of research for the possibility of developing thematic maps of harmful plants by integrating the two previous methods in general with the recommendation to use more accurate satellite images of 10 m with respect to the Sentinel-2, in order to obtain more accurate results in this field.
