Integration Between Satellite Images and Spectral Analysis Using The ASD Device to Distinguish Wheat and Barley Plants

The cultivation of wheat and barley crops is one of the most important crops cultivated in Iraq,  which contributes to the economic and social development in the country. Iraq seeks to adopt economic policies aimed at cultivating the two crops and undermining their import with the aim of self-sufficiency in them. The current study relied on studying the spatial distribution of the two crops in Nimrud sub-district and the possibility of distinguishing between them by  remote sensing data, where a landsat 8 images acquired on March 5, 2020 were used, then a digital processing was performed on them. The spectral signature of the two crops was measured, the NDVI was calculated, then the supervised classification was performed by (ILWIS) program. The results showed the appropriateness of choosing the satellite image in March, which is the season for planting these two crops, as they constitute the two main crops in this period before planting other summer agricultural crops, which helped in identifying and distinguishing the two crops. The results also showed that the wheat crop is predominantly cultivated in the region, with an area of (271,797) km2, while the area of land cultivated with barley was small, with an area of (7,303) km2.
