Spatial analysis of spectral greenness indices and their spatial relationship with dust in Baghdad Governorate

Abstract

Geography studies the spatial patterns present on the surface of the Earth. In its study, it describes the patterns, analyzes the processes that created them, and interprets and determines the relationship between them and other phenomena surrounding them. In this research, changes in land cover and land use of the study area were revealed and monitored, due to the region’s distinctive features. Of particular importance

Being the capital of Iraq and where most human activities are concentrated, satellite outputs had a major role in addressing many soil degradation indicators, such as the Vegetation Index Index (NDVI), where the highest value in the values ​​of this index was in the year 2023, and its area reached (9.97 km2), and it extended spatially in In the west of the study area, there is also an indicator of the biological crust index (Cl), which represents the highest value in the values ​​of this indicator in the year 2023, with an area of ​​(48.76 km2), and it extended spatially in the west of the study area.

A set of techniques were used to find spatial variation in the study variables and to find spatial relationships, namely the correlation technique and Chi-square using the SPSS and GIS programs to produce research maps and reach a set of conclusions and recommendations
