Climatic maps of Babylon province, a study using geographic information systems

Abstract

The study aimed to highlight the importance of GIS science in building climate databases, representing, displaying and directing digital maps, introducing the climate map and its preparation methods using GIS programs and choosing the best way to represent climate elements cartographically, and raw data such as maps, satellite visualizations and GPS data were relied on by locating climate stations and the data with a possible reference (tabular metadata) and was based on the map of the administrative province of Babylon and the administrative map of Iraq and the data issued by the official authorities of the station of the study area, which was represented by the stations of Hilla, Karbala, Najaf, Badra, Diwaniyah, Al-Hayy and Baghdad. For 30 years,Previous reports and studies and secondary data derived from primary data that were statistically processed before being entered into the database in the GIS program,The climate maps represented by maps of monthly and annual rates of the actual brightness hours of the province of Babylon were represented in several ways, including the method of cadastral shading, the method of equal lines of solar radiation, the method of graphs, the method of curves, and the map of temperature rates in the province of Babylon represented by maps of maximum temperatures and maps of minimum temperatures, and also in several ways, and the optimal path was chosen for each climatic elementAnd maps of wind speed and direction, relative humidity maps and equal rain maps The study found that climate maps are of great importance through the impact of climate on human life The study stressed the importance of the possibility of using GIS technology in climate mapping as well as preparing the climate database with high accuracyThe study confirmed that the gradient color method suggests the description of climatic elements and has a high visual perception and the study stressed the use of the method of graphs or curves in the representation of temporal and spatial variation according to the Months and seasons of the year of the region studied climatic.
