Abstract

The development in the field of computer was greatly reflected in cartography in form and content, and this in turn led to a great change in the field of map production using geographic information systems techniques, and the main goal of this research is to prepare an aggregate map as it is called (deductive or comprehensive) in the manner of congruence. The maps are based on the (Arctool box) tool for spatial analysis from the (Arc GIS) program. An applied study has been conducted for the agricultural economic activity for the research area, as the agricultural activity is a basic pillar of the economic policy of any country. Therefore, an aggregate map (comprehensive) was first prepared showing the impact Natural factors on the agricultural activity of the governorate as a catalyst or hindrance to that agricultural economic activity by conducting the process of matching geographical factors as a group of layers and reaching the production of a single (comprehensive) aggregate map derived from simple cartographic congruence. Another comprehensive map was produced through the matching procedure between The variables that have a large role in the variation in the agricultural economic activity of the population, the most important of which is the economic composition of the population, and include (the active population, the economy The number of agricultural workers, the area of ​​cultivated land, the amount of crop production (wheat, barley and rice) and a comprehensive economic map was prepared that illustrates the agricultural economic activity that can be relied upon in the analysis. It touched upon the most basic stages that were used to produce maps, starting with the stage of data collection, then the stage of entering it and creating the database, then the stage of matching it to highlight the spatial relationships between phenomena and finally the stage of producing maps
