What is GIS Software?

GIS (Geographic Information System) software is used to capture, store, analyze, and present spatial and geographic data. These tools allow users to map, visualize, and interpret complex data related to geography, helping to make decisions based on location-based insights. GIS software supports a wide range of industries, from urban planning and environmental management to transportation and utilities, by enabling the analysis of geographical patterns and relationships. Features often include data layering, spatial analysis, cartographic tools, and the ability to integrate with other systems for more comprehensive data analysis. GIS software is invaluable for planning, resource management, logistics, and location-based decision-making.

    CADObject
    CADObject is a unique development of "ExonIT" LLC which allows to create of application systems and WEB services that provide interaction between CAD and GIS apps. Creation and managing of project documentation exacting the customer's requirements. Decreasing the operational costs thanks to real-time updating of documentation. Maintenance of the history of the object lifecycle with instant access to the needed information in real-time. Integration with existing enterprises' systems. The main difference between CADObject and other similar products is, that in process of data exchange between CAD and GIS, CADObject creates an object data model whilst converting. During this process, all the standard graphic symbols are recognized, united into separate objects according to a certain classifier, and transferred to a spatial database. Each object has a specific entry in the database, which allows the development of analytical spatial solutions.
