Abstract :Geographic Information Systems (GIS) software, which is programs that offer various geographical functions, has an important place in the GIS industry. GIS software has 3 main parts: user interface, tools and data manager. A desktop computer or a central server is needed to carry out operational activities in GIS. Cloud Technology is defined as software applications, data storage services and processing capacity that are accessed over the internet, and it provides access to all kinds of information and personal data from anywhere at any time, even with the lowest capacity device. For all these processes, it performs a multi-server connection via a digital network. With the development of cloud computing systems, it is possible to store, process and share large data stacks in virtual machines on the web. Cloud technology's Software as a Service (SaaS); providing software as a service, Platform as a Service (PaaS); platform service and Infrastructure as a Service (IaaS); There are three building blocks, namely the server infrastructure service. The most well-known leading software in the GIS sector in the world and in our country; Esri, Intergraph, Autodesk, QGIS, MapInfo, NetCAD GIS etc. are software. In this research, software in Geographical information systems and Cloud GIS software were examined. Keywords : Cloud GIS, Cloud Computing, GIS Software
