The purpose of this paper is to combine a GIS technology with data mining techniques and visualize the results on a map. Using this application a user can decide where to build his new store depending on geography queries and data processing. For this reason the information system can be splitted in two main categories. The first one is the GIS application that is responsible for storing and managing geographical data and for the projection of data in the map. The second one is the Data Mining process that is responsible for the data processing depending on user’s queries. Big vendors like Google and Microsoft gave a depth research on GIS Systems. The two big companies developed not only these services but also created building tools for developers’ G.I.S. applications. The second part of the information system is the data processing. The database contains a huge amount of data but the problem is how the system is going to know which of these data is important for data process and what kind of algorithm is going to be used. To solve this problem I built a wizard asking user question. This wizard has five steps, within these steps user is going to select data. When the data is sent to the server the data mining process starts and the SimpleKMeans algorithm classifies the data. The most important part of the application is the visualization of data. It is very essential for the user aspect to see the results in the map. At the end the user is going to observe in the map the groups (clusters) of selected stores from the data mining process and which group belongs the new store.
