Whether the real estate market is prosperous or not, purchasing or renting houses always exists. Real estate agencies are market information provider. It is the goal of the consumer and the agency to get sufficient real estate market information. In this paper, an interface was designed which based on information platform and map development tools provided by two main map server providers. In addition, the functions of API between them were compared. The real estate database and digital photos of properties were processed and adopted as resources in this paper. We try to use the function of Google Maps/Earth and Urmap API to build an interface which can show the results of query among real estate database in two- and three-dimensional formats. The result shows that this kind of platform, which combines the two major map server functions, can really activate with the real estate database contains.
