Description:
In order to implement indoor spatial information services, we need an indoor spatial data server. However due to the differences of indoor space from outdoor, most conventional geospatial data servers are not adequate for indoor spatial data. First the position in indoor space can be specified by the identifier of cell containing the position rather than (x,y,z) coordinates. Second, indoor space is considered as a set of non-overlapping indoor cells unlike outdoor space. Third, the indoor distance metrics must be differently defined from Euclidian space considering obstacles such as walls, doors, and stairs. We developed a spatial data server called ISA (Indoor Spatial Awareness) server to meet the requirements of indoor spatial data and have been working for converting it to an open source using GeoTools. With the ISA server, we can store and manage indoor spatial objects, whether stationary or mobiles, and retrieve objects with indoor spatial predicates. We expect that this server will be used as a common data server for indoor spatial information applications
