An apartment web service is a web site intended to provide
online services to the residents. With the availability of global
positioning systems and the development of new technologies,
the access of geo-spatial information has drawn great attention
for information retrieves. This research is focused on
developing an online service for an apartment to provide geospatial
information. In this paper, a fuzzy spatial querying
model under uncertainty is used to improve spatial querying.
An inexact inferring with the certainty factor is investigated.
An online spatial database for an apartment is implemented by
utilizing PHP with MySQL database. Demonstration shows
that the system can provide visitors with the amount of
significant geo-spatial information about the apartment.
Moreover, fuzziness and uncertainty are mainly concerned.
Querying examples are provided.
