Project Goals:
Users have
more and more demand for launching spatial queries for finding friends or
points of interest in indoor spaces. However, existing spatial query evaluation
techniques for outdoor environments (either based on Euclidean distance or
network distance) cannot be applied in indoor spaces because these techniques
assume that user locations can be acquired from GPS signals or cellular
positioning, but the assumption does not hold in covered indoor spaces. We
study various indoor spatial data management challenges in this project.

Research Challenges:
Existing
spatial query evaluation techniques for outdoor environments (either based on
Euclidean distance or network distance) cannot be applied in indoor spaces
because these techniques assume that user locations can be acquired from GPS
signals or cellular positioning, but the assumption does not hold in covered
indoor spaces. Furthermore, indoor spaces are usually modeled differently from
outdoor spaces. In indoor environments, user movements are enabled or
constrained by entities and topologies such as doors, walls, and hallways.

Broader Impacts:
The
research results of this project will improve the performance of numerous high
value-added indoor applications and hence benefit the economy of our country.
In addition, the ability to be able to locate people in indoor spaces will
improve emergency response. The project will promote teaching, learning, and
training by exposing both undergraduate and graduate students to mathematical
and technological underpinnings in the field of spatial data management.
