On Parallelizing Large Spatial Queries Using Map-Reduceesent HadoopDB - a combination of Hadoop and Postgres spatial to efficiently handle computations on large spatial data sets. In HadoopDB, Hadoop serves as a means of coordinating amongst various computational nodes each of which performs the spatial query on a part of the data set. The Reduce stage

A Journey from IFC Files to Indoor Navigationular indoor partitions, which helps speed up routing in indoor navigation. Furthermore, we design an algorithm that computes indoor distances involving concave partitions. We conduct extensive experiments to evaluate our proposals. The experimental results demonstrate that our proposals provide effe

Integrating IndoorGML and CityGML for Indoor SpaceGML data from CityGML LoD 4 data set and external references from IndoorGML instance to an object in CityGML data. The derivation and reference of external objects are based on the mapping relationship between feature types in CityGML and IndoorGML to be investigated in this paper. A simple prototyp

Key Frame Selection Algorithms for Automatic Generation of Panoramic Images from Crowdsourced Geo-tas from UGVs for web-based geographic information systems. The proposed algorithms leverage data fusion, crowdsourcing and recent advances in media processing to create large scale panoramic environments very quickly, and possibly even on-demand. Our experimental results demonstrate that by using geo

GeosensorBase: Integrating and Managing Huge Number of Heterogeneous Sensors Using Sensor Adaptors asupport some limited query operations of simple filtering. However, in real-world services, it is expected that various kinds of flexible query operations become more and more necessary to efficiently find out the sensor readings of interest. Therefore, we propose a GeosensorBase system that can eas
