About TSAS


ACM Transactions on Spatial Algorithms and Systems (TSAS) is a new scholarly journal that publishes high-quality papers on all aspects of spatial algorithms and systems and closely related disciplines. It has a multi-disciplinary perspective spanning a large number of areas where spatial data is manipulated or visualized (regardless of how it is specified - i.e., geometrically or textually), such
as: geography, geographic information systems (GIS), geospatial and spatiotemporal databases, spatial and metric indexing, location-based services, web-based spatial applications, geographic information retrieval (GIR), spatial reasoning and mining, security and privacy, as well as the related visual computing areas of computer graphics, computer vision, geometric modeling, and visualization where the spatial, geospatial, and spatiotemporal data is central.  READ MORE

Call-for-papers: ACM TSAS has issued a call for papers for its inaugural issue. Please use manuscriptcentral (http://mc.manuscriptcentral.com/tsas) to submit articles, check the status of articles and for reviewing tasks.

Spatial Partition-based Particle Filtering for Data Assimilation in Wildfire Spread Simulation

Particle Filters (PFs) hold great promise to support data assimilation for spatial temporal simulations to achieve more accurate simulation or prediction results. However, PFs face major challenges to work effectively for complex spatial temporal simulations due to the high dimensional state space of the simulation models, which typically cover large areas and have a large number of spatially dependent state variables. To effectively support data assimilation for large-scale spatial temporal simulations, this paper develops a spatial partition-based particle-filtering framework that breaks the system state and observation data into smaller spatial regions and then carries out localized particle filtering based on these spatial regions. The developed framework exploits the spatial locality property of system state and observation data, and employs the divide-and-conquer principle to reduce state dimension and data complexity. Within this framework, a two-level automated spatial partitioning method is presented to provide automated and balanced spatial partitions with less boundary sensors. The developed framework is applied to a case study of wildfire spread simulations and achieved improved results compared to using standard PFs-based data assimilation methods.
