Modelling Spatial Relations by Generalized Proximity Matrices
One of the main challenges for the development of spatial information theory is the formalization of the concepts of space and spatial relations. Currently, most spatial data struc...

Data-Parallel Primitives for Spatial Operations
Data-parallel primitives for performing operations on the PM1 quadtree and the bucket PMR quadtree are presented using the scan model. Algorithms are described for building these ...

Spatial and Behavioral Types in the Pi-Calculus
We present a framework that combines ideas from spatial logics and Igarashi and Kobayashi's behavioural type systems, drawing benefits from both. In our approach, type systems...

Spatial Indexing into Compressed Raster Images: How to Answer Range Queries Without Decompression
The maintenance of large raster images under spatial operations is still a major performance bottleneck. For reasons of storage space, images in a collection, such as satellite pi...

Laplacian-based consensus on spatial computers
Robotic swarms, like all spatial computers, are a challenging environment for the execution of distributed consensus algorithms due to their scale, diameter, and frequent failures...
