Propagation of positional error in 3D GIS: estimation of the solar irradiation of building roofs
TL;DR: The extension of the theory of error propagation in GIS from 2D to 3D models using a Monte Carlo simulation and the implementation of a CityGML-compliant software for estimating the solar irradiation of roofs are investigated.

Quantifying positional error induced by line simplification
TL;DR: Results show that error can be modelled at an aggregate level using cumulative frequency curves and their confidence limits, and shows that management of simplification induced error is possible using simple tools well within the reach of GIS users.

Uncertainty-aware visualization and proximity monitoring in urban excavation: a geospatial augmented reality approach
TL;DR: In this article, a dynamic approach to incorporate positional uncertainties of buried utilities into an uncertainty-aware, geospatial-AR system for real-time visualization and proximity analysis is presented.
A fuzzy set approach for modelling time in GIS
TL;DR: An application of fuzzy set theory to perform temporal interpolation in a raster GIS database to simulate spatial changes between consecutive snapshots registered in the database is described.

OpenJUMP HoRAE - A free GIS and toolbox for home range analysis
Stefan Steiniger,Andrew Hunter +1 more
TL;DR: This article presents a free and open-source home range analysis toolbox that focuses on the evaluation of GPS collar data, aims to be fairly straight forward to use by the wildlife manager, and integrates with a desktop GIS to allow data analysis beyond the creation of home ranges.
