Visual Analysis and Semantic Exploration of Urban LIDAR Change Detection
TLDR
We present a method of LIDAR change detection that maintains accuracy by only using the raw, irregularly spaced LidAR points, and extracts relevant changes as individual 3D models. Expand

Multi-Focused Geospatial Analysis Using Probes
TLDR
We apply a probe-based interface to geospatial visualizations to empower users with the ability to observe, coordinate, and compare data across multiple local regions. Expand

Multi-touch 3D exploratory analysis of ocean flow models
TLDR
We present a system that employs a combination of stereoscopic rendering, to best reveal and illustrate 3D structures and patterns, and multi-touch interaction, to allow for natural and efficient navigation and manipulation within the 3D environment. Expand

A linked feature space approach to exploring lidar data
TLDR
We introduce a linked feature space concept that allows users to make regular, conjunctive and disjunctive discoveries in non-uniform LIDAR data by interacting with multidimensional transfer functions. Expand

Hierarchical simplification of city models to maintain urban legibility
TLDR
In this paper, we present a novel approach to simplifying city-sized collections of 2.5D buildings based on the principles of “urban legibility” as defined by architects and city planners. Expand
