HiAccess: High-resolution Accessibility Analysis with High Performance Geographic Information System
Pages 28 - 31
Abstract
Accessibility is an important issue in transport geography, land planning and many other related fields. Accessibility problems become computationally demanding when involving high-resolution requirements. In this demonstration, we present an accessibility analysis toolbox with open source code1, named HiAccess, based on a high performance Geographic Information System, which promotes the performance of geocomputation by leveraging the power of high performance computing. HiAccess demonstrates the striking performance of measuring high-resolution (using 100m x 100m grids) accessibility of a city (in total over 250k grids, roads with 232k segments, 40 facilities) in 1 second without preprocessing, while ArcGIS takes nearly 1 hour to achieve a less satisfactory result.
