Hacker Cartography: Crowdsourced Geography, OpenStreetMap, and the Hacker Political Imaginary
In this paper I trace the origins of “neogeography” (a constellation of new mapping practices and populations on the geospatial web) to its roots in computer hacker culture, notably through early mapping mashups, known originally as “map hacks”. I argue that a return to the figure of the hacker—via the proposed concept of hacker cartography—offers a productive lens for understanding the afforda...

متن کاملAssessing Data Completeness of OpenStreetMap in the UK through an Automated Matching Procedure for Linear Data
OpenStreetMap’s (OSM) increasing popularity and density urges researchers on studying its data quality. When this includes comparison with a reference dataset, a data matching is necessary for the comparison to be meaningful, usually performed manually at data preparation stage. We propose an automated matching method specifically designed for OSM in the UK, based on a multi-stage approach that...
متن کاملAssessing the Effect of Data Imports on the Completeness of OpenStreetMap - A United States Case Study
The assessment of OpenStreetMap (OSM) data quality has become an interdisciplinary research area over the recent years. The question of whether the OSM road network should be updated through periodic data imports from public domain data, or whether the currency of OSM data should rather rely on more traditional data collection efforts by active contributors, has led to perpetual debates within ...
