Geocoding Historical Data using QGIS

Historical collaborative geocoding

Figure 1. Graphical abstract: Gazetteers of geohistorical objects are created based on information extracted from georeferenced historical maps. Geocoding an historical address is then finding the best matching object based on customised function (semantic, temporal aspect, spatial precision, etc.). Results can be displayed in a dedicated web interface for collaborative editing. Abstract: The l...

Geocoding of Terrasar-x Data

TerraSAR-X is a new German radar satellite that shall be launched in April 2006. The expected lifetime is 5 years. It carries a high frequency X-band SAR sensor that can be operated in different modes and polarisation. The Spotlight-, Stripmapand ScanSARmodes provide high resolution SAR images for detailed analysis as well as wide swath data whenever a larger coverage is required. Imaging will ...

Assessing OpenStreetMap Data Using Intrinsic Quality Indicators: An Extension to the QGIS Processing Toolbox

OpenStreetMap (OSM) is a recent emerging area in computational science. There are several unexplored issues in the quality assessment of OSM. Firstly, researchers are using various established assessment methods by comparing OSM with authoritative dataset. However, these methods are unsuitable to assess OSM data quality in the case of the non-availability of authoritative data. In such a scenar...

Challenges in Geocoding Socially-Generated Data

An investigation into the difficulties facing researchers attempting to geocode data derived from social networking sites for analysis is presented. A number of issues are identified that arise from the differing levels of detail with which people describe their location, and from the reliance on place-names, which do not necessarily constitute unique identifiers for a given location. These iss...
