Daten aus OSM extrahieren und in QGIS weiterverarbeiten (fossgis2015)

from Chaos Computer Club - recent events feed (high quality) · host Claas Leiner

Die OSM-Daten enthalten viele umweltrelevante Informationen, die auf den veröffentlichten Webkarten nicht offensichtlich erkennbar sind. Mit Hilfe von QGIS lassen sich diese Informationen auswerten und in neue aussagekräftigen Karten umsetzen. Der Vortrag erläutert die Fragestellung am Beispiel der Verteilung von Windkraftanlagen in Deutschland. Angefangen vom Import der deutschlandweiten OSM-Daten in eine PostGis-Datenbank, über die Abfrage der WKA-Standorte bis hin zur Präsentation der Verteilung in einer farbigen Flächendichtekarte, die aus einer interpolierten Rasteroberfläche erzeugt worden ist, welche die Anzahl der Windanlagen im Umkreis von 20km darstellt. Dabei kamen Abfrage- und Geoverarbeitungswerkzeuge aus QGIS sowie das GRASS-Modul zur Spline-Interpolation (v.surf.rst) zur Anwendung. about this event: https://fossgis-konferenz.de/2015/programm/events/775.de.html
