GIS-based enrichment

    Research output: Contribution in Book/Catalog/Report/Conference proceedingChapter


    Geographical information allow us to reach essential objectives of a survey on personal mobility: making regional O-D matrices; accurate measurement of distance; setting personal behaviours in the geographical context. It is also useful for validation of raw data, during database construction. Collecting geographical information depends on the different possible survey methods that can be used for long-distance surveys. New technologies enable the collection of such information on GIS format directly. But most survey methods still collect place names that have to be translated in geographical coordinates to enrich the mobility datasets. Such an operation, known as geocoding, relies on complementary information that is to sought in geographical databases, which prove to be a valuable capital of information for transportaztion studies.
