Author of GRB, PICC and URBIS to OSM migration toolkit
I professionally occupy myself in studying the GRB dataset, PICC and URBIS datasets on accuracy, usuability. One of the specialisations is to combine, merge and enhance external datasets with OpenStreetMap data and the other way around. I subsequently created a web based toolkit to assist OSM mappers to merge, verify and input data from GRB (Grootschalig Referentie Bestand) with OpenStreetMaps , PICC and Urbis into OSM.
