3d.graz.at: efficient online city model

Abstract

We show the procedure used in city of Graz, which converts the normal photogrammetric measurements and other data layers into 3d city model automatically. We use ArcGIS© online to organize the model into projects and publish with CityEngineViewer© to present the city model online with extendable functions, all for free! One practical way from 3d model building to online presentation is shown.
