摘要：With this paper we plan to initiate an open ISPRS related LBS competition. The contact point for all interested in this competition is the home page of ISPRS working group 4.6 (http://www.isprswg46.hft-stuttgart.de). This initiative aims at taking up current trends in GeoTagging in combination with a proposal of a location based service. The basic idea of the initiative is to create a very special window to LBS technology and relate it to a more traditional field of expertise of the ISPRS. GeoTagging stands for the process of adding metadata suitable for geographical identification of resources to various media, for example, to images, to websites or to RSS feeds. A review of the state-of-the-art of GeoTagging in this paper will reveal that this process requires a lot of interactivity and automating this process is one of the challenges. The competition is based on the creation of a location based weblog (blog) application. Given the website where entries are made available, images or sound recordings combined with location data for GeoTagging can be uploaded. The recording equipment for the images and the location data should support automated GeoTagging, for example, by using digital cameras combined with external GPS receivers and mobile computers. But other components and concepts like those based on mobile phones may also be taken into account. Some first experiments in this direction have been carried out by students of our university. The idea of an LBS service "height for a certain object" using a camera and a GPS mouse is the basis of this student work. We shortly report about first results and outline the forthcoming steps
