Ortelium at a glance The Ortelium web platform manages dynamic atlases of different Atlas operators. These atlases collect and visualize a variety of data that has a location and time reference and evaluate it in real time. Operators are e.g. authorities, public bodies or companies carrying out digitized environmental monitoring. The data may include technical data from measuring instruments or other data sources. In specific atlases, you can enter your own observations via the Ortelium app or a web form. As an external user, you can visit the atlases as a guest if guest access is available. For an extended use of the Ortelium web platform, a general registration as a member on the Ortelium platform may be necessary. Here we ask for your e-mail address in a double-opt-in procedure and save it. In addition to this data privacy policy, you will need to recognize general terms of use of the Ortelium web platform. The operators of the various atlases are each responsible for the data privacy on their specific atlas, and provide own data privacy policies and special terms of use that apply to the specific atlas. You must therefore separately agree to the use of one or more atlases - both as a guest and as a member. To use the Ortelium application an internet connection is necessary. This can result in costs for data transmission.
