Z_GIS will present Land@Slide at the AHORN2015 conference that takes place in Wildhaus, CH, on the 26th and 27th of November. The German talk with the title “Web-Service für Hangrutschungsinformationen aus Fernerkundungsdaten” will discuss the needs and requirements of geological survey authorities, infrastructure providers and other stakeholders to a web-service for EO-based landslide information. The AHORN conference (http://www.ion-ch.ch/ahorn2015) addresses challenges in orientation, navigation, earth observation and communication and the resulting application fields in alpine areas. This year, AHORN will be organized by the Swiss Institute of Navigation, ION-CH, together with the Austrian and German Institutes of Navigation (ÖVN and DGON).
