(What is this?)

Recent advances in surveying technology and better availability of high precision surveying tools made it easy for geomorphologists to benefit from data with higher spatial resolution as well as data with much better precision than just 10 years ago. In this session we want to (i) increase the awareness of modern surveying techniques and their application to geomorphology, (ii) provide a platform for researchers to present their experiences with laser scanners, range cameras, close range photogrammetry, terrestrial LASER & RADAR as well as other new surveying tools and (iii) address the question how valuable more precise data and new surveying techniques really are - is our process understanding / are our landscape models ready for high resolution data? Are current models ready for data with mm resolution of a field site? What problems can really be solved by better resolution and better precision? What are the problems during data acquisition?

The proposed session has an overlap with ISPRS Commission V Working Group V/6 - "Close range morphological measurements for the sciences". While the ISPRS commission meetings are typically visited by professionals of geodesy a similar session at EGU would allows better communication between professional surveyors and geomorphologists.
