Short Description

Since this is a very wide range of applications, the individual devices are combined into the following infrastructure / research units:

1.Photogrammetry / UAS - Unmanned Aerial Systems (civilian drone): GeoCopter / UAS, various cameras and measuring equipment
2. GNSS / Surveying: Various GNSS / GPS surveying equipment
3. General recording or evaluation devices

Research Services

• GNSS (incl. correction data for the Area Salzburg City):
Measurements of any kind and requirement (from meters to the CM range – keyword 2 – frequency measurements incl. correction service).
• UAS / GeoCopter / Photogrammetry:
Timely remote sensing in the close range with correspondingly high ground resolution + additional or other sensors for data acquisition (temperature, infrared, gas sensors...).
•Analysis and calculations:
Evaluation methods from orthophoto generation to the modeling of detailed spatial or surface models.

Methods & Expertise for Research Infrastructure

As indicated in the title, this core facility consists of research questions and equipment that can be assigned to the category of primary "geodata collection". Since this is a very wide range of applications, we would combine the individual devices into the following infrastructure / research units:


1. Photogrammetry / UAS - Unmanned Aerial Systems (civilian drone): Here, above all, the GeoCopter / UAS serves as a carrier for camera and measuring equipment with the primary goal of taking up-to-date aerial photographs and evaluating them with a variety of methods. This goes beyond the creation of simple orthophotos (=geo-referenced terrain corrected aerial photos) via evaluation methods to automatically generate detailed, fully textured 3D or surface models from photos to special sensors in which the UAS serves as a carrier.

2. GNSS / Surveying: Depending on the requirement profile, GNSS receivers with an accuracy from 2 meters up to 2/3 cm are used in numerous research questions (Monitoring, registering point measurements - see also point 1, glaciological measurements ....).

3. General recording or evaluation devices: This includes, above all, IT infrastructure that is suitable for data recording in the field (outdoor), suitable in its construction and robustness (data logger) or corresponding performance for sometimes very computational-intensive analysis - and modeling calculations required (server).
