Those of you who chose to participate in workshops will be rewarded with 1 ECTS point for their work. For this reward system to work, we'll need your university's ECTS coordinator's e-mail address, in order for them to send us a "Learning Agreement" document, that will enable us to provide you with the certificate for participating in workshops (which you'll be getting once when you finish the workshop of your choice).

OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways.
OpenStreetMap consists of three key parts: data, wiki and software. Data consists of nodes and ways which are tagged with feature descriptions (meta data). Second key part is the wiki, which gathers all available information about OpenStreetMap. Third part is the software developed around and for the OpenStreetMap which is easily accessible from subversion repository.
Everything in OpenStreetMap is open sourced, and every decision is crowd sourced which means everyone can be a part of OpenStreetMap. OpenStreetMap uses two licenses, GPL for the software and CC-BY-SA for the data. There are some issues with CC-BY-SA, as it does not cover database data, so there are plans to use new ODbL (Open Database License) which was developed by OpenDataCommons.org specifically for this purpose. Basically this means that you can do what ever you want with the data as long you mention original creator and the license.

While at the computer, participants will be given a Digital spatial geodetic map (SPM). The task will consist of designing a road on top of the given map, by using special road modeling software. The road is made up of three main parts: a line, a spiral and a curve. Participants' task will be to determine coordinates of main points (TS, PC and PT) and 10m points. Once they are out in the field, participants will have to stake out those points, by using two geodetic methods:
GPS RTK method (Topcon HiperPro system)
Polar method (Leica 1200 TPS system – robotic station)
The aim is to compare those methods in several ways:
Precision
Reliability
Efficiency
...

Recent developments of measurement technology enabled surveyors to dramatically reduce the fieldwork necessary to collect detailed spatial information in various environments. Historically, geodesists needed hours and days of measurements in order to extract only a few points with accurate coordinates. Recent developments in space geodesy were important for fast data acquisition in open space without obstacles between the satellites and the station.
Three-dimensional laser scanning is the second revolution in geodesy which works inside buildings or tunnels as well. As a remote sensing methodology, laser scanning captures tiny details in all directions without the need for special markers on surveyed objects. Laser scanners evolved from expensive, heavy prototypes to “normal” surveying instruments. The speed shifted from some thousands of points per second to one million points per second! The computer hardware and available software has been significantly improved in order to process resulting huge point-clouds into objects and meshes. New technology brings a lot to the surveying world, offering the competitive edge for younger experts capable of successful coping with new technology, tied with information and communication technology.
The workshop will give the insight into this new technology to the participants. Two laser scanners (Trimble GX 3D and Faro Photon 120) will be presented to students. Joint field work is planned, together with processing of results.

During the IGSM, a workshop about geodetic instruments will be held. During the workshop, students will have to resolve given tasks in the shortest possible timeframe, with increased precision. Tasks will be field-type, and will be carried out in the proximity of the building of the Faculty of Geodesy. The best participant will be rewarded. The purpose of the workshop is to demonstrate personal skills and to have fun.
