gis

GIS laboratory

We use GIS for our daily work, from simple map design to advanced data analysis.

We own a number of high-performance PCs, all equipped with the following GIS software

  • DELFT 3d (SLCC group license)
  • Global Mapper (SLCC group license)
  • Agisoft Photoscan (SLCC group license)
  • Trimble Pathfinder Office (SLCC group license)
  • ArcGIS 10.2 (University of Bremen License)
  • MATLAB (University of Bremen License)
  • Qgis
  • Grass GIS
  • Google Earth Pro & Google Earth Engine access
  • Surfer (MARUM License)
  • Grapher (MARUM License)

All our PCs are connected to a Lenovo EMC cloud server, which backs up our data daily.

We also subscribed to a Microsoft Sharepoint account for advanced sharing and database app building.

Pressure transducers

We use portable pressure and temperature PT2X loggers to collect nearshore wave data.

Our ten transducers can be fixed to a chain or fixed to the sea bottom, and can collect data at high frequency (8 Hz) for several days.

Remotely piloted aircraft systems

We own two small remotely piloted aircraft systems, which we use regularly for coastal monitoring studies.

  • A small copter, hardware by DJI Innovations (model Phantom 2), modified to meet our custom specifications by flyingeye.
  • A fixed wing drone by Lehmann Aviation (model LA300)

On these drones, we mount either a gopro4 camera, with modified lens to avoid effects of the lens distorsion on photogrammetric reconstructions, or a canon S100 camera with firmware software modified to shoot aerial pictures.

As a base station, running the software necessary to set up and fly our drones, we use a Windows 8 ASUS tablet.

We are also in contact with companies in different countries active in the world of Unmanned Aerial Vehicles. These companies own drones that can transport heavier payloads and have experience in obtaining authorizations to fly in different countries.

DCIM100GOPRO

GPS system

The group owns a GPS system that allows obtaining precise topographic measurements anywhere on the Earth’s surface.

The system is a Trimble GPS composed by:

  • Pro XRT Receiver
  • Tornado Antenna
  • Juno 5D handheld with Terrasync centimeter edition software
  • Trimble LaserAce 1000 Rangefinder

Starting January 2015, we also have available a 3-years subscription to Omnistar G2 Global.

OmniSTAR G2 represents the most recent advancement in OmniSTAR subscription service offerings. It is a worldwide dual frequency high-accuracy solution which uses Orbit and Clock correction data. OmniSTAR G2 includes GLONASS satellites and GLONASS correction data in the solution. The addition of GLONASS to the solution significantly increases the number of satellites available which is useful when faced with conditions that limit satellite visibility, such as terrain, vegetation or buildings. OmniSTAR G2 service provides short-term accuracy of 1-2 inches and long term repeatability of better than 10 centimerers, 95%CEP. It is especially suited for operations in areas where trees or buildings may block the view of the sky.
