Internship
Internships at Imagem
Invest in the Future with Confidence

Choose your internship tropic from the following research areas. You can fill out an application at the end of this page. Note that internships are available for students from the Netherlands, Belgium and Luxembourg, and for English and Dutch languages only. At this moment we do not support overseas or virtual internships, and interns are expected to attend office on all working days.  

Automatic generalisation of the Dutch large-scale map BGT to the mid-scale Top10NL

In The Netherlands both the Large Scale topographic map BGT and the mid-scale topographic map Top10NL are independently maintained. The research would encompass investigating how well BGT can serve as a maintenance source to Top10NL.

Using automated processing to turn an image-matched Digital Surface Model into a Digital Terrain Model

Aerial photographs are available annually to municipalities. They are used to calculate point clouds describing the terrain. But what is calculated is a Digital Surface Model, whereas some applications require a Digital Terrain Model. The purpose of this research topic is to see to which extent this workflow can be automated, taking different data sources like BGT into account.

Extracting tree parameters from point clouds

Aerial photographs are available annually to municipalities. They are used to calculate point clouds describing the terrain. A point cloud based on summer images describes trees and other vegetation with a high precision. Theoretically many parameters could be extracted from that information. One could find the position of the tree, the tree canopy size, the predominant shape of the tree, the exact color and infrared value of the tree and ultimately the type of tree. This could be used to generate important urban indicators like the amount of CO2 captured at night, the economic value and the amount of wood in a tree. Potentially diseases could also be traced.

Recognizing submerged areas from Sentinel-1 RADAR data

Sentinel-1 offers a reliable, reoccurring and free source of RADAR data. And RADAR is very sensitive to water. Theoretically it could be used to find standing water. Clearly for most water in The Netherlands it is accurately known where it is. But in case of significant rain, agricultural can be partially submerged. This is an important indicator for subsidies in the agricultural sector, since standing water is a clear indicator in this process. An independent check on standing water is important. The goal of the research topic is to see how automated processes could be constructed (download, file checks, analysis, reporting) to accurately define standing water through time.

Urban heat management: Optimizing the modelling of heat using thermal infrared data

Satellites measure thermal infrared. This thermal infrared is causally linked to the temperature on the earth. This research topic aims to optimize the calculation of temperatures, based on Landsat 5, Landsat 7 and Sentinel 3 data.

Urban heat management: Modelling the distribution of heat across the landscape

Satellites can help up to visualise the temperature on earth. But many aspects are important when it comes to the temperature. Where satellite images are 2D by nature, Temperature and heat distribution is a 3D sport. Temperature can also change over very short distances. Vertical thermal movement and draught play a different role. Also the absolute temperature, as opposed to the felt temperature, is interesting to model.

The goal of this research topic is to cut up ‘the surface temperature’ to effects at different heights, and to model air temperatures from surface temperatures. Accurate height models and remote sensing techniques should be used for that.

Crashtender routeplanner

When disaster strikes, especially near airports, the fire brigades use so-called crashtenders. These huge machine can traverse streets as well as going cross-country to the place of the disaster.

Route planning for a crashtender is not easy. Traversing the streets is a capability that many route planners offer. It is a classic vector network analysis. But at some point the crashtender turns left or right, and then the route planning moves to the raster domain. A least cost path calculation. Both speed and economic damage are arguments in applying the optimal route. The goal of this research topic is to set up a hybrid vector-raster route planner.

Turning geocoding into something operational for the Benelux

Within the Benelux there are many types of addresses. All of these addresses should be geocode-able. GeoMedia has advanced capabilities for this. But for each address type, a particular geocoder should be implemented. The goal of this research topic is to generate geocoders for the following address types:

  • Dutch level 6 postal codes
  • Dutch municipalities and built up areas
  • Dutch addresses
  • Dutch building registration (BAG)
  • Flemish CRAB
  • Flemish addresses
  • Walloon addresses
  • (German speaking addresses)
  • Luxemburg addresses
  • Optional: Addresses on the islands of Saba, S. Eustatius & Bonaire

Parcel division with regard to the Environmental Law (Omgevingswet)

The Dutch Environmental Law defines that certain house extensions are allowed, as long as they are built on the correct parts of a parcel. The front wall cannot be altered, whereas the back wall of a house can be changed to a certain degree. For this reason, it is important to define what a front and back façade is. These virtual lines need to be extended to cut up a parcel. This results is a parcel division, each having a different meaning in the Environmental Law. The purpose of this research topic, is to come up with an algorithm to divide these parcels in an appropriate manor.
