Questions and answers

Have a question? Click on one of the following questions to get an answer:


Do I need a user account to request data?

No, you don’t need a user account to view and request data using DINOloket. In completing your request you only need to fill an email address on which you would like to receive the files and the code shown on the screen.

How can I save visualised data?

Visualisations viewable in the module Subsurface data can be saved as png file (image) and in the module Subsurface models as pdf files by using the ‘Save’ button in the visualisation screen.

How can I search in the map?

Searching in the map is can be done by clicking the button with the magnifying glass on the left of the map screen. Then it is possible to specifically go to a particular object via the identification code, an address (municipality, city, street address), a province, a water board, or a specific point via X- and Y-coordinates.
In addition, several ways are available to navigate in the map:

  • By scrolling with the mouse wheel you could zoom in and out
  • By keeping the left mouse button pressed and moving over the map you could shift the map
  • By pressing SHIFT + left mouse button and drawing a square on the map this area will be zoomed in

I am not able to obtain the data I want from DINOloket. Is it possible, for example, to request a specific query?

Using the interactive map and the diverse search functions on DINOloket, you could retrieve and view much data. In addition, you could request these, without our interference and without cost, for use in your own software. Are you not able to fulfil your demand for data, do not hesitate to contact us. Possibly we can help you, for example by performing a specific query. Be aware, such a request is not part of our standard service. Cost will be charged. In that case, you will be informed and presented with a bid in which we offer our services at cost price.

What is the difference between DINOloket and BROloket?

On DINOloket you can consult data about the Dutch subsurface. This data comes from both the DINO database and the Key Register of the Subsurface (BRO). The BROloket only makes BRO data and models available.

As soon as data are delivered to the LV BRO, the next day they are available at DINOloket and BROloket (nightly update). The advantage of the BROloket is that all the data for the legally required use by administrative bodies are in one place. The advantage of the DINOloket is that, in addition to the statutory BRO data, other data and information about the Dutch subsurface is also offered.

Read more about BRO data via DINOloket (Dutch only).

With the arrival of the Key Register of the Subsurface, a lot of data will be transferred from the DINO database to the BRO. However, not everything will be secured in the BRO. Some historical or non-authentic DINO data have re-use value, but do not fit into the new BRO standards. In order to safeguard this information as well, the new GDNR is being developed: the Geological Survey of the Netherlands Repository. This database fulfils an important function in the performance of the tasks of Geological Survey of the Netherlands. Naturally, the Geological Survey will ensure that the data in the GDNR is made accessible via the current DINOloket. So even data that does not go into the BRO will always remain available.

Where do I find background information about the data in DINOloket?

After ‘Subsurface data’ or ‘Surbsurface models’ has been chosen on the home page (green area), an additional tab ‘Explanation’ is shown which you can use to find information about the data types or models.

Subsurface data

How can I view a groundwater level diagram?

Make sure that in module Subsurface data the data type ‘Well with research data (DINO)’ is visible on the map. Clicking a specific well on the map using the mouse opens a screen with detail information of that object. The main characteristics are shown here. If groundwater level monitoring is done for the well, than the pipes are listed under ‘Monitoring pipes with series of groundwater levels’ (see image). By clicking on the pipe number, i.e. the code in column ‘Id’, a diagram of the groundwater level monitoring with that pipe is shown. Be aware that not for all wells groundwater level monitoring is available.

Why can’t I open all borehole .GEF file in the GEFPlotTool?

It is possible that the GEFPlotTool produces an error message. This may happen, for example, if the gef file belongs to a image file (.tiff) that was included in the delivery. Such gef file does not contain information for the GEFPlotTool to plot as a curve. For more information on the GEFPlotTool, click here.
An alternative is available with which gef files of drilling scan be opened: Boris & Profiler (in Dutch).

Subsurface models

Are the data from older models still available?

A soon as a new release of one of our models is made available, the newest version is used in DINOloket. Do you want to request an older version of a model? That is possible. Send an email with your request to our Service desk:

Where can I make cross-sections through models?

Cross-sections though models can be created in the module Subsurface models.

Where do I find borehole logs of DGM, DGMdeep, REGIS II and GeoTOP?

Borehole logs that were created during the construction of DGM, DGMdeep, REGIS II and GeoTOP can be viewed and requested in the module Subsurface models.

Where do I find information about the reliability of the models?

As soon as you select ‘Subsurface models’ on the home page (green area) ), an additional tab ‘Explanation’ is shown on which information can be found about the models.

Where do I find the models?

The current versions of the subsurface models DGM, DGMdeep, REGIS II and GeoTOP are available in DINOloket.
The models can be viewed and requested in the module Subsurface models. In Explanation the models and the visualisations in DINOloket are briefly explained. Other models (like NL3D) and products derived from the models are available via (in Dutch).

Why do I get more model data files delivered if I select a part of a province or a water board?

ArcGIS files of DGM and REGIS II can only be delivered as zip file of a entire province or water board. You receive the provinces or water boards that are part of area you selected. ArcGIS file of GeoTOP and DGMdeep always contain the full coverage area, independent of the selection made. For SubsurfaceViewer files also the entire coverage area of DGMdeep is deliverd, but for the other models (DGM, REGIS II and GeoTOP) only the tiles included in the selection are included.


How can I deliver data?

DINOloket supplies from the DINO repository and the BRO (Subsurface Key Register). Below, you find per data type the procedure and restraints for data delivery.

For procedures and restraints that are not available online, you could contact the Service desk:

Where do I find the Brackish salt map?

The map of the Brackish salt barrier is available on (in Dutch).

Where do I find the isohypsis map?

You will find the isohypsis map on (in Dutch).
