Delivering geotechnical cone penetration tests

Is it worth it?
By sharing your data of the subsurface, like data of geotechnical cone penetration tests, you contribute in a meaningful way to new developments. Reliable information and expertise of the subsurface contribute to lesser costs of failure for the community in various contruction projects, to safer constructions and to a sustainable future. If together we give the subsurface the attention it deserves, we could benefit now and in the future. Therefore, a lot of effort is put in the realisation of the Subsurface Key Register (Basisregistratie Ondergrond, BRO).

BRO: what does that mean for geotechnical penetration tests?
Due to the BRO, delivery of data to DINO has changed. It could be that from now on you are even obligated by law to delever certain data to the BRO, like data of geotechnical cone penetration tests. Read more about this on basisregistratieondergrond.nl (in Dutch) or consult directly this decision tree (in Dutch). Unfortunately, data of geotechnical cone penetration tests that are not eligible for the BRO (see also for this the decision tree), could not be registered in DINO anymore. An exaption to that are the images of geotechnical cone penetration tests.

Images
Images are not part of the BRO and they could still be supplied to DINO. See the information below about the delivery of images.

1. Image with metadata (alternative for archives)

1.1 How can I deliver data?

Per email via support@geologicalsurvey.nl. If delivery per email is causing difficulty, alternative solutions could be considered.

1.2 In which format could I deliver data?

Images could have the formats JPEG, PDF or TIFF. In addition to the images, you will need to provide an Excel-file with metadata of the images/objects.

1.3 Which conditions apply to the data?

 Image
For the images there are no specific demands. However, that quality should be sufficient to make the information well legible. At least one image should be supplied per cone penetration.

Metadata file
Per delivery an Excel-file (example metadata file (in Dutch)) should be provided in which, per image and cone penetration, the metadata is included. In this file the following aspects should be described:

Mandatory for processeing and reuse:
  1. Name of image file
  2. Coordinate system/Horizontal datum reference
  3. X-coordinate
  4. Y-coordinate
Preferred for reuse:
  1. Cone penetration length (essential for selection)
  2. Date/time survey
  3. Local vertical reference point
  4. Standard and quality class
  5. Reference plane
  6. Reference height
  7. Method determining place
  8. Method determining height
Preferred for an optimal control:
  1. Work number survey
  2. Project number
  3. Project name
  4. Operator
  5. Accoutable party
If the information is not available in such way, see other options under 2.

1.4 What will be validated?

After delivery, the data are validated on format and conditions. Doubling in surveys is also checked, within the delivery as well as in respect to the data already in DINO. To be able to execute this validation correctly, it is important that the metadata is provided as complete as possible.

1.5 What is the processing timespan?

Processing of the data takes thirty workdays on average.

1.6 Do I receive a notification of the validation and processing?

You will receive a notification if the data are not conform the agreed format and/or the conditions. If the data are valid, then you will receive an overview with NITG-numbers under which the data are processed and available.

1.7 Where will the data be made available?

After the data are processed in DINO, they are made available the next day via dinoloket.nl.

1.8 What are the costs?

For processing the data in this form processing costs are charged. Per delivery these are € 250,- plus € 1,- per image.

 

2. Other forms (for example paper) or formats.

If you have other forms or formats available, these cannot readily be added to DINO. We may be able to help you processing the data to make them available via www.dinoloket.nl. For this you can contact support@geologicalsurvey.nl.
