Quickstart subsurface data

DINOloket is a map application that provides access to the largest database on the Dutch subsurface. On this page you will find instructions on how to use this application. This page is entirely about the use of the map for subsurface data. If you want to read the instructions for using the map for subsurface models, view the Quickstart subsurface models.

How to navigate on the map

By scrolling with your mouse you can zoom in and out on the map, so that you can view a larger or smaller area.

You can also use the navigation buttons at the top left:

A window will then appear in which you can search in the following categories:

Object (via identification)
This allows you to search for a specific object by entering the identification number.
This allows you to search for an address in the Netherlands. This can also be a zip code or the name of a city. As you enter the address, suggestions will be given to help you find the right location.
This allows you to search by RD (National Triangulation System) coordinates.
This allows you to select one of the provinces in the Netherlands. The selected province will be outlined on the map.
Water board
This allows you to select one of the water boards in the Netherlands. The selected water board will be outlined on the map.

RD Coordinates

In the right bottom corner of the map the RD coordinates of the position of the mouse are displayed.

Show and hide data on the map

When you open the interactive map, no data is shown on the map. This is because no map layers have been selected yet. At the top right you will find an overview of the available domains. A domain consists of multiple map layers.

With the map layers, the corresponding symbol is also shown to identify the data on the map. By ticking checkboxes the data of the selected map layer is shown on the map.

By activating the "BRO data only" button, only the map layers with BRO data are displayed. By default all map layers are available.

Filter data

Different filter options are available for the map layers. The filters are "grayed out" if they are not available. They become available as soon as the map is zoomed in far enough.

A specific description is available for all filters in the form of a tool tip. The tool tip can be consulted by moving the mouse over the filter.

View object information

By clicking on one of the objects on the map, a window is opened with information about the object.

Screenshots of objects on the map

In the window that has appeared, first the basic data of the object is shown. More information can be displayed with the tabs. The available information and tabs may differ per object.

When multiple points are close to each other, multiple points can be displayed in the object information window with a click action. The arrows at the top of the information window can be used to click through to adjacent objects.

When objects from different map layers are clicked simultaneously, they will be shown in the information window under different tabs.

Order objects

In addition to viewing the information on the map, it is also possible to order the data of a desired area for free. Before you start with this, you must first select a layer in the menu. You can then use one of the selection options to select the desired objects.

There are two selection options within DINOloket.

Rectangular selection tool

With the rectangular selection tool a rectangle can be drawn on the map. Objects within the rectangle will be selected.

Rectangluar selection tool icon By clicking on the button with the rectangle symbol, you can activate or deactivate the selection tool. You make a selection by clicking and holding the mouse on the map. You end the selection by releasing the mousebutton.

It is not possible to move the map while making a selection.

Polygon selection tool

You might not be able to select the required selection with the rectangular selection tool. For example, you want to select only the objects south of a winding river. The polygon selection tool can be used to make a selection with almost any desired shape.

Polygon selection tool icon By clicking on the button with the polygon symbol, you can activate or deactivate the selection tool. You can start a selection by clicking on the map. Unlike the rectangular selection tool, you don't have to hold down your mouse button. With each click on the map, a corner of the polygon is defined. You can drop as many corners as you want. You end the selection by double clicking.

You can cancel the selection by deactivating the polygon selection tool.

While drawing, it is still possible to navigate on the map by zooming in or out and moving the map.

Adjust and order your selection

After you have made a selection, an overview appears with the selected objects. You can now review the selection and optionally uncheck objects if you do not want to include them in your order. The selected objects can be displayed across multiple pages in the overview.
