2nd Release April 2020

    • Finding a location has been made easy with the addition of an optional search bar. Just check the checkbox in your viewer setting and you’ll find a searchbar at the top of your info-block.
    • Go to GPS Location on load. Another optional feature added to the viewer. When turned on users will be prompt to share their GPS location with the viewer. The viewer on load will automatically move to that location.
    • Go to GPS location button. When the on-load feature is not what you need, but you do want people to go to their GPS location activate the GPS-button in the viewer settings. A “target” button will appear and when clicked the user will be prompt to share their location and if they do the viewer will move to that location.
    • Start a viewer with a GPS coordinates. Add the lat=x and lon=x variables to the querystring and the viewer will load on that location.
    • Start a viewer with Rijksdriehoek coordinates Add the X=x and Y=x variables to the querystring and the viewer will load on that location.

    • In the info block we have a small line of text. This text can now be replaced with custom html. Give a little information about the intention of your application. As it is html you can use images and styling. Javascript is not supported.
    • Printing has had an update. Layer transparency and layer order as you see them in the viewer are used when printing to PDF. Making the printing result more WYSIWYG.

    • The info-block in the vector editor was broken. It would not “scroll-out” when working with vectors. This has been fixed.

Release April 2020

Fully consultable ‘Ruimtelijke plannen’ layer

Ruimtelijke plannen
  • We’ve made the ‘Ruimtelijke plannen’ aka ‘Bestemmingsplannen’ layer consultable. Now displaying the same plan information you already could find on our public map Granting you and your users access to thousands of plans, rules & regulations all within your application.
Viewer browser Interaction
  • We’ve added the ability for interactivity to our viewers. On map-clicks and measurements the viewer can post a message to the browser containing relevant information to the activity.
Map clicks
You’ll receive a JSON string containing the coordinates of the click and all available layer information for that location,
Measure line
On completing a line measurement (double-click) you’ll receive a json string containing the measured distance.
Measure Area
On completing a measurement of an area (double-click) you’ll receive a json string containing the measured area.

In order to make use of the Postmessage capability you must add a listener to your application. See our documentation for example code.

Banner interaction

The interactivity is increased further with the addition of the ability to add a banner-image per layer to the Layer information block. The banner is appended to a index key of the layer’s information structure and displayed below that value. Currently we support the following image-formats:

  • JPG
  • PNG
  • SVG
  • GIF

URL’s given to the banners will open into a new tab.

Banners can be used on all layers, including external ones.

Consultable Outline
The outline layer was an always “on” consultable layer. Now the layer can be turned of. Still displaying but giving no information when clicked. Helping to keep your dislayed information cleaner and clearer.

Translating index keys on the Outline layer (dossiergrens) gave an error. We fixed this, translation now work again on all layers including external layers.

Release March 2020

Data Improvements
  • Kadaster data daily up-to-date

We have increased our update cycle of Kadaster data, updating the Perceel data every day.

New Feature
  • Shape File Import

Replacing the shape file-upload function. Shapefiles are uploaded and imported in the background allowing us to import large and complex shape files.

See Import a shapefile to vector layer

  • The option “as WMS” is checked by default in our dashboard to allow for faster loading of complex vector layers.
  • The shape file upload has been replaced by the shape import. It will be supported until the end-of this version.

Release January 2020

New Feature
  • For most layers it is now possible to translate field names to a more meaningfull name.

See Layer fields translations & filters

Both translations and filter fields can now be accessed through our dashboard.

  • When creating an application, a productAPI and MapsAPI will be created automatically.
  • Our MapsApi dashboard has been changed to be more efficient for managing applications.

Release December 2019

New Feature
  • Intersect Data API CALL

gis/intersection: Compares two geometries and returns the geometry of where they overlap.

It is now possible to have an Outline Editor without Authentication when not working with oAuth. When creating an application you get the option to enabled it. To toggle this option, edit your application through ‘Algemeen en beveiliging’ -> ‘Applicatitie bewerken’ and choose for ‘Dossiergrens bewerken toestaan voor anonieme gebruiker’. This option is only available in the dashboard.

Release November 2019

New Features
  • auto save outline editor

Every change you make will automatically be saved.

  • Download outline geometry from dashboard.

You can export the outline geometry in geojson, gml and EWKT formats for use in GIS or CAD applications

  • BGT (Basisregistratie Grootschalige Topografie) base layer

an extensive layer with roads, buildings, tunnels, bridges and waterways. Due to it’s complexity and size this layer is visible on a lower zoom-level

  • Bestemmingsplannen base layer

For visual reference we added the bestemmingsplannen layer as a default base layer.

  • 2 new Data API calls for managing geometries.

gis/area: Get area in meters squared for an obtained geometry

gis/buffer: Expand or contract a geometry for more accurate use of the Data API

  • viewer optimisation mobile.

Screen space is limited on mobile, therefore our layers and map information is now available in the roll-up overlay. Click on the map or on the layer-switcher to access the information or switch layers.

  • transparency slider

If you have selected a layer to have transparency, then the transparency slider will be available in the layer switcher.

  • Extensive improvements outline editor. See Outline Editor for full details
  • New Icons. We have updated the icons in all of our viewers and editors. Every function and tool has it’s own unique

icon improving the user experience of our viewers and editors.

  • Loading/save indicator. The old indicators have also been upgraded. The loading indicator is now a spinning compass.

The save indicator is no longer a small green check but is now front and center

  • Highlighting outline (Dossiergrens)

An eye icon is now available besides the outline information after a click on the map. Click the eye icon to highlight the outline.

Outline Editor

The Outline editor (Dossiergrens Editor) has had a complete overhaul. We have minimized the amount of buttons available on start. Giving you the click (select perceel) tool and nothing more. The more advance drawing tools are still available. Just click or tap the ‘down arrows’ to access them.

A new help system has also been made available. You start with a notice giving bullet-point instructions to help you get started. A new i-button is available. Press this button to activate the help-function. Now when you select a tool a short instruction on usage and functionality will appear on screen. Enough of the help? Just click the i-button again to toggle off the help.

First click zoom. You start with the click tool selected and either on national level (seeing the entire country) or on the level of the existing outline. Now when you click, the editor will automatically zoom in and focus on that click. It will do this only once to get you started.

Auto save. Every (de-)selection you make is automatically saved, ensuring your work is not lost in case of a browser crash or other events that would result in the lost of the outline. The old save button is still there if you want to be absolutely sure your work was saved.

The editor has been optimized for mobile. Where it used to be nearly impossible to edit an outline on a phone or tablet, it is now possible to do it with one hand. The tool-bar is conveniently placed in the right lower corner so that all drawing tools can be accessed with the thumb.

Release October 2019

  • The correct Content-Type header is now used with snapshot
New Features

In the Maps API dashboard the option is created to select the layer from an external WMS/WFS/WMTS.

  • Added transparency to MapsApi. It is now possible to have transparency as a setting per layer.

If one layer has a transparency setting, a slider will appear in the viewer.

Release September 2019

  • MapsAPI : After viewer duplication, the outline (Dossiergrens) of the duplicated viewer now uses the correct styling.
  • ProductAPI: While creating a Product API application, ‘slottekst’ can now be empty

Release August 2019


Release July 2019

  • Outline as layer

The Outline (Dossiergrens) is now displayed as a layer in the viewer. The benefits of this is that it can be treated as a regular layer. The layer can be turned on/off. The layer can be sorted. The layer can be printed to pdf.

The outline now gives you the surface measurements in meters squared when clicked.


Existing viewers have automatically been updated to the new standard. We are not expecting this to have any issues, and although thoroughly tested, it could be that you may encounter an issue. Should this be the case than please contact us.

Viewers that are automatically created by API calls should not be affected by this change.

Data API
  • With this release we are also launching our Data Api. You will be able to access our data directly with an address, perceel or geometry. You can daisy-chain several calls together to enrich you viewer or you own database. - additionally we are launching our webhook. In the future long process will be making use of the webhook, moving the proccesses to the background to ensuring a smooth, fast interaction. The webhook also makes it possible to be more responsive with the viewer/editors of maps-api. For now this functionality is available for the outline-editor (dossiergrens editor). When someone saves an outline geometry a webhook call can be placed notifying your site/app of the change. You can use this information to in combination of both Maps & Data Api to gather the necessary data and geometries.
  • If you want to start using our Data Api please contact us.
