Create your site boundary

The site boundary creator tool allows you to place your setting on the Nature Park map.  

This is a computer-based activity for educators to complete, as part of your preparation before getting young people involved in mapping your site. In this short activity, you will draw the boundary of your educational setting directly onto the Nature Park’s map of England.  By completing this task:

  • all the data you collect in the programme will be associated with your setting, allowing you to measure nature gains on your site
  • your setting will be visible on the Nature Park map, as part of the community
  • you will find out the size of your site and this figure will be added to the total size of the Nature Park

You need to be registered and logged in to complete this activity.

  • A computer with internet access

Step by step

Watch our video tutorial below that shows the step-by-step process of creating your site boundary.

  1. Access the site boundary creator tool.
    You can do this using the 'Begin activity' button. 
  2. Find your URN.
    If you don’t already have your setting’s URN to hand, links provided in the first pop-up screen in the tool will help you find it.
  3. Check you are in the right location on the map.  
    When you open the Site Boundary Creator, the map will zoom to your setting location based on the information you provided when you registered. In some cases, the map may zoom to a location a bit further down the road, so make sure you are in the right place before you get started.  You can move around the map like you would in google maps (dragging the screen with your cursor), or use the search button to look for a postcode or address, if you need to correct your location.
  4. Draw a line around the outside boundary of your educational setting’s site.
    In the tool there is a ‘Create features’ section on the right-hand side.  In this section, when you click on “Education Site Boundary” you will be able to place dots along the boundary of your school site (like making a dot-to-dot picture).  The tool will automatically join the dots for you, as you go, creating a shape of the boundary of your site.  
  5. Check and edit your boundary.
    When you have finished drawing the boundary you can then make some changes if you need to. You can move around the dots that you created, move the whole shape across the map, or make the shape bigger, smaller, narrower or wider, just like moving a shape you have drawn in a Word or Powerpoint document.  
  6. Add your educational setting’s URN.
    When you are happy with your boundary, you then need to input your setting’s URN.  This will automatically attach your setting’s name, postcode and phase of education to the shape you have created, based on the information you provided when you registered.  Adding your URN ensures that we can link all the data you collect within this boundary to your educational setting, meaning you can view and measure your nature gains.  If you are a nursery, you must add the letter N in front of your URN e.g. N100100.
  7. Submit your boundary. 
    Confirm that ‘Yes’ your boundary is correct and click ‘Create’ to submit your information.   If your site is divided across more than one location, you can now repeat steps 3-6 for each area of land.
