Select the project you wish to use.


If you prefer to create an area select the Create a frame option and a frame area will appear on your screen.

To move the frame select the box in the middle of the frame and drag into position. To reduce or enlarge the frame area select a box in the corner of the frame and drag to the desired size.


Next select your Intersect setting. This can either be Whole features (whole features that are intersected by your project area will be included) or Cut features (cut features will cut features that expand beyond your defined project area).

The price for your data purchase will be displayed and to proceed click on Buy Now.

A pop up will appear to confirm the purchase and from here you can Cancel or Buy Now.

Your data will then be added to your map and you can either navigate to your map or to your Data Purchase page.

In your map you will now see your data purchase as two projects, one with all of your features ("OSMM Area") and that other with your labels ("OSMM Labels").
