Base Program - Constraints Maps

Free Drag & Drop national mapping constraints to enhance and support your Planning Application. Portable Mapper ’s Ecology & BS5837 Tree Survey program raises the bar yet again with this simple timesaving approach. There will inevitably be some form of external restriction or constraint attached to the site area you are surveying or have under development. Prudence dictates we factor in and show these constraints where applicable. Portable Mapper have started pulling together some of the more common constraints for you and they can be found in our Download area

Why include constraints on a map ?

Just occasionally you'll find yourself working either in or on the fringes of one of these constraint areas. And you need to know exactly where the boundary lies for many reasons. Likewise when it comes to printing no plan or drawing would be complete with something this important omitted.

Portable Mapper have pulled together all the latest UK constraints for you in to one simple drag and drop file. And best of all they are free. Just login to the Download area. No catch. No adverts. No popups.

Some might say 'well I can get all this information myself because it's freely available'. This is true but if you're busy then maybe you don't have the time. Portable Mapper have done this for you so you don't have to.

How reliable are these datasets ? All have either been downloaded from the national bodies that create the data or from the government's own data download site. Within your downloaded files you'll find a text file telling you the source and the date it was last updated.

Are there any restrictions using this data ? All datasets are subject to the OGL (Open Government License) which allows you to adapt, use, copy and print as you wish without any cost or restrictions so long as we include the attribution; 'Contains public sector information licensed under the Open Government Licence v3.0 ' somewhere.

Interrogating the data. These datasets show every individual constraint. Some may only be a few meters across, some may be thousands of meters. Each one has its own attributable data and that data can be viewed and interrogated using Portable Mapper's standard tools.
