In today’s architecture, 3D conceptual modelling is fast becoming an essential tool to help you to accurately map out your project and provide detailed plans for your clients.

These datasets include OS height data and OS Terrain 5, to provide a 3D visual representation of your site with detailed landscapes, terrain, topography, contours and spot heights, without having to open a CAD or GIS program. The file formats come in both PDF and DWG and are delivered as a single .zip file. OS building height data is in its alpha release, featuring approximately 20 million buildings in England and Wales.

How do I order a report?

If you already have a Groundsure account you will need to log in using your user name and password and select the product(s) you require. If you do not have a Groundsure account, one must be set up, even for single pay as you go orders. This can be done using the create an account function.

What does 'Order in Progress' mean?

Order in progress is a status we assign when your report or data is being produced. You will receive your product within the defined turnaround time. If you order states “with Groundsure”, this is because you have submitted your order with a site plan and we are working on digitising your site boundary, or because the site drawn exceeds our standard pricing options. Orders will be placed within 24 hours, and a member of the team will be in contact if we require further information. If you order states “On Hold”, this is because one of our environmental consultants has raised a query with your order. This query will have been emailed to you.

How do I download a report?

All reports will be delivered by email to the designated email address. If necessary, you are also able to include an additional email address before placing your order. However, if the file is too big for email, a download link will be emailed to you. Alternatively, you can download any report from your Order History.
