The following table represents the absolute and relative accuracy applicable to the scale at which the product is surveyed.
RMSE (Root mean squared error) is the square root of the mean of the squares of the errors between the observations.
Our Mastermap formats are DWG, DXF, PDF, PNG and GML. All other mapping and aerial photographs are in PNG format.
Our scale range varies from 1:200 to 1:10000 depending on the map type requested.
We offer a range of digital maps and geospatial information for professionals, such as architects, surveyors amongst many others. A popular map is called Mastermap, which is one of the most detailed mapping available and surveyed by the Ordnance Survey. We offer it in CAD formats like DWG and DXF but also PDF and PNG. We also offer a range of optional extra layers such as contours, freehold boundaries, building heights and aerial photography. Read more about our full mapping range here: Map Types
The location plan is typically 1:1250 or 1:2500 for larger sites and the site/block plan is typically 1:200 or 1:500. You can check the following link for more info: Guidance for Planning Applications
It is possible that your property is not registered, or it is situated out of the borders of the map. Please note that the map is updated every few months so make sure to check regularly. Also, please, make sure you use the correct address or coordinates when looking for your property. Our maps are surveyed by the Ordnance Survey so if you think there is an issue please contact them directly.
If you’re a member of the public, we offer planning maps via our site Buyaplan, which may be your fastest option.
Mastermap and many of the smaller scale maps are updated by the Ordnance Survey every 6 weeks, however it can take longer than that for new objects to be surveyed and added to the mapping. We then immediately update our site. If you feel the mapping is out of date please contact the Ordnance Survey directly.
Yes, our plans feature a north arrow and scale.
If your main priority is saving money and you use mapping in large volumes then going for the ‘MapServe™ Professional’ account may be the best option. The ‘MapServe™ Pay-As-You-Go’ may suit lower volume ad hoc use. See the Price List for a more detailed comparison.
OS MasterMap is the most detailed and accurate digital map of Great Britain, surveyed by the Ordnance Survey. It features every fixed feature of the land, man made or physical, that is larger than a few metres. It is updated continuously and we offer it in CAD and raster formats like PNG and PDF.
A reference is the name of the map that appears on the invoice. Usually, the address that you choose is automatically added as the reference of the map but you can change this if you want. It is situated on the top left corner of the website.
The optional extra layers we offer are 1m contours, building heights, freehold boundaries, listed buildings and the National Tree Map, see more detail here Map Types. These are CAD format only.
The software you need depends on the format of the map. DWG and DXF files require CAD software (free viewer here Autodesk Viewer). PDF requires an Adobe Acrobat Reader (free viewer here Adobe Reader) and GML files require GIS software or similar.
You can order and download the mapping within minutes, 24 hours a day.
Yes you can. In addition to our standard 'Pay as you go' option, we offer a 'Professional' account which gives you further discounted mapping, more free Mastermap previews and 30 days credit. You can pay via direct debit, on a card or invoice. There is an annual charge for this facility with details shown here Price List.
Interested in a 'Professional' account? Then contact us.
We offer two versions of Mastermap in CAD format. One is the ‘Standard’ version where there are up to 20 different layers of data while on the ‘Pro’ version there are up to 67 individual layers of geographical information. The ‘Pro’ option also features filtering options to help group the layers together or select the ones you would like to use each time e.g. all historic feature layers. You can do that in your CAD software.
There may be a number of possible reasons for this. You may have ordered a map in CAD format (DWG or DXF) and do not have CAD software. If you've done this by accident, no problem, contact us and we can convert it to a format like PDF that can be viewed on most computers. If you're using AutoCAD or similar, there may be a 'Zoom to Extents' button which may then show the mapping. If you still can't see the map and have CAD software, a good test is to upload your DWG or DXF file to this free Autodesk Viewer) to check if the map file is okay. If it isn't, please contact us.
When you place an order you get a link where you can download your mapping from and this is also e-mailed to you.
Maps are only scaled once they are printed out. To obtain a map of a certain scale, select the ‘Paper Size’ button and choose the scale that you need and the paper size. Finally select the map type that you need and remember that OS MasterMap is the most detailed mapping and is the only one suitable for planning applications. For CAD format maps, the scaling can be set within the software.
You will need to use software you’re using to view the map. That will either be CAD software for DWG and DXF format maps or software that can open PDF or PNG if you’ve ordered this format.
If you’ve downloaded a PDF, check your printer to ensure it’s set to print at 100% scale. If it is then scaling issues will be down to the original mapping provided by the Ordnance Survey. Please contact them directly about this as we cannot edit the maps. For CAD format maps, the scaling can be set within the software.
We can refund the order however we may deduct a 30% fee to cover the Ordnance Survey royalty charges and administration costs. It is important to check before ordering that the correct area, map type and licencing is selected.
Check that you have the latest Adobe Reader or similar viewer installed. If not you can click on the following link and download it for free Adobe Reader.
Check that you have CAD software installed. You can download a free viewer here Autodesk Viewer.
The link is valid for 12 months from the day of purchase. If you need the download link for more than that please contact us.
No, it is not possible to make changes to the map after purchase. If a mistake has been made you can place a new order and we can refund you the original, but we may deduct a 30% fee to cover royalty charges and administration costs. It is important to check before ordering that the correct area, map type and licencing is selected.
The site will only deliver the plan and any red / blue lines you've added and previewed on the site. To add a line to the plan (red or blue) you need to click on the colour button you want and then move to the map and click to outline whatever property you want. You'll see the property will be outlined in the red or blue lines if you've done this correctly. If you reorder, we can then refund your plan minus 30% to cover costs we incur.
The plan should cover an entire sheet of A4 if printed at 100% size. The map portion however is only a portion of this otherwise the scale would not be correct. We also need to display copyright information, location and licence details.
Our maps in CAD format come in layers with each type of geographical information seperated for ease of formatting. We’ve used obvious layer names so you can understand what each layer represents. Additionally, if you’ve ordered an optional extra layer like ‘1m contours’, the order email will detail the layer names.
