OS Open Map – Local (OML) was recently added to the Digimap Roam application, giving users the ability to create maps online with a detailed, vector open dataset. OML is the most detailed vector mapping product available from Ordnance Survey as Open Data. We have added this dataset to the following map views in Digimap Roam:

Map View Default Print Scale
Neighbourhood View 1:10,000
Street View 1:5,000
Detailed View 1:2,500

The dataset is rich in features and includes detailed building outlines and Car Charging Points, which are sourced from the National Charge Registry.

Ordnance Survey first released OML as a beta product in March 2015 and Digimap users have been able to download this dataset via the Data Download application since April 2015. The October 2016 release of OML marks the end of the beta period and provides the first main version of the dataset.

OML is intended to be used as a detailed basemap on which to visualise your own data and is designed to be an alternative to OS Street View, which will be withdrawn in March 2017 by Ordnance Survey.

The cartography team at Digimap have worked hard to implement a consistent style with that of the smaller scale VectorMap District product, ensuring a familiar look and feel between the two Open Data products. Contours from the OS Terrain 50 product are included when viewing the data in Roam, to give greater context especially in rural and hilly areas.

Further information on the new dataset can be found on the Digimap help page or the Ordnance Survey website. We hope you like the new data, if you have any questions about the dataset or Digimap please contact us:

Last week (3rd March) we released a new version of Digimap which includes a number of changes that may be of interest to our growing user base. Our set-up allows us to release new versions without requiring any downtime so the recent changes are highlighted below as they may not be obvious at first glance.

Greyscale versions of the 1:25,000 Colour Raster and 1:50,000 Colour Raster have been added to OS Roam

We have added greyscale versions of the 1:25,000 Colour Raster and 1:50,000 Colour Raster products in the Roam client of the Ordnance Survey Collection. These can be selected using the Basemaps drop-down.

Greyscale 1:25,000 Colour Raster with annotations

The new greyscale versions make it much easier to see your annotations on top of the basemap. The greyscale versions can be saved and printed like all other basemaps available in OS Roam.

Warning about losing changes in all Roam clients

If you customise a map in one of the Roam clients, for example by modifying the layers that are displayed or by creating annotations on the map, then press the browsers back button or navigate away from Roam you will now see a warning prompt advising you that you may lose your changes. The prompt that is displayed in Chrome is shown below:

Confirm navigation

The prompt is not displayed if you have saved the map, printed the map, or exported the annotations.

Updates to the Open/Save wording in all Roam clients

We have updated the text on the Open and Save menus in all Roam clients to make it clearer what each option does:

Roam Open drop down

Open > Saved maps allows you to open any maps you have previously created and saved within Roam.

Open > Import annotations is where you go to import external datasets in to Roam (we currently support the import of datasets in Shapefile, KML, GPX, CSV, and GeoJSON formats).

 

Roam Save drop down

Save > Save map will save the current map extents along with any annotations to Digimap for retrieval at a later date.

Save > Export annotations allows you to export annotations from Roam as an external dataset for use GIS/CAD (we currently support the export of datasets in Shapefile, KML, and GeoJSON formats).

 

Background mapping in Data Download of all Collections is now shown in greyscale

The background mapping data in all Data Download clients has been converted to greyscale:

OS Data Download

This makes it much easier to see the availability and reference grids in these applications.

Further improvements

We hope you enjoy using these new features. We are continually improving the service so if you have any suggestions for improvements to the service please get in touch:

We are pleased to announce the release of DWG versions of both OS Terrain™ 5 (vector) and OS MasterMap® Topography Layer Building Height Attribute, which makes their use in CAD applications much easier and quicker.

Recently we have been working to produce DWG versions of the detailed vector dataset OS Terrain™ 5 and the popular Building Height Attribute component of OS MasterMap® Topography Layer. Both these datasets have proved popular with CAD users for detailed modelling applications but until now using them has proved time-consuming as many steps were required to convert them in to a format suitable for use in CAD applications.

OS Terrain 5 Vector

OS Terrain 5 Vector is dataset consisting of contour lines with five metre vertical spacing and spot heights (point features). The dataset also includes contours for mean high and low water around coastal areas, along with labels for both spot heights and contours.  OS Terrain 5 is the most detailed height dataset available from Ordnance Survey. A Digital Terrain Model (DTM) version is also available in ASCII grid format and can be downloaded through Digimap.

Building Height Attribute (BHA)

As with the other BHA datasets provided through Digimap the DWG version is supplied as a dataset of building polygons together with the building height attributes supplied by OS in the latest alpha release of their Building Height Attribute dataset (December 2014 at the time of writing). The DWG dataset is a 3D dataset which uses two of the height attributes supplied by OS to create the 3D features.  The base height of buildings is set using the value of the AbsHMin attribute and the roof height is defined by the AbsH2 attribute:

BHA Attributes

All height attributes supplied by OS, as indicated in the image above, are included as XDATA which can be readily viewed in CAD applications.

Note: the DWG BHA dataset is not supplied with a terrain surface so the building features will appear to float above the surface if it is displayed without a suitable terrain surface. We recommend using either OS Terrain 5 or OS Terrain 50, both of which can be downloaded from Digimap.

The image below shows OS Terrain 5 vector overlaid with BHA in AutoCAD 2015 for the area around Edinburgh Castle. Both datasets were supplied by Digimap in DWG format and required no manipulation or processing in order to display them.

OS Terrain 5 with Building Height Attribute

OS Terrain 5 vector and OS MasterMap BHA datasets are supplied on a 5x5km grid, so you may receive multiple multiple files if your area covers more than one 5km grid square.

We hope this makes it much easier to use the data and we welcome any feedback you may have.

Of particular note at this time is that Ordnance Survey have announced the withdrawal of the 1:50 000 Scale Gazetteer and OS Locator products following the release of OS Open Names in March 2015.

  • The last product update for 1:50 000 Scale Gazetteer will be June 2016.
  • The last product update for OS Locator will be May 2016

Following these releases Ordnance Survey will no longer supply, maintain or support the use of either OS Locator or 1:50 000 Scale Gazetteer.
