We are pleased to announce the addition of two new datasets to the Digimap Ordnance Survey Collection, which are available to download through the Data Download application. Both these datasets are detailed network datasets and form part of the OS MasterMap family of products. The datasets should prove useful for individuals carrying out detailed network analysis using the road and river network of Great Britain.

OS MasterMap Highways Network

OS MasterMap Highways Network is a new dataset from Ordnance Survey which provides the most detailed road network dataset available for Great Britain. The new Highways Network product is a replacement for OS MasterMap Integrated Transport Network (ITN), which will be retired at some point in the future. Highways Network was built using ITN as the base network and then further improved adding information from other authoritative sources including the National Street Gazetteer (NSG) and local authorities in England and Wales.

OS MasterMap Highways Network with OS MasterMap Topography Layer

Highways Network is provided in GML format as a single, national dataset covering the whole of Great Britain. This is a large dataset and is available through Digimap as a single download of 1.1GB in size.

Ordnance Survey have produced a number of supporting documents that are available for download directly from their website. We recommend that you consult these before using the data.

Current version: June 2016

OS MasterMap Water Network Layer

OS MasterMap Water Network Layer is a new network dataset from Ordnance Survey that represenets the centrelines of watercourses including flow direction and suplementary information.

OS MasterMap Water Network Layer is provided in GML format in 5 x 5km tiles. Water network features that cross tile boundaries are included in all tiles that they cross, so the data is called ‘hairy data’ due to the presence of these ‘hairs’ around the edge of each tile. This means that some processing is required to de-duplicate the features that cross tile boundaries if your order contains data from more than one 5 x 5km tile.

OS MasterMap Water Network Layer is projected in the ESPG 7405, which is a British National Grid projection that also includes the Z value using Ordnance Datum Newlyn.

Ordnance Survey have produced a Getting Started Guide which describes the process of importing the Water Network Layer in to common GIS packages.

We have recently added detailed, large scale, contemporary mapping to Ancient Roam allowing users to compare side by side historic mapping with detailed modern mapping.

Large Scale Contemporary Mapping in Ancient Roam

The detailed modern mapping is visible at all zoom levels in both the 1-up and 2-up views. The most detailed mapping uses the new OS OpenMap – Local product, which is the most detailed Open Data product available from Ordnance Survey and can be downloaded through the Digimap Ordnance Survey collection. We further enhanced the most detailed mapping to include the additional features from OS VectorMap District:

  • Contours
  • Spot heights
  • Medical centres
  • Police stations
  • Heritage sites
  • Places of worship

The other products we have added are OS StreetView and OS VectorMap District Raster to provide a comprehensive set of contemporary map data suitable for all zoom levels in Ancient Roam.

We hope you find the new data useful, if you have any questions about the updates 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:

  • Phone: 0131 650 3302

We released a new version of Digimap last week (2nd February) which included a number of improvements to the service. Whilst we try to minimise downtime during releases some users may have noticed some of the new features; in this post we’ll highlight the changes that affect Digimap users.

Chart Roam

By far the biggest change happened in the Marine Collection where the old, somewhat dated, Marine Maps application was replaced with the new Chart Roam application. Chart Roam uses the familiar Roam interface to display hydrographic charts, enabling users to quickly and easily navigate around using the tools they are familiar with from other Roam clients.

New Chart Roam Interface

Updated Roam Measurement ToolsChart Roam displays marine Hydrographic Charts from SeaZone Solutions using the WGS84 Web Mercator projection. As part of the work done to support the display of map data in different projections we added Nautical Miles to the distance measurement tool in Chart Roam. Users can now measure distances in metric (metres and kilometres), imperial (yards and miles) and nautical units; areas measurements can only be made in metric units at present.

Annotations [all Roam clients]

We have made significant improvements behind the scenes to the way annotations are handled in all Roam applications. This work was done to ensure that users uploading annotations with a large number features can style, save and print the data once loaded in to one of the Roam applications. Other notable improvements are detailed below:

  • We have added the ability to load multiple Shapefiles as annotations from a single Zip archive. Previously it was only possible to import a single Shapefile from a Zip archive, and all other Shapefiles were ignored by the import process. Now all Shapefiles in your Zip archive will be added to the map, and they can be of different geometry types e.g. points, lines and polygons.
  • We have improved the printing process so that it is possible to create prints that contain many more annotations.
  • Improvements have been made to remove some of the internal file size and feature number limits when loading, saving and exporting larger annotations. Note there is a 10MB file size limit when importing annotations.
  • Annotations in CSV (comma separate value) format can now be imported using Latitude and Longitude values; previously it was only possible to import CSV annotations in the British National Grid projection.

Ordnance Survey Roam

A number of changes have been made to the Ordnance Survey Roam application, predominantly to rationalise the data available at the different zoom levels:

  • The vector version of VectorMap District (VMD) has been added to OS Roam and is available at the Local View zoom level (approx. 1:19,000) as an alternative map accessed through the Basemaps option:
    VectorMap District Basemap
  • The Local Plus View has been removed and the datasets available in the District and Local Views have been rationalised. Full details of the datasets available in each View can be found on this help page.

Accessing Product Help [all Roam clients]

As well as updating the help pages to cover the changes listed above, we have also changed the Map Information panel in all Roam clients making it easier for users to get help on the particular map product(s) they are currently viewing in the map window.

  • Hyperlinks to help pages for each product have been added to product names in all Roam clients. The screen grab below was taken from Geology Roam where the hyperlink takes the user through to a help page dedicated to the map product currently displayed in the map window (DiGMapGB-50 Rock Unit):

Map Information Product Hyperlinks

Digimap’s new registration system was released on the 28th of January, we hope you’ll agree that it is a huge improvement over the  previous version.

Users no longer have to wait up to 48 hours for registrations to be approved, they simply have to click a link in an email sent to them after filling in the registration form.

It already has its fans leading one site rep to say “I love the new registration system!” and another told us “Congratulations on instant registration for students. This is going to be very popular.”

The new instant access system is much more inline with user expectations from online services.  Removing the need to wait overnight (or longer over weekends) to gain access has been very popular and has resulted in a significant increase in registrations during February.  Over 6000 registrations were processed through the new system at all times of day and night!

We now need your help to make sure that the support material at your institution is up-to-date and that your students know that they can have access to the service the same day.

There is a full description of how to register using the new system in the help pages which guides you through the process:

http://digimap.edina.ac.uk/webhelp/digimapsupport/about.htm#access/registration.htm

If you are responsible for any local support pages, lecture notes, practical guides and any other course material please make sure these get updated. We actively encourage the incorporation of the images and text from the help page in any material produced. Please can you circulate this information as widely as possible to ensure that all users have up to date guidance.

One final plea is that you highlight the importance of entering the correct email address when registering.  This should be an email address that is used regularly and it should be spelt correctly!

In January 2013 the OS MasterMap®, Boundary-Line™ and Code-Point® data products will be available from the Data Download service. We have tried to keep the changes necessary to accommodate these products to a minimum as the current interface has proved so successful (190,000 map tiles and files downloaded Nov 2012).

Here is a list of the changes and additions you will see in the interface; please note that they may still be subject to some change prior to launch.

Both Boundary-Line and MasterMap have layers so we have had to make changes to the basket:Digimap Data Download Basket

Instead of selecting Version and Format using drop-down menus there is a new pop-up for changing both these and the layers for each of the products in your basket. You can access this pop-up by clicking on the Change link in the Options column:

Digimap Data Download Basket Options

We have also improved the “My Account” section which is now called “My Previous Downloads”:

Opening "My Previous Downloads"Once in the interface you can access any of your past downloads and reopen them at the basket stage:

Digimap Data Download My Previous Downloads

It is now much easier to update your previous downloads to the latest version, get the same data in a different format or simply reorder data you have previously taken. In addition to these functions we have incorporated the ability to make Change-Only-Updates (COUs) to MasterMap Data:

Digimap Data Download Change Only Update

Both Boundary Download and MasterMap Download will be kept in service for a transition period but as there are so many benefits to using Data Download we hope everyone will make the switch quickly. We expect to have switched off these services by the end of April.

Service "At Risk".Some of the features mentioned in the previous blog post will be added into the services tomorrow, Tuesday 28th June:

More Improvements Coming Soon

Due to this work there will be some short Disruptions to all the services between 17:30 and 18:30. We hope you find the new features useful, please let us know if you have any feedback:

We have had another very busy month and so a new batch of improvements for the Digimap services will be coming soon.

Printing in Ancient Roam

At the moment downloading data or saving screen images are the only ways to use the maps available in Historic Digimap once you have logged out.  Soon you will be able to create and save high quality PDF maps from Ancient Roam for use offline. We hope you will find this a much better way to get the best quality mapping out of the service.

A sample image of what a PDF from Ancient Roam may look like.

New Data in Digimap Roam

Since the arrival of the Ordnance Survey’s latest large scale product, VectorMap Local,  we have been busy thinking of the best way to include it in the Digimap Roam. We have decided to use it to create four new representations available at two different scale levels.

Here is a quick look at what the four different representations might look like:

VML standard

Vectormap Local- Standard

VML Streetview

Vectormap Local - Streetview

VML Plan

Vectormap Local - Plan

VML Raster10k

Vectormap Local - 1:10,000 Raster

We haven’t stopped there either; we are also going to add in Line Drawing style mapping to the two most zoomed in levels; for those who like their MasterMap plain and simple, similar to planning application maps.

MasterMap - Plan

MasterMap - Line Drawing

You will be able to select the different views from the Map Content Control Tab using a drop down list.Alternate representations choice Menu

For more information about VectorMap Local look in the Digimap help pages as it is already available for download:

Annotation Tools in Geology Roam

For those of you who have tried the annotation tools in Digimap Roam it will come as no surprise that we are very pleased to announce that we are now working on adding the same functionality in Geology Roam. Again the annotation tools are a first draft and will have exactly the same functionality as Digimap Roam’s tools.

Geology Annotation Tools

Once they are released we’d really like to hear from you about which functions you use and what else you would like added. We are already hoping to add in some Geology Mapping symbols for you to add to the maps.

As an added bonus we are also putting in the measurement tools so you can measure areas and distances too, so you can tell how long a fault is or what area is covered by different rock types.

We have been having a play around with the new annotation tools in Digimap Roam here at EDINA, and have come up with a few things you might like to try.

Firstly, you will have no doubt been adding many new features to maps but have you tried taking some away?

A farm shown in Digimap Roam

This is the original map area, a MasterMap map showing some large farm buildings to the left of the original farm house. If you had some information about how the area looked prior to their construction you could recreate a map form the past.

The map on the right shows the area after a large green polygon has been drawn over the building area.  Make sure you select an appropriate line width and style for the map, and remember to set the opacity to maximum. You needn’t stop there though, you could add buildings on top of the green polygon representing those that had existed previously.

 

You can also use the annotation tools for some other neat tricks.  The image below shows how you can trace around existing features, a car park in this case, and use the measurement tool to work out its area. By making the polygon fully transparent you can then print out your result without obscuring the original features.

Finally you can use multiple lines and polygons, annotated with text to build up complex new features on the map. The example below shows a proposed new airport in the Thames Estuary:
