Chart Roam to replace Marine Maps

Posted on December 1, 2015 by ecls

In January 2016, the Marine Maps application available through Marine Digimap will be replaced by a new application called Chart Roam.

As it’s name suggests, the new application will offer the same Chart data currently available through Marine Maps.Â SeaZone (the data supplier) now call this dataset HydroView Charts.Â They were previously referred to as the Charted Raster data.

Chart Roam will operate in the same way as all other Roam clients available, offering slippy maps, 12 fixed scale map views, annotation and measurement tools, as well printing in multiple file formats and sizes up to A0.

A date for release will be advertised in the new year.

If you have any questions, please do not hesitate to contact EDINA on edina@ed.ac.uk.

Old Historic Download withdrawn Friday 11th December

Posted on December 1, 2015 by Tom Armitage

Old Historic Download

EDINA will be withdrawing the old Historic Download on Friday the 11th of December.Â With most people now using the new Historic Download we have taken the decision to switch off the old version to free up resources. The new interface contains all the same data but allows you to take multiple products and revisions in a single order. Existing users’ Download History from the old interface will NOT be available to reorder from the new interface so please make sure you have made all the necessary orders in the old interface before the 11th.

New Historic Download

Please note that if you want a definitive list of published dates for the maps you download from the new interface, it is available in the contents.txt file delivered in your zip folder with your data. This text file has the details for every tile / sheet of map data you have taken.

The old Historic Download was the last remaining download interface that was different to the other collections, so now every collection uses the same interface to retrieve data for use in CAD or GIS software.

OS MasterMap Topography Layer now available in outline ‘plan’ style for CAD users

Posted on October 21, 2015 by Ian Holmes

In April 2015Â we madeÂ OS MasterMap Topography Layer data available to CAD users in DWG format. If you missed the announcement you can read all about it in this blog post. Since adding this optionÂ to DigimapÂ we haveÂ processed over 13,000Â orders for MasterMap in DWG format. Building on this we have now produced an outline ‘Plan’ style of MasterMap in DWG format which is a stripped down representation that mimics the alternative ‘Line Drawing’ style of MasterMap available in the Digimap Roam application.

OS MasterMap Topography Layer in standard and plan style

The alternative ‘Plan’ style is a cut down version of the full dataset andÂ does not include polygons, users requiring the full dataset should download the original ‘Standard’ style which includes both lines and polygons.

The style is specified in the basket window of the Data Download application using the drop-down in the ‘Theme’ column:

Selecting DWG plan style in the basket

We hope you find this new styleÂ useful, if you have any questions or suggestions for further improvementsÂ please contact us:

Boundary-Line updated with different County Boundaries

Posted on May 29, 2015 by Tom Armitage

The latest version of Ordnance Survey’s Boundary-Line data contains two new layers,Â Ceremonial Counties and Historical Counties.

Ceremonial Counties

This new layer in the Boundary-Line data represents the areas of England, Scotland and Wales that are represented by a Lord Lieutenant. The Lord Lieutenant is the chief officer of the county and representative of the Crown; whenever the Queen visits an area she will be accompanied by the Lord Lieutenant.

This layer is very useful for those who want to make a map of Great Britain divided into its counties without all the complexities of Unitary Authorities, Districts and Boroughs. This is the layer to choose when making a map showing a more traditional view of Great Britain without making a historical view.

Historical Counties

The historic counties dataset shows the county boundaries in place in 1888 in England and Wales and 1899 in Scotland. The boundaries for England and Wales were derived from mappingÂ from the National ArchivesÂ dating from 1890. The Scottish boundaries are derived from maps as late as 1940.

This layer is very useful for those studying this time period and when combined with the ceremonial counties and modern the most up to date boundaries gives a good picture of how fluid the boundaries are over time.

Selecting Layers in Data Download

If you have the Boundary-Line data you need already but would like to add the new layers without downloading it all again then follow this useful tip. Once you have added the product to your basket click on the arrow in the layers column to pick and choose those that you want to take. See the image below:

You will then just receive these new layers and not all the others which you may already have or not need.

Please let us know if you have any questions about this or any other aspect of the service:

Points of Interest now available through Ordnance Survey Data Download

Posted on May 21, 2015 by Ian Holmes

Ordnance Survey Points of Interest sample

We are pleased to announce that the Points of Interest dataset from Ordnance Survey is now available to download through the Digimap Data Download application.

Points of Interest is a national dataset covering the whole of Great Britain and contains overÂ 4 million different features. All features are supplied with location, functional information and addresses (where possible). Points of Interest has a three-level classification to assist customers in identifyingÂ the features or sets of features they require. This classification is explained inÂ detail in chapter 3 of the official User Guide. The top level classificationÂ is given below:

Accommodation, eating and drinking
Commercial services
Attractions
Sport and entertainment
Education and health
Public infrastructure
Manufacturing and production
Retail
Transport

Please note: the copyright statement for Points of Interest is slightly different to the usual Digimap statement as the data is licensed from PointX by Ordnance Survey. The correct copyright statement that should be displayed with Points of Interest data is included below:

The data can be found in the Boundary and Location Data section in Data Download:

Points of Interest in Data Download

The data is provided in CSV format (comma separated values). To load this inÂ toÂ GIS forÂ visualisation on a map requires a couple of short steps to create a definition file so that the GIS application uses the correct data types for each field in the file. We have created instructions on how to do this in ArcGIS and QGIS:

OS MasterMap Sites Layer now available in Digimap

Posted on May 13, 2015 by Tom Armitage

Â© Crown Copyright and Database Right 2015. Ordnance Survey (Digimap Licence)

A new MasterMap data layer is available to download that allows you to add an extra level of information to your maps. The Sites Layer shows boundaries for features such as schools, hospitals and other government property. The dataset currently contains the extents of over 40,000 important locations inÂ Great Britain broken down in to seven themes, with more to be added in the future:

Air transport
Education
Medical care
Rail transport
Road transport
Water transport
Utility or industrial

Â© Crown Copyright and Database Right 2015. Ordnance Survey (Digimap Licence)

MasterMap Sites Layer includesÂ access points, such as pedestrian gates and driveways, and routing points allowing the data to beÂ fully integrated with other OS products includingÂ MasterMap Topography Layer and MasterMap Integrated Transport Network (ITN) layer.Â Sites Layer can be used for informed decision-making and spatial analysis, enabling users to answer questions such as: ‘how much of this health centre is at risk of flooding?’.

Ordnance Survey have published clear instructions on how to import the data, which is supplied in GML3 format, in to common GIS packages in their Sites Layer Getting Started Guide.

OS Building Height Attribute now available in file geodatabase format

Posted on May 12, 2015 by Tom Armitage

We are pleased to announce that users can now download OS MasterMap Building Height Attribute data in file geodatabase format. The data consists 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).

This makes the process of visualising the data in 3D much simpler for the majority of GIS users. The file geodatabase format can be read by both QGIS and ArcGIS, including the new ArcGIS Pro, without the need for any complex data processing. Making the data available in file geodatabase format removes the need for users to download building features from OS MasterMap Topography Layer and then use the JOIN function in GIS to connect the Building Height Attribute data to the buildings.

The data is supplied on a 5x5km grid, so you may receive multiple separate geodatabases if your area covers multiple 5km grid cells, however it is easy to merge the datasets together using common GIS functions.

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

Feature Information tool added to Environment Roam

Posted on April 28, 2015 by Tom Armitage

We have added the Feature Information tool to Environment Roam.Â This allows you to select points on the map to identify what the land use is at that location. Some of the colours used on the maps are very similar, which, while necessary with so many different categories, makes the maps more difficult to interpret.Â When the opacity slider is used to see the base map through the colours there can be even less distinction. The feature information tool helps to overcome this difficulty.Â The tool is also vital for those with a colour vision deficiency,

To identify the land use category for a particular point, click on the i button in the bar above the map:

You will notice there is now a little question mark next to your mouse pointer, now click on a location to identify the land use at that point.Â A small red pin will appear on the map along with a box containing the information about the location clicked on:

This feature has been a part of the Historic, Geology and Marine Roam interfaces for some time.Â However, it took much longer to develop this tool for Environment Roam because the data is very different. Rather than querying a database about the location we use colour matching technology to find the corresponding legend entry for the location clicked on.Â For this reason, we can’t operate the Feature Information tool on the 1930s Dudley Stamp maps.Â These maps were hand coloured, often by different people using different equipment, therefore the digital versions ofÂ the colours are inconsistent. Since the Dudley Stamp maps have fewer land use categories there is less confusion in identifying the appropriate colours in the legend, but we recognise that there may still be difficulties for those with colour vision deficiency.

1930s Land Use Maps now in Environment Digimap

Posted on April 17, 2015 by Tom Armitage

We have moved the Dudley Stamp Land Use Survey maps from the Historic Digimap Collection to their more natural home in Environment Roam. In doing so we have increased their usability. You can now pan and zoom much more easily and can print and annotate the maps, something that was not available in the previous Land Use Map Viewer.

Two scales of map are available for all of England, Scotland and Wales: 1:625,000 and 1:63,360.

Environment Roam automatically switches between these at the appropriate point when zooming in or out of the map.

To view the 1930s maps go to the Basemaps selector on the right hand side of Environment Roam and choose Dudley Stamp 1930s from the drop down window.
