Historic Download has been updated to use the same interface as all the other collections, making it possible to take maps from different series and scales in a single order.

Historic Download Interface

The new interface is much quicker and easier to use to get all the data you need and will be familiar to users who have taken data from the other Digimap Collections. Unlike the old Historic Downloader you select whether you want the Original Map Sheets or the data cut into squares based on the modern National Grid Tiles at the end of the process once your selections are in the basket.

New_Historic_BasketYou can add products from multiple series, scales or revisions to a single order and you can see where the data is present by using the Availability Overlays.

New_Historic_AvailabilityThe old interface will be retained until the 8th of October to allow time for any course materials to be updated.

EDINA has updated Geology Roam with a whole range of new data, allowing users access to nearly all the data available from Geology Download without needing to put it into GIS software. We have also updated the Active legend, so you can now order it by the Age of the Rocks on the map.

New Data

geology_roam_2015_2

As you can see in the image above the most zoomed out levels now have the Offshore Geology data (DigRock250 and DigSBS250) allowing you to see the rocks and sea bed sediments around the coast of the United kingdom. We have also added in the most detailed onshore geological mapping from the British Geological Survey, the 1:10,000 and 1:25,000 scale maps (DiGMapGB-10 and DiGMapGB25).  Please note that these datasets do not have national coverage, where they are not present there is a water mark on the map to inform you. As there is almost no overlap between these two large scale datasets EDINA has combined them into a single detailed geology layer.

Basemaps

geology_basemapsTo allow different datasets to be viewed at the same scale we have introduced the basemaps tab so that the geology data can be switched with the scale remaining the same. Adding the basemaps tab has also allowed us to introduce new ways of viewing the same data, with all the geology layers now viewable as both the Rock Unit e.g. Kimmeridge Clay Formation and Rock Type e.g. Mudstone.

geology_roam_2015_basemaps

The basemaps tab has allowed many datasets to be view at the same scale so in addition to the new geological data we have also added several extra types of data which provide information about the soil and hydrogeology of Great Britain. The Geological Indicators of Flooding; Permeability (Max and Min); 1:625,000 Scale Hydrogeology; along with  Soil Strength, Texture and Calcium Carbonate content from the Soil Parent Material Data are now all available as basemaps.

Active Legend

Click image to enlarge…

The final change made to the Geology Roam interface has been to the Active Legends which now allow you to order the entries by their age. The ordering is based on the MAX_INDEX attribute in the geology data that allows you to order the Rock Units based on its oldest age.

The active legend still lets you rocks on the map by clicking on the legend and vice versa.

 

A full list of the products available in each view / scale can be found in the Geology Roam “How To Guide” here:

University of Greenwich Queen Anne Court

University of Greenwich Queen Anne Court

For this year’s GeoForum we were lucky enough to be in the Old Royal Naval College at Greenwich, now home to the University of Greenwich. Around 60 delegates enjoyed a programme of talks and presentations aimed at keeping them up-to-date with the maps and mapping technology available to higher education.

The day began with Professor David Maguire, Jisc Chair, Vice principle of the University of Greenwich, former chief scientist at Esri and an acknowledged expert in computer mapping, outlining his vision of the future of  both Jisc and Geographic information science. There was emphasis in his talk about the need to incorporate the Cloud in both Jisc’s services and into the Geographic Data and software services.


Cartographic Design Principles

The first full presentation of the day came from Christopher Wesson, one of the founding members of Ordnance Survey’s digital Cartographic Design team.

Cartographic Design Principles – Christopher Wesson

Christopher gave some background about Ordnance Survey and the data they are now creating.  He then took us through eight key principles that used to create successful cartographic designs: User Requirements, Display Format, Visual Hierarchy, Simplicity, Legibility, Consistency, Accessibility and Good Composition.


Building a 3D Model

The Next presentation came from Jason Taylor, a technical tutor at Ravensbourne responsible for the production of physical models and prototypes. Jason took everyone through the step by step process of taking terrain data along with building foot prints and heights to create scale models of cityscapes.

Creating Physical Models with Digimap Data – Jason Taylor

The result of his work combined milling of MDF particle board and also 3D Printing of a miniature Millennium Dome.  Nearly all of the data used in the production of the model came from Digimap (the details of the Dome’s shape came from a different source), and Jason highlighted the help pages as a great resource for helping him and his students begin to create their models.


The Ordnance Survey Licence

Emma Diffley, EDINA Geoservices Support team leader, then took the audience through the major changes made to the Digimap Licence for Ordnance Survey data.

Digimap Copyright and Terms of use – Emma Difley

This important presentation highlighted the main differences between this agreement and the one it replaced, showing that it is more permissive than before, and that there is now an End User Licence Agreement (EULA) which places emphasis on the individuals to ensure they are abiding by the terms and conditions.

Lunch

During the Lunch break we had presentations from Esri‘s Addy Pope about the ArcGIS Online service; from the CadCorp team who highlighted their free GIS data viewer, MapExpress, and their discounts for educational use; and finally from the British Geological Survey who highlighted their subsurface data and Groundhog website.


Digimap Update

After lunch the delegates were split into two groups with half doing the excursion while the other half was updated on the latest work going on with Digimap and the other Geoservices run by EDINA.

Guy McGarva, EDINA Geoservices Support, gave the Digimap Update presentation highlighting the past year’s achievements and the plans for the coming year. Much of the coming improvements are to do with improving access to the service for mobile devices and also to the data for CAD users.  There are also a lot of new products and cartographic improvements to old products going into the Roam online mapping interfaces.

Digimap Update – Guy McGarva

Guy also highlighted some future trends including better integration between services and a shift to delivering more training through interactive webinars rather than face-to-face training.


Fieldtrip GB

During the Fieldtrip GB excursion Ian Holmes, EDINA Geoservices Support, took the delegates through the process of designing a data collection form, deploying it to the groups mobile phones, collecting data points from around the Greenwich campus and then uploading the data and viewing it on a map.  The entire process was carried out live for each group with the minimum of fuss, highlighting the mobile app’s usefulness for carrying out citizen science or group fieldwork.

Fieltrip GB – Ian Holmes

We also found out about a few of the enhancements coming to the app, including:

  • more stable data management
  • the ability to longer and more complicated multi-page data entry forms
  • an entirely new version with OpenStreetMap data for use worldwide
  • the ability to upload your own maps or way-points to highlight where to collect data

Final Summary

geoforum15_signWe’d like to thank all the speakers and delegates at this years conference for taking part in a very successful event.

All the presentations throughout the day highlighted the changes in the world of digital mapping occurring right now.  We hope that the changes highlighted in the Digimap Update presentation along with the rest of the planned at EDINA will mean the Digimap will continue to be relevant for it users and help them prepare for future work with maps and digital data.

Finally we’d also like to thank the University of Greenwich for providing a first class venue and event coordination team to ensure it was a memorable day.

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

Ceremonial Counties

OS Boundary-Line Ceremonial CountiesThis 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

OS Boundary-Line Historical CountiesThe 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 mapping  from the National Archives  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:

Selecting Layers from Data Download

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:

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 in 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
OS MasterMap Sites Layer

MasterMap Sites Layer includes access points, such as pedestrian gates and driveways, and routing points allowing the data to be fully integrated with other OS products including MasterMap Topography Layer and MasterMap Integrated Transport Network (ITN) layer. 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, into common GIS packages in their Sites Layer Getting Started Guide.

3D Building Heights in ArcGIS

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

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.

3D Buildings in ArcGIS

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.

We have added the Feature Information tool to Environment Roam.  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.  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.  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:

09-04-2015 featureinfoENVYou 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.  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.  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.  For this reason, we can’t operate the Feature Information tool on the 1930s Dudley Stamp maps.  These maps were hand coloured, often by different people using different equipment, therefore the digital versions of  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.

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.

Environment Roam Basemaps TabTwo 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.
