//Even though we update our mapping data throughout the year we still make a large number of changes over the summer.
Along with the general updates to MasterMap and a few other products the biggest change over the summer has been to swap the 1:10 000 Scale Raster maps to VectorMap Local Raster maps in Digimap Roam. Ordnance Survey have retired the 1:10 000 data, so we have removed it from the online maps, though you do still have a couple of options if you are a fan of the product:
The table below details all of the latest changes we have made showing the currency dates of all Ordnance Survey datasets in Digimap.

Remember there have also been substantial changes made to the Geology and Marine data holdings in recent months:
Please also note that there are a lot more formats available than before so you may not have to convert the data after you have downloaded it:
It is now easier to see which formats are available for the data product you are downloading and change it if you need to, this blog post shows you how:
Please let us know if you have any questions about the new data or any other changes and additions to the Digimap service
//We have now added detailed 1:10,000 and 1:25,000 geological mapping data and 1:625,000 hydrogeological data to Geology Download. The mapping data is the most detailed geological mapping available from the British Geological Survey (BGS), consisting of four polygon layers:
…and one linear features layer, including:
The products cover around 30% of the UK most of the which is provided by the 1:10,000 scale data (approx 28% of the UK), as the coverage is not complete we have added overlays to Geology Download to guide you to the areas where it can be found. The BGS have more map tiles in production for this dataset and we will add them to the service as they become available to us. The coverage of the data can be seen in the Download interface below as the dark blue areas of Great Britain.
The 1:25,000 has a much smaller coverage, but with little overlap with the 1:10,000 it makes a good companion dataset to fill in the gaps. The 1:25,000 data also fills the gaps in the 1:50,000 data in Wales, again the coverage can be seen in the interface below as the dark blue areas.
To access the coverage maps click on the double arrow to open the Show Grid / Overlay panel on the right side of the map; you can then add the grids to the map to see where data is available. We highly recommend you do this before selecting your area for download as it is not possible to add data to your basket if you choose a product with no coverage for your that area. If you find that the Add to Basket button remains grey after you have selected your products it probably means that one or more of them do not have coverage for the area you have chosen. If you click on the grey button an error message will tell you which products are unavailable, either remove these from the order or switch on the overlay and choose a different location that has the data.
In addition to the 1:10,000 and 1:25,000 scale mapping datasets we have also added the BGS OpenData 1:625,000 scale digital hydrogeological data to Geology Download. This data can be used to indicate the aquifer potential of an area in generalised terms. Areas are categorised into one of three groups:
The 1:625 000 scale data may be used as a guide to the aquifers at a regional or national level, but should not be relied on for local information.
The addition of these new datasets brings the total number of different BGS products in Geology Download to 14. We hope to add the detailed mapping datasets to Geology Roam later in the year as well as some of the other types of data as overlays or basemaps.
If you have any questions about the new datasets or any requests for geology data we don’t yet have then please get in touch:
//Marine Digimap has updated datasets in its brand new Marine Download facility. The new interface provides a single place to get both Hydrospatial data and charts. The Hydrospatial data is now the newer Hydrospatial One dataset from SeaZone which also provides access to much higher resolution gridded bathymetry data, one arc second instead of six. The Charted Raster dataset has been replaced with Hydroview Charts; these are still the same scanned Admiralty Charts though they are much more recent and include some small scale charts covering whole oceans (still not for navigation though!).
Marine Download works in the same way as Data Download, Environment Download and Geology Download; you select your area, pick your products and download the data. The main difference is with datasets as these don’t all form continuous coverage of the UK Coastal waters. We have therefore included overlays that show where the tiles of each dataset can be found. These are very useful when choosing your data, just open the “Show Grid / Overlay” menu on the right of the map and pick the overlay for the data you are selecting.
Remember there can be a lot of overlap between the Hydroview Charts and also large areas with no data, you will get all the charts that present for the area and scale band that you choose. If there is no data for the area you have selected then you will not be able to add anything to the basket, if you try you will get an error message informing you of the products with no coverage.
For a full description on how to use the new interface, have a look at the help page: How to use Marine Download
The data in Marine Download is broken into three categories, Hydrospatial, Hydroview Charts and Bathymetry. In the Hydrospatial category the same themes as before can be found, the Hydroview Charts are broken up into categories depending on their scale including those extra charts with wider ocean or global extents.
The old interfaces for downloading data, Hydrospatial Download and Charted Raster Download, will be withdrawn in the coming weeks, if you have teaching materials that include them then please update these as soon as possible.
If you have any questions about the new download or the withdrawal of the old interfaces then please get in touch:

EDINA have added data for Northern Ireland to Environment Digimap after an agreement between Jisc and the Centre for Ecology and Hydrology (CEH) to extend the service beyond Great Britain.
The data comprises of 25m and 1km resolution raster datasets for 2000 and 2007 as well as vector data for both these years. The data shown on the right is the 1KM resolution raster data from 2007.
The datasets essentially classify the land into categories including: sea and inland waters, bare, suburban and urban areas, arable farmland, pastures and meadows, rough grass, grass heaths and moors, bracken, dwarf shrub heaths and moorland, scrub, deciduous and evergreen woodland and upland and lowland bogs. These maps can be used to plan, manage or monitor agriculture, ecology, conservation, forestry, environmental assessment, water supplies, urban spread, transport, telecommunications, recreation and mineral extraction.
The Northern Ireland data is currently available from Environment Download only but will be available in Environment Roam once we have created backdrop mapping and search infrastructure for Northern Ireland.
For details about Environment Digimap and how you can subscribe please see this earlier blog post:
Environment Digimap Launched: Free till July 2014

EDINA has added two new datasets to Geology Digimap ahead of the planned release date because of their usefulness when researching floods.
The new datasets have been provided by the British Geological Survey along with several other major products. The Geological Indicators of Flooding and Permeability Indices have been made available from the Geology Download facility early due to the recent flooding events across the UK.
These datasets along with LandCover data from Environment Digimap and digital terrain models, such as OS Terrain 50, from Digimap Ordnance Survey Collection, are all important pieces of information when researching flood risk, causes and potential methods of mitigating against them.
More information about these datasets can be found in the Geology Digimap help pages:
In addition to the two datasets already mentioned there are more new BGS products on the way. You can already download the Superficial Deposits Depth Model and we have the Soil Parent Material data coming soon.
Finally we hope to be integrating the most detailed geological mapping data at 1:10,000 and 1:25,000 scales to both Geology Roam and Geology Download.
If you require any assistance with these datasets or combining them with existing data from Digimap then please let us know:
//EDINA has updated the most detailed maps in Geology Digimap to the latest version from the British Geological Survey (BGS). The 1:50,000 scale maps and data in Geology Roam and Geology Download are now the DiGMapGB-50 Version 7 data from the BGS.
The main differences between this data and the previous versions is that there is an extra tile of data in Wales, EW150 Dinas Mawddwy, and that the linear features are now contained in a single shapefile rather than being in several separate layers. The 7 different linear feature layers; Alteration, Fault, Fold Axis, Fossil Horizon, Landform, Mineral Vein, and Rock are now all combined in a single Linear layer.
The following tiles have all undergone major changes:
For more details about the 1:50,000 and other DiGMapGB datasets you can download the Information Notes directly from the BGS: DiGMapGB Information Notes

EDINA and Jisc are pleased to announce the launch of a new Digimap Collection, Environment Digimap.
This new collection offers land cover map data from the Centre for Ecology & Hydrology (CEH). Environment Digimap is a subscription service; however, it will be available free of charge until 31 July 2014. After this period a subscription fee will apply per institution.
Environment Digimap offers two facilities: mapping through Environment Roam, and the ability to download data through Environment Download. The data available, CEH’s Land Cover Map products, provide a snapshot of land cover for each of the years 1990, 2000 and 2007. There are raster datasets available at 25m and 1km resolutions for each year and a vector version of the 2000 dataset. The data are in a range of formats depending on the year. More details are available in the Environment Digimap Help Pages: CEH Products Available
To use this service for free your institution needs to subscribe, this is free till the end of the 2013 – 14 academic year and can be arranged via the Jisc Collections website:
Jisc Collections: Environment Digimap
If your institution doesn’t subscribe the Environment Digimap button on the home page will be grey. Contact your Digimap site rep and they will be able to help arrange your institutions subscription: List of Digimap Site Reps

//We have updated three of the mapping datasets in Digimap Roam, so you can now view mapping published as recently as June 2013.
The products updated are:
These midscale maps are also available in a backdrop colour scheme which can be accessed by using the Basemaps tab at the top right of the map. The faded colours allow your annotations to show more strongly:
The updated datasets are also available from Digimap’s Data Download service (except MasterMap which will follow in the next few months), a page in Digimap Help details the all the OS products available and their currency in Roam and Data Download:
If you have any questions about the new data or any other issues relating to Digimap then please let us know:
//EDINA has launched a new version of Geology Download to replace the existing one and the Lexicon Download. The updated interface can be found in the Download area of the Geology section of Digimap.
The new interface looks very similar to the Data Download service in the Ordnance Survey Collection and so benefits from all the enhanced functionality and ease of use brought about when that interface was developed:
New Geology Download has all the datasets that the old interface provided, with the addition of the Lexicon of Named Rock Units and the Boreholes Index shapefile. We also hope to add some extra datasets in the coming weeks from the British Geological Survey (BGS) OpenGeoscience data holdings.
Both the old Geology Download and the Lexicon Download will be withdrawn on the 31st of August. If you support the use of Geology Digimap please update any support materials or practical exercises you may have created for the old interface.
You can find a “how to” guide for the updated interface here:
Please let us know if you have any questions or concerns about the new interface or withdrawal of the old ones:
