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:

We are getting a few reports from users experiencing issues when printing PDF maps using Chrome web browser. Unfortunately, the map watermark and any semi-transparent annotations are being printed as solid filled features. We have discovered that this occurs when the PDF is viewed and printed from within the Chrome browser, using Chrome’s in built PDF plugin.

We have investigated this problem and discovered that the bug is with Chrome and occurs with all PDFs with semi-tranparent layers not just those created by Digimap. The problem only happens on Windows computers with versions of Chrome released since the end of April (Chrome 34.0.1847 onwards).

Digimap users with Chrome should see a warning when they open the Print… window, informing them about the problem.

Print interface showing chrome alert

As the alert message suggests you can disable the plug-in to prevent it from opening PDFs or you can use the following workaround.
Printing from Chrome alternative method

  • Create your printable map as normal it will appear at the bottom of your web browser.
  • Don’t click the file name to open the PDF, click the little arrow and choose ‘Open with system viewer’.
  • Providing it is installed on your machine, the map will open in Adobe Reader which will print the semi transparent layers correctly.

We hope that the issue is resolved by Google who develop the Chrome browser, it has been reported to them. Should you wish to disable the plug-in entirely then you can follow the instructions with the image below. You can also download the map as a file to your computer, and then open it directly with Adobe Reader, this is usually the best option anyway as it allows you to print the PDF multiple times or store it if you don’t want to print it just yet.

Disabling Chrome PDF plugin

  • Type Chrome://plugins into the web address bar in chrome, this opens a list of all the plug-ins you have installed for Chrome.
  • Scroll down to the Chrome PDF Viewer on the Plug-ins page and click on the blue “Disable” link.
  • You will no longer have the option to view PDFs in the web browser.
  • Use this page to reactivate the plug-in if you want to reverse the change in the future.

 

If you need any assistance with opening your PDF map, please contact the EDINA helpdesk:

Ancient Roam in Historic Digimap has had its print options updated so it now has the same set of options as the other Roam facilities. The two big changes to note are that you can now print up to A0 and that you can print a single county in areas where several overlap.

Until this change was made it was impossible to print an area with overlapping maps without printing all the counties available rather than just the one(s) you were viewing on the screen. Any print files now generated in areas with overlapping counties will only show those which are displayed on screen.  This allows you to have the control over how much information is on your map and to make the decision to show more or less information.

Overlapping Counties Print from Amcient RoamSingle County Print from Ancient Roam

Sometimes it can be an advantage to show multiple counties as even though the sheets overlap the actual map information doesn’t. However in the example above you can see how the counties overwrite each other in the map on the left and so produce a very confusing and fairly useless result; by switching one county off you can produce a much clearer print map such as the one on the right. [Click on the images above to view larger versions of the maps.]

The ability to print maps up to A0 brings Ancient Roam into line with the other Roam facilities so you can now print at this very large size in any Digimap collection.

You can now download high quality PDF maps from Ancient Roam for printing.  This element of the service has been quite tricky to implement, so until now we have only had the save image button  to get a PNG image of the map you are viewing.

Now you can use the print button  to access a similar interface to the ones found in all the other Roam services.  You can see a sample PDF by clicking on the thumbnail below:

There are still a couple of options to add into Ancient Roam print maps; we need to add the ability to print 2up maps and the ability to switch off counties in areas where there are overlapping maps. Look out for these arriving in the near future.

Information about how to use all the features of Ancient Roam can be found on the following help page:

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.

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.

On Tuesday 1st March, EDINA will be updating the metadata for the historical maps in Historic Digimap. The metadata changes will affect only the Scottish County Series maps and will mean that some maps will appear to “move decade”. More details of the implications of these changes are given below.

Accuracy of publication dates

When the maps were originally scanned, the detailed marginalia on the original paper map sheets was not captured at the same time. The marginalia contained information such as the survey year, publication year, re-publication year (if applicable) and surveyor name. During the digitisation process only one year from the marginalia was recorded; it is assumed this was the publication year but there was always some uncertainty around this.

A joint project between EDINA and the National Library of Scotland (NLS) was undertaken to digitise the marginalia of the original paper copies of the historical maps held by NLS. The metadata captured included the Survey Year and Publication Year. Until now, the survey year of all maps in Historic Digimap was unknown. We now have the survey year for a significant number (but not all) of the County Series maps for Scotland at both 1:2500 and 1:10 560 scales.

The significance of this project to Historic Digimap is that we can now use the more accurate and reliable publication dates for many of the County Series maps to improve the mapping and download facilities offered. In order to make use of the new NLS publication dates, these were matched with the original metadata using a series of rigorous database queries and manual processing.

How many maps have changed?

Consequently, around 35,000 County Series map tiles* (18%) now have survey years. Of these, around 28,000 tiles also have a more accurate publication date. In the majority of cases (over 70%) the publication date has only changed by a year or two. For nearly 2,000 tiles the change in publication date is more than 10 years, with the largest single change being 39 years. For those tiles which have not had updates to the survey year, the Landmark publication year used remains unchanged.

So what does this mean for Ancient Roam and Historic Download?

Nothing has changed in Historic Download in terms of how historical maps can be found and downloaded, but the updated publication dates will be reflected in dates provided on the order summary page in the downloader. These will be more accurate and reliable than previously.

For Ancient Roam, there are some more significant effects. The publication date is used to determine which maps are visible in each decade given in the timeline along the top of the map screen.

Many of the maps for which the publication date has changed by one or two years will remain within the same decade and therefore will not be affected. However, for some maps a change of a year or two in the publication date may be enough to shift the map from one decade to another. For example, a map previously thought to have been published in 1889 but now known to have been published in 1901, originally appeared in the 1890s decade but now appears in the 1900s decade.

Where there have been more significant changes in the publication date some have resulted in entirely new decades being available in the timeline for particular areas. For example, in Forfarshire there were two County Series editions in the 1890s. This was because maps originally published in the 1860s and 1870s were re-published in the 1890s. So where no maps appeared for Forfarshire in 1860/70s, they do now!

Other maps with significant publication date changes tend to be odd outlying tiles that for some reason had a significantly different date from neighbouring tiles. This means that some odd ‘holes’ have been filled.

How do I find out the map date source?

In addition to the new survey and publication data information, the Map Details information box will also be updated. A new icon has been added to the tool bar to access the map information and the information box styling has been updated in keeping with the other Digimap Roam clients. Three new attributes have been added to the Map Details information: Year Surveyed (where applicable), Sheet Title (where applicable) and Date Source. The Date Source information will tell you whether the publication year came from the original Landmark data or the NLS metadata.

While these changes to Scottish County Series maps means that the per decade classification is now different, the changes mean that the dates are now more accurate. Our thanks go to the National Library of Scotland for their hard work on this project.

The updates to Historic Digimap will take effect on the evening of 1 March 2011.

*Map tiles refers to the ‘cookie-cut’ National Grid versions of the maps, not the original County Sheets
