WhiteStarLine Posted 20 August , 2014 Share Posted 20 August , 2014 Please carefully read the McMaster University user agreement before attempting any of these processes. With the intent of completely complying with the agreement, I have recently downloaded over 560 British Trench Maps from the McMaster University web site. These are very high resolution scans, occupying a total of 13.8 GB disk space. The size of each map differs, but for example the 1:10,000 maps produce a JPEG file of around 28 MB each. My intended purpose is to assist me with studying Australian forces on the Western Front and to assist others looking for a location or reconciling a WW1 position with a contemporary Google or Bing map, given a little geospatial knowledge. Please read the license agreement. When you have done this, then this article will show you how to download one or more maps, then convert the supplied JP2 file into a JPEG. There a several pitfalls that I learned by trial and error, so I will share these. McMaster University's Digital Archive of World War 1 trench maps and aerial photographs is hosted at http://digitalarchive.mcmaster.ca/islandora/object/macrepo:34. The instructions apply to any map in any order, but let us assume you want to download several and run a batch conversion to convert them to JPEG in one go. For the sake of a tutorial approach, click on Trench maps and you will see a page with a preview of around 12 maps. 1 Click on the first map. 2 Your browser should be displaying a map with the title Trench map, World War, 1914-1918; , France. October, 1918 - 1:20,000. You can do lots of things on this page, but we only want to save it. 3 Click on "Download medium resolution (jp2)" or better still, right-click and select 'Save As'. Give the file a name that will be meaningful if you subsequently download a few of these. This one you might call Sheet 57A Le Nouvion October 1918 20,000. 4 The collection often has the same region at different dates or map scales. Download any others of interest. You now have a collection in a file format that a standard build Windows PC cannot open. Even worse, the JP2 file format boasts two standards and a number of the popular image processing applications such as GIMP, that claim to handle JP2 will not open any of these files. Neither will some of the free image conversion programs, such as XnView. However, the highly-regarded IrfanView not only lets you view JP2 files and save them to JPEG, but ships with a batch converter that works flawlessly. It even lets you bulk rename files. And did I mention that it is free? 1 Vist http://www.irfanview.com/ and download and install from the Downloads page. 2 Now, from the same web site, download and install the JP2 plugin from the Plugins Downloads page. 3 Run IrfanView. 4 Click 'File', then 'Batch Conversion/Rename' for a group of maps, or just Save for a single map. 5 For batch conversions, select the directory where you downloaded the JP2 files to and click Add. Select the directory you want to store the JPEGs in. All the other defaults should suffice (JPG conversion as the output). 6 Click 'Start Batch'. Your screen should look like this: Now wait! You are dealing with some large files and depending on your hardware, all operations take time. I used an older laptop and viewing a JP2 in IrfanView took 40 seconds to load and almost 10 minutes to convert to JPG. Opening and later closing the JPG in Windows File Viewer took 15 seconds but the resolution of the maps is very high. This is a one-off operation and you will need patience. The power management on my laptop would stop the conversion and it took 3 solid days to complete a third. I swapped to another laptop with more memory which converted maps in around 4 minutes each and finished the job in a day. Overall, I spent a week downloading, a weekend converting and as I use cloud storage, 3 days uploading. However, I am well pleased with the final result as the JPEG files load quite quickly and the detail is great. My thanks to McMaster for making this collection available and to Irfan Skiljan for his flawless conversion utility. I chose not to download maps from Gallipoli or other theatres. My results were: Peter Chasseaud Collection: * 188 maps of 1:10k scale; 5.0 GB Trench maps; 8.85 GB * 1:5,000; 3 maps * 1:10,000; 64 * 1:20,000; 146 * 1:40,000; 76 * 1:100,000; 75 * 1:250,000; 8 * Misc 6 I am happy to help anyone with questions.

kevmc Posted 20 August , 2014 Share Posted 20 August , 2014 A very comprehensive explanation. The subject concerning file types and McMaster has been covered on a number of occasions. For an example see here: http://1914-1918.invisionzone.com/forums/index.php?showtopic=209681&hl= That thread also makes reference to earlier threads covering this.

kevmc Posted 20 August , 2014 Share Posted 20 August , 2014 No doubt you will take some time to look at each map in detail. A massive undertaking to download all those maps. Be aware that some may not be what you expect. One of the Albert maps is actually a French map of 1914 showing coverage of the northern part of the Western Front up to the coast.

EDWARD1 Posted 20 August , 2014 Share Posted 20 August , 2014 They are free to access and are already overlaid on modern maps. You can view various dates of the same trench map keeping the same modern map and there is no need to download 13.8 GB and then overlay every map for each year. Click a mouse and your there.

WhiteStarLine Posted 20 August , 2014 Author Share Posted 20 August , 2014 Eddie, appreciate your posts on this. However, my instructions are for those who may not have a fast internet connection always at their hand or who prefer to open and navigate a local image. I also use NLS and it is a most useful resource. I am not advocating a single approach, just issuing instructions for those who want a local, always available trench map.

dobbin Posted 11 February , 2015 Share Posted 11 February , 2015 Bill thank you I thought I had lost it I will have some exiting moments going through it. I am preparing a web site for a dear lady in her 90s who is wanting to preserve the fascinating story of her father and his war service and survival. The first injury occurred near Ypres I was trying to find a more appropriate map to highlight the location. I have read the rules about copying and using maps rest assured I will do only as permitted. Many thanks I am always pleased to help in return. Best wishes Colin.

Guest Posted 17 December , 2016 Share Posted 17 December , 2016 Thank you for passing on your knowledge on map conversions very much appreciated.

MrEd Posted 14 November , 2018 Share Posted 14 November , 2018 sorry to ressurect an old thread, but what types of map would be best to view to to see where a siege battery was? trench maps or something else? Link to comment Share on other sites More sharing options...
WhiteStarLine Posted 16 November , 2018 Author Share Posted 16 November , 2018 MrEd, always good to see a member use an existing thread! Nothing beats using a trench map to find out exactly where they where and then display the location on a modern map. The National Library of Scotland is probably your best way of putting in a location and seeing on a Google Earth style display. For a single location, this is all you need. For multiple locations, tmapper.com converts them all and displays them on Google Earth. Each location has a clickable link to National Library of Scotland so you can overlay the trench map.

MrEd Posted 16 November , 2018 Share Posted 16 November , 2018 ahh brilliant thanks, the war diary fro my grandfathers unit has some really specific locations in it and details of places like 'black watch corner' polygon wood'etc. I would like to do a timeline of where they were and what they were doing and go visit them in order Link to comment Share on other sites More sharing options...
WhiteStarLine Posted 16 November , 2018 Author Share Posted 16 November , 2018 MrEd, once you have the latitude and longitude you can do this in Google Earth and by putting in the date for each location, have Google show a slider so that you can follow a unit in chronological order. Sing out for any help. Master this in a few hours and you can visit the Western Front. Do a bulk conversion in tmapper. Load pins into Google Maps, right click and select 'Directions to here'. Multi-country data SIMS are now cheap and prolific (ours was from Three and covered Belgium, France, Ireland and UK). Nothing beats mapping a bunker, having Google's voice on a tablet saying 'you have arrived at your destination' and spotting it. In 2016 and 2018 we followed trench map locations from the 11th AIF Brigade unit war diary and navigated to bunkers they used, a filled in Brigade HQ on the Somme and in obscure locations, undamaged trench segments, with the trench line full of new growth and an intersecting communication trench. Still waist-deep after being abandoned in September 1918 and surrounded by shell craters. Link to comment Share on other sites More sharing options...
