Historical Mapping

1. Historical Mapping We can look at a collection of Ordnance Survey historical maps, and download these for use in research projects. The coverage starts with the County Series maps of the mid nineteenth century and extends up to the time modern digital data was used by O.S. (1990’s) You can examine a single map in a variety of scales and dates, or compare 2 or 4 maps of various dates on the same screen. This enables you to compare changes over a period of time. The first step is to go back to the Digimap home page . 1.Then click on the “ Historic Digimap ” icon. 2.Select your Map Series and Edition and locate the area by using a place name postcode etc. 3.Choose the precise location if options are offered and use the Goto button. 4.Select the area you wish to examine by using the map tools,( View Historic Map) and clicking on the map square required.

3. 4. Select the area you wish to examine by using the map tools,( View Historic Map) and clicking on the map square required. 5. An enlarged section of map will be shown, you can navigate across the map by using the buttons along the sides or by clicking on the map to re-centre it. 6. Shows the option to view two maps at once, the second one can be changed to view any of the available options. 7. This time up to four maps can be viewed together, each one could be a different date (if four options are available). You can print out a copy of the map from the screen at this stage but the quality would be poor. It is much better to save a copy as a tif file and download it to your computer, where you can put it into various software packages and print it out.

5. Follow the on screen steps to download the historical map tif file. Place the tif into a suitable programme and either edit further or print out as required.

6. There is another historical mapping data set available, this one is based upon the 1931 – 1935 land use survey carried out by Douglas Stamp. Again you can navigate across the country ( England & Wales only this time ) and print out a colour copy from the screen. The first step is to return to the home page and click on the “Historic Digimap” button. Click on the “Land Use Map Viewer” button under “Other historical resources” and a map appears, on the left is a current map and on the right the land use one. You locate your area of interest by using the “Search for Place” box or by inserting co-ordinates in the “Easting” and “Northing” boxes. You can also click on the re-centre mode box then click on the map and zoom in to locate your required mapping. The left hand pane will mirror the land use map but show an up to date typographical version. A “Land Use Types” key can be displayed by clicking on the “Key” button, this can be saved and downloaded for insertion on your mapping.
