The SABRE Maps Sheetfinder is currently considered to be in an uncompleted state. Not all available maps can yet be accessed via the Sheetfinder. Work is continuing to add more over time. |
The SABRE Maps Sheetfinder is a sub-project of SABRE Maps, and is an alternative front-end showing overlays of all available maps on SABRE Maps at each scale.
It was borne from the realisation that with the sheer number of individual map sheets available on SABRE Maps, users were not able to find all available maps of their area of interest. This is rectified with the Sheetfinder, where a user can click on any location on a map of Great Britain and Ireland, and be presented with a list of all sheets of the selected scale available on SABRE Maps of that location.
Using the Sheetfinder
Upon opening the SABRE Maps Sheetfinder, users are greeted with an OpenStreetMap base map, centred on Great Britain and Ireland, with areas to the left and right.
Within the left hand area, controls are located to select a particular map scale that a user is interested in. These are grouped together in appropriate like-scaled sets, so for example, Quarter Inch and 1:250,000 maps are grouped together in a single section. As the user selects a different scale, different coloured overlays appear on the central map. Each coloured shape represents a single map sheet, so where map sheets have overlaps, they are shown correctly as being overlapping.
Also within the left hand area is a search box. Please note that this search is a worldwide one, and so care needs to be taken to select the correct location. Typing in a location, then selecting it will zoom the centred map into that location.
Central map area
The largest part of the Sheetfinder window is the central area containing the main map interface. This map can be moved, scrolled, and zoomed in and out in order to put any location at the centre of the map.
When the user wishes to view maps of a location available on SABRE Maps, they click on that location. If there is at least one map available of that location at the selected scale, it is displayed within the right hand results area.
Right results area
Once a user has clicked on a location, all maps available at that scale of that location are then displayed within the results area on the right hand side of the Sheetfinder window.
These results are sorted by series, sheet and then individual revision by age; with some information about each map and a small thumbnail. By clicking on either the thumbnail or the highlighted map name, a user is then taken to the centre of that map within SABRE Maps.
Clicking on a further location on the central map will update the results area to show that location.
