![]() Now, Sagiv Shifman, Jonathan Flint, and colleagues have provided a powerful new tool for genetic studies with the development in mice of the most detailed genetic map available for any species but humans. Because the mouse is a widely used model for genetic research, such capabilities would be invaluable. But these maps have lacked the resolution that investigators need to be able to do things like line them up against physical maps-the string of As, Gs, Cs, and Ts that gene sequencing supplies-to identify the precise location of genes, or explore the nuances of genetic recombination. We hope you have found some of these functions new and useful.Genetic maps of the mouse genome-which identify the relative locations of specific stretches of DNA based on the likelihood of their being separated when chromosomes exchange parts during meiosis-work well for broadly defining where various points lie along a mouse’s chromosomes. Go to the Zoom and pan viewer to try this.This is useful for showing the map you have been looking at in its real-world location, so you can compare it with other georeferenced layers. The Explore Georeferenced Maps viewer will then open, showing the georeferenced layer the map is from, centred on the place you have clicked on. Select View georeferenced location to click on the map and view its location in the Explore Georeferenced Maps viewer.This is useful for showing the outlines of the map in their real-world location, allowing you to also view other maps covering the same place, or adjacent maps. The Find by Place viewer will then open, showing the location of the map, with its outlines/extents highlighted along with maps from the same series. Select Show map location if you want to see the location of this map in the Find by Place viewer.If you copy this longer URL, it will link to the specific part of the map - useful for sharing this specific part of the map with others. This includes zoom=, lat= and lon= parameters (highlighted in pink below in the address bar) which relate to the original image and pixel dimensions. A suffix will be added to the standard URL. To save or send a link to a more specific part of the map, zoom and pan to the area you are interested in, then select the Link to this view tab (circled in red below). view/ ) presents the initial view of the whole map on the screen. Link to a specific part of the map, in the Zoom and pan viewerīy default, the standard URL for each map (ie. Many thanks for reading this far! Once we got going, we actually found we had a few more than ten things:ġ1. Go to the Explore Georeferenced Maps viewer to try this. ![]() This rotates the map in all of our viewers, in Map Finder, Explore Georeferenced Maps, the Records viewer or the Boundaries viewer, as well as the Zoom and pan viewer. You can also filter the date range and scales of the returned maps. Click on the map image thumbnails to view the maps. The maps covering the marker location appear in the Results on the right. Just Move the marker to your place of interest. This is the quickest way to find everything that we have online covering a particular place. Find all the maps of a place with the Map Finder - with Marker search Our Recent Additions page provides details of our latest updates. Less than half of these maps are georeferenced, especially pre-Ordnance Survey maps. ![]() This is around 15% of our collection the aim is to make over 30% available online by 2025. The geographic focus is on Scotland, but there is good coverage of Ordnance Survey maps of England and Wales too, and of scattered places beyond the United Kingdom. We now have just over 230,000 maps online (July 2020).
