If you wish to localise an LP made from the analysis of a text not in (e)LALME, you can use the setup below. This process is called 'fitting' (Benskin, M. (1991). Regionalism in late medieval manuscripts and texts: essays celebrating the publication of A linguistic atlas of late mediaeval English, Chapter The 'Fit'-Technique Explained, pp. 9-26. Cambridge: D.S. Brewer.)

In the first column, select one or more of the items for which you have spellings in the LP. On the second column, select those forms that are attested in the LP.
The map on the right is initially loaded with all the locations recorded in LALME. By clicking on the 'Fit forms on map' button, you will see the colour of map markers changing (they change gradually from dark red to whitish pink). The darker the marker, the more likely it is that the LP is a fit for that particular location.
If you click on the markers, you will see a link to the LP's at that location, but also which of the forms you are trying to fit is also attested there (if any). White markers signify locations where no forms are attested at all for any of the selected items.

Likelihood of a fit: the darker the marker remains, the closer the new LP (or the set of features being examined) is to the data attested at that location (marker); the paler it gets, the less likely it becomes for the new LP to belong linguistically to the same area.

If you want to restart a search, click on the 'Reset locations' button at the bottom right corner. This resetting is also done automatically every time you click on 'Fit forms on map'. In other words, every fit starts from the same map state (all dark red). Note that you can still build up an incremental picture as you would using the printed LALME with pencil and tracing paper. Choose one item and (a set of) form(s) and click "Fit forms on map". This will show the first stage of possible fit. The dots for the locations lacking the selected forms will either become one stage lighter - indicating presence of one or more forms for that item different from those selected - or become white - showing that the item is not attested in any form at that location.
If you repeat this process one item and (set of) form(s) at a time, the picture will gradually build up just as with the pencil and paper method. Less likely areas of localisation will be 'shaded' lighter and more likely areas darker. Remember also that if any dot becomes and remains white, this indicates that there is no information for any of your selected items. That place/region should not therefore be eliminated as a possible localisation, unless it is isolated in an area positively excluded by the presence of pale(d) dots. Remember also that a dot will remain dark, even if it has only a single positive match provided it has no information for any of the other selected items.
