Route Analysis

Ogilby's Hampshire 1675


index map


introduction John Ogilby's innovative project published in 1675 made maps of roads at 1 inch to 1 mile. It includes several roads passing through Hampshire. The strip maps include features on the roads and nearby.

These maps were the source for many imitations. They were used by later map makers, who included all or most of Ogilby's set of routes in strip maps and on county maps of Hampshire for the next hundred years. The routes are important in their own right and as a 17th century map of parts of Hampshire.

sources The detailed scroll by scroll comparison of Ogilby's with modern maps is an interpretation; an opinion based mainly on the study of Ogilby's maps compared with the OS 1:25000 sheets, 1965-1992, and information from the OS Street Atlases:-

methods
and
conventions
Ogilby's scrolls have been cut up, with transcriptions of the contemporary pages of descriptive text that accompanied the plates given below each section. Ogilby's words are in italic. Our commentary is given alongside.

'Left' and 'right' in our notes assume the traveller is going up the page, the mile numbers increasing. The start of a road on a sheet is the bottom of the leftmost scroll.

The distances given are based on the position of the maps' mile numbers, even when they do not match the double spots which are intended to mark the miles. This makes it easier to match features at a glance; the figures usually agree with the descriptive text. The nearest furlong below is specified as a guide and ordering device; the furlong cannot be precise where the miles are inaccurately placed and where spots are missing from the strip map. Whatever system is used there will be some inconsistencies, including some miles which are too long. At scroll ends there may be problems with legibility, sometimes a small overlap or gap between scrolls and a few distances copied innaccurately between routes.

Compass bearings are given only to false point accuracy. John Ogilby's preface shows that he was aware of magnetic deviation, which was about 3 degrees west in 1675.

Modern road names and numbers are given approximately every mile, unless they change more frequently. Brackets around a road number implies that it was formerly used; in many instances main roads have been diverted as recently as the last few decades of the 20th century. It is worth saying that Ministry of Transport road numbers are not stable in the long term and should not be used by researchers as 'fixed' or 'safe' references to routes.

NGR
precision
National grid coordinates for turnings, places and other features on and beside the roads are given where possible in order to aid identification. The NGR reference system is stable in the long term, enabling the future reader to match places, and allow informed criticism.

Various degrees of accuracy are used: for example, a village off the road marked on Ogilby's map by its church will be assigned the 8 figure ngr of the church if it can be identified; on the other hand an area of heath may cover several 4 figure ngr squares.

8 figure grid references for features on the road itself are shown in bold type, and these can be used to help plot Ogilby's route on a modern map of Hampshire, but it must be understood that they are a guide only, and that the degree of precision implied is false. For a settlement or a mile number the ngr given is a best guess. The coordinates given for a cross roads mark where the turnings now meet the present road. Except where buildings lined the route, it is important to realise that roads were less well defined in the 17th century when less land was enclosed, and before the introduction of all weather road surfaces. John Ogilby on horseback may have recorded the exact path he took within those roads; the lines he draws look surprisingly uniform in comparison with the wandering roads of variable width that appear on Taylor 1759.


how good
a match?
The analysis presented here started as a rough guide to John Ogilby's routes in Hampshire. It demonstrated that the surveying was good enough overall to allow the strip maps to be cut and pasted into a combined map which fits well to a map of Hampshire. The analysis has grown into this much larger project because it is possible to do more. John Ogilby's accuracy of surveying and mapping, in particular his measuring of distances, and the inclusion of bends and turnings, has allowed accurate and detailed identification of substantial parts of his routes. These strip maps provide more than just a diagramatic representation of the roads and the bends are significant, though the bearings appear less accurate when the maps are looked at closely. A possible reason is the constraint of the width of each scroll. And there are some sections of road drawn as a straight line where the actual route is almost certainly not straight, such as the road parallel to the Itchen south of High Bridge, on plate 51.

The introduction of turnpikes does not seem to have had a great effect on Ogilby's routes in Hampshire. Road realignment and major road building during the 20th century has had an impact, though signs of previous routes are often still visible, sometimes appearing more clearly on the OS 1:25000 map than on the ground. The most difficult parts of roads to trace are where there are now suburbs, or where routes went across unenclosed downland and heath.

There are sometimes inconsistencies in numbering between a scroll and the accompanying text, not match. This is particularly noticeable in Basingstoke, plates 25, 53 and 81, and Petersfield, plates 30, 39 and 81.

Raw data for plotting can be downloaded for each plate.

Our interpretation of Ogilby's route on a coloured relief background is included in the topic on road books.
