Abstract

This ontology marks up information about the British Trench Map Coordinate system used by Great Britain and its Dominions during the Great War. As part of the Muninn project, it was necessary to identify and translate the coordinate system to modern logitude and latitudes using a WGS84 datum.

This onlogy contains the different intances of all known map sheets used, the relationships that bind them and the underlying organisation of the coordinate system. It is currently used to drive coordinate translation applications and as a reference to the different battlefields of the conflict. Ontological structures are borrowed from the modern British Ordonance Ontologies1 as well as from other ontologies.

Outline

Introduction

With the invasion of Belgium by the Germans, the Belgian plates for their countries maps were made

Trench Maps Sheets

The actual projection of British Trench maps is the Belgian Bonne projection which was also used by the French for their military maps at this time. The Ellipsoid, or the specific size and shape of the planet, was the Delambre one from 1810. The origin at Brussels is a point of contention; different publications report different locations. Another reports the origin as being the old Brussels observatory which unfortunately moved several times. Both the positions recorded by Mugnier as 50°25'0.0006", 4°22'12.6978" and Winterbotham (see also Close:1919zr) as 51°10'06.895", 4°22'05.89" are both a few kilometers off. After a bit of help from the Nationaal Geografisch Instituut and the original triangulation of Belgium [#institut1867triangulation], the actual origin of the map as 50°24', 4°22'5.89", which give results that are reasonable.

Accuracy

A trench map is made from several different sources of mapping information: on site surveys, larger scale maps (1:100,000), fire direction maps and the original 1:40,000 belgium grid plates.

Every map at the 1:40,000 level has a short thumbnail on the margin of the sheet that explains the sources used to create the specific sheet. In the case of the image below, this specific map was created from the Belgian plates and the French plan directeur for artilery fire. (The Belgian 1:20,000 map is a magnification of the 1:40,000 map.)

According to Winterbotham, the accuracy you can expect of the map varies wildly depending on the source used to create it. While the reprojection of large scale maps (1:100,000) down to smaller (1:40,000) scale was performed often at the begining of the war, one could expect errors of about 200 yards. A survey units making maps from sightings or arial photographs would aim for an accuracy of about 20 yards.

The grid precision goes down to a box of 50x50 yards and with the help of a very good eye and a romer, a box of 5x5 yards. This would be assuming that the position would be properly fixed by a soldier in an environment that was not perticularly ideal. This also meant that positions were assumed to be "roughly there" and anything requiring good precision, such as tunneling and registering artillery fire, would require some specialist survey teams.

Trench Maps, 1:40,000 Series

The 1:40,000 maps were the basic map series from which operations where planned and situational awereness acheived. The basic Belgian grid is extended by adding alphabetic extensions to the basic grid for areas outside of Belgium. Be aware that not all grids are listed below and more exist for the 1:40,000 grid.

Overview map of all 1:40,000 British Trench Maps.

The 1:40,000 grids were subdivided into several 1:20,000 and 1:10,000 sheets.

Trench Maps, 1:10,000 Series

The 1:10,000 maps were the primary maps used by the front line officers and enlisted men by providing small scale views of the battlefields. Each 1:10,000 map was a quadran of a 1:40,000 map, named NW, SW, NE, or SE.

Ontology properties

The ontology provides the following properties:

While the properties are used by both sheets and references, their application are slightly different in both cases due to the hybrid nature of the metric / imperial system. The actual physical size of the represented terrain is encoded the same way for both sheets and references.

The size of maps and coordinate boxes are reported in Yards.

Trench Map Sheets

Sheets within the grid are organized so that each grid touches another exactly at its edges.

All grid squares are related to their adjoining squares.

Trench Map References

The properties for a grid reference.

Trench Map references where created as an imperial measurement grid over a metric projection. Be aware that the origins of an easting and northing are relative to an origin. Within the Belgian grid, the origin is at Brussels. In the Grid Reference, the origin is the South West corner of the square.

Geometries

The area covered by the grid reference is translated to a longitude and latitude with a WGS84 datum. Currently there are two ways to represent a polygon in linked open data: using the methods preferred by Linked Geo Data and as a collection of geo:Point nodes. A centroid is reported for both Map grid and Map reference for use in labeling on large scale maps.

Figure x represents the structure used by linked geo data for the representation of a polygon using a rdf mapping used by virtrdf:Geometry http://virtuoso.openlinksw.com and GeoSPARQL ogcsparqkhttp://www.opengis.net/rdf#. Both are an rdf serialization of the opengis standard which encapsulates the XML standards into litterals.

Figure - Linked list style geometry.

Figure y represents the structure using a series of geo:Points that are linked together using two properties that enforce the ordering of Points in the polygon. The intent of this representation is to make the longtiude and latitude accessible through a SPARQL or XPATH query without parsing while making the enforcement of point ordering OWL safe.

Figure - Linked Geo Data / GeoSPARQL geometry.

The use of within and contains properties relates the grid reference to its parent and child grid references as well as adjacent grid references.
