Insurance Plan of London Western District Vol. A: Key Plan
1 : 21120 This "key plan" indicates coverage of the Goad 1901 series of fire insurance maps of London that were originally produced to aid insurance companies in assessing fire risks. The building footprints, their use (commercial, residential, educational, etc.), the number of floors and the height of the building, as well as construction materials (and thus risk of burning) and special fire hazards (chemicals, kilns, ovens) were documented in order to estimate premiums. Names of individual businesses, property lines, and addresses were also often recorded. Together these maps provide a rich historical shapshot of the commercial activity and urban landscape of towns and cities at the time.
The British Library holds a comprehensive collection of fire insurance plans produced by the London-based firm Charles E. Goad Ltd. dating back to 1885. These plans were made for most important towns and cities of the British Isles at the scales of 1:480 (1 inch to 40 feet), as well as many foreign towns at 1:600 (1 inch to 50 feet).

In the second half of the18th century, the introduction of turnpike roads and the increased coach-traffic in and out of London contributed to the popularity of the maps of the countryside around the capital. This map of the area ten miles round the City of London was published in Amsterdam by Isaak Tirion. Based on John Rocque's survey of 1744, the map’s title, imprint and key appears in a table at top left. The scale bars are in a panel below the plan. Built-up areas are stippled in the City and hatched elsewhere. Tirion, Isaak
LONDON AND ITS ENVIRONS LEVELS TAKEN BY ORDER OF THE COMMISSIONERS OF SEWERS
The cholera outbreaks of the 1830s and 1840s forced the government to make drastic improvements to the methods of drainage and sewage disposal in London. A Metropolitan Commission of Sewers was charged with the central task of unifying the existing piecemeal drainage system and forming a plan for a completely new one. A new map showing the levels of the land to be drained was needed for this. In March 1848, officers of the Royal Engineers began to prepare stations for triangulation. Observation posts were set up on one of the towers of Westminster Abbey and over the cross of St Paul's. This map is the result of the survey, showing the relative altitude of the land, a necessary preamble to planning drainage systems, as sewage can only be washed away downhill. Wyld, James
JURISDICTION OF THE METROPOLITAN POLICE
This map illustrates plans for the reform of the jurisdiction of Metropolitan Police. Based on Dawson's map of 1832, the map’s title appear along the top, with compass star at top right, explanatory note at bottom left, and a scale bar at bottom right. District boundaries are highlighted in colour, with the old limits of London, Westminster and Southwark shaded. Formed in 1829, the Metropolitan Police had its jurisdiction extended in 1839to Greater London - an area taken to mean all parishes partly within twelve miles of Charing Cross or wholly within fifteen miles of Charing Cross. In the same year, the City of London formed its own police force. Dawson, Lieut. Robert K.
