MARKING MAPS

5.1

Introduction
5.1.1 A variety of sources can be used to plot the distribution of land uses (se also Section 2.2):
a. Ordnance Survey maps at 1:25,000 and 1:50,000 scale;
b. A to Z Gazetteers;
c. Other Sources.
5.1.2 Ordnance Survey Maps
Ordnance Survey maps are a good starting point for assessing land uses.
5.1.3 Obtain colour copies of Ordnance survey 1:50,000 ‘Landranger’ and, preferably, 1:25,000 ‘Explorer’ maps of the district. These maps can be purchased through main booksellers, or similarly scaled maps can be obtained from the local authority’s mapping section, subject to the terms of the Ordnance Survey’s licence.
5.1.4 The Ordnance Survey maps show ‘A’ and ‘B’ roads and other adopted roads, together with the location of many ‘Other Highways’ (Bridleways, BOATS (Byways Open To All Traffic) and RUPPs (Roads Used As Public Paths), and Restricted Byways), as well as indicating the distinctive development patterns of terraced housing, industrial areas, etc.
5.1.5 A to Z Gazetteers
A to Z Gazetteers have been published that cover large areas of England – including Collins, Phillips, Ordnance Survey and other, sometimes local, publications. They may help to identify Commercial, Housing, Industrial and Recreation areas, as well as Main Roads and Rural Roads.
5.1.6 Other Sources
The Code of Practice on Litter and Refuse (COPL&R), updated in November 2006, requires all Principal Litter Authorities to prepare a map of its district identifying areas of high, medium and low intensity of activity, and areas with special circumstances. COPL&R (p20ff) links these zones to the standard Land Uses used by the previous Cleanliness Performance Indicator BVPI 199.
5.1.7 Where authorities have prepared this zoning map, for which COPL&R sets a target date of 1st April 2008, this should provide a source for the mapping required for NI 195.
5.1.8 The Highways Department should be able to assist in identifying some types of Other Highway – bridleways etc. from the Definitive Rights of Way map, and possibly a schedule of laybys.
5.1.9 Local knowledge and site inspections may be also used to supplement map-based information (see Section 5.2 – ‘Scouting the Target Wards’).
5.1.10 Using a combination of the information sources listed in Section 5.1, mark the general location of land -uses (including proposed developments) on the ward boundary map using coloured felt pens.
5.1.11 Where authorities have access to computerised Geographic Information System (GIS) facilities, this may be done using their computer system. This could give authorities the potential to map information collected during their NI 195 surveys, and to link it to other sets of information.
5.1.12 Figure 5.1 details a representation of the Ladywell Ward land-use categories provided by the London Borough of Lewisham as an example of identifying land-use classes within a ward.

Scouting the Target Wards
5.2.1 Local authorities are recommended to ’scout’ each of the target wards before surveying. ‘Scouting’ should be done just prior to starting a survey in a target ward.
5.2.2 The data gathered through scouting will improve the accuracy of the survey mapping.
5.2.3 In particular, the scouting process will be helpful in identifying areas of High, Medium and Low Obstruction Housing, and any informal lay-bys, back lanes and alleys etc. which form part of the ‘Other Highways’ category.
5.2.4 It will also help to ensure that a sample is obtained that is ‘representative’ of the range of land-uses that are present and the types of development that exist.
