Maps were drawn up showing the location and extent of each property and plot of land to be valued. The maps used were Ordnance Survey sheets at various scales, to which the district valuation officer added, normally in red ink, the hereditament numbers – one number for each property or parcel of land (numbers valued with another just appeared under the main hereditament number. The most frequently used scale was 1:2500 (about 25 inches to the mile), with smaller or larger scales being used for areas of low population or towns or cities. The maps for Badsey, Aldington, Wickhamford and Blackminster are all 1:2500 and based on the Ordnance Survey maps, c1900-1904. The extent of each hereditament was shown by a colour-wash along the boundaries, often in pink or green. The boundary of the ITP (income tax parish) was marked in yellow. Two sets of maps were created: working plans (used by the valuer in the field during the actual survey) and record sheet plans (intended to be a permanent reference tool and kept in the district valuation offices).
