Abstract

Raw TM data of a single scene of southern England without PCD or MSCD have been transformed to British National Grid coordinates using 101 GCPs. For a whole scene in one transformation, third order is the minimum acceptable for raw data of this state. The standard deviation of the residuals was reduced to sub-pixel level using third or fourth order polynomial transformations, but the 90% level is about 40 metres or 1.3 pixels, allowing accurate planimetric mapping to scales of 1/100 000 and smaller. System corrected data have been shown to be marginally better, and under the most favourable conditions both raw and corrected data may be marginally suitable for mapping at 1/50 000.
