Machine Survey Pre-processor software

This software is no longer supported or updated and does not process all parameters required for the current SCANNER Specifications.

This software is being made available for developers who wish to use the code as a starting point for developing their own processing software for current standards. If you are using this software for any purpose you do so at your own risk. Please see the software Terms and Conditions before downloading.

The Machine Survey Pre-processor (MSP) was a software application developed by the Highways Agency to pre-process machine survey data before loading into the Highways Agency’s Pavement Management System (HAPMS). From version 7.0, the functionality of the MSP was extended to include the pre-processing of SCANNER data collected on local roads. However, this MSP is no longer supported or updated and is not suitable for pre-processing SCANNER data generated over the past 2-3 years.

MSP software in general is aimed at carrying out the necessary pre-processing of raw SCANNER data (RCD) to produce the SCANNER HMDIF file required for loading into UKPMS. The MSP software is usually developed to:

• Read and validate the format and consistency of the SCANNER RCD;
• Validate the measured values;
• Carry out corrections to and/or analysis of the measured values;
• Calculate the parameters that are derived from the measured values (e.g. SMTD);
• Calculate the elapsed chainages of section start points for which the location has been provided in the route file as National Grid Co-ordinates;
• Enable the Survey Contractor to fit the survey to the route defined in the route file; and,
• Outputs the measured values, the parameters that are derived from the measured values (as appropriate), and the fitting information as a SCANNER HMDIF file.

Survey Contractors are permitted to use their own facilities to provide the same functionality as the MSP and therefore the decision has been taken, with the agreement of the Highways Agency, to make the MSP source code available to download, subject to certain legal terms and conditions.
