14. Inventory Survey Procedure Data collection considerations Significant variations in road and feature layout can occur when recording inventory The selected method must ensure the collection of data is consistent for all survey types It is important that inventory and other survey data are collected to complement rather than conflict with each other Alignment of inventory and condition data can have implications for data processing especially in connection with DVI data so the sections below explain steps which can be taken to minimise data conflicts Start and end location of section Inventory data can be collected in either the forward or reverse direction of the section further information on survey direction is given in Section 7 3 Survey Direction of Chapter 1 Overview of Visual Data Collection of Volume 2 of this UKPMS User Guide When collecting data in the reverse direction cross sectional positions should be recorded as they are observed recording the direction of the survey as reversed means that UKPMS will reverse the data and XSP codes automatically Definition of the start and end point of sections needs to be defined by the network model Section 7 3 Survey Direction of Chapter 1 All data collection must be undertaken consistently to the network model or data conflicts between different sutveys will be likely leading to survey data either not being accepted into the database or being lost during UKPMS processing Nominat
