Main Roads WA Geodetic Control data, used to underpin engineering grade survey, mapping and laser scanning operations. Points contain MGA or Project Zone coordinate values, horizontal and vertical accuracy and methodology, with supporting Latitude and Longitude values in GDA94 or GDA2020 as appropriate.This data is used for road investigation, planning, design, construction and asset management. The geodetic control network underpins the relative accuracy of the survey data, and in conjunction with the project zones, provides surveyors with an important resource to ensure engineering survey standards are met and maintained.The data within this layer is continually maintained and edited on a daily basis.Data Dictionary: https://bit.ly/32uGPoF
