Aligning FDOT Practices with the New ASPRS Positional Accuracy Standards for Digital Geospatial Data

6/3/2019 - 3:00pm-3:50pm

The new ASPRS Positional Accuracy Standards for Digital Geospatial Data is the first mapping accuracy standard designed for today s digital geospatial data and sensors. Almost all existing technical mapping and surveying specifications, including the one used by state DOTs, were developed during periods preceding current mapping practices and the latest digital sensor technologies. In prior specifications, product accuracy was expressed in term of scale and contour intervals, as designed for paper maps. New accuracy measures are needed to represent current digital mapping processes. This presentation will highlight the benefits that new accuracy standards bring to any organization using or producing geospatial mapping products. It will also provide practical means for modifying existing specifications, including those used by FDOT, to make them more suitable for today's mapping and surveying practices. During this presentation, the audience will learn how to design project accuracy specifications that are aligned with the latest ASPRS accuracy standards and suitable for today's mapping practices and technologies.
