UAS and ALTA Surveys

Part 3 Precision, accuracy, and completeness are the end goals of UAS post processing, but how you get there to meet ALTA standards requires extra care. In Parts One and Two of this article in the September and October 2022 issues of xyHt we looked at the time/cost/precision proposition of using UAS for elements of...

UAS and ALTA Surveys – Part Two

Surveying firms that have been successful in incorporating UAS data in ALTA surveys adopt best practices to ensure precision standards are met. Plan, execute, and check. In Part One of this three-part series in the September xyHt issue, we looked at the time/cost/precision proposition of using UAS for elements of ALTA surveys. Firms interviewed agreed...

The GeoDude on Scanning Efficiency

A Snapshot from the GeoDude on Rich Data Here’s a comparison of today’s field and office efficiencies—for conventional surveying methods versus laser scanning—as applied to topographic and site surveys. Above: The firm that used scanning for this site survey noted that more than 60% of these types of projects entail scope creep; scanning typically avoids go-backs....
