Synopsis of Topic
A hybrid survey is simply a term we use for surveys and DEMs that are derived from topographic surveys that involved the use of multiple survey methods (e.g. total station, ariborne LiDaR and multi-beam SONAR). One of the problems with hybrid surveys is that modeling elevation uncertainty might require a different approach for each survey method. How do we mix and match different methods, yet keep all the analysis together in one clean package? The GCD software now supports this increasingly common dilema. In this segment we will cover how to do this.
Why we're Covering it
As spatial extent of surveys expands and the number of topographic methods explodes, it is increasingly common to need multiple survey methods to build a complete topographic picture of an area. This session focuses on workflows to accommodate this new reality.
Learning Outcomes Supported
