The data are then stored with the project details in some type of file. ...
Flying High
The technology to collect LiDAR data from aircraft has been commercially available since the mid-1990s. As this technology has become more widespread and more familiar, it has been increasingly used to measure topography and create digital elevation models.
Connecting the Dots
Creating a compelling case for investing in new technology can feel much like a game of dot-to-dot. The crusader starts at point one--the demystifying dot--and slowly moves from one dot of persuasion to the next, waiting for each stakeholder to experience his or her “aha” moment ...

An Eagle Eye
In 2005, I performed an ALTA/ACSM Land Title Survey of a very large tract of property along Lake Erie in southeast Michigan. Sounds straightforward, but there was a challenge that lay before me: The lakefront property contained an active bald eagle nest.

Hacia La Excelencia: Toward Excellence
While many lament that new surveyors are entering the profession with insufficient mathematical skills or drive, this is not true of the surveying graduates at the University of Puerto Rico (UPR). Surveying students at UPR are very comfortable with trigonometry and easily handle the calculus and matrix algebra necessary for least squares adjustments, map projections and physical geodesy courses. In fact, UPR students not only demonstrate a passion for their studies, they have a passion for surveying in general.
The Speed of Integration
When the CH2M HILL survey crew set out to bid on a project to map 1,500 sewer manholes for Oregon’s City of Woodburn, the challenge was to gather and organize a diverse group of data with a limited budget.
