Doyleâs first eight courses are offered as a series, though you can pick and choose. The first is an introductory stage-setting course on geodetic fundamentals for those who have been hesitant to delve into any geodesy-related topic. It is an excellent primer for a broad spectrum of geospatial professionals and technicians in fields such as land surveying, engineering and technical GIS applications. The rest of the series includes two on classical horizontal datums and contemporary horizontal datums and two on vertical datums. He includes an additional course on future datums and another on coordinate systems. â©
Doyleâs ninth course uncovers the âsecret sauceâ to understanding and using NGS data sheets. It helps novices and experienced alike to understand all the clues and guideposts embedded in such sheets. Doyle includes a discussion of how to understand the accuracy (horizontal and vertical) of various marks based on the metadata provided right in the data sheet. Also included is information on how to access photographs of the marks and how you can update the information using a simple program that you can download from the NGS website.â©
âIâve been addressing groups of surveyors and other professionals who use NGS data. In these courses, I take those decades of interaction and try to anticipate and address the most common problems theyâve encountered and most of the questions they would ask,â says Doyle.â©
