The Principles & Practice series is a focus on the fundamental principles of land surveying and how those principles impact land surveying practice. The case-in-chief for this edition is Southeastern Reprographic v. State Registration Board of Pennsylvania, Commonwealth Court of Pennsylvania, 2016. This case is about the definition of the “Practice of Land Surveying.” This is a fundamental practice issue, in that it separates the licensed and regulated practice of surveying from other, similar, activities. This case involves an unlicensed GIS company that conducted GPS field surveys to inventory the physical assets of an electric cooperative and complied the data into a GIS. The Pennsylvania Board consider this to be the practice of land surveying. As a result, the definition of the “Practice of Land Surveying” became the Ultimate Issue in the case. This is a 2-Page Letter covering one Court Opinion consisting of 14 pages. Altogether, this is a 16-Page document with a 10-Question examination based on the text of the newsletter and the case-in-chief.
