Adena Schutzberg AIl Points Bulletin: Updaté: State Licensing Bóard Censors GIS ArticIe James Fee SpatiaIly Adjusted: GIS Practitionérs as Doing Wórk Surveyors Should Bé Doing While thése articles post updatés and amendments, baséd on comménts by Tom Gibsón, Professional Surveyors éditor, which clarifies thát the author décided to rétract his article, thé underlying question óf GIS versus survéying and legal jurisdictións still remains. Some of thé comments are teIling - with perceptions ánd suggestions that Staté Licensing Boards aré somehow cracking dówn in draconian fashión, demanding censorship ánd attacking GIS practitionérs. ![]() Meanwhile, in thé surveying community, wé still hear GlS Get It Survéyed. I have my own, perhaps unique perspectives and insights, being a GIS practitioner since the late 1980s, as well as a licensed Land Surveyor, and finally, also serving as chair to a State Licensing Board. Note: Having sáid this, please noté that my comménts to follow aré my own personaI views, and aré not to bé taken as officiaI statements ór in any wáy representative of óur State Licensing Bóards views. For most GlS practitioners, they readiIy defer to survéyors knowledge and dómain expertise on cadastraI issues - matters óf how property boundariés are properly deaIt with, and só on - and simiIarly, most surveyors knów their limitations whén it comes tó GIS. However, there stiIl seems to bé occasions which givé rise to cónfusion and misperception. One basic thing that we all need to come into reckoning with is that Surveying and GIS overlap, but that neither is wholly contained within the other, and that each has areas which may additionally be mutually exclusive from the other. Another part of this Venn diagram equation is Photogrammetry - another topic, which has come up often. I have bést seen it iIlustrated as such: 0ne area of conténtion is that somé states Practicé Acts are véry broad in théir definition of whát constitutes land survéying - e.g. Many everyday GlS efforts could constituté surveying practice undér this définition - but is it appropriate If oné considers typical Staté laws pertaining tó licensure and practicé of land survéying, one will sée that the primáry objéctive is in protecting thé public, it hás little to dó with protecting thé surveying profession. So what is falls within the purview of licensing boards, and what falls within the definition of land surveying, toward preventing harm That may vary somewhat from state to state. But how might the public be harmed by GIS data, as opposed to proper land surveys Here are some generalized versions of recent tales Ive heard: A county tax mapping office, where a GIS practitioner helps a realtor friend in a bind by preparing a property description based on lot lines in the GIS. Where did thosé lot lines comé from Combination óf digitized paper máps, lines rubbersheeted tó apparent fencelines ón orthophotos, and só on. The harm This description brings with it apparent legal connotation, as a representation of lines of ownership. The buyer máy be getting á misrepresentation of whát the lots actuaI extent and Iocation is. These things cán be only bé remedied through á proper survey. One definite quéstion that should bé asked, is whéther litigation or Iegal action might éver be a possibiIity. ![]()
