Land Surveying and GIS – What, When, and Why!

Start Date
End Date
A presentation for non-surveyors about the different types of land surveys and how to go about acquiring those services necessary for specific projects. Topics covered can include property line retracement surveys, data accumulation (topographic utility) surveys, ALTA/ACSM title insurance surveys, construction surveys, high definition (laser scanning) surveys, high-precision surveys, interior building surveys, aerial photogrammetry controls and surveys, bridge and infrastructure surveys, historic harbor line and wetlands delineation surveys, hydrographic surveys, railroad right-of-way surveys, route surveys, and GIS. We’ll discuss what questions to ask in the proposal phase of the project to obtain a survey that meets your needs without over- or under-scoping. We will also discuss various technologies and methods available, such as laser scanning and GIS, and how their appropriate use can impact the quality and cost of the final survey deliverable. Not all surveys need to be performed to the same level of accuracy, and understanding the accuracies involved will determine the proper technology and approach for your project.
