The University of New Hampshire started our journey of Indoor GIS mapping more than a decade before ArcGIS Indoors was a glimmer in ESRI’s eye. We’ll discuss our early days of CAD georeferencing and conversion utilizing model builder, python and currently FME as well as poor CAD drafting versus the nobel sensibilities of GIS and realizing the third dimension. Furthermore, revelations on early indoor asset data collection via old school printed maps to Collector and finally Field maps and aligning to the ArcGIS Indoors schema. We’ll discuss the constant struggle between aligning our ever changing physical infrastructure to our “digital twin” or vice versa, whether it’s discovering “new” rooms to physical signage mismatches. Join us as we dive into the trials and tribulations of Indoor GIS mapping through the years and what it might hold for the future of space management and beyond at UNH.
