This feature class was compiled using several datasets that had been previously been maintained by the Dauphin County Emergency Management Agency (EMA) and referencing 2003 PAMAP aerial photography. The existing datasets were combined into a single dataset which was then updated to include all the buildings 100 sq ft or larger that were visible on the aerial imagery. The featue class is edited on a case-by-case basis, based on the collection of new building information submitted by EMA or Dauphin County IT or through examination of updated aerial imagery.
