The dataset was updated for the Charles County government to support its internal and external activities. The County government last updated planimetrics in 2014 and partially updated in 2017. The primary objective of this project was to update the planimetrics using the Maryland state imagery flown in 2020.

2020 orthoimagery
Topology was validated to ensure no overlap or intersection of data as required, particularly among impervious surface features.
This dataset was updated based on 2020 orthoimagery using 2D compilation techniques for Charles County, MD. Existing, unchanged features were not modified to match the 2020 imagery.
