Process Description:
Authoritative data sources are identified through open source research. That data is then acquired and transformed into a usable data format. The properly formatted data then goes through preprocessing steps that includes a geocoding operation to give spatial context to the data. The data goes through further refinement using remote sensing techniques. After preprocessing, every record goes through a review process and each point is moved to a facility based on-entity location based on interpretation of the best available imagery and open source information. The DATE field indicates the date in which the review step took place.
