Data believed to be complete and accurate as of the time period cited. Subject to change. In process of validation by source and/or responsible agency.
Data believed to be complete and accurate, except for areas of DC deemed sensitive for national security purposes. Validated by source and/or responsible agency.
Validated by source and/or responsible agency. The horizontal accuracy is guaranteed to meet National Map Accuracy standards which calls for 90% of well defined points to fall within .85 meters of true position. This accuracy was verified by the completion of a fully analytical aerotriangulation adustment which resulted in an RMSE of 1 part in 10,000 which is recognized as necessary to achieve the accuracy requirement.
In process of validation by source and/or responsible agency.
Aerial photography is from 1995. More info to come.
