snippet: Two foot contours created by Aero graphics back in 1997. DIGITAL PHOTOGRAMMETRY ACCURACY DECLARATION Digital map data contained in these files was collected by photogrammetric methods. Reasonable procedures have been adhered to with regard to photo scale, equipment, calibration and operator experience to achieve the accuracy required by the scope of work. The accuracy of this data presumes that there is no discernable error in the ground control survey. Aero-Graphics cannot be responsible or liable for the further manipulation and plotting of design maps by the user's software. The data collection procedure is designed to meet or exceed the requirements of United States National Map Accuracy Standards. 1. Horizontal accuracy. For maps on publication scales larger than 1:20,000, not more than 10 percent of the points tested shall be in error by more than 1/30 inch, measured on the publication scale; for maps on publication scales of 1:20,000 or smaller, 1/50 inch. These limits of accuracy shall apply in all cases to positions of well-defined points only. Welldefined points are those that are easily visible or recoverable on the ground, such as the following: monuments or markers, such as bench marks, property boundary monuments; intersections of roads, railroads, etc.; corners of large buildings or structures (or center points of small buildings); etc. In general, what is well-defined will also be determined by what is plottable on the scale of the map within 1/100 inch. Thus, while the intersection of two roads or property lines meeting at right angles would come within a sensible interpretation, identification of the intersection of such lines meeting at an acute angle would obviously not be practicable within 1/100 inch. Similarly, features not identifiable upon the ground within close limits are not to be considered as test points within the limits quoted, even though their positions may be scaled closely upon the map. In this class would come timber lines, soil boundaries, e
