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 |
