Attribute accuracy is described, where present, with each
attribute defined in the Entity and Attribute Section.
Point features present.
(Information in wordy narrative form describing omissions,
selection criteria, generalization, definitions used, and other
rules applied to derive the data set)
(An explanation of the accuracy of the horizontal coordinate
measurements and a description of tests used, if any, to
determine horizontal positional accuracy. This is different
from horizontal resolution as reported in the DOC file.
Positional accuracy defines how correctly the digital features
match real-world features and woiuld be related to the concept
of the National Map Accuracy Standard -- xx% of well-defined
point features fall within xx units of their true position.
The resolution is the smallest unit of measure the GIS can
reliably manage without truncation or rounding.)
(The same as above, but for vertical information that may
be encoded with the 2-D features such as cell or contour
estimates of a vertical dimension. A description of the
contour interval of input data and its basis could be described
here.)
