Control (known) coordinates are described by the start-end pair tag
`<coordinates>`

. A series of points with known coordinates can be
defined using the `<point />`

tag. The variance-covariance matrix
for the entire set of points can be created with a single
`<cov-mat>`

tag. In the `<point />`

tags, a point
identification (ID) and its coordinates (x, y and z) must be listed.
Although the order of the `<point />`

tag attributes is irrelevant
in the corresponding variance-covariance matrix, the expected order of
the coordinates is x, y and z (the horizontal coordinates x, y, or the
height z might be missing, but not both). The type of the points may be
defined either directly within the `<coordinates>`

tag or outside
of it.

<coordinates> <point id="1" x="100.00" y="100.00" /> <point id="2" z="200.00" y="200.00" x="200.00" /> <point id="3" z="300.00" /> <cov-mat dim="6" band="5" > ... <!-- covariances for 1x 1y 2x 2y 2z 3z --> </cov-mat> </coordinates> |
