Using the Transform
panel with Tables
on a geom field in a table is
equivalent to applying the Transform panel to a Drawing and using the geom field in
the drawing. See the Transform
Templates - Drawings topic for a discussion of transforms
that can be applied to geom fields
in tables.

See the Transform
panel and Transform
Templates topics for use and for links to lists of templates
for other data types for tables and use of the Transform panel with other
components, such as Drawings
and Images.

Notes

Distances - Some templates use
combo boxes within which we can specify a distance. The distance
units used in such boxes are the units of measure specified for the coordinate
system (projection) utilized by the source geom
field. The quickest way to see that is normally to right-click on the table involved
in the Project pane and to choose Properties.
The FieldCoordSystem.Geom
property will show the coordinate system used for the Geom
field. Right-clicking
onto the value cell of that property and choosing Edit
will show the entire contents of the value, including the unit of measure
used. If the projection in use uses meters as the unit of
measure than whatever we enter into Distance
for, say, creating a buffer will be a number in meters.

We must, of course, pay attention to what we are doing given that many
data sets use Latitude/Longitude
coordinate systems which use geographical degrees
as a unit of measure. If we give a Distance
of 1 in such cases we are telling
Manifold to use a distance of 1
degree, which is about 111 km
or 69 miles at the Equator and
a different value elsewhere.

It is inefficient to use Latitude/Longitude
when we need to do anything involving distances, so it makes sense to
quickly re-project any such data into a coordinate system that does not
use degrees.
