TPC Desktop Introduction 19
Introducing Point Codes and Drawing Codes
TPC Desktop provides two ways to draw your maps from your field data
–
Point Codes
and
Drawing Codes
. You are free to use either one.
Point Codes
are number codes or abbreviations used to identify points in the survey. They are
typically short to facilitate coding in the field and may or may not be descriptive of the points (i.e.
121=Oak Tree, 245=3 port fire hydrant, TOE=toe of slope, CLF=Chain Link Fence, etc.).
TPC uses the codes to sort points into traverses. All the points with the CLF code end up in the
Chain Link Fence traverse, all the Oak Trees are in their own traverse, etc. When you plot the
individual traverses, you’ve got a site map.
Point Codes
are only available in the Professional Edition.
Point Code manager
The Point Code manager manages your point
codes. You can create traverses for all the
codes or just the ones you want. You can
standardize your
Point Codes
plus easily add
any new ones you used that day.
Then assign Drawing Settings to each code,
telling TPC which symbol, color, annotations
and so on you want to use when you draw each
code.
Creating Traverses from Point Codes
The traverses you create from point codes can
also be updated to include new points you add
to the survey. Just choose
Tools

Sort Points
Into Traverses by Code
. If you collect more data,
you can easily add the new points to the existing
traverse by choosing
Tools
|
Update Existing
Point Code Traverses
.
Drawing Codes
TPC Desktop also understands
Drawings Codes
like .BL for
Begin Line
and .EL for
End Line
.
They are fully customizable and provide a field to finish alternative to
Point Codes
. Your field data
can incorporate
Drawing Codes
either in the point descriptions or Note records.
