2011 Spring Seminar - Presented by the North Olympic Chapter
“Taming the Wild Loxodrome”
with Richard Dieckmann, Cadastral Surveyor
Oregon State Office, BLM
Friday, May 20, 2011 at the Holiday Inn Express Conference Center, Sequim, WA
Retracing cadastral surveys would be much simpler if only the earth were flat—but it isn’t—this is one reason why the Public Land
Survey System surveys were designed from the beginning to conform with curved surface of the earth. And, while plane surveying
techniques can be and are used to locate existent PLSS corners, problems arise when plane coordinate geometry is used to calculate
positions of lost PLSS corners as prescribed in the Manual of Surveying Instructions.
At this seminar, attendees can expect to learn…
•
•
•
•
…how geodetic based surveys differ from plane based surveys
…pitfalls to avoid when applying plane surveying computations to the solution of astro-geodetic based PLSS corner
restoration computations
…how computer software can be used to solve various PLSS restoration problems and provide astro-geodetically correct
solutions
…about current and future software platforms for PLSS restoration computations

SETTING UP AUTOCAD TO WORK WITH
CMM/GMM/ DXF FILES AND POINT Ids
1. Create the DXF exporting all points. In CMM/GMM, I recommend turning off the unknown
corner symbol, control symbol, error ellipses, and elevation text. These just clutter up the
drawing. For certain things you might want to leave them on.
2. In AutoCAD, open the DXF file created in step 1.
3. List a point and a point ID and figure out what layers they are on. Remember this.
4. I recommend using the CHANGE command, selecting everything in your drawing, and
changing the “Properties” to move all of the points to the average elevation of your project.
5. Run the following CAPD commands in this order (Always turn off OSNAPS before running
these commands!!!):
GETPRO - Sets up your projection information. Should be same as CMM
CADINIT - Sets up default layer, font, and line type info.
GEOPREFS - Turn on the “Prompt for Point ID” option
MVNAMES - Moves insert point of point id to the point
REPIPG - Replaces the text point id with an IDGEO block
CHGSL - Select all the new points (just type ALL if you don’t have a bunch of other text)
and then change the style to V100 or something else that you can see, you will now be
able to read the point id’s.
6. You may now use CAPD commands such as ITRAV, TRAV, etc. to begin and end at the
correct points according to point id. You will have an option designated with the # symbol on
the prompts for selecting beginning and ending points. Enter the # and you will then be
prompted for Point ID.
7. It is recommended that you change to a layer separate from the points or text etc. (you can
make a new one if you want to), before drawing lines. Once you have drawn the lines you may
freeze the layers with points and point id’s. If you want to keep the point id’s visible that you
have drawn you lines to, you will need to put them on a separate layer.
8. You can change the size of the lettering associated with the point id by using the CHGSL
command. This will also change the layer they are on if desired.
***This is just a brief outline to get you started. You can download the latest routines off the
internet at http://www.blm.gov/narsc/lisp/
Setting up OR/WA CAPD
This document is to show and test the installation of the CAPD folders into AutoCAD 2008. It
will show how to point AutoCAD to the right Cadastral Automated Plat Drafting folders, as well
as adding all the necessary AutoLISP routines.
Go to S:\957\CAD PLATS\AutoCAD_drafting_tools and standards
Copy both the CAPD_OR-WA & CAPD-National-version2006-March folders into your
c:\tmp folder.
Open AutoCAD
On the AutoCAD menubar under Tools, at the very bottom of this dropdown you will find
Options. Select it.
Select the Files tab.

selected files.
Repeat this 8
more times to

found here.
Now browse to the C:\tmp\CAPD_OR-WA\lisp folder.
You will need to repeat the same loading procedure as the above and load all the .lsp files found
here in this folder.

Tangent Plane Coordinate projection
RHCMM State Plane Coordinate file (NEZ) to TDS foresight and on to Nomad Survey pro.
Quasi local tangent plan coordinates. Compute and display in True Bearings and project/ground
dist.
The following steps are for importing CMM State plane Coordinate files into TDS nomad SurveyPRO
using TDS foresight DXM. By design, TDS applications have any number of ways to get to the same
solution. This is just one way to accomplish this. Once a user is familiar with the application they
may find a more efficient process.
---------------------------------------------------------------------------------------------------------------(STEP 1)
Export CMM Coordinate data to a file for TDS DXM
In CMM project
File
Export
Export Northing, Easting, elevation, (.NEZ) **
Browse to cmm_project .Def
Open
OK
( .nez file created in cmm_project folder)
** or “user defined export” project.csv
--------------------------------------------------------------------------------------------------------------(STEP 2)
Set up “project” in TDS Foresight DXM
Start Foresight DXM.
Start TDS survey works
Foresight DXM
Create Project DXM project
Browse to and name “name.pro”
In plan view
Project
Project settings
-vitals (to expand point Id field)
MAX objects = 1,000,000
MAX alpha = 1,000
OK
Project
Projection setting (left plan), no projection
( ) use a projections (don’t check the box, no projection)
CLOSE
Note; it is best to start “new project” for each Cadastral group. You can have muliti “jobs” in a
project and import CMM project data regularly for a rapid export to nomad TDS, by returning to
step 3. All these project settings will remain default for this project for additional/ new exports
from CMM and it will “X overwrite all existing point with the same name” for a quick export to the
nomad.
---------------------------------------------------------------------------------------------------------------(STEP 3)
Import CMM Coordinate data file for TDS DXM
In Foresight DXM, project name.pro
File
Import
ASCII (txt,ect)
Browse to CMM_project.nez file
Open
Specify character separation
X .commas
Next
Specify coordinate data value column
. . Point name, northing, easting, elevation
Next
Point Name Option
X .overwrite all existing point with the same name
OK
Finish
overwrite
Review the transfer list for completeness………all points?
Note; at this point, this TDS Foresight project data precisely matches your CMM project (grid
coordinates). All these project settings will remain default for this project for additional/ new
exports from CMM and it will “X overwrite all existing point with the same name” for a quick export
to the nomad.
----------------------------------------------------------------------------------------------------------------
(STEP 4)
Scale and Rotate Coordinate data in TDS DXM, (will resemble local tangent plane coordinates)
In Foresight DXM, project name.pro
Adjustment
Translate/rotate/scale
In the left pane (adjustments)
Select objects
Select All
Scale
Reference location
>..User - defined
>..point (point ID) * near project center
** Northing (“scale factor”) from CMM or Corpscon
** Easting (“scale factor”) from CMM or Corpscon
** NOTE: inverse of Combined Factor gives better results
SCALE
* click once only
Rotate
Rotation Angel
>..point (point ID) * near project center
>..Simple
..dd.mmss “convergence” or “grid rotation” from CMM or Corpscon
ROTATE
CLOSE
Note; most of these project settings will remain default for this project for additional/ new
exports from CMM and it will “X overwrite all existing point with the same name” for a quick export
to the nomad.
---------------------------------------------------------------------------------------------------------------(STEP 5)
Import DXM/CMM Coordinate data file to TDS nomad
In Foresight DXM, project name.pro, Plan view ( with Namad connected to PC and powered up)
Transfer
Create job for data collator
Transfer settings
Windows CE (ranger, recon)
Active Sync
Surveypro CE V3.5 or later
OK
In left pane (create job for Data collector)
Select objects
Select all
Job name
Name XnameX
Next
Set remote folder (Survey Pro Jobs)
SEND
SEND
CLOSE
File
Save project
Your complete CMM project data is now in the TDS nomad survey pro. The project is in a local
tangent plane projection and all computation and display in near to True Bearing and Project/Ground
Distance.
This is a “Quasi” PLSS datum/projection. Validation with a one section project, comparing lines one
mile in length, the bearings were Less than 20” of true and distances were Less than .20 ft. of true
ground. For Larger projects, it would be prudent to “Rotate and Scale” near the current project
work. The closer to the origin of the rotation and scale and the shorter lines, the truer the data…
