Copan News

Regarding Copan Lite for Windows 10.09.
Resections
Renamed as FreeStations
The Field Resections module is now referred to as Field FreeStations module.
The idea is to help prevent people confusing modern resections, involving angleanddistance shots (what Copan actually processes),
with classical resections, involving angles only (what Copan does not yet process).
Projection Scale Factor
Renamed as Scale Factor
Wherever a Projection scale factor was referred to, it is now referred to as Scale Factor.
Copan's treatment of it is the same — horizontal distances are scaled by the SF — and you are responsible for appropriately combining your projection and sealevel scale factors.
Coordinate Transformations Added to Import / Export
You now have the option — during Export to Ascii file,
and Export to Total Station file — to
transform the exported coordinates.
Whether you wish to convert between coordinate systems or apply a scale factor or a units factor, just click the new
Yes button under
Apply Transformation and enter your parameters. The coordinates will be transformed upon export; the coord
file points themselves remain unchanged.
You can do the same during an Import from Ascii file (i.e., transform incoming points before they're saved to the coordfile).
Improvements to Coordinate Transformations
 Wording within the Coordinate Transformation modules has been changed to clarify the 2D / 3D nature of the transformations:
entered parameters can include Zscale and Zshift, while estimated parameters exclude Zscale and Zshift.
 The precision of listed rotation angles has been maximized.
Stored or computed rotation angles were always maximized — angles as listed were rounded, however.
 1/SF and A buttons have been added to the Transformation by Parameters dialog to quickly invert the scale factor and negate the rotation angle, respectively.
 A bug in reporting the polynomial form of the estimated transformation (by control points) was fixed.
The estimation and the surveyorfriendly reporting of the transformation were always correct — the listed polynomial form was not, however.
Scaling of ExtendedCode Sizes Added to Transformation
(While this option has been added to the Transformation modules, it gets its own heading here because it doesn't necessarily concern coordinates.)
The following change
only applies to you if
your points have
extended code dimensions (i.e., they have codes that include sizes for trees, holes or culverts
according to the specs in
§ Copan Point Codes),
and if
your current Codes Table is properly setup and its path is valid:
The dimensions within any extended point codes will now get scaled by the given Units Factor during coordinate transformation.
For example, if your coordinates are in metres and your manhole depths and tree trunk diameters are in centimetres, then transforming (by parameters) with UF=3.28084 will not only convert your coordinates to feet, but also convert your manhole depths and tree trunk diameters to hundredths of feet.
Improvement to COGO Calculations
Azimuth Correction and Scale Factor boxes (and corresponding AC and 1/SF buttons) have been added to CoGo (but not to CoGo Lite).
Enter an Azimuth Correction and Apply it to the Bearing, either before a Calculation or after.
Scale Factor works the same way as Units Factor (enter a value and Apply it to the Distances and Offsets).
Improvements to Multiple Inverse Calculations
 Scale Factor and Units Factor boxes (and corresponding 1/SF and 1/UF buttons) have been added to Multiple Inverses. If you enter nontrivial factors, your calculation listings will include both coordinatebased and converted distances.
 An Azimuth Correction box (and corresponding AC button) has also been added for the Bearing & Distance case. If you enter a nonzero value, your calculation listings will include both coordinatebased and converted bearings.
 A Left/Right option has been added to the Angle & Distance case. The default angleright option yields positive, clockwise angles while the angleleft option yields negative, counterclockwise angles.
Improvements to the Map Trav
trio of Modules
Wherever they weren't available before, Azimuth Correction, Scale Factor and Units Factor boxes (and corresponding AC, 1/SF and 1/UF buttons) have been added to Map Traverse Adjustment, Map Traverse Checking, and Inverse Map Traversing. If you enter nontrivial values, your calculation listings will include converted bearings and distances.
Improvements to the Field
trio of Modules

An option to export any field data to a GeoLab IOB file has been added to Field Data, Bearings and Resection Processing.
If you have the BitWise Ideas network adjustment program GeoLab and need to process survey data that would be awkward to properly process within Copan but otherwise can be put into Copan, you can now load them from a total station file or manually enter them, then just click Export... (in the Field Data File section) and Copan will let you save them to an IOB file.

As you enter an At, Ref or To point number, its file status (ie, whether it exists) is now displayed.

The option to use point Names has also been added to the
Field
modules. It was possible to add alphanumeric names (in adition to required numeric IDs) to points within other modules and now you can do it in the Field modules; the Observations section now has a Name box and a shot
data line now has an optional nam=point name
component.

The chance of Copan (mis)interpreting an intended closing angle observation either as an invalid observation or as a REM (remote elevation measurement) when a VC is present has now been greatly reduced.

1/SF and AC buttons have been added to the ProjectInstrumentScales dialog to quickly invert the scale factor and negate the azimuth correction, respectively.
Improvements to File Locations
 The default Initial Project Folder location has been changed from .../My Documents/ to .../My Documents/Copan/. Your own setting for this will be unchanged, though.
 The default Auxiliary Files Folder location has been changed from ...Program Files/Copan version/ to .../My Documents/Copan/Auxiliary Files/. Again, your own setting for this will be unchanged, but N.B., if you were in the habit of moving your auxiliary files folder from one installation of Copan to the next, you are advised to move it one last time to .../My Documents/Copan/ or to any other fixed location, and then never be bothered by having to move it again!
If you never used any auxiliary files
(e.g., codes.txt)
it doesn't matter either way.
 While the default User Manual Folder location has not changed, Copan now tries to keep the version of the user manual that it uses synchronized with itself (the program version). And you now have the option to tell Copan to use the latest version of the user manual on the UGL website. So even if you choose not to install the user manual, you can now have Copan accessing it via the Internet.
 Finally, your User Settings Folder location has been added for your information.
Most of you will never be concerned where this is or what's in it, but if you are, there it is.
ΔZ Display Added to Measure
Did you know about the rightmouse popup menu item Measure?
If you click the rightmouse button, choose Measure from the popup menu, click on the graphics screen, and move the mouse around, the bearing and distance (as Bng:
bearing Dis:
distance) of the elastic line are displayed in the middle of the status bar at screen bottom, along with the delta north and delta east (as n:
ΔN e:
ΔE).
Also, if the ends of the elastic line are near coordfile points, it will snap to those points giving you an instant inverse calculation without the need to open the Cogo dialog.
Now the new part: If the two coordfile points at the ends of the elastic line are 3D, the display will also give you the delta elevation (as z: ΔZ) between the two points.
