Code Library

This file defines the point codes to be used to auto create strings and assign symbols to points
Click here for more information.

Check Codes

Tick to check every point code is a legal code in the Code Library File
This is used to detect point coding errors and to enforce coding standards.

Form Strings

If this options is selected, the program will form strings joining points with the same codes.
It will use the Code Library to place the strings on certain layers.
It will also do Point Symbolisation - assign symbols to points based on their code using the rules defined in the Code Library.
Note: It will also do Point Code Translation BEFORE Forming strings or point symbolisation

Listing

Enter a listing filename if one is required.

Tip - Automatic Layer Creation

The Code Library string/point formation will automatically create the layer if the
layer does not exist and will give the layer the string/point attributes (colour,
line style, thickness, symbol, symbol size etc) as defined in the Code Library file.

If a coded string/point attributes are the same as the layer attributes,
the string/point attributes are set to 'BYLAYER' so that when the layer attributes are changed later,
the string/points on that layer will use the new layer attributes.

Field Obs Reduction

You can enable point averaging for muiple observations to the same point.
Tick "Avg Obs" in the Session Properties
When ticked, during reduction it will average the reduced co-ords with the existing pt co-ords.
If the diffs are outside Session tolerances, it will not average them and will show the Differences.
If not ticked, ab obs to a point will overwrite the existing co-ords. Last obs wins.
