Cadastral Tools


Intersecting Line Tool

The Line Intersect Tool uses one line as the "sight" line and another as the "target" line. The tool calculates a line of same bearing as the sight line to intersect the target line. The distance from the end of the sight line to the target, the intersection coordinates, and the measures of the "split" target line are reported to the Tool Results table. Graphics show the intersecting line, the point of intersection, and distances on the Main Map. Read more...

Basic Use

  1. click to start the tool
  2. Select the sight line.
  3. Shift+ click to select the target line.
  4. Ctrl+Shift+ click to calculate

Results are shown in the Tool Results window and graphics on the map.

Complex fabrics can have many overlying lines, and selection is sometimes difficult. Use the Fabric controls to show only the plan or plans needed.


Selecting Lines

For complex situations, consider the following:

Advanced Selection Operations

  1. click on a line to start, or use a selection box.
  2. Shift+ click to add another line
  3. Ctrl+ click to remove a line from the selection
  4. If you want to add a shorter line under the selected lines, Shift+ click over a section of line.
  5. Remove lines you don't want from the selection using Ctrl+ click on a collinear segment that does not contain the desired lines.
  6. You can use a selection box (click and drag), with Ctrl and Shift combinations.

Tip! This tool requires selection of lines from the fabric lines layer shown on the map. If your site does not use views with a lines layers as part of the standard views, there may be special views may be available in the theme control which you can apply to show the lines. Ask your site expert if there are any available.


Details

The tool was created to allow measures from a recent survey to lines in a prior survey, by extending a line in one to intersect a line in the other. The quality of the results depends on the coordination/adjustment of the fabric. Calculation uses line endpoint fabric coordinates to derive each line's parameters in fabric space. It does NOT use the recorded measures in the plans! Therefore, if you use this tool on lines from the same survey, the results will not match calculations done using recorded line measures.

Here are a few points about how it works:

  1. Calculations are made from inverted lines using fabric coordinates.
  2. You must have sight and target lines that are NOT connected.
  3. Sight line must be selected first.
  4. If multiple lines for target and or sight lines are in selection
    1. calculation will remove duplicate lines
    2. calculation will use (prioritize) boundary lines
  5. Depending on jurisdiction, grid coordinates are converted to ground using point scaling factor.

Warning: The quality of the resulting calculation will depend on the quality of the fabric coordination or adjustment.
