Red lining an area on the map

PTMapper has 3 methods for creating a red line (or any other colour) around an area of land.

 

Method 1

This method puts a simple line on top of the boundary for your chosen area, by making a copy of the area that you select and putting the copy on your new layer. Your new line will sit on top of the original area.

  1. Create a new layer – choose a suitable line colour, thickness and line style if required (e.g dotted or dashed).
  2. Unlock the layer for the field (or area) that you wish to red line.
  3. Select the field by clicking on or inside it.
  4. Click the “Copy objects to current layer” button – or click “Objects” on the menu bar and then “Copy to Layer”.
  5. Click the “Deselect” button.

 

Method 2

This method puts the line immediately inside or outside the boundary of your chosen area, by creating a parallel line (buffer strip) around your chosen area.

  1. Create a new layer – choose a suitable fill colour and line colour, thickness and line style if required (e.g dotted or dashed).
  2. Unlock the layer for the field (or area) that you wish to red line.
  3. Select the field by clicking on or inside it.
  4. Click the “Draw parallel lines or buffers” buttonĀ  or click “Tools” on the menu bar and then “Parallel lines”.
  5. On the left of the screen select either “Draw inside” or “Draw outside”.
  6. Tick the “Create a closed border area (buffer)” box.
  7. In the “Spacing” box type the width of your line in metres.
  8. Click “Draw parallel line”.
  9. Click the “Deselect” button.

The line thickness will be based on the figure you typed in the “Spacing” box. This technique can also be used to create field margins or buffer strips.

Method 3

  1. Unlock the layer for the field (or area) that you wish to red line.
  2. Select the field by clicking on or inside it.
  3. Click the “Draw parallel lines or buffers” buttonĀ  or click “Tools” on the menu bar and then “Parallel lines”.
  4. On the left of the screen use the small arrow buttons to increase or decrease the figure next to “Red line on width of page (mm)”.
  5. This also adds a new layer called “Red Lining”, which has a red colour scheme. This can be changed if required.
