===== How it works =====

This option allows you to shift the rows frontally or laterally according to the antenna configuration when recording points.

The option is only available **when at least one map is loaded in the application**.

===== Application =====

When the option is started, a window opens allowing you to :
  - Select the project to be shifted
  - Enter offset parameters
    * The front offset of the antenna in relation to the row (positive if the GPS is at the front of the seeder).
    * The lateral offset of the antenna in relation to the row (positive if the GPS is located on the right of the seeder).
    * Whether or not the entire map is offset to the same side.
      * If this parameter is enabled, the offset will be effective relative to the map background and not to the row.
      * Otherwise, each row will be shifted so as to create a map corresponding to the GPS track if it had been placed at the level of the sowing heads.

To illustrate the differences in shift depending on the "**shift all map to the same side**" parameter, here's a comparison:
  - Original map
  - Map with 20cm lateral offset, no same-side offset
  - Map with 20cm lateral offset, same-side offset

The differences between maps 1 and 3 can be seen in the white object.

The **D** keyboard shortcut also starts the tool.
