Project point method for adding points can be used in conjunction with any range finder which measures horizontal distance and true bearing to a target.
In the example below we will construct a line using the ‘Project Point Method’ but it can be used with any type of geometry type in MapIt.
1. Enable ‘Project Point Method’
To be able to use the ‘Project Point’ method for add point action you need to go to ‘Survey Settings’ and switch on the ‘Distance & Bearing’ option.
2. Setting the BASE point.
Assuming that you have already a line layer set as active please add new feature and press ‘Add Point’ button on the map toolbar. When the ‘Project point’ (Bearing & distance ) method is enabled when the button is pressed a dialog window will be displayed allowing you to place new point.
To set current location (this can be either the GPS position when centre on GPS is on or current cursor location) as a base please check option ‘Mark this point as Base‘ and set bearing and distance to 0. then press save.
New point will be added to the map.
If you would like to exclude this point from the line, press the back button – that operation will remove the point, however the base point will be still remembered by the system.
Please note you can have only one active base – and this base can be used across multiple layers and features.
3. Adding subsequent points
When the base is set you can press the ‘Add point’ button and add new points providing distance & true bearing. Please make sure ‘Use base location’ is ticked as a source point.
Using the method above you can add multiple points to get the line built.
