Automatic polygon features separation

 

If you need to separate your polygons into simple plots of the same area, you can use the Automatic polygon features separation tool.

 

Run the tool and fill in the appeared dialog:

 

 

Separation data sources – polygon layers in your project. By default all of them are selected for separation. But you can also work with the selected features of the layer you need to separate.  

 

Separation settings – user settings that specify the following values:

o Area of plots with the dropdown list of measurement units;

o Permissible error – the tolerance for specifying separation parameters;

o Options of unifying polygons before separation;

o Automatic calculation of general direction of separation.

 

Transfer attributes values:

o Apply to all features – an option provided for transferring the source attribute table values to the output polygons;

o Create features with empty values: if you enable this option, then the attribute tables of the selected layers will be empty.

 

The below figure demonstrates the result of separation with the following parameters:

o the required features are selected on the map;

o the area of the plots is 20 hectares with the permissible error of 0,2 hectares:

o all options of unifying polygons are enabled;

o general separation value is 45 degrees;

o create features with empty values option is enabled.

 

 

To number the output plots press the Automatic numbering button in the Features numbering tool dialog.
