Fast grid classification

This functionality is intended for advanced users; it is configured manually.

It is possible to define hot keys that can be used to assign values to a specific attribute or to move within points in the grid. After opening Field-Map window and making Grid layer active it is possible to click Alt + any assigned key in order to invoke desired action. For instance Alt+F will jump to the first point which has not been classified yet. Alt+1 will assign attribute value to it. Alt+N will move to the next point. Alt+I will show the information about number of points to be finished.


Steps to establishing this functionality

• Create a control XML file manually.

• Add a section with a reference to the control XML file into the Project.ini file.


The control XML file must be located in the root directory of the working project. You can use any name of the XML file. The Project.ini file is stored in “Misc” folder.


Example of the control XML file (FastClassification.xml)

<?xml version=”1.0” encoding=”UTF-8”?>
