Editors

Introduction to map editors

In a map window, map editors can be used to edit features of raster, polygons, segment or point maps.

With the pixel editor, you can:

edit the class names, IDs, or values of pixels in a raster map.

With the polygon editor, you can:

edit the class names, IDs, or values of polygons, and
create labels from polygons,
apply labels to polygons,
extract segments.

With the segment editor, you can:

insert segments and delete existing ones,
edit the class names, IDs, or values of segments,
change the shape of segments,
split and merge segments, and
check segments and polygonize segments.

With the point editor, you can:

insert new points and delete existing ones,
edit the class names, IDs, or values of points, and
move points to a new position.

The polygon, segment and point editor can be used with the mouse pointer on the screen, and with the digitizer cursor when a paper map is stuck on a digitizer tablet. To set up a digitizer and to start digitizing, see How to set up a digitizer.
