In the course of browsing a map the user can add new features as well as change and remove the existing features. Two editing methods can be applied:
adding and changing features specifying coordinates of characteristic points of the feature;
adding and changing features in the mode of interactive drawing using a mouse.
There is also a set of convenient auxiliary operations of editing such as combining and intersecting features, building buffer zones around features, transforming area features into linear ones, etc.
ObjectLand provides the possibility to transform coordinates of all or part of features according to affine or non-linear rule assigned by specifying of old and new coordinates for the set of control points.
ObjectLand allows performing input of features of GDB map from a paper medium (digitizing of maps) using digitizers of different models.
