1. A method comprising:

  • providing a feature that comprises coordinates defined with respect to a first geospatial coordinate reference system;

    displaying the feature on a monitor at an approximate location with respect to a second geospatial coordinate reference system; and

    responsive to zooming, re-approximating the location of the feature with respect to the second geospatial coordinate reference system via a linearized curve, the linearized curve being determined in part by conversion of at least one of the coordinates of the feature defined with respect to the first geospatial coordinate reference system to at least one coordinate defined with respect to the second geospatial coordinate reference system.
