Dynamic shape approximation

摘要

Implementations of dynamic shape approximation are described. In one technique described herein, a feature of interest in a first coordinate reference system is accessed and at least a portion of the feature is identified and converted to a second coordinate reference system. In one implementation, the size of the portion is chosen such that the portion can be represented in the second coordinate reference system with an acceptable amount of error.

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.
