Terrain map updating system
First Claim
1. A terrain mapping system, comprising:
- at least one sensor configured to gather a plurality of current points defining a current surface of a site;
a database containing a plurality of previously-gathered points defining a previous surface of the site;
a controller in communication with the at least one sensor, the controller being configured to;
compare a height of at least one of the plurality of the current points to a height of a corresponding at least one of the plurality of previously-gathered points;
determine if an update to the database is warranted based on the comparison; and
update the database if it is determined that an update is warranted.

Abstract
A terrain mapping system is disclosed. The system has at least one sensor configured to gather a plurality of current points defining a current surface of a site and a database containing a plurality of previously-gathered points defining a previous surface of the site. The system also has a controller in communication with the at least one sensor. The controller is configured to compare a height of at least one of the plurality of the current points to a height of a corresponding at least one of the plurality of previously-gathered points and to determine if an update to the database is warranted based on the comparison. The controller is further configured to update the database if it is determined that an update is warranted.

11. A terrain mapping system, comprising:
-
at least one sensor configured to gather a plurality of points defining a surface of a site; and a controller in communication with the at least one sensor, the controller being configured to; identify points among the gathered plurality of points that do not define terrain of the site; filter from the gathered plurality of points the identified points that do not define the terrain of the site; and generate a map of the terrain based on the filtered gathered plurality of points. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of mapping terrain, comprising:
-
gathering a plurality of points defining a surface of a site; identifying points among the gathered plurality of points that do not define terrain of the site; filtering from the gathered plurality of points the identified points that do not define the terrain of the site; and generating a map of the terrain using the filtered gathered plurality of points. - View Dependent Claims (18, 19, 20, 21, 22)
