Abstract
Apparatus and methods useful in surveying to provide information rich models. In particular, information not readily or possibly provided by conventional survey techniques can be provided. In some versions targets provide reference for baseline positioning or improving position information otherwise acquired. Scanning may be carried out in multiple locations and merged to form a single image. Machine mounted and hand mounted scanning apparatus is disclosed.
Claims10
A method for locating a position within a scanned zone, the method comprising:
- scanning the position of a target within the scanned zone;
- sending a signal to the target including information regarding the position of the target within the scanned zone.
A method of producing a three dimensional scan of land comprising:
- imaging the land by illuminating the land with radar at different locations;
- receiving radar reflections from the land at the different locations;
- creating, using the radar reflections, a three dimensional image of the land;
- determining from the radar reflections characteristics of the land in addition to its physical configuration.
