Abstract

Apparatus for encoding in a digital form information to produce a data base descriptive of a land mass or the like. The information being encoded is simultaneously displayed, and compared with the source of the information which may be a map, photograph, etc.

Claims

1. A digital data base generator comprising:

memory means for storing in digital form a data base descriptive of a selected land mass;

display means for displaying a selected portion of the data base in graphic form;

comparison means for comparing the displayed selected portion of the data base with a graphic depiction of land mass information from another source related to said selected portion of the data base; and

control means for modifying said data base.

2. A digital data base generator in accordance with claim 1 wherein:

said comparison means includes a 45* beam splitter so that the image of the display and the image of the graphic depiction of land mass information from said other source can be placed in overlying relationship.

3. A digital data base generator in accordance with claim 1 wherein:

said control means includes a control for moving a cursor to a desired location on said display means.

4. A digital data base generator comprising:

memory means for storing in digital form information describing land mass points in the data base;

means for displaying a selected portion of the data base in graphic form;

means for simultaneously displaying, in an overlying fashion, a graphic depiction of land mass information from another source relating to said selected portion of the data base; and

control means for modifying said data base.
