Digital map having user-defined zoom areas
First Claim
1. A computer hardware logic for displaying a computer-generated geographic map on a video display, the computer hardware logic comprising:
- a receiving logic for detecting an input signal for initiating a map zoning mode for an initial computer-generated geographic map, wherein the map zoning mode prevents zooming of all of the initial computer-generated geographic map;
a zooming logic for zooming multiple user-selected areas on the initial computer-generated geographic map, wherein said zooming generates a unique zoom window for each of the multiple user-selected areas, wherein each said unique zoom window displays and overlays an enlarged view of a corresponding user-selected area, from the multiple user-selected areas, over the initial computer-generated geographic map, wherein the multiple user-selected areas are each a different singular point on the initial computer-generated geographic map;
a persistence logic for persistently and simultaneously displaying all of the multiple zoom windows over the initial computer-generated geographic map;
a cursor movement detection logic, wherein the cursor movement detection logic detects a distance between a user dragging a clicked mouse cursor from a user-selected singular point on the initial computer-generated geographic map to a final resting position of the mouse cursor, wherein the dragged distance automatically determines a size and zoom level of a zoom window;
a zoom window repositioning logic, wherein the zoom window repositioning logic detects a pre-defined type of information displayed on the initial computer generated geographic map; and
automatically repositions the zoom window such that the zoom window does not overlay and obscure the pre-defined type of information displayed on the initial computer-generated geographic man;
a zoom window visual encoding logic, wherein the zoom window visual encoding logic alters a physical appearance or a shape of a border of the zoom window in accordance with a unique condition of roads depicted within the zoom window; and
a selective zooming logic for selectively zooming each of the multiple zoom windows to different zoom levels.

Abstract
Computer hardware logic displays a computer-generated geographic map on a video display through the use of a receiving logic and a zooming logic. The receiving ic detects an input signal for initiating a map zoning mode for an initial computer-generated geographic map. This map zoning mode prevents zooming of the entire initial computer-generated geographic map. The zooming logic zooms a user-selected area on the initial computer-generated geographic map, thus generating a zoom window that displays and overlays an enlarged view of the user-selected area over the initial computer-generated geographic map.

7. A tangible computer-readable storage medium on which is encoded a computer program, the computer program comprising computer executable instructions configured for displaying a computer-generated geographic map on a video display by performing the steps of:
-
detecting an input signal for initiating a map zoning mode for an initial computer-generated geographic map, wherein the map zoning mode prevents zooming of all of the initial computer-generated geographic map; zooming multiple user-selected areas on the initial computer-generated geographic map, wherein said zooming generates a unique zoom window for each of the multiple user-selected areas, wherein each said unique zoom window displays and overlays an enlarged view of a corresponding user-selected area, from the multiple user-selected areas, over the initial computer-generated geographic map, wherein the multiple user-selected areas are each a different singular point on the initial computer-generated geographic map; displaying persistently and simultaneously all of the multiple zoom windows over the initial computer-generated geographic map; selecting each of the multiple zoom windows to selectively zoom to different zoom levels; detecting a distance between the user dragging a clicked mouse cursor from a user-selected singular point on the initial computer-generated geographic map to a final resting position of the mouse cursor, wherein the dragged distance automatically determines a size and zoom level of a zoom window; repositioning the zoom window when a pre-defined type of information displayed on the initial computer generated geographic map is detected to be obscured by at least one or more zoom windows; and
automatically repositioning the at least one or more zoom windows such that the pre-defined type of information displayed on the initial computer-generated geographic map is not obscured by any zoom windows; andaltering a physical appearance or a shape of a border of the zoom window in accordance with a unique condition of roads depicted within the zoom window. - View Dependent Claims (8)

9. A system comprising:
-
a specific processor; a display coupled to the specific processor; a tangible computer-readable storage medium on which are stored computer-executable instructions, wherein the computer-executable instructions, when executed, perform a computer-executed method comprising; detecting an input signal for initiating a map zoning mode for an initial computer-generated geographic map, wherein the map zoning mode prevents zooming of all of the initial computer-generated geographic map; zooming multiple user-selected areas on the initial computer-generated geographic map, wherein said zooming generates a unique zoom window for each of the multiple user-selected areas, wherein each said unique zoom window displays and overlays an enlarged view of a corresponding user-selected area, from the multiple user-selected areas, over the initial computer-generated geographic map wherein the multiple user-selected areas are each a different singular point on the initial computer-generated geographic map; displaying persistently and simultaneously all of the multiple zoom windows over the initial computer-generated geographic map; selecting each of the multiple zoom windows to selectively zoom to different zoom levels; detecting a distance between a user dragging a clicked mouse cursor from a user-selected singular point on the initial computer-generated geographic map to a final resting position of the mouse cursor, wherein the dragged distance automatically determines a size and zoom level of a zoom window; repositioning the zoom window when a pre-defined type of information displayed on the initial computer generated geographic map is detected to be obscured by at least one or more zoom windows; and
