Method of handling context during scaling with a display
First Claim
1. A method for displaying a zooming operation on a display screen of a computing platform, the method comprising:
- obtaining a collection of data for displaying images showing features;
using said data to display on the display screen a first image showing features at a first scale with a first level of detail and then to display on the display screen a second image showing the same features at a second scale with a second level of detail, wherein the second scale is different from the first scale; and
between the displaying of the first image and the displaying of the second image, displaying on the display screen an intermediate image that combines two component images showing at least some of the same features,wherein said intermediate image is a temporary transitional image that illustrates a relationship between the first image and the second image,wherein the two component images in the intermediate image are at a same scale, andwherein the two component images in the intermediate image are registered so that the sane features represented in the two component images coincide.

Abstract
A method for displaying a zooming operation on a display screen of a computing platform. The method includes retrieving data from a geographic data storage system, possibly located on another system, displaying a starting image that shows geographic features at a first scale with a first level of detail and then displaying an ending image that shows the same geographic features at a second scale with a second level of detail. Between the displaying of the starting image and the displaying of the ending image, at least one intermediate image is displayed. The intermediate image combines two component images of at least some of the same geographic features shown in the starting or ending image. The two component images in the intermediate image are at the same scale and are registered with respect to each other so that the same geographic features represented in the two component images coincide. One of the two component images in the intermediate image includes at least a portion of the starting image and is formed using data from a first layer of a geographic database. The other of the two component images in the intermediate image is formed using data from a second layer of the geographic database.

12. A method of providing context while zooming an image on a computing platform the method comprising:
-
obtaining data to represent features at a first scale in a first image; displaying said first image on a display screen of the computing platform; using data to represent at least some of the features at a second scale in a second image, wherein the second scale is different from the first scale; if a request forte second scale with the zooming operation has been submitted on the computing platform, displaying said second image on the display screen after displaying said first image; using data to represent at least some of the features in a transitional image separate from the first image and the second image; displaying said transitional image on the display screen after displaying said first image and before displaying the second image. - View Dependent Claims (13, 14)

15. A method of presenting an image on a display screen of a client computing platform, comprising:
-
sending a request from the client computing platform to a server for image data;
on the client computing platform, receiving image data from the server;using the image data to present on the display screen of the client computing platform a first image that represents features in a first scale; initiating a zooming operation on the client computing platform; and presenting a transitional image on the display screen of the client computing platform, wherein the transitional image includes at least a portion of the first image and also includes a second image of the same features shown in the portion of the first image, wherein the same features shown by the first image and the second image in the transitional image coincide. - View Dependent Claims (16, 17)

18. A method of zooming an image on a computer display comprising:
-
obtaining image data; using said image data for displaying representations of features on a display screen at a first scale with a first level of detail; displaying representations of at least some of the same features on the display screen at a second scale with a second level of detail, wherein the second scale is different from the first scale and the second level of detail is different from the first level of detail; and displaying a transitional image after the displaying of the representations of the features at the first scale and before the displaying of at least some of the same features at the second scale, wherein the transitional image is separate from said representation at the first scale and said representation at the second scale, wherein the transitional image overlays representations of at least some of the features at two different levels of detail, wherein the two different levels of detail include one of; the first level of detail and the second level of detail, the first level of detail and a level of detail between-the first level of detail and the second level of detail, and the second level of detail and a level of detail between the first level of detail and the second level of detail. - View Dependent Claims (19)
