Image editing system for transmission network supervision

Claim 2

An image editing system for transmission network supervision comprising: means for creating station data as a data source for graphically displaying a plurality of stations within a specific area; first memory means for storing said station data; means for creating area data as a data source for graphically displaying a map of said specific area; means for creating, on the basis of said station data and said area data, map data for graphically displaying an area map, said area map including an image map of said specific area reduced to a desired scale, said plurality of stations superimposed on said image map and transmission routes connecting said plurality of stations; third memory means for storing said map data; and display means for graphically displaying said area map based on said map data.

Claim 3

An image editing system for transmission network supervision according to claim 1, wherein said area map includes names of said plurality of stations as well as names of said transmission routes.

Claim 4

An image editing system for transmission network supervision according to claim 2, wherein said station data are created on the basis of entries from input means, said entries comprising the names, management code numbers, longitude, latitude, and types of said plurality of stations within said specific area.

Claim 5

An image editing system for transmission network supervision according to claim 1, wherein said area data creating means creates said area data by first designating two reference points where appropriate on a map of said specific area; reading said map containing said two reference points through an image scanner attached to said system for conversion to image data; displaying said image map in accordance with said image data on said display means; and plotting said two reference points and an outer frame of said image map to obtain coordinate values of said image map.

Claim 6

An image editing system for transmission network supervision according to claim 4, wherein said image map displayed on said display means in accordance with said image data is arranged to appear within a window established on said display means.

Claim 7

An image editing system for transmission network supervision according to claim 4, wherein said reference points and said outer frame of said image map are plotted by clicking a mouse attached to said system.

Claim 8

An image editing system for transmission network supervision according to claim 5, wherein said map data creating means comprises: means for obtaining an x direction scale value of said image map by dividing the absolute difference between the x coordinate values of two display reference points on said image map by the absolute difference between the latitude values of said two reference points on the map of said specific area; means for obtaining a y direction scale value of said image map by dividing the absolute difference between the y coordinate values of said two display reference points by the absolute difference between the longitude values of said two reference points; means for obtaining an x coordinate value of a window reference point for providing screen display reference of said window by first dividing the x coordinate value of one of said two display reference points by said x direction scale value, and by subtracting the resulting quotient from the latitude value of one of said two reference points; means for obtaining a y coordinate value of said window reference point by first dividing the y coordinate value of said one display reference point by said y direction scale value, and by subtracting the resulting quotient from the longitude value of said one reference point; means for obtaining an x coordinate value of station display coordinates for displaying each of said plurality of stations on said image map displayed in said window, said x coordinate value being obtained by first subtracting the x coordinate value of said window reference point from the actual latitude value of each of said plurality of stations, and by multiplying the resulting difference by said x direction scale value; and means for obtaining a y coordinate value of station display coordinates for displaying each of said plurality of stations on said image map displayed in said window, said y coordinate value being obtained by first subtracting the y coordinate value of said window reference point from the actual longitude value of each of said plurality of stations, and by multiplying the resulting difference by said y direction scale value.
