Abstract

A method for charting onto a newly produced map mains network data from an old, existing map. It comprises the following steps. In a first memory part is stored the measured data for a new map. In a second memory part is stored the data of the old map including the data relating to mains networks. From the memory parts the new and the old map are read and displayed on a display. Reference points of the old map are moved until they coincide with the appropriate reference points of the new map. Finally, The network reference points moved with the reference points of the old map are interpolated so that the network data is included in the new map.

Claims

1. Method for charting onto a new map, mains networks from an old, existing map, comprising the steps of:

storing in a first memory part measured first data for the new map;

storing in a second memory part second data of the old map including data relating to mains networks included in the old map;

reading from the memory parts the first and second data and displaying the first and second data on a display means;

moving reference points of the old map until these coincide with reference points of the new map; and

interpolating mains network reference points moved with the reference points of the old map so that mains network data is included in the new map, said interpolating step including consulting a code which indicates how said mains reference points of the old map are to be linked and made to coincide with said mains network data included in the new map.

2. Method as claimed in claim 1, including manually verifying interpolation of the mains network reference points.

3. System for charting onto a new map, mains network data from an old, existing map, comprising:

a first memory part for storing measured first data for a new map;

a second memory part for storing second data of the old map including data relating to mains networks included in the old map;

data entry means for entering map data into at least one of the first and second memory parts;

a display means for displaying thereon the new map, the old map and mains network data;

a processor including means for moving mains network reference points of the old map into the first memory part, said first and second memory parts, said data entry means and said display means being connected to communicate with said processor; and

a control program loaded into the processor means for interpolating the moved mains network reference points to coincide with reference points of the new map so that the first data is included in the new map, and further means in said control program for consulting a code which indicates how said old mains network data is to be linked and made to coincide with said reference points of said new map.

4. The system of claim 3, wherein said data entry means comprises a movable member.

5. The system of claim 4, wherein said display means includes means for simultaneously displaying thereon said old map and said new map.

6. The system of claim 5, wherein said display means is effective for displaying said old map and new map in different colors.

7. The system of claim 3, wherein said data entry means comprises a digitalizing table.
