22.5 Distribution and Deletion of Map Data; Data Saving
New or altered map data must be distributed to all radar indicators on which they are to be displayed. If
necessary, map data can also be deleted. It is recommended that the most recent set of data should be
saved on diskette.
☞ The most recent set of data should be available on all radar indicators (unless there are particular
reasons opposing this). One of the advantages of this is that it prevents loss of the most recent data,
which would occur if map data on an indicator containing old data were edited and if the map data
were then distributed.
File Structure of the Map Data
For the division of the map data into individual files, the earth’s surface is divided up into areas measuring
3° by 3°. All symbols and lines situated in such an area are grouped within a file.
☞ Lines going beyond one of these boundaries are cut at the boundary during the process of division
into files, and are joined together again when the files are called up for the purpose of display or
processing.
Furthermore, the earth's surface is divided up into areas measuring 15° by 15°. All map files belonging
to such an area are grouped within a catalog.
For the designation of the files and catalogs, the south-west corner of the area is used in all cases;
files have the file extension .D03, and catalogs have the extension .D15:
- The file S39E144.D03 contains all map data situated in the area bounded by the 39th and 36th
southern lines of latitude and by the 144th and 147th eastern lines of longitude.
- The catalog N15W075.D15 contains all map files of the data that are situated in the area bounded
by the 15th and 30th northern lines of latitude and by the 75th and 60th western lines of longitude.
☞ Just as a map file and the catalog are automatically created as soon as a symbol or line is edited
for the defined area, so are the file and (if applicable) the catalog deleted again as soon as there
are no longer any symbols and lines (or parts of lines) present in the area defined for the file and
catalog.
Transferring Map Files to Other Radar Indicators
1. Click on the index card Tools.
2. Click on Map Transfer, then on Transmit.
3. Click on the field under Destination. Mark the indicator to which the data are to be transferred, or
All indicators if the data are to be transferred to all installed radar indicators.
☞ The indicator designations listed here are identical to those entered in the header bar of the
System Maintenance Manager. If in doubt, switch on the System Maintenance Manager of the
destination unit, and have a look.
4. In the Files in Source list, mark the catalog or file that is to be transferred. If all files are to be trans-
ferred, mark the list entry at the top, designated by "/". By clicking on the Add >> button, put the
marked files and catalogs into the Files to Transfer list.
5. Repeat procedure 4 for other files/catalogs that are to be transferred.
☞ If too many files/catalogs have been entered by mistake, the content of the Files to Transfer
list can be deleted and procedure 4 can be repeated.
6. When all files/catalogs to be transferred have been entered, start the transfer by clicking on the
Transfer button.
