The German Gymnastic Federation is very satisfied with the actual valid International Specification for Orienteering Maps (ISOM). Of course, there are some special Middle-European features which might be presented with special symbols. But as the number of symbols should not be increased, national interests should keep back. Especially vegetation objects must not be overemphasised. Nevertheless there are some suggestions to increase line width and screens for a better legibility:
101, 103 | Contours and form lines to be increased from 0,125 to 0,14. |
115, 204, 205, 303 | the symbol "V" to be increased |
306, 307 | crossable small watercourse and minor water channel to be increased from 0,125 to 0,18 |
406 | Forest, slow running; screen to be increased from 20% to 30% |
408 | forest, difficult to run; screen to be increased from 50% to 60% |
509 | narrow ride to be increased from 0,125 to 0,15 |
