Different types of survey points
How to make a difference between different types of survey points? International nautical maps use 4 different symbols depending if the survey point is a triangulation point, observation point, fixed point, or a benchmark. (see INT 1 B20 - B23) --Skippern 09:03, 3 May 2011 (BST)
- I see you added these to the page as type=*. That is recommended to be avoided (see Key:type) as it can be confusing or difficult to understand. For this case, it would be better to use either survey_point=* or survey_point:type=* --Neuhausr (talk) 12:57, 8 July 2015 (UTC)
Some hunting cabins have been mapped as observation points. I suppose this is incorrect ? What is an observation point ?
