I fly in an area where there are many windmills. They are generally clustered in individual parks. When I get an obstacle warning from SD, it warns me about every single windmill. This can be annyoing if I get 10 individual warnings about obstacles which are only 100 m or so apart.

Suggestion: issue only a‌‌ single warning if obstacles are spaced very closely together. The warning message could alert the pilot that it is about multiple obstacles.
