Summit OH/JS-070 coordinates are put inside restricted military area.
I was looking at map and the elevations and I was thinking is it OK to activate the summit from from west to the restricted area at coordinates 61.430523, 23.758750 - which is outside the military area but on the same hill? I think the elevation is the same there?
There aren’t too many summits here in southern Finland and this is in my QTH city, so it would be tempting to activate it.
The activation area is defined by the contour 25 metres below the summit that encloses the summit. This summit’s at 194 metres, so the 169 metre contour is the one within which you’d have to get. The OpenTopo map doesn’t have a 169 metre contour line, but it does have a 170 metre one which is close enough to make very little difference. If you find the 170 metre contour on the OpenTopo map you’ll see that it is completely within the red shaded military danger zone, so that summit’s not one you can activate unless you can somehow get permission from the base authorities…
@M0LEP Thanks for the detailed answer!
The activation zone is bounded by the land surface 25m lower than the summit. The representation of this on a map is only as good as the source data for the map, obviously. I would suggest that the MML national mapping for OH is the map to use rather than OpenTopoMap.
In fact MML have free 2m DEM files to download. Here I have made my own contour from these LIDAR-derived terrain data, set 25m below the highest point. As you can see the shape departs significantly from that of the close contours in the SAR-derived OpenTopoMap (I see my contour crossing 4 of the OTM 10-m contours!).
In any case I’m afraid it looks like you’re out of luck. Perhaps you can ask for permission from the military?
Yup, here is MML map:
For me it looks like that the second “peak” is at the same height or even higher?
The perimeter of the AZ at the 25m-down contour is where the AZ finishes. Anywhere outside of this perimeter is invalid, even if the ground rises up again to be within 25m of the summit elevation.
I think you miscounted the contours. Both peaks to the west are about 27m lower than the high point, confirmed by the LIDAR DEM.
One of the club stations on the OI-award might have some information.
Summits on private land are common in North America, I think.

Ask if the Base has a radio club or if there are any Hams that work there. Maybe you can go onto the base as a guest and activate the summit.
Before I forget, any outdoor enthusiast visiting Finland might be interested in recreational orienteering events. The maps are very detailed and you can find your way with the map and a compass.
And of course the special orienteering for radio amateurs.

Hello,
One person just asked if this is possible to activate.
OH3CUF contacted to military personel in this area but access was denied. So i suggest that this should be delete from the map.

No. As explained many times and explained in SOTA rules, summits are included in the program if they meet the requirements for their association. Just because they are listed does not mean anyone can activate them. Reasons why you cannot activate include military ground, religious grounds, private grounds, wildlife preserve, contaminated ground, radio quiet zone. There are many reasons why you cannot activate them. But that is today. Tomorrow the access rules may change and activation is possible, So the summits stay listed.
You can add an access restriction tag to the summit on sotadata site, so others will know when they look it up.
An example from here
W9/IL-009, Gold Hill - 215m, 1 point, Still No Access(submitted by N4DCW on May 7, 2022).
Those visiting common law world might want to AI “trespassing”.
