Size of Land

I have a plot of land and wish to put am island on top of it,a megga primm,how do i find out the size of the land,so know the right primm to rez,
Thank You.

World >> About Land gives you the area in sq. m., or you can simply measure it with a homemade meter stick. Be VERY careful putting a megaprim over your land. If it isn't positioned perfectly, it will lap over onto your neighbor's parcel and can cause you no end of trouble. Even if it doesn't, please think carefully about the visual effect of a large floating object. Be kind to your neighbors. They might be kind to you too.

thank you,at the moment it is water ,the prim will be the island

Are you aware of the fact that you can't walk on the surface of a sculpted prim? Presumably your idea is to use a sculpt map on that megaprim, to make it look like an island. But if you do that, it will have a bounding box that does not in any way match the visible surface. If all you want is an offshore island for visual effect, and never plan to set foot on it or to approach it very closely from below, that may be OK. But if you're hoping to add a cute prim island that you can use like normal terrain, on a parcel where the terraform limits won't allow you to raise the actual terrain above the water, you'll be very dissapointed.

Ah,Thank you Ceera
