What you’re seeing: your LINZ parcel boundary on satellite imagery, priced by property area. InSAR reads buildings and hard surfaces best — it’s less reliable on bush, water and very fast movement. See “Where LandSure works best” below.

Please read before you buy. LandSure is not a geotechnical engineer, and this report is not analysis, certification or a professional opinion. Think of it as a canary in the coal mine - a satellite data report that flags where the ground may be moving. It is meant to be used alongside your local geotechnical engineer, who knows your area and the differences in the land. InSAR does not work equally well in all land types, so please check that this product is right for you before purchasing.
