痛点：土地挂牌常声称“邻近/背靠公共土地”，但实际可能隔路或相距很远，买家需手动逐块核查县GIS边界，效率极低。
目标用户：购买林地/狩猎地/离网宅基地的买家，以及服务这类客户的房地产经纪、狩猎和户外人群。
证据：Listings kept saying things like "adjacent to state land" or "backs to state forest," but when I checked county GIS maps, many didn't touch public land at all. Some were across a road, some were a quarter mile away. I eventually found a property that borders state game lands but only after checking boundary lines by hand, one parcel at a time. ... I've shared it with a few homesteading and off-grid communities and the response was very encouraging
变现：免费基础查询+单次地块报告付费；面向房产经纪/狩猎向导/土地投资者的订阅；按线索或API调用收费；聚合公共土地接壤地块的邮件提醒。
MVP：输入地址或地图选点后，调用县地块边界与USGS PAD-US公共土地数据，计算是否真正接壤、共享边界英尺数，并用卫星图高亮接壤边；支持保存/分享报告，先覆盖用户最集中的几个州。
竞品：LandGate、AcreValue、OnX Hunt、Regrid、County GIS 官方查询工具
摘要：独立设计师用低成本工具和地产数据集做出 unfenced.land，将县地块边界与 USGS 公共土地数据比对，判断是否真正接壤并测量共享边界英尺数。它源于在 Poconos 找狩猎/露营地时，挂牌常声称邻近州地但实际可能隔路或差四分之一英里的痛点。已分享给 homesteading 和 off-grid 社区并获鼓励，但未披露收入或明确付费意愿。
