推荐答案

假设您正在使用向量数据....
用最小的距离缓冲单击的宗地，使其与邻居重叠(通常为1个单位)，并寻找与其他宗地的交点.

Hi,

Assuming you are using a vector data....
Make a buffer of the clicked parcel with minimal distance to overlap with neighbors (usually 1 unit) and look for intersection with other parcels.

您正在处理哪种宗地?如果它们的形状/大小一致，那么您应该能够在用于支持GIS功能(甚至在SQL Server中)的任何库/框架中进行一些简单的计算.

我假设您没有将关系存储在某个地方，因此您可能不得不漫步"周边并寻找唯一性.

What kind of parcels are you working with? If they are uniform in shape/size, you should be able to do some simple calculations in whatever library/framework you''re using to support the GIS functions (even in SQL server).

I''m assuming you don''t have the relationships stored somewhere, so you''ll likely have to ''walk'' the perimeter and look for uniques.
