Which of the following describes two spatial features that share at least one point but no interior points?

The description of two spatial features that share at least one point but no interior points accurately defines the concept of "touch." In geographic information systems (GIS), touching features are those that connect at their boundaries or vertices without overlapping any of their interior areas. This relationship can often be visualized in the context of overlapping roads or the edges of different land parcels that meet at a common point but do not extend into each other's area.

In contrast, the term "intersect" relates to spatial features that share some common area, including interior points, indicating a greater degree of overlap than mere touching. "Contain" describes a situation where one feature entirely encloses another, meaning there is a complete interior relationship rather than a mere boundary contact. "Overlay" generally refers to more complex spatial relationships where two features are combined or analyzed to produce new information, typically involving intersections of interiors as well.

Thus, "touch" is the term that best fits the description given in the question, emphasizing the specific nature of spatial relationship characterized only by shared boundary points without any interior connection.
