Finding Visible <i>k</i>NN Objects in the Presence of Obstacles within the User’s View Field <xref rid="fn1-ijgi-452448" ref-type="fn">†</xref>

In many spatial applications, users are only interested in data objects that are visible to them. Hence, finding visible data objects is an important operation in these real-world spatial applications. This study addressed a new type of spatial query, the View field-aware Visible <i>k</i>...
