template <class Allocator = allocator<bool>> class vector<bool, Allocator> RemarksThis class template specialization behaves like vector, except for the differences explained in this article.Operations that deal with the bool type correspond to values in the container storage. allocator_traits::construc...
The testing of whether the characteristic vectors lies within the target area is made for each image point on the object. The point with the characteristic vector lying within the target area is correctly considered, and the point with the vector lying outside the target area is incorrectly ...
The vector tiles should appear with custom colors for residential, commercial, government, industrial, and institutional land parcels. All remaining parcels should be displayed in gray.
