Detailed Description

Grid map managing multiple overlaying maps holding float values. Data structure implemented as two-dimensional circular buffer so map can be moved efficiently.

Data is defined with string keys. Examples are:

"elevation"
"variance"
"color"
"quality"
"surface_normal_x", "surface_normal_y", "surface_normal_z" etc.
