Detailed Description

Data structure holding a vector of data points. To reduce footprint, the data is sent as 8 bit values (octet). The data-structure holds an offset and a scaling factor, to restore the original data samples. e.g. double value = data * scale + offset The density parameter allows a layer to be of lower resolution than the map itself.
