quantizes TopoJSON
Synopsis
topoquantize [options] <n> [file]
Description
Quantizes the coordinates of the input TopoJSON topology and delta-encodes the topology's arcs. The quantization parameter n must be a positive integer greater than one, and determines the maximum expressible number of unique values per dimension in the resulting quantized coordinates; typically, a power of ten is chosen such as 1e4, 1e5 or 1e6. If the topology does not already have a bbox, one is computed and assigned. If the topology is already quantized, an error is thrown.
