Pyramid

Generate tiles pyramid for an image.

alt text

Installation

This assumes that Node.js has already been installed.

npm update @geopan.io/pyramid -g

Usage

pyramid <image>

Tradeoffs

  • The image tiling happens in parallel for a given level. This could be improved to both speed up the process as well as limiting the risk for spike in CPU consumption.
  • There is risk that for really big images, like orthophoto, the memory suffers with this approach and I would concider using node stream interface instead.
  • I would add unit testing. Currently a single one to illustrate how to deal with Jest.

Help
