Description

Based on the scale data for #14, we should add a "metadata" module and some scale info when exporting, so on this line:

https://github.com/publiclab/infragram/blob/ba9f1a80686df826cce9ac426c821a999b00deda/index.html#L210

We also add something like:

,metadata{scale: '...'}

but we should think about how to express scale... is there some conventional formatting for scale data? Microns per pixel maybe?

Contributor guide

Research direction
Examine the image export function in index.html and research conventional formats for scale metadata (e.g., microns per pixel). Then implement a metadata module to include scale information.
