A question came up on the US Census slack, leading to the recognition that the US Census Bureau API doesn't support queries for data for "all ZCTAs in a state". Nothing about the Census Bureau's definition of ZCTA requires that they be contained within a single state, which is probably why the API rejects the query with a message, error: unknown/unsupported geography heirarchy.

I've been looking for a general method to answer these kinds of questions for a long time. This Gist demonstrates a workable approach. It's based on data published by the Census LEHD LODES program, which provides, for every Census block in the US, a crosswalk indicating which geographies that block is in. (The set of geographies is limited but still very useful. See the technical doc PDF for more details.)

Making a big image zoomable

When you have a giant image and you want to make it easy to pan and zoom without downloading the whole 50MB image into someone's browser, a nice workaround is to cut that image into tiles at different zoom levels and view it as it were a map. An example where I've used this technique is The "Snowpiercer" Scenario.

One way to cut your big image into the requisite tiles is with gdal2tiles.py.

Alternatively, this Node script will do the cutting after you install node-canvas and mkdirp:

const fs = require("fs"),
