Building county maps

1. Create a .geojson of your state counties in QGIS, in unprojected coordinates (raw lat-lng)
2. Convert to topojson, simplify and quantize to reduce file size:

geo2topo counties=mn_counties.geojson | toposimplify -S 0.007 --filter-all | topoquantize 1e3 > mn.json
geo2topo roads=mn_interstates.geojson | toposimplify -S 0.1 --filter-all | topoquantize 1e5 > mn_roads.json

geo2topo counties=ia_counties.geojson | toposimplify -S 0.007 --filter-all | topoquantize 1e3 > iowa.json

geo2topo counties=nh_counties.geojson | toposimplify -S 0.1 --filter-all | topoquantize 1e5 > nh.json
geo2topo roads=nh_interstates.geojson | toposimplify -S 0.1 --filter-all | topoquantize 1e5 > nh_roads.json

3. We're not currently doing this, but if you did want to reproject before using, tell the JS what projection values to use

geoproject 'd3.geoTransverseMercator().rotate([-134.3333333333333, 0]).center([0, 36]).translate([d.width/2,d.height/2]).fitSize([1500,1500],d)' < geojson_output.json > geojson_transversemercator.json

svelte app

This is a project template for Svelte apps. It lives at https://github.com/sveltejs/template-webpack.

To create a new project based on this template using degit:

npx degit sveltejs/template-webpack svelte-app
cd svelte-app

Note that you will need to have Node.js installed.

Get started

Install the dependencies...

cd svelte-app
npm install

...then start webpack:

npm run dev

Navigate to localhost:8080. You should see your app running. Edit a component file in src, save it, and the page should reload with your changes.

Deploying to the web

With now

Install now if you haven't already:

npm install -g now

Then, from within your project folder:

now

As an alternative, use the Now desktop client and simply drag the unzipped project folder to the taskbar icon.

With surge

Install surge if you haven't already:

npm install -g surge

Then, from within your project folder:

npm run build
surge public
