# Adding a New Map
To add a new map, follow the instructions [in this commit
message](https://github.com/tdooner/brigade-maps/commit/15b485c1d8c4f2e8ff4fc1542961ab991bf60cbd)
# Uploading to Cloudinary
```
node bin/upload.js > cloudinary_images.csv
# Recommended: use `jq` to count number of tiles to be uploaded, `pv` to show upload progress:
# node bin/upload.js | pv -ls ${ jq ‘. | length’ < build/tiles.json} > cloudinary_images.csv
```
Copy `cloudinary_images.csv` to a Rails server, and then update the Districts
with the appropriate images from a Rails console:
```
open('cloudinary_images.csv') do |csv|
csv.readline # advance past headers
csv.each_line do |row|
ocdid, level, version, public_id = row.strip.split(',')
District.
joins(:civic_division).
where(level: level).
where(civic_divisions: { ocd_id: ocdid }).
update_all(image: "v#{version}/#{public_id}.png")
end
end
```
