TileMantle

A tool to warm up your tile server cache. Give it a URL template, geometry, and list of zoom levels and it will request tiles incrementally to warm it up.

$ npm install tilemantle -g

$ tilemantle -h

Usage: tilemantle <url> [<url> ...] [options]

Options:
  --version          Display version number
  -h, --help         Display usage information
  -l, --list         Don't perform any requests, just list all tile URLs
  -z, --zoom         Zoom levels (comma separated or range)
  -e, --extent       Extent of region in the form of: nw_lat,nw_lon,se_lat,se_lon
  -p, --point        Center of region (use in conjunction with -b)
  -b, --buffer       Buffer point/geometry by an amount. Affix units at end: mi,km
  -d, --delay        Delay between requests. Affix units at end: ms,s
  -m, --method       HTTP method to use to fetch tiles
  -r, --retries      Number of retries
  -H, --header       Set request header                                        
  -c, --concurrency  Number of tiles to request simultaneously

Usage

# use a point with a 12mi radius 
$ tilemantle http://myhost.com/{z}/{x}/{y}.png --point=44.523333,-109.057222 --buffer=12mi -z 10-14

# use an extent (nw,se)
$ tilemantle http://myhost.com/{z}/{x}/{y}.png --extent=44.523333,-109.057222,41.145556,-104.801944 -z 10-14

# use a geojson geometry as bounds
$ cat region.geojson | tilemantle http://myhost.com/{z}/{x}/{y}.png -z 10-14

# use a geojson geometry as bounds + buffer by distance
$ cat region.geojson | tilemantle http://myhost.com/{z}/{x}/{y}.png --buffer=20mi -z 10-14
