A minimal Sinatra app to run MapKnitter exports in the cloud, using the mapknitter-exporter gem.
- Gem: https://github.com/publiclab/mapknitter-exporter
- Rails app: https://github.com/publiclab/mapknitter
(note NOT https for now:) http://export.mapknitter.org/export?url=https://mapknitter.org/maps/pvdtest/warpables.json&scale=30
You can also run it as a POST or GET with a parameter called collection containing the JSON string.
var json = {[
{
"cm_per_pixel": 4.99408,
"nodes": [
{"lat":"-37.7664063648","lon":"144.9828654528"}, // id is also optional here
{"lat":"-37.7650239004","lon":"144.9831980467"},
{"lat":"-37.7652020107","lon":"144.9844533205"},
{"lat":"-37.7665844718","lon":"144.9841207266"}
],
"src":"https://s3.amazonaws.com/grassrootsmapping/warpables/306187/DJI_1207.JPG",
},
{ ... } // add as many images to the list as we want
]}
$.post("http://export.mapknitter.org/export", {
scale: 30,
collection: JSON.stringify(json) } )
.success(function(response) {
// response is the URL of a status.json file that will be continuously updated with the status of the export
});{
"status_url":"https://mapknitter-exports-warps.storage.googleapis.com/1557156175/status.json",
"status":"complete",
"tms":"public/tms/1557156175/",
"geotiff":"public/warps/1557156175/1557156175.tif",
"zip":"public/tms/1557156175.zip",

"user_id":null,

}The URLs can then be used like:
