pzsvc preview generator external service

Purpose of pzsvc-preview-generator is to showcase piazza's core capabilites. This app exposes rest endpoint, takes a post request containing payload of required metadata. Points to the s3 location, downloads, crops the raster file, and uploads the cropped raster back up to s3 bucket.

Usage:

Post a request with a payload. url: https://pz-svcs-prevgen.stage.geointservices.io/crop

Local: http://localhost:8086/crop

Use sample working payload:

{
    "source": {
        "domain": "s3.amazonaws.com",
        "bucketName": "pz-svcs-prevgen",
        "fileName": "NASA-GDEM-10km-colorized.tif"
    },
    "function": "crop",
    "bounds": {
        "minx": -140.00,
        "miny": 10.00,
        "maxx": -60.00,
        "maxy": 70.00
    }
}

Service will download the file from "pz-svcs-prevgen" s3 bucket and crop it with given bounding box info. The cropped result tif will be uploaded back up to s3 bucket "pz-svcs-prevgen-output": https://console.aws.amazon.com/s3/home?region=us-east-1#&bucket=pz-svcs-prevgen-output&prefix=

If all goes well, the resulting received payload will be of DataResource type:

{
  "dataType": {
    "type": "raster",
    "location": {
      "type": "s3",
      "bucketName": "pz-svcs-prevgen",

      "domainName": "s3.amazonaws.com"
    },
    "mimeType": "image/tiff"
  },

    "description": "Service that takes payload containing S3 location and bounding box for some raster file, downloads, crops and uploads the crop back up to s3.",

  }
