S3 CloudFront Custom Domain CloudFormation example

	#
	# S3 bucket for a web files, with CloudFront and custom domain.
	#
	# The bucket is setup to be private, only accessible via CloudFront.
	# This uses a CloudFront OAI to provide access to the bucket, and also restricts
	# access to be SSL/HTTPS only.
	# The SSL cert was created manually, as it has to be created in us-east-1 for
	# use with CloudFront, and there is no way to specify a region in CloudFormation
	# when creating a cert.
	# Finally it does Route53 DNS setup for the subdomain pointed at/for use with

Script to import large raster data set in chunks via VRT files.

	#!/bin/bash
	#
	# Script to produce tiled raster import of a large data source, so that we can
	# import in chunks, and be able to handle failures. This takes the lat/long
	# mins and maxes for a rectangular area, and a VRT tile size and produces VRTs
	# for each tile. It also outputs a shell script to import those VRTs along with
	# outputting the last "rid" (raster ID in DB) after completing a tile, so that
	# if it fails, we know the items to delete (so we can restart the failed tile,
	# and not have duplicate records from what was partially imported).
