This document is a work in progress, and outlines my new workflow for generating contour lines.

Prep:

Load metadata for all available DEMs into into postgis. More on this later.

Prepare coastline data

Goal of this step is to get a series of polygons that can be used for intersection queries to determine if a contour is adjacent to the coastline.

Download OSM coastlines wget http://data.openstreetmapdata.com/coastlines-split-3857.zip
