Introduction

This page is a manual proof-of-concept related to maximizing the return-on-investment for making satellite imagery available for use in Humanitarian OpenStreetMap Team-coordinated efforts. The problem that this approach addresses is the difficulty in collating lists of places which are covered by available high-resolution imagery in a way that facilitates division-of-labor and elevation of minimum map tracing results for areas which are not designated as top-priority by relief agencies.

This approach capitalizes on the emergence of gridded .osm files for several imagery coverage areas in Haiti. These .osm files have been provided by User:Crschmidt in late January (see addition diff).

Most elements of the work below could be conducted by automated scripts; this manual activity aims to determine utility and requirement leading up to an automated method.
