THIS PAGE IS NO LONGER BEING UPDATED


Introduction

The purpose of this page is to provide a broad overview of the coverage of available imagery for Haiti. The aggregate boundary image found on the "Imagery and data sources" page provides an excellent overview of high resolution imagery available in the Port-au-Prince area and places west of the city. This page provides a coverage view across the entire country by Departments, but does not provide information on the resolution of the imagery.

Coverage table

The coverage table below addresses coverage at the Department level. A green gradient has been used to indicate %-coverage. The table at right shows the %-color translation. Data was captured by loading the Department boundary relation then calling the imagery via WMS; the resolution for the downloads varies from 6 km to 21 km and does not have an impact on the findings.

The %-coverage values are based on area measurement in JOSM and comparison to areas Department areas listed at wikipedia:Departments of Haiti#Demographics.

Rule of thumb: lighter shade = more coverage
