Intro

EcoHack sponsor Digital Globe has generously made their archive available to EcoHack attendees. If you want to browse their imagery via a map interface, use the MyDigitalGlobe viewer. You can download full-resolution scenes, but it can take a long time for a scene to be processed, and you'll use a lot of bandwidth. Please be reasonable. The REST APIs are very responsive and use less bandwidth, so if you know what you want, just use those.

Please do not use the REST APIs to scrape DG's archive. They will shut off access if they detect scraping.

REST APIs

WMS
Basic endpoint: https://services.digitalglobe.com/mapservice/wmsaccess?connectid=1c800d25-9c83-43a9-af2f-4d6dfc816d0f
Working queries:
recent Bayview, San Francisco
less recent Bayview, San Francisco
N.B.: bounding box specified as xmin,ymin,xmax,ymax

WMTS
Basic endpoint: https://services.digitalglobe.com/earthservice/wmtsaccess?connectid=1c800d25-9c83-43a9-af2f-4d6dfc816d0f

WFS
Basic endpoint: https://services.digitalglobe.com/catalogservice/wfsaccess?connectid=1c800d25-9c83-43a9-af2f-4d6dfc816d0f
Working query: Bayview, San Francisco (xml)
N.B.: bounding box defined as ymin,xmin,ymax,xmax, unless you specify an input CRS in the query, in which case bbox is specified like for WMS

WCS
Basic endpoint: https://services.digitalglobe.com/deliveryservice/wcsaccess?connectid=1c800d25-9c83-43a9-af2f-4d6dfc816d0f

Notes/gotchas

Bounding boxes - see notes above for WMS and WFS services.
WMS resolution - You must specify the size of the requested image (e.g. 1000 x 1000 pixels), along with the bounding box. This determines the effective resolution of the image you get. If your bounding box is square but the pixel dimensions define a rectangle, the image will be distorted to match the pixel dimensions requested.
WMS image size - Don’t request anything larger than 6000 pixels on either x or y axis - you’ll get an error.
