My usual question: will there be image metadata available for these layers, preferably in a machine readable form that allows editors for a spatially selective suggestion of the best available imagery? > The good news: imagery will be more recent and more frequently > updated with our latest Maxar mosaic content.

A quick look at some critical areas shows that while coverage is similar or better than with the old layers there is a significant number of places where either the Standard and Premium layers now feature the same image or where a well mapping suitable image (at high latitudes usually: near snow and ice minimum) is being replaced by a less mapping suitable image: https://www.openstreetmap.org/#map=13/73.4207/54.9987 https://www.openstreetmap.org/#map=13/75.8010/-83.9056 There seem to be some rendering artefacts at the lower zoom levels: https://earthwatch.digitalglobe.com/earthservice/tmsaccess/tms/1.0.0/DigitalGlobe:ImageryTileService@EPSG:3857@jpg/11/1940/304.jpg?connectId=d9c5e3ef-6300-4cec-9562-c1f27da6b2d9 https://earthwatch.digitalglobe.com/earthservice/tmsaccess/tms/1.0.0/DigitalGlobe:ImageryTileService@EPSG:3857@jpg/13/2834/2333.jpg?connectId=d9c5e3ef-6300-4cec-9562-c1f27da6b2d9 Examples of useful improvements: https://www.openstreetmap.org/#map=15/-57.1171/-26.8197 https://www.openstreetmap.org/#map=14/75.8120/137.6692 https://www.openstreetmap.org/#map=14/81.5993/-16.6763 https://www.openstreetmap.org/#map=13/-77.9505/166.6831 -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
