Re: [OSM-talk] Skybox for good imagery test
This is not what Skybox has stated publicly (later), seehttps://lists.openstreetmap.org/pipermail/legal-talk/2014-November/008053.html https://lists.openstreetmap.org/pipermail/legal-talk/2014-November/008053.html This may or may not be in conflict with what Mikel wrote, but in any case there is more than enough fuzziness to sit quiet at this point in time. Simon Thanks Simon, I hadn't seen that. Will speak with Mikel. Rob ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Skybox for good imagery test
I had a closer look at the imagery provided under the Skybox for good grant. https://mapsengine.google.com/00979750194450688595-08887688179650036554-4/mapview/?authuser=0 Opening the GeoTiff directly in JOSM using the ImportImage plugin works but JOSM gets quite slow due to the large file size. So I decided to tile the image for easier viewing. Alignment of the imagery looks fine. There is some distortion of the imgery compared to the existing OSM data. Without GPS tracks its difficult to say what is more accurate. See for yourself around this area: https://www.openstreetmap.org/#map=16/29.7137/91.7383 Data is here: http://downloads.osm-tools.org/sb4g/ Browse either using a web browser or by adding a TMS layer to JOSM tms[18]:http://downloads.osm-tools.org/sb4g/{zoom}/{x}/{-y}.png I created the tiles from a 1.4 GB tif, resulting directory was 875MB. Creation took 16 minutes. gdal2tiles.py -z 0-18 s02_20141006T032553Z-geo.tif sb4g Keep in mind that the above imagery was no HOT activation. So using it for OSM is not allowed. I assume someone at HOT will replicate the tiling once imagery is available and provide a TMS server.

Re: [OSM-talk] Skybox for good imagery test
Just to pick up on your point about HOT. Google has confirmed that Imagery released under Skybox for Good can be digitized into OSM under OSM's license. This applies to all imagery whether the imagery was captured following a request from HOT or any other organisation. Currently we have the following statement: https://lists.openstreetmap.org/pipermail/talk/2014-October/071318.html Whilst a more formal written text is sitting with Mike Collinson and we hope to have him and LWG ok it soon. Best, Rob p.s. Any comments on alignment very welcome especially if evidenced with GPS traces. :-D ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
