@_slack_hotosm_U03K8PR2NKC:matrix.orgNarayan Thapa Yes please host it in aerial map 15:37:27
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister I will see what I can do - can you email me a request with some details - are you working with an NGO or local group? Goals of project, who it helps, etc? Does the project have a web site or anything? Does not need to be formal, just so I have all the details in one place - marc.pfister@maxar.com 15:41:11
@_slack_hotosm_U03K8PR2NKC:matrix.orgNarayan Thapa Yeah sure 15:42:40
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister Is this for Langtang Earthquake in 2022? 17:54:50
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister There is a big pile of older imagery for Nepal here: https://qoomon.github.io/aws-s3-bucket-browser/index.html?bucket=https://dg-opendata.s3.amazonaws.com/#events/nepal-earthquake/post-event/ 17:55:13
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister I don't know where it is yet 17:55:24
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister also maybe here https://qoomon.github.io/aws-s3-bucket-browser/index.html?bucket=https://dg-opendata.s3.amazonaws.com/#events/monsoon-india-nepal-bangladesh/ 17:58:43
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister nepal-earthquake is from 2015 https://www.maxar.com/open-data/nepal-earthquake 18:14:35
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister https://discover.maxar.com/dda809a8-a02c-11ee-aa51-8dc6d1b6c37e is available there and over your valley 18:15:26

@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister Some recent Nepal imagery related to the 2015 quake has just been added to Maxar Open Data https://radiantearth.github.io/stac-browser/#/external/maxar-opendata.s3.amazonaws.com/events/Nepal-Earthquake-Apr-2015/collection.json 20:00:54
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister Batuhan Kavlak the above image is ready for OAM ingest at https://maxar-opendata.s3.amazonaws.com/events/Nepal-Earthquake-Apr-2015/ard/collects/10500100371C7600.tif 22:27:56

@_slack_hotosm_U02R7FJD23G:matrix.orgBatuhan Kavlak niceee! I can login. Do you also add a merged tif now? 06:33:58
@_slack_hotosm_U02R7FJD23G:matrix.orgBatuhan Kavlak Is temporal extent correct in this context? 🤔 06:40:32
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister yes because it's a pushbroom sensor, it took approximately 2 seconds to scan north 14:59:46
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister We have a setup for merging now but it's not automatic yet 15:01:36
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister Usually we average the timestamp to the center but since we processed the strip into tiles each tile computed its own time stamp and then that gets interpreted as a range in the STAC collection. For the purpose of the merged tiff you can use the midpoint of that range. 15:09:03
@_slack_hotosm_U02R7FJD23G:matrix.orgBatuhan Kavlak aah, I’m confused with the title Nepal Earthquake Apr 2015. Was it related to the request referencing that event? I missed the conversation, I guess. I’m uploading with this info 15:25:02
@_slack_hotosm_U068ACWRKP1:matrix.orgMarc Pfister Yes, this was the request for newer imagery in the thread above this one, so it's after the 2015 event date. We haven't moved any of the actual 2015 imagery over from the old bucket so the only thing in the new bucket is this 2023 image. 15:30:02
@_slack_hotosm_U02R7FJD23G:matrix.orgBatuhan Kavlak uploading, thanks a lot for merging the TIF, it’s really useful 15:33:18
