sourcefootprint table #15

Open sppigot opened 5 years ago

sppigot commented 5 years ago

This is keyed to both the datasets (via datasetsourcefootprint) and projects (via projectid). A number of questions here:

How to resolve the shape (integer) to the geometry of a polygon (for inclusion in the metadata record) and the thumbnail/graphic overview of the source. Should this info be held in the source record (seems logical).
Whether and then where to hold the area_sqkm field
imagedate field = resource creation date in metadata record
Any need to hold relationships between sources and the mosaics that they are a part of (via mosaicfootprintid)

Export IWS footprint source feature class to GML - provide to Simon
Look into the current pdf tool that generates the thumbnail and if it can be used separately in Geonetwork - provide Simon with a directory of the thumbnails and a method to link to the correct metadata record.
Drop the area_sqkm field
Image date field will be the resource capture date
there's a relationship between sources and projects but not for mosaics - still to be discussed within the CIP team.

A question about the image creation date. It only exists in the source footprint table. Do mosaics need to capture this info? If they did, which date would they use or would they use an extent derived from the imagedate? Also the project has a year of acquisition time range which would probably be the maximum of all these imagedates? Do we need to hold imagedate then?

Good question. comment from Darren; Most mosaics will have the earliest date of capture as part of the mosaic name captured in the image name field, however the last capture date is only recorded in the source footprints. Is there a capture start date and capture end date for each dataset that gets manually entered into Geonetwork as part of the metadata entry workflow? I have a vague recollection of this being part of the dataset metadata record entry in the early mock-up Simon showed Michael and I, but I don’t know if this has persisted in later revisions.
