bounding box and point coordinates limiation in PDC #11

Open bhaleka opened 5 years ago

bhaleka commented 5 years ago

PDC metadata currently only accepts a bounding box of coordinates for the data’s location but there is a limitation to this. For example, this metadata record www.polardata.ca/pdcsearch/PDCSearchDOI.jsp?doi_id=13077, provided by the researcher actually consists of only 5 monitoring stations from the United States, one of the stations is located in Alaska. However, since we are limited to bounding boxes in PDC, WAMEDEX will highlight all of Canada as being studied by the researcher. This is not an accurate representation of the study area. This is not ideal for many of the data we are collecting at UW. We need to have options to include, point coordinates, shapefile and bounding boxes within the PDC system.

I couldn't find a publicly accessible document of ISO 19115, but https://geo-ide.noaa.gov/wiki/index.php?title=File:EX_Extent.png suggests there is a way to express Polygons in the standard. Wamedex could easily display polygons (just as Cuizinart does)

Do these systems use PostGIS?

Here is the link to one of the standards that PDC follows https://www.fgdc.gov/standards/projects/metadata/base-metadata/v2_0698.pdf

Working to get the ISO standard

not sure about PostGIS. I use a webform for inputting metadata on PDC so I don't much about their system.
