Hi @yputhealy,

Hi @yputhealy,

Looks like you can do something like this and just add a Streamlit button:

from owslib.csw import CatalogueServiceWeb
import urllib

def getLinkByIDCWS(url, id, user, pwd):
    csw = CatalogueServiceWeb(url, username=user, password=pwd)

    csw.getrecordbyid(id=[id])
    csw.records[id].references

    link = csw.records[id].references[2]['url']

    return link

def downloadImage(url, fileName):
    urllib.request.urlretrieve(url, fileName)

url = "http://localhost:8080/geoserver/csw?service=CSW&version=2.0.2&request=GetRecords&typeNames=gmd:MD_Metadata&resultType=results&elementSetName=full&outputSchema=http://www.isotc211.org/2005/gmd"
record = "nurc:Arc_Sample"
name = "<user>"
pwd = "<pwd>"

link = getLinkByIDCWS(url, record, name, pwd)
print(link)

downloadImage(link, "test.arc")

Hi @yputhealy,

I don’t have an example on-hand that does exactly what you’re looking for, but it seems pretty doable for you to implement from the above example. Feel free to reach out to the community if you get stuck

Best,

Caroline
