IGSN list for a geospatial polygon

• The end point is https://app.geosamples.org/samples/polygon
• Usage:https://app.geosamples.org/samples/polygon/[lon1 lat1, lon2 lat2, lon3 lat3, lon4 lat4, lon1,lat1].
  • [lon1 lat1, lon2 lat2, lon3 lat3, lon4 lat4, lon1 lat1] are points of a concave polygon. Please note that the last point is the same as the first point.
• The service will retrieve all IGSNs whose geo-coordinates are located within the user defined polygon. It only accepts GET requests from the client program. It does not require login and password and supports pagination. If hide_private flag is set to 1, it will not return IGSNs whose sample metadata are not public accessible. It supports spatial reference systems transformation.

Request Headers

• Accept: application/xml, application/json, text/xml, text/json

  Request Body

• [lon1 lat1, lon2 lat2, lon3 lat3, lon4 lat4, lon1 lat1]: longitudes, latitudes for a polygon. Please pay attention to the last coordinate which is the same as the first one to form an enclosed polygon.
• limit={limit}: maximum IGSN number for each page. If it is not specified, it will default to 100.
• page_no={page_no}: page number. If it is not specified, it will default to 1.
• hide_private={1 or 0 or none}: default to 0. If 1, it will not return IGSNs whose sample metadata are not public accessible.

Response Body

HTTP status codes:

• 400 Bad Request - User specified polygon is not valid.
• 404 Not Found - No IGSNs associated with the given polygon
• 200 Successful. It will return a list of IGSN(s) as following.

Output format when request is successful ( status code = 200 ) XML format:
