The Global Environment Monitoring System (GEMS) is a multi-faceted water science center created by the United Nations Environment Programme. GEMS' goals are to improve global water quality monitoring and assessment abilities and to determine the status and trends of regional and global water quality. GEMStat is a global water quality database designed to provide access to surface and groundwater quality data and statistics collected by GEMS.
GEMStat provides two online services for accessing its data: the Web Feature Service and the Web Map Service. The Web Feature Service returns information on GEMS stations and the measurements they've taken. The Web Map Service provides maps of GEMS station locations. Both of these services are accessible programmatically using either SOAP or REST calls.
The following is a list of historical changes that were made to this asset. Typically,
once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change.
As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset,
we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all
activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb.
If you spot an error in our data and believe that a record needs to be updated in some way,
