DESCRIPTION:# Context and purpose\nOGC standards shape a backbone within th
 e OSGeo community in defining a pathway to software implementation toward 
 the standardization of geospatial information and related services ensurin
 g interoperability between FOSS4G software. Since 2016\, the OGC has initi
 ated the specification of a new generation of standards based on the OpenA
 PI so as to facilitate integration in modern web applications and systems.
 \n\nUnderpinning the OGC API roadmap\, the development of all these standa
 rds represents a significant amount of activities carried out by various O
 GC working groups\, testbeds and pilots from the OGC Innovation Program. S
 ome standards have been approved\, many are still under development and it
  is therefore not always easy to follow the progress. Indeed\, while some 
 geodata infrastructures involving national entities are already deploying 
 this new generation (e.g. Canada MSC GeoMet)\, some initiatives run a phas
 e of experimentation (e.g. Geonovum Testbed Platform for the Dutch geoport
 al).\n\nFrom a practical perspective\, how can organizations and instituti
 ons anticipate to leverage this new generation of standards to deploy a ge
 ospatial data infrastructure? This issue is what this article is about\, i
 ntroducing a project that seeks to address it by running an OGC API testbe
 d platform with a special focus to the Swiss context. This project is embe
 dded in the Resources for the NSDI Program (related to the Swiss Geoinform
 ation Strategy) with the purpose to contribute to the upcoming revision of
  e-government standards regarding geoinformation (e.g. eCH-0056 Geoservice
 s application profile). The project is about a study jointly carried out b
 y swisstopo and complementary academic partners (HEIG-VD\, SUPSI\, UNIGE).
 \n\n# Approach\nAs a result of the above mentioned complexity and overlapp
 ing of existing standards\, the project team has applied a benchmark study
  approach\, where different standards are tested in experimental cases and
  evaluated in comparison of other existing solutions. The outcomes include
  both quantitative and qualitative results that will be condensed in pract
 ical recommendations for implementation and adoption of the OGC API family
 .\n\nThis research aims at evaluating a selection of different OGC specifi
 cations as well as different server and client implementations in order to
  define e-government recommendations to promote collaboration between auth
 orities\, companies and individuals.\n\nThe selected mainstream topic for 
 the experimental cases is about climate change. While not yet connected in
  a complex pilot study\, each case represents one of the required componen
 ts: from sensing (remote/in-situ) to data visualization and exploration\, 
 through data offering and elaboration. The study is organized in three par
 ts:\n\n* The hydro-meteorological monitoring network of the Canton Ticino\
 , which is currently managed using the SOS standard\, has been selected as
  representative of a practical implementation of basic data required for t
 he climate change impact assessment pipeline. The network\, which has a 40
  years long time-series\, is currently composed of 60 stations and 140 sen
 sors observing precipitation\, air temperature and humidity\, water temper
 ature\, river height. Collected information is operationally used by the l
 ocal administration to design and actuate water resources protection and a
 llocation to guarantee a sustainable management of the resource and the na
 tural environment while protecting from the impacts of extreme events like
  floods and droughts. The Sensor Things API operational applicability is e
 valuated by testing this standard to fulfil all the major in place daily p
 ractical operations like for example data quality management\, data sharin
 g with third parties\, data collection from vendor specific sensors and da
 ta analyses and visualization.\n\n* Switzerland was the second country in 
 the World after Australia to have an operational satellite Earth Observati
 ons (EO) Data Cube. The Swiss Data Cube (SDC) is a tera-scale analytical c
 loud-computing platform allowing users the access\, analysis and visualize
  up to 38 years (1984-2022) of consistent calibrated and spatially co-regi
 stered optical and radar Analysis Ready Data. The SDC leverages the inform
 ation power of Big Earth Data for monitoring the environment by minimizing
  time and knowledge required for analysing large volumes of raster data. T
 he derived analytical products provide an effective means to build sociall
 y robust\, replicable\, and reusable knowledge\, to generate ready-to-use 
 products supporting evidence-based decisions. Currently\, all the data pro
 ducts and their related description (i.e. metadata) are accessible through
  “traditional” OGC services such as WMS\, WCS\, CSW. For example\, the
  Normalized Difference Water Index (NDWI) time-series can be used to estim
 ate and monitor the evolution of vegetation water content over the entire 
 country. The aim of the experimental case will be to use a set of new OGC 
 APIs implemented on top of the Swiss Data Cube to track the evolution of N
 DWI. To reach this objective we will implement the OGC API Coverages\, Pro
 cesses\, EDR\, Records\, STAC APIs to access NDWI raster data time-series 
 and compute zonal statistics using different administrative units/levels (
 e.g. national\, canton).\n\n* Given past activities of the team project re
 lated to portrayal interoperability with OGC standards like WMS\, WMTS\, S
 LD/SE\, this part aims to challenge a set of specifications of the OGC API
 \, especially Features\, Tiles\, Maps\, Styles and to provide insights abo
 ut OGC SymCore. At one side\, the experimental case will consider outputs 
 from running Geoclimate\, an open source geospatial toolbox to compute a s
 et of urban climate related parameters describing a given area of study us
 ing OpenStreetMap data as a base. The intent is to make these indicators d
 iscoverable and to serve them as data and maps through the OGC API. At the
  other side\, the aim is to address national needs for geodata visualizati
 on using the Minimum Geodata Models (MGDM) in conjunction with their styli
 ng models\, testing how the symbol description may be encoded in a standar
 d way with modern formats and techniques to build styles and symbology (i.
 e. from SLD/SE to GeoCSS with or without cascading\, etc).\n\nFor all thes
 e experimental cases\, FOSS4G are deployed\, especially at the server leve
 l with FROST\, pygeoapi\, Geoserver\, QGIS Server. The results are useful 
 for developers\, government agencies and organizations who want to impleme
 nt and use the new family of OGC standards.
