Welcome to the HealthDWG web


The OGC Health Domain Working Group enables OGC to identify and work with a representative group of market participants in the identification and prioritization of use cases, business and technical requirements that will provide the most significant value, or mitigate the most significant risks in this arena. Through efforts to identify requirements, gaps in standards and opportunities for demonstration, an OGC Health Domain Working Group (OGC Health DWG) contributes to development of open mapping standards in support of health marketplace requirements. Through bringing together geospatial vendors and end-users, the OGC Health DWG helps to cultivate technical solutions which support interoperable concepts, data definitions, formats and services for publishing, search, and exchange of geospatial information. More information on the OGC portal.

This wiki provides information about the current and planned work of the OGC Health DWG.


The OGC Health DWG arranges regular teleconferences to advance activities which support members and address geospatial data and web service interoperability needs, as stated in our Charter. The OGC Health DWG workplan is developed with input of the working group members. This may include, but is not limited to, convening the working group around specific issues, identifying opportunities for interoperability demonstration, and strengthening market awareness and adoption of OGC standards in service of health-related needs.


Details for OGC Health DWG teleconferences and meetings will be posted here, and in the OGC Member Portal.

The OGC Health Domain Working Group held a teleconference February 10th, 2014, to help prioritize needs and activities of the Health DWG in 2014.

The OGC Health DWG met during the OGC-TC, March 27th, 2014. A report of the meeting was prepared for the OGC-TC plenary and distributed via the Health DWG listserve. After introductions and update from Chair, there was an introduction to WMO High Impact Weather Research Program ( WMO_Research_Programme.pdf) and invitation for members of the Health DWG to participate. At the meeting, a motion was successful, to motion the OGC TC to approve the nomination of a co-chair for the Health DWG. Participants discussed at a high-level some of the possible driving scenarios / areas of mutual need (interoperability) that could become the focus of our activities this year, or for future requests for sponsors and interoperability projects/demonstrations. Action items were recorded, including the need to advance cross-SDO activities (e.g. with HL7) and collaboration with other key programs/organizations, and populate this listserve with 'wish-list' items (by Health DWG members).

Highlights from the meeting: The OGC Health Domain Working Group met for 55 minutes, during the OGC-TC in Geneva, June 10, 2014. There was agreement to advance an HL7 – OGC Statement of Understanding, and encouragement for members to identify and move forward on discrete areas of work. Guest presenters provided insight on potential alignment of OGC Health DWG activities with health domain requirements for standardization and interoperability. This included WHO eHealth and European Innovation Partnership initiatives. There was discussion and interest in further details by members. Co-Chairs noted the need to advance liaison efforts with each and to focus on standardization relevant at global or multinational-level. This would be added to the previously identified links to GEOSS Health SBA, INSPIRE Human Health and Safety, and WMO Hi-Weather Research Program ( WMO_Research_Programme.pdf). A brief introduction was made on the purpose of Engineering Documents/Reports and our work toward introducing documents for consideration of the DWG / OGC TC, inviting input on focal areas. Possible topics for such documents include: HL7, eHealth, SDMX-HD and integration with OGC standards, Mobile Health and ‘Extreme Weather and Health’. We did not schedule enough time to allow the presentation/discussion of cutting edge examples of OGC implementation for health applications, or gaps for future research. Co-chairs noted the need for more time in future Health DWG sessions, both for discussion and to steer proposed documents. There are now 66 subscribers to the Health DWG List-Serve. Articles and Wiki Content continue to be welcomed from DWG participants.

Action Items:
  1. Advance HL7 – OGC Statement of Understanding. Discrete areas of work to be identified.
  2. Co-Chairs will invite input on how OGC Standards can serve health application areas identified, and where work is needed; establish a liaison with WHO on health information systems.
  3. Co-Chairs will invite input on focal points for Documents; to inform potential Interoperability Experiments or demonstration projects.
  4. Update Wiki with meeting summary and PPTs, new content.
  5. Advance activities in alignment with our Charter goals / Statements of Need; Recognition of implementations (e.g. for eHealth) is through national / sub-national entities.
  6. Schedule more time for OGC Health DWG sessions
The OGC Health DWG held a 2 hour session on February 17, 2015. There were two presentations, linked below, and one participant poll.
  1. Presentation on UNCAP: "Ubiquitous iNteroperable Care for Ageing People" UNCAP will bring to the development of an open, scalable and privacy-savvy ICT infrastructure designed to help aging people (including those with cognitive impairments) live independently, with dignity, maintaining and improving their lifestyle. In particular, UNCAP will leverage on an interoperable ecosystem of biosensors and indoor & outdoor localisation solutions, to deliver an infrastructure capable to continuously monitor –in a non-invasive way- the users and assist them when required. Wide support for well-established interoperable industry standards will allow creating a scalable ICT ecosystem leveraging on both different biosensing solutions and on existing home-automation solutions, interoperable with existing Personal Health Record (PHR) systems. This presentation helped inform OGC Health DWG participants, helped maximize benefit with respect to implementation of OGC standards, and engaged those who are interested in the project, at the very early stage. This presentation was given by Giuseppe Conti, of Trilogis (project coordinator). Some key points include: overview of project goals, scenarios / use cases / piloting in various countries; addressing challenges on privacy, scalability, interoperability, automation; data transfer between OGC OWS and HL7, KNX (for building automation), ETSI, and InterRAI for clinical assessment; potential for best practices for O&M profile for health care application; space-time analysis (real-time); project will provide end-use applications for patients and care givers; IndoorGML will be most important, also important is OGC SWE – though more feedback is needed; other OGC standards may also be used (e.g. WMS), but not the focus of the project.
  2. Presentation by Klaus-Peter Schipper: European Innovation Partnership on Active and Healthy Ageing, spatial working group, identifying synergies, needs and opportunities for standardization. This presentation was given by Klaus-Peter Schipper of GeoHIT – Geographic Health Information Technology, Università della Svizzera italiana, Switzerland. Some key points include: much is developed in siloes / fragmented – need to decrease inequalities, identify synergies / overcome siloes, promote multi-vendor/multi-national implementations. Effort is now being made to ‘map’ the ‘mappers’ / to identify EU projects that are implementing OGC standards-based geospatial services/using geospatial data; Need to assimilate taxonomies, measurements/indicators; Need improved transferability across nations; EC can fund portion of this. Need compliance and validation platform. Need cooperation between EIP and OGC to undertake analysis of potential use-case applications with OGC standards, to facilitate adoption as part of national e-health systems across EU and abroad.
  3. Co-chairs compiled a short document listing key topics (e.g. requirements for geospatial data and web service interoperability, or health benefit areas) identified by OGC Health DWG participants. Participants helped to refine / identify focus areas and potential contributors to documentation, throughout 2015.
  4. Co-chairs highlighted mutual areas of interest. Comments were captured as follows:

    • “Best practices for implementing existing OGC standards”… comments: inside EU, NIH, and other nationally funded projects
    • “Environment – Health Applications” comments: further liaison with GEOSS Health and Environment Community of Practice, Identify best practices and useage of geodata, OGC Health DWG could look at requirements in Geo H&E and link to standards.
    • “Health Info Privacy” comments: Members may contribute to documentation (e.g. from UNCAP project)
    • “Data Schemas” comments: the word schema is open to interpretation. We need to focus on taxonomies… indicators/measurements for health care applications, e.g. in e-health, including units, calibration, not just storing of results. We need to consider: relational, conceptual, physical (how measurement is calculated and stored), semantic, etc. schemas; need to be able to go from one definition to another (across cultures / countries); consider different measures, definitions, not only for health data, but for human activities (such as running, walking, eating etc.)
    • “Time Series modeling, analysis, visualization” comments: also consider multi-dimensional spatial data/time series modeling, analysis, visualization, as a potential paper topic. There are differences in data requirements and data models used, for individuals vs for population health. We need to consider time series data obtained through multiple standards / data sources.
    • “OGC compliance for web and mobile applications….” comments: possible under WHO, or EC, with OGC, to set up a compliance platform (for interfaces complying to OGC specifications). Currently compliance is more oriented to machine-to-machine interfaces (agnostic to end-use)… We need an ‘interface’ / compliance platform to make sure implementations are user friendly to health care community. Taking new standard implementations and transferring to other sites/users is also important.
    • Other comment: we must consider geometry / topology of the human body (paper topic?) – including potential interconnections/functions of systems in the body (in time and space).

The OGC Health DWG held a 2 hour meeting on March 10, 2015, during the OGC TC. Presentations are linked, key points made are provided in-line.
  1. Presentationby Kyoung-Sook Kim, AIST: a project has just been started to extend our current system (environmental monitoring system based on OGC standards such as SOS, CWS, WCS, etc.) for health application. In early stages of the project, we are now trying to verify a good example of use case to involve human health problems against the level of radiation. Also, the project looks at some other standard documents such as SDMX-HD and HL-7 in order to figure out how to combine them with/into OGC standards. This presentation was given by Kyoung-Sook Kim, researcher with Data Science Research Group, Information Technology Research Institute (ITRI), National Institute of Advanced Industrial Science and Technology (AIST), Japan. Some key points include: a Fukushima radiation monitoring database project RALFIE has recently started, focused on exposure estimation for individuals; finding hot spots for administrative decision making; record of a person’s LifeLog; Life pattern mining. Problem of low quality crowd sourcing. Usage of SensorThings API and moving features; wrap raw radiation data with OGC web services (SOS, WFS, WCS, WMS); combination of radiation data with weather data for correlation analysis; Measurement of radiation: level, type and exposure are important - the level can vary day by day. AIST has developed a new compact radiation sensor. The radiation sensor is connected to a smart phone.Exposure estimate as cloud service. Issue: time series track and personal life logging - People not usually willing to share whole LifeLogs, but want experts to interpret data and compare with other cases. Issue of making summary (protecting privacy).HL7 for exchanging health data; Relevant issue: standards in health domain, incl. HDMX-SD; W3C for statistics. Standards gaps: lifelog data, summary data; needs vocabulary. Eurostat uses HDMX.
  2. Presentation by Giuseppe Conti, Trilogis (lead): UNCAP "Ubiquitous iNteroperable Care for Ageing People" ( UNCAP_presentation.pdf ) an innovation project funded under Horizon 2020 (the research and innovation framework of the European Commission) - UNCAP will bring to the development of an open, scalable and privacy-savvy ICT infrastructure designed to help aging people (including those with cognitive impairments) live independently, with dignity, maintaining and improving their lifestyle. In particular, UNCAP will leverage on an interoperable ecosystem of biosensors and indoor & outdoor localisation solutions, to deliver an infrastructure capable to continuously monitor –in a non-invasive way- the users and assist them when required. Wide support for well-established interoperable industry standards will allow creating a scalable ICT ecosystem leveraging on both different biosensing solutions and on existing home-automation solutions, interoperable with existing Personal Health Record (PHR) systems. Some key points include: this is a Horizon 2020 project on cognitive impairments; Aims to keep people at home as long as possible. Key concept: indoor location. UNCAP Box as product; KNX as interface to home automation. Standards used: OGC, HL7, ETSI (for M2M communications), interRAI (to assess cognitive abilities). Aim: to define a profile of O&M. “Position” and location is important. Position seems to be understood as a context or situation like “waking up very late”. The project uses floor sensors to detect falls. Will do benchmarking to compare before and after system put into use. Use cases and requirements have just been finished. All deliverables will be open (documents and software). To do: system architecture (HW and SW technology), O&M profile for personal health and care.
  3. Presentation by Dr. Peter Baumann: Raster Data Processing for Geo and Life Sciences: Commonalities ( Health-DWG_Geo+LifeSciRasters.pdf ): Multidimensional arrays (aka raster data) form a fundamental data category in science and engineering, such as in medical imaging and satellite image services. To achieve versatile Web services on such data - in particular: on "Big Data", multi-dimensional array query languages have been devised. The OGC Web Coverage Processing Service (WCPS) operates on spatio-temporal regular and irregular grids represented as coverages. ISO SQL is being extended with array querying and modelling in a domain neutral way, but based on the same underlying concepts. We presented the state of standards and technology in massive multi-dimensional array services and point out commonalities and differences. Peter Baumann is editor of the OGC WCPS standard, co-editor of the ISO SQL Array extension, and pioneer of the research field of Array Databases. Some key points include: OpenGL has support for multidimensional data rasters - Example for human brain mapping and masking with brain components,3D barin tomographies, Gene expression analysis, map to rgb image. ISO 9075 Part 15 SQL/MDA. Select clause, for post processing and searching. Queries can ask for data and meta-data at same time. Processing on server side. Agile array analytics used by ESA under Copernicus Big Data challenge 2014- master programme. Adaptive tiling; Query re-writing to optimize performance; Just in time compilation for GPU; Distribution and parallelization over clouds; Benchmarking planned in EarthServer2 to compare rasmadan against Hadoop; earthserver.eu.
  4. Participants provided an ad-hoc summary of activities in the European Innovation Platform, Active and Healthy Aging. Societal changes: More people are going to be tech savvy; The urban fabric is changing; also urban planning; A “silver economy” is developing; People are having children at a later age; ICT seems to be a key enabler for active aging; Need to reach out to European Connected Health Alliance http://www.echalliance.com/; CEN TC431 on social alarms; AAL (Ambient Assisted Living) is looking for OGC to be a frame organization for standards. What standards are they looking for? A participants is working on a H2020 project with the task of monitoring all projects in the health area; Standards range from medical to technical (e.g. smart flooring); Also significant are geo standards and common formats.
  5. Co-chairs invited OGC Health DWG participants to contribute to key topics (e.g. requirements for geospatial data and web service interoperability, or health benefit areas) identified by OGC Health DWG participants. The table ( Topic_List_with_Action_Responsibilities.docx ) shows the poll results. The respective person /organization will prepare a one page abstract on the topic by May 31, 2015 as a basis for the development of Discussion Papers (or possibly Best Practices) to be submitted for consideration by OGC-TC. The abstract should describe the scope of the planned paper and as far as known the status of and requirements for supporting standards (OGC and non-OGC). This topic list will continue to be updated with participant input throughout 2015.
Topic List for Abstract development: Topic_List_with_Action_Responsibilities.docx This topic list will continue to be updated with participant input throughout 2015.
