OGC Health Domain Working Group Chair, Ajay K Gupta, discusses the merits of a Health Spatial Data Infrastructure (SDI) ahead of the publication of OGC's White Paper on the topic. 

For much time now, the OGC Health DWG has been working on a white paper to communicate to the health and geospatial communities the value that a Spatial Data Infrastructure (SDI) can bring to healthcare – and to encourage the development of such a resource for the global community - as SDI can be a platform to aid efforts to achieve healthcare’s twin goals of improving quality while reducing costs.

Misaligned maps? High-accuracy data must become time-dependent

Current web-mapping implementations are compromising datum modernisation programs by introducing metre-level misalignments of data. It is the start of a suite of high-accuracy and time-dependent mapping challenges the world is about to face.

While web-mapping has worked ‘well enough’ to date, it cannot support the high-accuracy requirements expected by modern users and data. It is hampered by the ambiguity inherent in the practical application of WGS84 as used by the Web Mercator projection, and lack of care with the recording and use of time metadata.

Open Portrayal Framework: Sharing Styles and Updating Tiles for a New Generation of Maps

The Open Portrayal Framework in OGC Testbed 15 is developing a conceptual model for styles together with a series of new APIs for styles, images, maps and tiles handling.
In the Open Portrayal Framework, a style is an encoding with essential information about itself, e.g. title, abstract description of the style, a thumbnail, and information about the data it can be applied to. These metadata elements allow users to share, discover, select, and apply a style. A style further contains a sequence of rules or instructions that define how mapping engines shall render vector or raster data or, in OGC speak, features and coverages.

During the recent TC Meeting in Leuven, Belgium, the Spatial Applications Division of the KU Leuven (SADL) organised the first Earth Observation Summit (EO-Summit) supported by EO4GEO and OGC. The summit aimed to help bridge the skills gap seen in the Earth Observation/Geographic Information (EO/GI) sector.

Trevor Taylor opens OGC's First Marine SummitDuring the recent OGC TC Meetings in Singapore, the OGC Marine Domain Working Group, in close cooperation with the International Hydrographic Organisation (IHO) and Singapore’s Maritime and Ports Authority of Singapore (MPA), organised the first OGC Marine Summit.
The purpose of the Summit was to: promote the value of interoperability and discoverability of marine spatial data (and MSDI); create awareness of data standards and applications applicable to marine data acquisition and use; explore the uses, challenges, and cutting-edge applications for geospatial data in the marine domain; and further the development of marine standards in both hydrographic and broader, non-hydrographic fields (e.g. ecology, energy, tourism, geology).

GeoPackage is often seen as a container that stores geospatial information, but at its core, GeoPackage is simply a SQLite database. This opens up a realm of possibilities to interact with and exploit its contents. We can incorporate advanced analysis into our data, or augment with other data types like basemaps, elevation, and other forms of media, all within the same package.

Usefully, GeoPackage can even accomplish offline Network Routing. Here's how.

In September 2018, the OGC/WMO Hydrology Domain Working Group (HDWG) held its ninth annual workshop marking ten years of successful collaboration between the World Meteorological Organisation (WMO) and OGC in hydrology and informatics. The working group has generated interoperability experiments, engineering reports, discussion papers, best practice documents, and four approved OGC standards - part of the WaterML2 suite. 

OGC @ ApacheCon 2018

This year marks the 20th anniversary of ApacheCon. For the last several years, we’ve had a strong representation at Apache from projects in the Geospatial sciences space. Just as collaboration is so important in the sciences, it is at Apache, and Apache seems to be a great fit for Geospatial projects, giving an open, collaborative way to work on the code that matters to Geospatial scientists, across the boundaries of corporations or research organizations. Through these projects, the ASF has forged a great relationship with OGC, and for the last couple of years we’ve had Geospatial tracks at ApacheCons in Vancouver, Seville, and Miami. This year at ApacheCon North America, in Montreal, we once again are excited to be featuring a track of Geospatial-focused talks, in cooperation with OGC.
