Brings tech from graphics research, movie industry, and
game industry to 3D Tiles defines a spatial data structure and
a set of tile formats designed for 3D, and optimized for
streaming and rendering
• Built on on the glTF™ from Khronos® Group
• 3D buildings, photogrammetry, BIM/CAD models
• Point Clouds – for massive point clouds, per-point
attributes.
• Composite – for aggregation of tiles of different formats.

Evolution of OGC Web Services
• Modernized service/resource/REST architecture
• OpenAPI specification and toolkits
• OGC/W3C “Spatial Data on the Web” Best Practices
• Focus on developer experience
• Modularizes into OWS “building blocks” for reuse
in any microservices APIs
Open process: all in public GitHub repo, early
implementations, in-depth validation, slow release

OGC Vector Tiles Pilot Objective
• Leverages commercial
innovation in Vector Tiles
to rapidly extend existing
OGC services & encodings
• Objective: Develop VT
extensions for OGC WFS
3.0, WMTS and GPKG in
collaboration with industry
partners, deliver in weeks
not years.
• Extensions will serve as
basis for National System
for Geospatial Intelligence
(NSG) Profiles. VTP Daraa, Syria test area. Test data is NGA TDS OSM from NSG
Open Map Enclave. Topographic, Satellite Overlay and Night Styles.

 Successful TIEs performed between client and server
providers during the pilot:
 An abstract test suite was also developed during the pilot.

Vector Tiles Pilot: WMTS results
 No changes necessary to WMTS to support vector tiles;
vector tiles (MVT or JVT) are simply advertised as another
available output format
 For tiles not adhering to v2.1 of the MVT specification, it is tricky to
determine whether a given polygon contour is outer or inner; v2.1
includes specific order rules for this)
 Issues related to clipping of polygons at tile edges; two
approaches used; add buffer to tile and clip at buffer edge OR clip
at tile edge and mark artificial segments; no mechanism to
negotiate which approach to use and no mechanism in Geo
 Vector tiles should have an ‘id’ for features that matches the
feature ID before the vector data was tiled
 Tiling schemes should offer additional flexibility such as the ability
to describe tile matrices of different widths at different latitudes
(e.g. CDB grid, GNOSIS grid)

Vector Tiles Pilot: GeoPackage results
• Extends the Tiles option
• Adds five extensions
– Vector Tiles (base extension) adds two metadata tables
to support vector tiles
– Mapbox Vector Tiles allows MVT tiles (not a standard)
– GeoJSON Vector Tiles allows GeoJSON tiles
– Vector Tiles Attributes allows attributes from vector tiles
to be stored in attributes tables for easier querying,
leveraging the Related Tables Extension

Interoperable framework to integrate IoT sensors for public safety
• To advance Smart Cities in
– Public safety, policing, urban resilience
– Open architecture for interoperable IoT
• Current situation
– Lack of consensus on architecture
results in divergent, contradictory
activities;
– Insufficient interoperability and
scalability
