1. Introduction

The Open Geospatial Consortium (OGC) is releasing this Call for Participation (CFP) to solicit proposals for the OGC Testbed-17. The Testbed-17 initiative will explore eleven tasks, including Application Programming Interface (API) development, enhanced GeoJSON, Aviation, CITE, Geo Data Cubes, Sensor Integration, Moving Features from motion imagery, Security, Federated Cloud Analytics, COG & Zarr, as well as Model Driven Standards.

Testbed 17

1.1. Background

OGC testbeds are an annual research and development initiative that explores geospatial technology from various angles. They take the OGC Baseline into account, and at the same time explore selected aspects with a fresh pair of eyes. Testbeds integrate requirements and ideas from a group of sponsors, which allows leveraging symbiotic effects and makes the overall initiative more attractive to both participants and sponsoring organizations.

1.2. OGC Innovation Program Initiative

This initiative is being conducted under the OGC Innovation Program. This program provides a collaborative agile process for solving geospatial challenges. Organizations (sponsors and technology implementers) come together to solve problems, produce prototypes, develop demonstrations, provide best practices, and advance the future of standards. Since 1999 more than 100 initiatives have taken place.

1.3. Benefits of Participation

This initiative provides an outstanding opportunity to engage with the latest research on geospatial system design, concept development, and rapid prototyping. The initiative provides a business opportunity for stakeholders to mutually define, refine, and evolve service interfaces and protocols in the context of hands-on experience and feedback. The outcomes are expected to shape the future of geospatial software development and data publication. The Sponsors are supporting this vision with cost-sharing funds to partially offset the costs associated with development, engineering, and demonstration of these outcomes. This offers selected Participants a unique opportunity to recoup a portion of their initiative expenses.

2. Technical Architecture

This section provides the technical architecture and identifies all requirements and corresponding work items. It references the OGC standards baseline, i.e. the complete set of member approved Abstract Specifications, Standards including Profiles and Extensions, and Community Standards where necessary. Further information on the OGC standards baseline can be found online.

Please note that some documents referenced below may not have been released to the public yet. These reports require a login to the OGC portal. If you don’t have a login, please contact OGC using the Additional Message textbox in the OGC Innovation Program Contact Form.

Testbed Threads

The Testbed is organized in a number of tasks. For organizational purposes, these tasks are further organized in threads. Each thread combines a number of tasks that usually share architectural or thematic aspects. Threads allow us to keep related work items closely together.

The threads include the following tasks

2.1. Sensor Integration

Sensor systems are built using many different standards, formats, and protocols. This is a significant barrier to sensor integration. Yet there are good reasons why this should be so. Sensors must be deployed where they will best measure a physical phenomenon that imposes non-negotiable constraints on their size, weight, power, and communications capabilities. These constraints limit the options available to the designer. They must select the best option that will work within their technical constraints.
