STATEMENT OF WORK

TITLE: Open Geospatial Consortium Testbed Sponsorship Requisition Number: NB671000-18-00998 LAB REQUESTING SERVICE: National Institute of Standards and Technology (NIST) Communications Technology Laboratory (CTL), Public Safety Communications Research (PSCR)

I. BACKGROUND INFORMATION

The PSCR program conducts research, development, testing, and evaluation to foster nationwide interoperability and advanced communications and operations technology for the nation’s public safety community. PSCR currently has an active research program studying various aspects of location-based services, including indoor mapping, localization, and navigation. PSCR has sponsored both internal and external research in these areas. In addition, NIST, with funding from PSCR, recently joined the Open Geospatial Consortium (OGC) at the Associate membership level to facilitate collaboration with its OGC network of over five-hundred companies, universities, and government agencies.

OGC organizes annual testbed activities as part of their Innovation Program to provide a venue for creating and advancing solutions to complex geospatial challenges through open frameworks and standards. Testbeds provide a unique platform where sponsors can outsource the rapid generation of prototypes and test environments with leading organizations in their field. Testbeds can result in more than just prototypes. Depending on the level of success and need, new updated standards are often produced, in addition to guides, overviews, and best practices for solving leading edge geospatial problems.

II. SCOPE OF WORK

PSCR seeks activities in OGC Testbed 14 to address key problem statements related to indoor mapping and navigation for first responders.

First responders typically survey high-risk facilities in their jurisdiction as part of a preplanning process.

While the outputs from preplanning are often in report form, first responders may annotate available floor plans (e.g. from CAD models) or generate their own hand-drawn maps during the process.

Preplanning is potentially time-consuming and inefficient, especially considering the information and level of detail that should or could be captured, the lack of automation, and potential difficulty identifying notable changes to facilities and infrastructure during resurveying.

PSCR has identified mobile 3D light detection and ranging (LiDAR) as a potentially transformational technology for first responders. Leveraging 3D LiDAR and coupled with advanced software processing, first responders could very efficiently capture 3D point clouds and a wealth of other information, both observed and derived, while walking through buildings as part of their routine preplanning operations.

The use of 3D LiDAR has many potential upsides beyond just creating point clouds for visualization and mapping, e.g., use in localization, object classification, integration with virtual/augmented reality solutions, etc. Though not widely used currently for surveying, especially outside the architectural, engineering, and construction (AEC) community, it is expected that investments by the automotive and unmanned aerial systems industries will drive the costs of 3D LiDAR down dramatically over the next five years so that it will become a cost-effective tool for public safety, building owners/managers, and various service industries.

To accelerate research and development for this public safety driven use-case, PSCR would like to focus on the following demonstration activities for Testbed 14:

1. Create and convert 3D indoor LiDAR point cloud models to functional building and navigation models.

2. Store and serve point cloud, building, and navigation models for visualization and navigation.

3. Derive dynamic turn-by-turn indoor navigation instructions based on the navigation model.

4. View and annotate point cloud and building models, along with navigation routes and instructions into, through, and out of buildings.

III. SPECIFICATIONS

Not applicable.

IV. PERIOD OF PERFORMANCE

The period of performance for Testbed 14 is one year.

V. PLACE OF PERFORMANCE

Work will be executed at OGC and performer facilities.

VI. DELIVERABLES

The following list identifies deliverables to support the activities above. OGC will ensure all software and systems developed and or enhanced within Testbed 14 remain available and operational to the sponsor for a period of six (6) months following the completion of the testbed.

NIST001: Point Cloud Model – Using a 3D LiDAR survey instrument of sufficiently high quality, the participant will create a 3D point cloud model of the indoor and outdoor of a test building. The test building should be sufficiently large and complex to adequately test the dependent deliverables (e.g.

airport, large apartment complex, manufacturing facility, etc.). The model should have a global accuracy of 5 cm and be delivered in LAS file format1.

NIST002: Public Safety Features CityGML ADE – The participant will define a Public Safety Features CityGML application domain extension (ADE) based on the reference preplan symbology created by the National Alliance for Public Safety GIS (NAPSG)2. The ADE will be documented as a CityGML Schema and described in an OGC Engineering Report (ER). The schema and ER will be proposed as a change request to the CityGML SWG.

NIST003: Building Modeler – The participant will create a building modeler application that can convert point cloud models (such as those generated by NIST001) into semantic 3D building models compliant with the most recent or stable version of CityGML. Models generated by this component will be notated with Public Safety Features from the CityGML ADE (NIST002). The building modeler may be developed as a web processing service (WPS) compliant with the OpenGIS WPS Interface Standard, though this is not a strict requirement.

NIST004: Navigation Modeler – The participant will create a navigation modeler application that can convert output from the building modeler (NIST003) to IndoorGML usable for indoor navigation. The building modeler may be developed as a web processing service (WPS) compliant with the OpenGIS WPS Interface Standard, though this is not a strict requirement.

NIST005: Building Model Repository – The participant will create a building model repository that will store and serve point cloud, building, and navigation models (NIST001/3/4). The repository will expose a model catalog and provide authenticated access. The repository will be interoperable with application clients leveraging the OGC Web Feature Service (WFS) Interface Standard and OGC 3D Portrayal Service

(3DPS) Standard.

NIST006: Indoor Navigation Service – The participant will create an indoor navigation service that can derive ‘turn-by-turn’ instructions between any two points in a building, including exits, based on models created by the navigation modeler (NIST004). The service will be able to integrate a variety of navigation algorithms, not necessarily developed in this testbed, optimized for specific criteria (e.g.

routes optimized based on time, distance, or risk) requested by the preplanning tool (NIST007). While not a requirement for this testbed, the solution should be developed keeping in mind the dynamic, real-time requirements that navigating during a real public safety response will impose upon the service.

The service will use the OGC WFS Interface Standard. WFS will also be leveraged to request scenes from the model repository that can be provided via 3DPS format.

NIST007: Preplanning Tool – The participant will create a visualization client application for users to request and view point cloud (NIST001) and building models (NIST003) from the model repository (NIST005), as well navigation instructions and routes from the indoor navigation service (NIST006). The client will have a graphical user interface that enables public safety personnel to view and annotate models captured during preplanning. The client will seamlessly transition between 2D and 3D views and will allow users to visualize hypothetical routes into, through, and out of buildings along with the appropriate metrics (e.g. estimated time, distance, risk, etc.) based on additional input parameters considered by the navigation service. The client will use the OGC WFS Interface Standard and OGC 3DPS to request and receive models, scenes, and services.

NIST008: PSCR Presentation – Selected participants in the PSCR sponsored portion of OGC Testbed 14 will be required to participate in the PSCR Public Safety Broadband Stakeholder Meetings June 5-8, 2018 in San Diego, CA. Because the PSCR stakeholder meeting will be during the design phase of the Testbed, presentations will cover progress to date.

NIST009: Engineering Report (ER) – This ER will describe architecture developed in Testbed 14 that meets the PSCR requirements.

NIST010: Demonstration Videos – Videos that capture demonstrations of the individual deliverables and the end-to-end workflow developed for first responder building preplanning operations.
