1 OGC GEOPACKAGE AND HOW OPEN SOURCE IS CHANGING THE WAY GOVERNMENTS THINK ABOUT STANDARDS Nathan Frantz Geospatial Research Lab Dr. Ben Tuttle National Geospatial-Intelligence Agency FOSS4G 2015

2 Geospatial Research Laboratory (GRL) Who is GRL? 1 of 7 labs that make up the Engineer Research and Development Center (ERDC) US Army Corps of Engineers GRL focuses technical efforts in the following mission areas: Terrain Analysis for Signal and Sensor Phenomenology Geospatial Temporal Information Structure and Framework GeoEnabled Mission Command Geospatial Reasoning Imagery and GeoData Sciences

3 Why GeoPackage Effective, large-scale collaboration in military, homeland security, and disaster management relies upon the sharing of geospatial information significantly constrained by limited or non-existent bandwidth An explosion of map applications for mobile handheld devices has resulted in a variety of incompatible data formats and interfaces. No existing standard addressed the provisioning of all types of geospatial data as well as be platform independent Data Interoperability Data Duplication

4 GeoPackage: Raster Maps, Images and Feature Data in One File Imagery Low High Resolution Feature Data Raster Maps: Small Large Scale Tile Pyramids 24 zoom levels

5 GeoPackage: A brief history Foundations established and tested prior to 2012 MBTiles SQLite3 (sqlite.org) SpatiaLite 2012 Concept initiated by GRL and NGA at a hosted technical exchange with FOSS / commercial software developers Started as Google Groups; moved to OGC due to need for standards development structure and potential IPR concerns Oct Standards Working Group charter established 2013-present OGC Web Services (OWS) Testbeds Phase 9 developed initial draft spec; others built prototype applications Feb Encoding Standard (1.0) adopted by OGC Early 2015 Corrigendum (1.0.1) adopted by OGC

6 GeoPackage Collaboration Industry LUCIAD Reinventing Geospatial Inc BITSystems Image Matters ESRI Digital Globe.. Government National Geospatial- Intelligence Agency Army Geospatial Center Geospatial Research Lab US Naval Research Lab Inter-governmental and industry collaboration on GeoPackage has created an unprecedented path in open standards

7 Where we were Redundant data AND applications tiles, tiles, tiles Reactive to emerging technologies 1 MBTiles n Spatialite Glue code to exchange information

8 Where we are Reduced data duplication Reduced glue code 1 2 n Shifting innovation to the application level SQLite Spatialite

9 Where we want to be Combination of open source and proprietary application solutions utilizing a single database 1 2 n Web Services Wide spread adoption of GeoPackage SQLite Spatialite SHP KML

10 Ongoing GeoPackage NGA R&D GeoPackage Java a Java implementation of the Open Geospatial Consortium GeoPackage spec. GeoPackage Core - provides core functionality for GeoPackage implementations of the Open Geospatial Consortium GeoPackage spec. GeoPackage Android- a SDK implementation of the Open Geospatial Consortium GeoPackage spec. WKB - a Java library for writing and reading Well-Known Binary Geometries to and from bytes. (Not GeoPackage Specific) GeoPackage MapCache - an app for Android that utilizes and demonstrates the functionality in the GeoPackage Android Libraries. ios coming soon

11 Ongoing GeoPackage NGA R&D

12 Ongoing GeoPackage GRL R&D GeoPackage Creation and Dissemination GeoPackage creation tools stand alone app Data management workflows Geopackage viewers OGC GeoPackage Creation Tools OGC GeoPackage Management

13 Ongoing GeoPackage GRL R&D Analytical Capabilities Spatial Engine Extensions / Libraries Routing (Topology) GeoPackage potential extensions Elevation Data Data Import / Export Utilities Geographic / Geodesic geometry types Additional Image MIME types (e.g. JPEG2000) Abstract Object Model and Non-SQL Encoding Symbology and Styling

14 Way ahead GeoPackage as a driver for open source software o Data Management o GeoPackage Extensions Continue to balance how standards are developed and imposed on our industry partners o Leverage the open source community o Proactive vs Reactive
