What is GeoPackage?
A single container for the storage and use of vector, raster, and tiled caches.
Available for use on a variety of mobile platforms.
• Described by a manifest.• Defined by an open standard, free of license.

Purpose and Motivation
Purpose: ► To introduce the GeoPackage concept to the open
source community. Motivation:
► GeoPackage responds to the need among government and non-government organizations to maintain situational awareness when constrained by limited or non-existent power or bandwidth.
► Involvement of the broader community is sought so as to converge on an open solution.
BUILDING STRONG®
Today
Effective coordinated large scale collaboration in military, homeland security, and disaster management relies upon the sharing of geospatial information.
An explosion of map applications for mobile handheld devices has resulted in a variety of incompatible data formats and interfaces.
No existing standard simplifies the provisioning of all types of geospatial data on assorted makes of mobile handheld devices.
BUILDING STRONG®
Objectives
Enable the distribution of packaged tile caches, raster, vector and descriptive data in an immediately useable form.
Realize capability from existing off-the-shelf solutions including commercial and open source software.
Engage developer community through appropriate forums to arrive at non-proprietary solution.
BUILDING STRONG®
Initial Use Case: Fixed Product Distribution
Geospatial information is collected, processed, analyzed, exploited, and packaged as data products in enterprise server environments
Distribution of the geospatial foundation by networked server or removable media
Products shareable throughout organizational levels and among all participants
GeoPackage stored once per platform to support multiple applications
BUILDING STRONG®
Additional Potential:
Local Data Collection ►Collection of observations ►Sharing of collected observations
Geospatially Enabled Analytics►Geocoding/reverse geocoding, ►Mobility analysis, ►Visibility analysis, and much more
BUILDING STRONG®
Initial GeoPackage Requirements
Manifest► Single self-describing file container to facilitate
management and distribution Tile Cache
► JPEG and PNG Tiles► Multiple Tile Matrices
Vector► Simple Geographic Features
Support direct access and update by apps
BUILDING STRONG®
Subsequent GeoPackage Requirements
Raster► Support “raw” raster formats for visualization and analysis
Elevation Data Coverages Routes Web Services
► for creation, management and distribution
Potential Manifest Extensions? ► Metadata► OGC Web Services (WMS, WMC, WFS, WCS)► Other Web Services (OpenStreetMap)

Current Plan
Identify, prototype, test and specify mechanisms for mobile geospatial data storage, transfer and use to meet identified requirements
Base the solution on existing consensus standards, other open specifications and existing technologies; don’t (re)invent unless absolutely necessary
Do this through an open public collaborative process involving key stakeholders in both the development and user communities
Demonstrate interoperability between key stakeholders Gain approval of a consensus GeoPackage specification Achieve widespread commercial and open-source
GeoPackage implementation In a one-year time frame

Summary
GeoPackage will meet a recognized need. An open specification is in the best interest
of the community. Collaboration is believed to be the most
effective way forward. Your participation is encouraged and
welcome.
