An Initiative forStandardized Geospatial Formats

Optimized for Mobile

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.

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)

What else?

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.
