GeoPackage is often seen as a container that stores geospatial information, but at its core, GeoPackage is simply a SQLite database. This opens up a realm of possibilities to interact with and exploit its contents. We can incorporate advanced analysis into our data, or augment with other data types like basemaps, elevation, and other forms of media, all within the same package.

Usefully, GeoPackage can even accomplish offline Network Routing. Here's how.

In September 2018, the OGC/WMO Hydrology Domain Working Group (HDWG) held its ninth annual workshop marking ten years of successful collaboration between the World Meteorological Organisation (WMO) and OGC in hydrology and informatics. The working group has generated interoperability experiments, engineering reports, discussion papers, best practice documents, and four approved OGC standards - part of the WaterML2 suite.

This year marks the 20th anniversary of ApacheCon. For the last several years, we’ve had a strong representation at Apache from projects in the Geospatial sciences space. Just as collaboration is so important in the sciences, it is at Apache, and Apache seems to be a great fit for Geospatial projects, giving an open, collaborative way to work on the code that matters to Geospatial scientists, across the boundaries of corporations or research organizations. Through these projects, the ASF has forged a great relationship with OGC, and for the last couple of years we’ve had Geospatial tracks at ApacheCons in Vancouver, Seville, and Miami. This year at ApacheCon North America, in Montreal, we once again are excited to be featuring a track of Geospatial-focused talks, in cooperation with OGC.

The future of mapping is coming — or is it here already? With the advent of Indexed 3D Scene Layers (I3S) as a community standard, everyone stands to benefit.

An OGC GeoPackage is a portable database that may contain raster maps and imagery, vector features, and elevation data. GeoPackages are optimized for sharing and displaying these types of geospatial data on mobile mapping systems, and GeoPackage extensions may be developed to support additional types of geospatial data such as routing networks. This blog post will discuss what GeoPackage extensions are, how they are developed, and how they can provide new geospatial capabilities to meet the requirements of a diverse user base.

We live in a world stealthily powered by Web Services and APIs: nearly everything we do on our laptops and mobile devices uses background services to talk over the Internet. These services are especially important for applications providing access to small subsets of information, based on a user’s location, fed from large, remotely stored datasets. Any quality issues in the communication between the applications and their backend services quickly become critical, causing bad user experience for tens of thousands of people.
