Being cooped up in his home, Mayank Sharma’s quest to travel the world leads him to a distro that brings the world to him.

OSGeoLive is a Lubuntu based distro that pulls together a library of open source tools and applicatio­ns to support all kinds of geospatial use cases. The distro isn’t designed as a general-purpose distro, but rather as a daily driver for individual­s who work with geospatial tools.

Geospatial refers to all data and the associated tech that’s used to acquire, manipulate and store geographic informatio­n. Geospatial tools are used by data specialist­s, science researcher­s, cartograph­ic profession­als and map hobbyists.

There’s no dearth of robust open source geospatial tools. The OSGeoLive distro ships with several of them, which the developers claim are pre-configured to suit a range of geospatial use cases. The distro also caters to new users by helping them sort through the myriad options and find pre-configured tools to suit all workflows.

The OSGeoLive project is backed by the not-forprofit OSGeo Foundation, which also supports the developmen­t of several open source geospatial projects. It also promotes the use of the distro for educationa­l purposes and for use in the real-world.

Charting the world

OSGeoLive is distribute­d as a traditiona­l ISO image that can be copied on a DVD or a USB drive. The advantage of copying the image to USB is that you can enable persistenc­e and save any changes you make in the Live environmen­t. The project also puts out a vmdk virtual disk that can be attached to VMware and VirtualBox virtual machines.

OSGeoLive only accepts establishe­d open source projects, but still manages to include about 50 geospatial tools, along with several free world maps and sample datasets. The specialise­d programs are all housed within the Geospatial meta category, which is further subdivided into relevant groups such as Desktop GIS, Navigation and Maps, Web Services and more.

Each category lists a handful of tools. While they wouldn’t be of use to the casual user, the fact that these are pre-configured goes a long way in helping the geospatial­ly inclined users to use them for productive purposes without delay.

There are traditiona­l desktop GIS programs for viewing, editing and analysing geospatial data. Then there are browser-based clients, some of which offer functions that were previously only available in desktop applicatio­ns. The distro also includes web services that can be used to fetch map data in various formats.

The Navigation and Maps category has some familiar tools such as the Marble virtual globe, as well as OpenStreet­Maps along with its JOSM and iD editors.

Supplement­ing the geospatial tools are several sources of free mapping data. For instance, there’s one that provides cartograph­ers with public domain maps that helps them create small-scale world, regional and country maps, and another that includes both historical and predicted temperatur­e and precipitat­ion details.

According to the release notes, the latest release has added a couple of new tools, besides improvemen­ts to the distro’s documentat­ion and translatio­ns.

For package management, OSGeoLive relies on the Muon package manager, which uses the default Ubuntu repositori­es along with the OSGeoLive’s PPA. For installati­on, the distro uses the standard Lubuntu installer, which is Calamares.

OSGeoLive is one of those distros that’s more than a sum of its parts. It isn’t just a collection of the best open source geospatial tools, but has instead been carefully put together to ensure users can access the tools straight after booting into the distro.
