Cartonama Conference

Making the most of geospatial data, community mapping, and location-based services.

The ‘Where’ question is central to our everyday lives. Geospatial data shapes our ability to answer that question and build intelligent applications, whether on the web or on your mobile device.

Supported by contributions from crowd-sourced data projects and open source software, geo data and its technology spectrum has grown impressively in recent years. In the face of this massive and diverse range of spatial data and technologies, the ability to choose effective methods for storage, retrieval and visualisation becomes critical .

The Cartonama conference is about geographic data, the technology behind it, the applications built around it and the overarching aspect of community and mobility.

We will organize workshops along with the conference. The goal would be to provide hands-on training to collect, store and visualize geographic data, and finally, to build location-based services with these tools. Workshop theme falls into:

  • Nature of Geospatial Data: Structure, Formats and Operations
  • Collection, Storage & Delivery of Geospatial Data: Crowd-sourced Models, Standards and Databases
  • Location-based Services: Front-end and Back-end tools to build and manage your applications
  • Leveraging Open Geographic Data Repositories: Using OpenStreetMap to visualize and tell stories through maps

You can submit your workshop proposals via the submissions through the funnel below.

##Speaking submissions
You can submit a proposal to speak at Cartonama via the submission funnel below. Please describe your proposal in as much detail as possible. Detail is important if you’d like to be voted up into the schedule.

Your submission will be up for public voting for up to 2 weeks before the event. For the final tally, we will only consider votes from ticket holders, as a way to ensure participants get exactly what they pay for.

Making a funnel submission does not guarantee final selection. Selected speakers will get a free ticket to the event (limited to one speaker per proposal). Proposers whose talks are not on the final schedule will be able to purchase tickets at the prevailing rate for the day on which they made their proposal.

You can buy a ticket to the event here.

Solving Where Am I Problem - Lokasi

Submitted Aug 28, 2012

GPS tells you the lat-long of your current location. Which is pretty much use-less to you or to your friend who wants to guide you. How exactly do you translate the simple machine understandable XY to something that you and I can decipher and is action-able?

You will learn to create a very simple and usable Where Am I kind of an application.


Lokasi does a (non-trivial) reverse geo lookup of your current location and tells you in human understandable and unambiguous way where you are. It can find out the nearest landmark for you and tell you distance from that. Once you get couple of landmarks you get a general sense of where you are without having to decipher your location on a google map.

You could then send that as SMS to your friend who will immediately know where you instead of having to look it up on google map.

In this talk we will walk through how we went about creating this app, what kind of data is required to support such a use case and how to provide the intelligent information from that data and your lat-long.


Just a basic understanding of what latitude and longitude is.
