Objective

One can learn about the following by attending the lecture: 1. Open sources of geodata 2. Tools to process such data 3. Indexing them to build a simple location-enabled search engine

Description

  1. Open sources for location information associated with structured and semi-structured data Wikipedia, DBPedia, Freebase, Geonames, US Military database etc.
  2. Tools and methods to process the identified feeds: Google Refine, RDF libraries, custom feed processors
  3. Building a simple search engine using the data processed above to support the following: Point, range, and neighbourhood searches

Draws from my experience extracting information from various online sources for building a mobile search engine (zook.in) as well as for building custom search systems at Ideophone.

Requirements

A basic idea of the following: 1. geodata 2. webservices
