  3. 3. S S (c) Upande 2014 Why Location Matters What is Location? ● Location (one of the 5 geographic themes) is a specific position or point in physical space, a point or an area on the Earth's surface ● A relative location is described as a displacement from another site—for example, "1000 kilometers northeast of Nairobi". ● Absolute location, describing a position on the surface of the Earth Source: wikipedia
  4. 4. S S (c) Upande 2014 Why Location Matters Maps ● A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes (wikipedia). ● Maps can be 2D/3D, more/less accurate, various projections/scales, static/dynamic ● Traditionally only represent geography, now any ‘space’ ● Maps have been around for centuries
  5. 5. S S (c) Upande 2014 Why Location Matters From Cartography to GIS to Web Mapping ● Cartographers, infrastructure designers both started getting interested in digital storage in the 1980s ● Geographical Information Systems (GIS) opened up way for storing any kind of data (census, climate, business) a. What is at this location? (across layers) b. Where is X, something specific? (across layers) c. When was this? (time series, across layers) ● Google helped fasttrack webmapping interest (2004) ● OSM and OGC based FOSS growing fast, custom tiles ● Common: Location as unifier across layers/themes

  15. 15. S S (c) Upande 2014 Why Location Matters Cartograms A cartogram is a map in which some thematic mapping variable – such as income, population, or Gross National Product – is substituted for land area or distance. The geometry or space of the map is distorted in order to convey the information of this alternate variable.

  26. 26. S S (c) Upande 2014 Mobile Analytics ● Real time indoor location tracking: real time heat maps and location (context) aware apps/services for indoor public venues ● Location analytics: predict future movement behaviours and activities of individuals and groups ● Group detection and group dynamics: mining of mobile sensing data for understanding individual/group activity in physical world ● Queue detection: traffic, queues at buildings, food courts, taxi stands ● Socio-physical Analytics: combined physical world movement and online usage to detect user preferences, interests and activities
  27. 27. ● Mobile operators track unique lines and can accurately triangulate location at any one time ● Linked to SMS registration, phone purchases, internet usage, they are able to build detailed profiles of users: age, interests, places visited, etc. ● Big Data analysis will show commuting behaviour, movement in day, movement inside malls, where are they spending how much time, etc. ● It will allow to plan where to build new facilities, business locations ● Using live data it will be possible to show relevant ads based on the users in the area (c) Upande 2014 Call Detail Recording (CDR)
  28. 28. “Location has never been more important than now, because:” ● Mobile call tracking, CCTV, Internet of Things are becoming mainstream. ● BigData is becoming mainstream, being able to digest and make sense of such volumes of data ● Context driven Location Based Services (LBS) Market worth $40 Billion by 2019 Data Driven Journalism requires context analysis which often means taking location into account (c) Upande 2014 Why Location Matters
