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

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

Why Location MattersFrom 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

Why Location Matters
The expression "Use a
picture. It's worth a
thousand words."
appears in a 1911
newspaper article
quoting newspaper
editor Arthur Brisbane
discussing journalism
and publicity.[1]

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.

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
www.upande.com
● 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

Call Detail Recording (CDR)

“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
