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

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
