This document discusses location-based solutions and mapping technologies. It begins by asking how big the market is for location-based startups in India and lists several positive factors like improved mobile positioning, GIS content, and user awareness. It then gives examples of common location-based apps like navigation and advertising. The document outlines the author's experience with technologies like maps generation, GIS data, and GPS devices. It recommends using Mapnik or Mapserver for mapping and TileCache for tile generation. It also discusses using OpenLayers, JavaScript, Ajax and jQuery for client-side development. In closing, it diagrams the author's approach to building such a system using components like PostGIS, Shapefiles, Mapnik and TileCache

1. LOCATION BASED
SOLUTIONS - MAPS & YOUR
LOCATION MATTERS!
26th Feb 2012 -Ritesh Ambastha, CEO – iWillStudy.com

2. 2012 - “The Year of LBS” in India?
How BIG is the
market for
location based
startups in India?

3. Good News
Mobile Positioning
GIS Content for LBS
Improvement in Handset Profiles
Increased Mobile Operators Interest for new VAS
Increased User Awareness
Development Tools & Platforms

4. LBS Apps – Yes, You use those daily

5. LBS Apps – Yes, You use those daily
Recommending social events in a city
Requesting the nearest business or service
Turn by turn navigation to any address
Locating people on a map displayed on the
mobile phone
Location-based mobile advertising

6. My Experiences
•Cell Triangulation
•Maps Generation
•Handling Shapefiles
•Cartography
•GPS Devices

7. Maps
Cartography
GIS Data
Maps Generation
Tiling
Front-End

8. GIS Engine - Web
 1. Mapserver
 2. Geoserver
 3. Mapnik
 4. Mapguide

9. My Suggestion – Mapping Engine
 Use Mapnik OR Mapserver
 Make beautiful maps
 Uses the AGG graphics library, which
offers world-class anti-aliasing
rendering with subpixel accuracy for
geographic data.

10. TileCache
 TileCache provides a Python-based
WMS-C/TMS server, with
pluggable caching mechanisms and
rendering backends.
 Generate tiles – 256x256 for Web
& 128x128 for Mobile (My
Recommendation)

11. Client Side Technologies
JavaScript
Ajax
jQuery

12. Open Layers
 Main supporter “MetaCarta”
 object-oriented JavaScript library (using Prototype.js and Rico library)
 Lets you add maps to any web page by embedding OpenLayer.js
 no server-side dependencies
 Easily reusable component
 ...similar to Google Maps and MSN Virtual Earth Web Mapping APIs
 “Slippy map style”
 Input Formats
 Tile sources: Virtual Earth, Worldwind, Yahoo & Google Maps, WMS
 Vector layer input: KaMap, MapServer, GeoRSS, WFS, [KML]
 Standard Tools
 Google Like zoom bar,
 standard functions
 like zoom in/out pan

13. GPS Coordinates
 Map Overlays
 Search Engine Query
(To be taken in
separate session)
 Refresh rates –
Updating Coordinates
