Maps

Cartography

GIS Data

Maps Generation

Tiling

Front-End

GIS Engine - Web

1. Mapserver

2. Geoserver

3. Mapnik

4. Mapguide

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.

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)

Client Side Technologies

JavaScript

Ajax

jQuery

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

GPS Coordinates

Map Overlays

Search Engine Query

(To be taken in

separate session)

Refresh rates –

Updating Coordinates

My way of looking at this system

Shapefiles

(GIS Data)
