改變中的地理資訊
Monday, July 15, 2013
地理資訊
• 地圖是地理空間資訊的載體,
而地理資料呈現地圖的基礎
• 廣義而言,具有地理參照
(geo-reference)的資料都可稱
為地理資訊
• 地理坐標是清楚的地理參照,
而地名、地址、郵遞區號、電
線桿...等只要可以對應到地表
空間上的真實位置都可以是地
理參照

GPS的普及
• 美國於2000年解除人為干
擾  (SA, Selective
Availability),民用的GPS
提高了定位精度
• 如今,GPS裝置是智慧型
手機的基本配備
• 利用智慧型手機拍照和發
送訊息都可以附加上地理
標籤(Geotag)
• 人人都可以生產地理資訊

OSM的架構
Geodata Editing Backend Rendering Visualization
Monday, July 15, 2013
Backend
Monday, July 15, 2013
Backend database: PostgreSQL
• OSM doesn’t use geometry type of PostgreSQL
and geospatial functions of PostGIS.
• OSM API v0.6 is used for the main central OSM
DB running on servers.
• http://wiki.openstreetmap.org/wiki/API_v0.6
• Osmosis is used to populate a more general
PostgreSQL/PostGIS DB from Planet.osm dump
file.
• http://wiki.openstreetmap.org/wiki/Osmosis
Monday, July 15, 2013
Rendering system
Monday, July 15, 2013
Mapnik
www.mapnik.org
• OSM uses Mapnik to render 256 X
256 pixels tiles
• osm2pgsql is used to convert OSM
data to postgreSQL for Mapnik
rendering
• Map sytles are controlled by
stylesheet (XML) files.
• Useful tutorial! https://github.com/
mapnik/mapnik/wiki/MapnikTutorials
Monday, July 15, 2013
Mod tile
• Mod tile is a system to serve tiles, for
example to use within a slippy map.
• The implement of Mod file is split into two
ports
• mod_tile is a custom Apache module
which is responsible for serving tiles and
requests the rendering of tiles
• renderd - A rendering daemon which calls
mapnik and writes the map tiles to the
filesystem
Monday, July 15, 2013
tile@home
• Tiles@home (short:T@H or tah) is a distributed
program to render Osmarender maps.
• T@H has a server software,Tahngo (generation
2), running at the Tiles@home website, which get
requests to render tiles from updated mapdata.
Monday, July 15, 2013
Visualization
Monday, July 15, 2013
Slippy map
• The slippy is an Ajax component. JavaScript runs in the
browser, which dynamically requests tiles from the
server in the background (without reloading web page)
to give a smooth map browsing experiences.
• The implementation of slippy map is mostly provided
by OpenLayers
• The tiles rendering usually comes from two resources
• Mapnik tile rendering
• Osmrender (tiles@home) tile rendering
