地理情報システム (GIS)のすばらしい世界へようこそ! Quantum GIS (QGIS) はオープンソースのGISです. このプロジェクトは2002年5月に開始 され、同じ年の6月 SourceForgeのプロジェクトを立ち上げました。 We've worked hard to make GIS software (which is traditionally expensive proprietary software) a viable prospect for anyone with basic access to a Personal Computer. QGIS currently runs on most Unix platforms, Windows, and OS X. QGIS is developed using the Qt toolkit http://www.trolltech.com and C++. This means that QGIS feels snappy to use and has a pleasing, easy-to- use graphical user interface (GUI).
QGIS aims to be an easy-to-use GIS, providing common functions and features. The initial goal was to provide a GIS data viewer. QGIS has reached the point in its evolution where it is being used by many for their daily GIS data viewing needs. QGIS supports a number of raster and vector data formats, with new format support easily added using the plugin architecture (see Appendix appdx_data_formats for a full list of currently supported data formats).
QGIS is released under the GNU General Public License (GPL). Developing QGIS under this license means that you can inspect and modify the source code, and guarantees that you, our happy user, will always have access to a GIS program that is free of cost and can be freely modified. You should have received a full copy of the license with your copy of QGIS, and you also can find it in Appendix gpl_appendix.
Tip 1 Up-to-date Documentation
The latest version of this document can always be found at http://download.osgeo.org/qgis/doc/manual/, or in the documentation area of the QGIS website at http://qgis.osgeo.org/documentation/

特徴
QGIS は通常のGISの機能を本体のコア機能と多くのプラグインで提供してます。 ここでは簡潔に6つのカテゴリーに分けて特徴を説明します。
データを見る
異なる形式、投影法のベクタ、ラスタデータを内部形式に変換することなくそのまま 閲覧したりオーバーレイ表示することができます。 利用できるデータ形式は以下の通りです。
- item spatially-enabled PostgreSQL tables using PostGIS, vector formats \footnote{OGR-supported database formats such as Oracle or mySQL are not yet supported in QGIS.} supported by the installed OGR library, including ESRI shapefiles, MapInfo, SDTS and GML.
- Raster and imagery formats supported by the installed GDAL (Geospatial Data Abstraction Library) library, such as GeoTiff, Erdas Img., ArcInfo Ascii Grid, JPEG, PNG.
- SpatiaLite databases (see Section label_spatialite)
- GRASS raster and vector data from GRASS databases (location/mapset),
- Online spatial data served as OGC-compliant Web Map Service (WMS) or Web Feature Service (WFS).
データの探索と地図の構成
You can compose maps and interactively explore spatial data with a friendly GUI. The many helpful tools available in the GUI include:
- item on the fly projection
- item map composer
- item overview panel
- item spatial bookmarks
- item identify/select features
- item edit/view/search attributes
- item feature labeling
- item change vector and raster symbology
- item add a graticule layer now via fTools plugin
- item decorate your map with a north arrow scale bar and copyright label
- item save and restore projects
データの作成、編集、管理と出力
You can create, edit, manage and export vector maps in several formats. Raster data have to be imported into GRASS to be able to edit and export them into other formats. QGIS offers the following:
- item digitizing tools for OGR supported formats and GRASS vector layer
- item create and edit shapefiles and GRASS vector layers
- item geocode images with the Georeferencer plugin
- item GPS tools to import and export GPX format, and convert other GPS formats to GPX or down/upload directly to a GPS unit (on Linux, usb: has been added to list of GPS devices)
- item create PostGIS layers from shapefiles with the SPIT plugin
- item improved handling of PostGIS tables
- item manage vector attribute tables with the new Attribute table (see Section attribute table ) or Table Manager plugin
- item save screenshots as georeferenced images
データ解析
You can perform spatial data analysis on PostgreSQL/PostGIS and other OGR supported formats using the fTools python plugin. QGIS currently offers vector analysis, sampling, geoprocessing, geometry and database management tools. You can also use the integrated GRASS tools, which include the complete GRASS functionality of more than 300 modules (See Section grass).
インターネットへの地図公開
QGIS can be used to export data to a mapfile and to publish them on the internet using a webserver with UMN MapServer installed. QGIS can also be used as a WMS or WFS client, and as WMS server.
プラグインを使ったQGIS機能の拡張
QGIS can be adapted to your special needs with the extensible plugin architecture. QGIS provides libraries that can be used to create plugins. You can even create new applications with C++ or Python!
- Core Plugins
- Add WFS Layer
- Add Delimited Text Layer
- Coordinate Capture
- Decorations (Copyright Label, North Arrow and Scale bar)
- Diagram Overlay
- Dxf2Shp Converter
- Georeferencer
- fTools
- GPS Tools
- GRASS integration
- Interpolation Plugin
- OGR Layer Converter
- Quick Print
- SPIT Shapefile to PostgreSQL/PostGIS Import Tool
- Mapserver Export
- Python Console
- Python Plugin Installer
- Python Plugins
- QGIS offers a growing number of external python plugins that are provided by the community. These plugins reside in the the official PyQGIS repository, and can be easily installed using the python plugin installer (See Section plugins).
