Great tool for cartography, geocoding, and data analysis

Quantum GIS is a cross-platform GIS application that supports many standard spatial data formats and provides an easy-to-use interface for basic GIS tasks. The software is free and open source, available for Mac OS X. As well as being an easy-to-use tool for developing maps and performing GIS analysis, it has many powerful features that allow you to create complex maps of all types.

Quantum GIS GUI

The Quantum GIS user interface is designed to be easy to use. The menu bar contains some options that allow you to perform common tasks such as opening and saving maps, providing access to editing tools, etc. The toolbars have buttons for common tasks such as zooming and panning, switching between map layers, accessing output formats, and more. Quantum GIS allows you to create many different types of map views, including 2D and 3D maps. The status bar contains information about the current map view and other details such as the current coordinates, scale, and projection information.


Quantum GIS offers a wide range of features for your GIS work. The following list provides an overview of some of the essential components:

Viewing data

Quantum GIS supports various viewing modes for maps, layers, and attribute tables: the map canvas, zoom, pan, layer selection, etc.

Maps composing and exploring spatial data Quantum GIS has many tools for collecting maps and interactively analyzing the data. These include drawing tools, measurement tools, reporting, 2D and 3D map rendering, map overlay controls, atlas map composition, etc.

Creating, editing, managing, and exporting data

Quantum GIS has a wide range of tools for creating, editing, and managing spatial data: from simple tools such as digitizing points and lines or drawing shapes using predefined geometry types to more advanced ones like network analysis, buffer analysis, raster edit, DXF-Export tool, raster calculator, etc.

Data analyzing

Quantum GIS allows you to analyze spatial data in various formats and perform analysis on vector and raster datasets. The app offers tools for sampling, geoprocessing, geometry, database management, and GRASS integration. You can also use the Processing plugin to run third-party algorithms from the app.

Publishing maps on the Internet

The easiest way is to use the publishing plugin, which allows you to create a WMS-C client or server. This client can be used to display your map on any WMS-compatible server. This is probably the best approach if you just want to publish your map on the Internet. However, if you want more control over your map's display and what it looks like, you should consider using a dedicated WMS server like GeoServer or MapServer.

Extending Quantum GIS functionality

The application is highly extensible, with a vast number of plugins available. This means it can be adapted to almost any purpose and provides an excellent base from which to build your own custom tools. If you want to extend Quantum GIS functionality, there are a couple of ways you can go about doing so: Topology Checker, Offline Editor, Geometry checker, and many more.


Quantum GIS is a powerful tool that can be used to build a wide range of applications. It's free and open-source so it won't cost you anything. If you want more control over your map's display and what it looks like, you should consider using a dedicated WMS server like GeoServer or MapServer
