4. FOSS4G : Free and Open Source Software for Geospatial OSGEO : The Open Source Geospatial Foundation All of the products we'll talk about today are both free and open-source
14. GeoServer Outputs: WMS, WFS, KML, GeoJSON, GeoRSS, more.. Share and edit geospatial data Open standards allow publishing from any major spatial data source including: shapefiles, SQL Server, PostGIS, DB2, Oracle, WFS, TIFF Images, MySQL Integrates with existing API's (Google, yahoo, etc.) Connects to ArcGIS Server WMS can be easily added into existing ArcMap .mxd's http://geoserver.org/display/GEOS/Welcome GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards…GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.
16. OpenLayers JavaScript Library, including API Similar to Google Maps API Makes building dynamic mapping webpages VERY easy Provides the tools needed to easily add a map to a webpage Allows overlaying your own data Can display map tiles and markers loaded from any source http://openlayers.org/ OpenLayers: http://www.openlayers.org/ OpenLayers makes it easy to put a dynamic map in any web page. It can display map tiles and markers loaded from any source…OpenLayers is a pure JavaScript library for displaying map data in most modern web browsers, with no server-side dependencies. OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographic applications, similar to the Google Maps and MSN Virtual Earth APIs, with one important difference -- OpenLayers is Free Software, developed for and by the Open Source software community.
17. GRASS Geographic Resources Analysis Support System Geospatial data management Analysis Image processing Graphics/maps production Spatial modeling Visualization Tons of tools + functions = Very complex analysis Now there's a simple user interface through QGIS Commonly referred to as GRASS, this is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is an official project of the Open Source Geospatial Foundation. http://grass.osgeo.org/
18. OSSIM Open Source Software Image Map C++ software library that provides advanced remote sensing, image processing, and geo-spatial functionality Includes orthorectification, precision terrain correction, rigorous sensor models, very large mosaics, and cross sensor fusions, a wide range of map projections and datums, and a large range of commercial and government data formats OSSIM Planet - an accurate 3D global geo-spatial viewer that is built on top of OSSIM
19. Quantum GIS (QGIS) Desktop application – very user friendly Can work directly with .shp file, WMS, too many to list Any Platform – Windows, Mac, Linux FREE Plugins available (Similar to Firefox add-ons) Allow spatial analysis, 3-D analysis, statistical analysis... User interface for GRASS tools. OGR interface allows use of TONS of formats PostGIS interface MapServer export www.qgis.org
20. The OGR Simple Features Library is a C++ open source library (and commandline tools) providing read (and sometimes write) access to a variety of vector file formats including ESRI Shapefiles, S-57, SDTS, PostGIS, Oracle Spatial, and Mapinfo mid/mif and TAB formats. GDAL is a translator library for raster geospatial data formats...It also comes with a variety of useful commandline utilities for data translation and processing. GDAL, OGR
21. With GDAL tools you can: Report information about a file. Copy a raster file, with control of output format. Warp an image into a new coordinate system. Build a MapServer raster tileindex. Convert nearly black/white borders to exact value. Contours from DEM. Create a TMS tile structure, KML and simple web viewer. Tools to analyze and visualize DEMs. Build a quick mosaic from a set of images. Rasterize vectors into raster file. Transform coordinates. And much more… Possible OGR Sources in QGIS: AVCBin, BNA, CSV, DGN, ESRI Shapefile, GML, GMT, GPX, GRASS, GeoJSON, Interlis, KML, MapInfo FIle, Memory, MySQL, ODBC, OGDI, PGeo, PostgreSQL, REC, S57, SDTS, SQLite, TIGER, UK.NTF, VRT Possible OGR Targets in QGIS: BNA, CSV, DGN, ESRI Shapefile, GML, GMT, GPX, GeoJSON, Interlis 1, Interlis 2, KML, MapInfo FIle, Memory, MySQL, ODBC, PostgreSQL, S57, SQLite, TIGER

Notas do Editor
The common misconception with anything free is that there is something wrong with it. New Coldplay album was just given away for free to their fans. My first thought was that the sound of the album would be poor/ that the songs would be up to par with their other albums. But I downloaded it anyway since its free, and it turns out to be a really great album. www.coldplay.com

Imagine if all past knowledge was kept hidden or its use was restricted to only those who are willing to pay for it. Education and research would suffer. Publishing books or sharing information of any sort would become difficult. Yet this is the mentality behind the proprietary software model. In the same way shared knowledge propels the whole of society forward, open technology development can drive innovation for an entire industry. http://www.redhat.com/about/whyopensource/
Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, and Windows and supports numerous vector, raster, and database formats and functionalities. Quantum GIS provides a continously growing number of capabilities provided by core functions and plugins. You can visualize, manage, edit, analyse data, and compose printable maps. Get a first impression with some screenshots and a more detailed feature list. Quantum GIS is a volunteer driven project. We welcome contributions from in the form of code contributions, bug fixes, bug reports, contributed documentation, advocacy and supporting other users on our mailing lists and the QGIS Forum. If you are interested in actively supporting the project, you can find more information under the development menu and on the QGIS Wiki. We also welcome financial contributions in the form of sponsoring and funding.
OSGeo4W A binary distribution of a broad set of open source geospatial software for Win32 environments (Windows XP, Vista, etc). Includes GDAL/OGR , GRASS , MapServer , OpenEV , uDig , QGIS as well as many other packages (about 70 as of summer 2008). http://trac.osgeo.org/osgeo4w/
