Open Source GIS - Paul Bartsch & Joe Larson: talk given for San Luis Obispo GIS Users Group May 20th, 2009.

1. Free GIS an intro to open-source spatial software

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
