Discover what kind of GIS user you are and lay the foundation to evaluate the options and decide what software is best for you. Desktop GIS examines the challenges associated with assembling and using an OSGIS toolkit. You'll find strategies for choosing a platform, selecting the right tools, integration, managing change, and getting support. http://www.developerfusion.com/book/17373/desktop-gis-mapping-the-planet-with-open-source-tools/ http://www.developerfusion.com/book/17373/desktop-gis-mapping-the-planet-with-open-source-tools/ Wed, 09 Feb 2011 18:08:51 GMT Gary Sherman Jason takes you back to those high school geometry lessons and demonstrates how to take advantage of the new geospatial and geometric data types in SQL Server 2008. http://www.developerfusion.com/article/8325/spatial-data-in-sql-server-2008/ http://www.developerfusion.com/article/8325/spatial-data-in-sql-server-2008/ Wed, 09 Feb 2011 18:08:51 GMT Jason Follas Web apps to know where you are http://www.developerfusion.com/news/8252/mozilla-geode-exposes-the-local-web/ http://www.developerfusion.com/news/8252/mozilla-geode-exposes-the-local-web/ Wed, 09 Feb 2011 18:08:51 GMT James Crowley The NMEA data exported by GPS units gives latitude and longitude and geometric distance above the WGS84 (GRS80) reference ellipsoid. The Ordnance Survey maps for Great Britain use grid references based on the Airy Spheroid (OSGB36) reference ellipsoid. The following article discusses a C# class to convert GPS derived NMEA data to the British Ordnance Survey Grid. http://www.developerfusion.com/article/5507/gps-deriving-british-ordnance-survey-grid-reference-from-nmea-data/ http://www.developerfusion.com/article/5507/gps-deriving-british-ordnance-survey-grid-reference-from-nmea-data/ Wed, 09 Feb 2011 18:08:50 GMT Alex Etchells A VB6 version of Jon Person's .NET NMEA Interpreter Class as referenced in 'How to Write a GPS Application'. GPStest.zip contains the class and a simple project demonstrating implementation. http://www.developerfusion.com/code/5426/vb6-nmea-interpreter-class-for-reading-gps/ http://www.developerfusion.com/code/5426/vb6-nmea-interpreter-class-for-reading-gps/ Wed, 09 Feb 2011 18:08:50 GMT Alex Etchells In part two of the series, the author of "GPS.NET" teaches developers how to write GPS applications suitable for the real world by mastering GPS precision concepts. Source code includes a working NMEA interpreter and sample high-precision application in C# and VB.NET. http://www.developerfusion.com/article/4652/writing-your-own-gps-applications-part-2/ http://www.developerfusion.com/article/4652/writing-your-own-gps-applications-part-2/ Wed, 09 Feb 2011 18:08:49 GMT Jon Person An introduction to writing GPS applications in .NET good enough for use in a commerical environment such as in-car navigation. http://www.developerfusion.com/article/4634/writing-gps-applications-in-net-part-1/ http://www.developerfusion.com/article/4634/writing-gps-applications-in-net-part-1/ Wed, 09 Feb 2011 18:08:49 GMT Jon Person
