RE: [Qgis-user] Re: GPX, OS Grid References and Google Earth
If you are interested in accuracy of 10m or better then just check how the data are getting in, if its all coming from gps as wgs84 lat long then hopefully the conversion and plotting will be ok but if you are relying on the gps's version of the os grid then its liable to have errors often in the region of 7m. This error is on top of any location error on the gps unit itself, the error is simply due to conversion between wgs84 and os. http://onlinelibrary.wiley.com/doi/10./j.2041-210X.2011.00118.x/abstract I wrote a little about this but it's a generally known issue with consumer grade gps units and os grid. -Original Message- From: Des Callaghan [mailto:des.callag...@ecostudy.co.uk] Sent: 23 April 2012 14:58 To: qgis-user@lists.osgeo.org Subject: RE: [Qgis-user] Re: GPX, OS Grid References and Google Earth Many thanks Lene and Nick, this worked a treat.

As mentioned, import the GPX file to QGIS, then save it as a EPSG:27700 projected shapefile. To do this right-click on the GPX file in the layers panel, go 'Save As...' and set 'Format' to 'ESRI Shapefile'. Set the CRS for the new shapefile by clicking to the right of 'CRS', and picking 'Selected CRS', then press the 'Browse' button. In the window that appears enter '27700' (without the quotes) in the 'Filter' field. Highlight 'OSGB 1936 / British National Grid' in the list below and press 'OK'. Then give the new shapefile a name and click 'OK'. Next, load the new shapefile into QGIS, right-click on it in the layers panel and go 'Set Project CRS from Layer'. You can now add OS grid coordinates to the shapefile's attribute table. To do this, highlight the layer in the layers panel and (from the top menu bar) go Vector -> Geometry Tools -> Export/Add geometry columns. All you need to do here is tick 'Save to new shapefile', give the new file a name and press 'OK'. Now load the new shapefile and have a look at the attribute table (right-click on the layer in the layers panel and go 'Open Attribute Table'). You should find that it contains two new columns, one for OS eastings (x-ordinates) and the other for northings (y-ordinates). The ordinates form OS grid coordinates, not grid references (ie. SD4568798345 will be shown as 345687 498345, for example). QGIS doesn't know about Ordnance Survey grid references I'm afraid, but if this is a problem then come back.

OGRS2012 :: SECOND CALL FOR PAPERS (closing at May 28th) Open Source Geospatial Research and Education Symposium October 24 – 26, 2012 in Yverdon-les-Bains, Switzerland Hosted by School of Business and Engineering Vaud (HEIG-VD) Website: http://www.ogrs2012.org Contact: c...@ogrs2012.org Notice, PDF version of this call is available here : http://cfp.ogrs2012.org. - (our apologies for cross-postings) Dear colleagues, The Open Source Geospatial Research and Education Symposium (OGRS) is a meeting dedicated to exchanging ideas on development and use of open source geospatial software in both research and education. Motivated by the inaugural symposium in Nantes, France, OGRS2012 will be held from October 24 – 26, 2012 in Yverdon-les-Bains, Switzerland. The symposium is hosted and organized by the School of Business and Engineering Vaud (HEIG-VD), in partnership with EPFL Lausanne, University of Lausanne, University of Geneva, which are all academic institutions in Western Switzerland, and the Institute for Research on Urban Sciences and Techniques in France. The main goals are: - to build a panel of new scientific research and education practices using and contributing to open source initiatives in the geospatial fields; - to discuss a framework and highlight a rationale about geospatial open source technology usage in research and education activities; - to provide an innovation platform to network and develop ideas for future collaborative work between academia – from research to education – and other actors of the field (associations, foundations, local authorities, industry etc.). For more details, visit the overview page on the website. Keynote speakers : - Luc Anselin, Director, Regents' Professor and Walter Isard Chair at School of Geographical Sciences and Urban Planning, College of Liberal Arts and Sciences and Director at GeoDa Center for Geospatial Analysis and Computation, Arizona State University; - Gérard Hégron, Scientific Director in charge of sustainable city at IFSTTAR (French Institute of Science and Technology for Transport, Planning and Networks); - Helena Mitasova, Associate Professor at Department of Marine, Earth and Atmospheric Sciences, North Carolina State University; - Robert Weibel, Professor of Geographical Information Science at Department of Geography, University of Zürich. Submission : The symposium will integrate several opportunities for presenting : oral presentations, workshops, posters and discussion groups. To participate in any of these opportunities, authors are invited to submit an extended abstract (1000 to 1500 words, references and keywords excluded) through the conference website. The official language is English. The international scientific advisory board will review and select abstracts for inclusion in the symposium and publication in the symposium proceedings. A subset of contributions will be invited to submit full papers for possible publication in a special issue of the Journal of Spatial Information Sciences (JOSIS), pending a peer review of full papers. For more details on how to submit a contribution, please visit the call for papers page on the website : http://cfp.ogrs2012.org. Important dates : - submission deadline for abstracts is May 28, 2012. - authors will be notified by June 30, 2012 on program inclusion and selection for JOSIS submission - deadline to submit full papers is September 30, 2012. We would appreciate if you could kindly distribute this call to other interested parties of your acquaintance.

[Qgis-user] Re: GPX, OS Grid References and Google Earth
Hi Des, just to add a lttle to what Lene wrote. As mentioned, import the GPX file to QGIS, then save it as a EPSG:27700 projected shapefile. To do this right-click on the GPX file in the layers panel, go 'Save As...' and set 'Format' to 'ESRI Shapefile'. Set the CRS for the new shapefile by clicking to the right of 'CRS', and picking 'Selected CRS', then press the 'Browse' button. In the window that appears enter '27700' (without the quotes) in the 'Filter' field. Highlight 'OSGB 1936 / British National Grid' in the list below and press 'OK'. Then give the new shapefile a name and click 'OK'. Next, load the new shapefile into QGIS, right-click on it in the layers panel and go 'Set Project CRS from Layer'. You can now add OS grid coordinates to the shapefile's attribute table. To do this, highlight the layer in the layers panel and (from the top menu bar) go Vector -> Geometry Tools -> Export/Add geometry columns. All you need to do here is tick 'Save to new shapefile', give the new file a name and press 'OK'. Now load the new shapefile and have a look at the attribute table (right-click on the layer in the layers panel and go 'Open Attribute Table'). You should find that it contains two new columns, one for OS eastings (x-ordinates) and the other for northings (y-ordinates). The ordinates form OS grid coordinates, not grid references (ie. SD4568798345 will be shown as 345687 498345, for example). QGIS doesn't know about Ordnance Survey grid references I'm afraid, but if this is a problem then come back.
