[OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?
I'm giving a presentation on GeoSpatial Open Source at the international Surveyors conference here in Sydney. http://www.fig2010.com/ I'd like advice on what use cases and Open Source packages I should focus on during the presentation.

Re: [OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?
Well we have surveyors trialling Total Open Station into gvSIG and people using Leica's software into gvSIG; I guess here is the message that into GIS is a move forward for all but building survey and that there are open source GIS packages well up to the job. And for building survey? Well, we're doing some work with various open source tools to generate dense point clouds from photos; we think the resulting output could reach millimetre accuracy using known cameras/lenses and with many shots. Photograph, process, measure at your leisure... And a lovely 3D photo-realistic model for client as an output too! Does that count?

Dear Cameron if you are interested also in LiDAR data filtering (to obtain from the LiDAR point cloud the digital terrain model), we developed commands into GRASS. They have to be used in sequence. http://grass.osgeo.org/gdp/html_grass64/v.lidar.edgedetection.html http://grass.osgeo.org/gdp/html_grass64/v.lidar.growing.html http://grass.osgeo.org/gdp/html_grass64/v.lidar.correction.html http://grass.osgeo.org/gdp/html_grass64/v.surf.bspline.html A detailed description is available here: http://www.foss4g2006.org/getFile.py/access?contribId=48sessionId=59resId=7materialId=slidesconfId=1 a more recent and summarised version can be found here: http://geomatica.como.polimi.it/corsi/remote_sensing/LiDAR_filtering_with_GRASS-lab4.pdf We worked also on calibration of the filtering parameters (around 20 parameters) by integrating the USGS UCODE and GRASS. Details are available here: http://www.isprs.org/proceedings/XXXVIII/1_4_7-W5/paper/Brovelli-126.pdf I hope it helps. Cheers.

Re: [OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?
Thank you Marina, That is a good example. To be complete, could you also answer: * What would be the proprietary equivalent software you would use? * Why did you decide to use GRASS instead of proprietary software? (Hopefully more than it was cheaper) * It seems you are officiated with a University? Industry is more convinced by case studies that come out of industry, as universities are often associated with smart geeks, who have a high tollerance to things going wrong because they can fix it themselves. Is there a non-education affilition you can draw upon? Did you do this work for a governement department or similar? maria.brove...@diiar-topo.polimi.it wrote: Dear Cameron if you are interested also in LiDAR data filtering (to obtain from the LiDAR point cloud the digital terrain model), we developed commands into GRASS.

Hi Cameron, You might find these Oxford Archaeology produced guides interesting: http://openarchaeology.net/project/survey-and-gis-manual There's also the MapAction Field Guide to Humanitarian Mapping: http://www.mapaction.org/content/view/183/59/ If you're looking for a couple of real feel good use cases (although I can imagine it may not be 100% applicable to what you're doing), there's the amazing work conducted by various people (Mikel Maron and Robert Soden spring immediately to mind, although there are many more) mapping Haiti and Kibera, Kenya into OpenStreetMap.

Cameron, Most of the material from my slide show can be downloaded here: http://www.redefinedhorizons.com/introduction_to_vector_gis_for_land_sur veyors.html I think the only thing that is missing will be the speaker outline. I adhere to the slide:ology method of slide show presentations, so most of my slides have little text. Most of the presentation meat is in my speaker outline. If you provide me with a private e-mail I will send you my speaker outline.

Ladon, Thank you, your presentation sounds like an excellent basis for my presentation. Please send it through.

Landon Blake wrote: Cameron, I recently gave a presentation entitled introduction to vector GIS for land surveyors at the joint California Land Surveyor Association/Nevada Association of Land Surveyors Annual Conference in Reno, Nevada. It included demonstrations of how to use OpenJUMP in a land surveying practice. I would be happy to share the materials from my presentation with you. I currently use OpenJUMP to perform the following tasks in my own survey practice: - Project Planning - Parcel Management - Preparation of GIS Deliverables from Survey/CAD Data I also have written some AutoLISP routines that help improve CAD/GIS integration. I haven't put in as much time on this as I want to, but my code does currently support export of WKT geometries from CAD using AutoLISP. Let me know if any of this is helpful.

Currently, I am looking for a student position / work experience internship in the fields of GIS or location based services development. My preferred locations are New Zealand, Australia or Canada, but I could basically imagine to work anywhere. The internship should take at least twelve weeks and start around June. I am working in relevant jobs alongside my studies, so I already have some work experience and insight in development workflows. I will only be able to accept a paid internship enabling me to cover at least the basic cost of living, or alternatively a position with accomodation provided. If you know a company or organization that may be interested in employing a dedicated, hard working intern, please let me know. I'll appreciate any information.
