Re: [OSGeo-Discuss] Seeking guidance for contributing to OSGeo.
Hi, The first national FOSS4G conference is about to happen on this month 25-27. I think registrations are still open[1]. The conference is held at IIIT-Hyderabad, India. please see the program schedule [3] [1] http://lsi.iiit.ac.in/foss4gindia/ [2] http://iiit.ac.in/ [3] http://lsi.iiit.ac.in/foss4gindia/?q=tentative-program-schedule On Sun, Oct 14, 2012 at 8:38 AM, Jody Garnett jody.garn...@gmail.comwrote: Afternoon: OSGeo is a Foundation, as such there are lots of projects to look at. Perhaps one of them strikes your interest? If you are unsure where to start I recommend volunteering on the OSGeo Live DVD project (http://wiki.osgeo.org/wiki/Live_GIS_Disc) which is a good introduction to what is available. Finally OSGeo does have individual chapters in each region - including one in your area (http://wiki.osgeo.org/wiki/India). I recommend having a look at their activities, and introducing yourself on their mailing list.

I have a prior experience in Geographical Information Systems (GIS). As a summer trainee under Defense Research and Development Organization, Ministry of Defense, India; I worked on a project titled Development of PostgreSQL to OpenMap interface for basic vector overlay. OpenMap is an open source GIS Tool that enables us to work on various set of map data. In order to create overlays, OpenMap GIS provides the functionality to create basic set of overlays which include point, line, polyline, polygon, splines etc. I was assigned a task to establish a connection between OpenMap and PostgreSQL using JDBC, with the aim of storing the overlays drawn on any particular layer of OpenMap along with its user given unique name and attributes, which may be retrieved as and when required. Kindly guide me on how I can start and make my contribution. I look forward to a positive response from you. Thanking You.

[OSGeo-Discuss] ossimPredator KLV data
All, Where can I get some KLV data for testing ossimPredator? No KLV data is public and hence ossim developers cant put it on their repo. So Is there anyway we can generate it since getting existing test data is not possible. Even though ossimPredator has a very small code base its very important.

Re: [OSGeo-Discuss] Displaying vector files
Hi Akshay, There is QGIS[1] which does both raster and vector rendering and a lot of things more that you need. You can develop a small application using QGIS as library. You need to link your application with qgis_core and qgis_gui. There are some nice tutorials written by tim sutton[2]. and QGIS uses Qt and cross platform [1] qgis.org [2] http://blog.qgis.org/taxonomy/term/1 On Wed, May 9, 2012 at 7:00 PM, akshay gupta akshaygupta...@gmail.comwrote: Hi all, I am writing an application to load vector maps/shape files using gdal/ogr and display them onto a gui designed using Qt. I am new to dealing with vector files, I am not able to decide how to render them on GUI. Few approaches that come to my mind are: - To convert vector files to raster and display them as raster.. - To draw each shape in vector file one by one (i dont know how to do this, I dont even know whether it would be even possible this using GDAL/OGR, or how complex this would be because in my case vector files can be very complex) The decision how to render vector files is very important for me, because after displaying vector files i need to support some advanced features like projection change, interactive selection, Geo-referencing etc. Can any one who has worked on vector/gis stuff, tell me how this is usually done and what Qt widget is used for displaying such data.

Hi all, Here is GRASS GIS Web UI connected with OpenLayers widget http://lsi.iiit.ac.in/lsi/wgrass The app is under development and is released for initial testing. For testing purpose we fix a lat/lont location and concentrate on vector data Location Info: extent -180,-90,180,90 mapset PERMANENT you can import any grass vector data using v.in.ogr and display it in OL using d.vect For Listed GRASS modules: 1. Type on search box on top for list and select a module and hit enter or click search 2. you will get a menuForm of the selected GRASS module. 3. Fill all the attributes and click run to execute the grass module. You can also run any grass command v.* or r.* using this webUI which is unlisted please test it Any comments, suggestions, BUGS are always welcomed.. -- Thanks Regards Rashad ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
Re: [OSGeo-Discuss] Android vector renderer
OpenLayers cannot render shapefile directly but using mapserver it can we use gdal which can render more format than OpenLayers changing shapefile viewer to Vector viewer for android is a change of single line in code :) see http://www.gdal.org/ogr/ogr_formats.html Reason2: we need a shapefile viewer which works on both desktop and android phones (symbian is also possible) The Online Shapefile viewer does need to make any changes in source to run on android. It needs only recompilation So we have two supported platform in one. If we use OpenLayers we need to use OpenLayers mobile for android and OpenLayers for PCs for web and also we need to make some changes in source of OpenLayers when we switch between different mobile platforms http://www.gdal.org/ogr/ogr_formats.html On Fri, Apr 29, 2011 at 1:55 PM, Andreas Hocevar ahoce...@opengeo.orgwrote: Hi, why not use OpenLayers then?
