Re: [OSGeo-Discuss] Android vector renderer
Hi, why not use OpenLayers then? It works on Android, can read vector data files, gives programmatic access to the features and geometries, and supports the creation of vector features. And if wrapped in PhoneGap or Titanium, it will also give you write access to the file system. Andreas.

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?

Re: [OSGeo-Discuss] Re: FOSS4G program community voting now open!
Hi Bob, No, there isn't a url with selection criteria. We are using the same process as in previous years. The primary factor in selection is what the community deems to be interesting, as indicated by the results of this poll. The conference organizing committee uses that as input to decide on the final program. One of the main things the committee will consider in making adjustments is the balance of the program - we will use our judgment to switch in or out some papers if we feel certain topics or projects are over or under represented. And we will try to make sure there is a suitable mix of introductory and advanced topics, etc. We've discussed selection criteria on the committee and feel there are too many variables to be able document anything very meaningful - it basically comes down to the judgment of the committee, who represent a wide range of experience and backgrounds. In previous years the poll results haven't been published, just the final list of papers accepted by the committee, and this is our plan for this year also. It's already a very difficult and time consuming task for the committee to select (approximately) 120 papers from 300 very strong submissions, even with the input from the community vote (which is something unique to FOSS4G among conferences I've been involved with). So in common with other conferences, we really can't afford to give individual feedback or get into discussions with the 180 disappointed submitters on why they weren't selected, that's just not going to be practical. I think that publishing the vote results, which are the primary factor but still just part of the evaluation, would would raise more questions than answers and make the committee's job harder than it already is. Hope this helps. Cheers, Peter.

Re: [OSGeo-Discuss] Re: [Gvsig_english] New site demonstrating the use of Free Open Source Software
Simon, I'm also watching your progress with interest, and hope that we can align your work and the OSGeo-Live material. On the point of datasets, I'm open to incorporating a fine grained dataset on OSGeo-Live, if it is going to be valuable to a number of projects, and is suitably compact to fit on the OSGeo-Live DVD.

I hope that now we have some data at a finer resolution we will see some other tutorials demonstrating techniques typically done on a day to day basis. If it helps; for the next release of uDig I was going to switch to the natural earth dataset in order to better fit with OSGeo live; and be more generally interesting for a world wide audience. This sounds good but as stated most users work at a regional level not continent wide level. From my standpoint it is annoying having any number of projects asking for content to be written; and no procedures in place to easily accept the content that is available. The first project that sits down and defines how submit word, pdf, html, rst, odf etc... (with manual steps if needed) will have a much greater chance of success. Perhaps that project will be yours? I agree. I have resisted finalising my tutorial on 'preparing tutorials' so I can iron out any nuances before asking others to follow the same procedure. I think that after a couple of more tutorials I should be happy with the process and will publish my notes. I have also developed a few simple python routines that make those finicky things deeded to make a webpage functional, easy to do. These will be published and explained on the scripting subdomain. So far I have... 1. A reasonable HTML template (no need for contributor to change) 2. A reasonable style setup (no need for contributor to change) 3. Sound metadata model 4. Appropriate and diverse dataset to demonstrate techniques 5. Easy screen capturing procedure 6. A range of simple to use scripts to automate those few irritating tasks (gather images data and insert tags into HTML document, create/maintain navigation lists, synchronise metadata throughout website, create PDFs). Most of these are reasonably stable now, so as stated above, after a few more published tutorials I will be releasing these for others to use. -- Cameron Shorter Geospatial Director Tel: +61 (0)2 8570 5050 Mob: +61 (0)419 142 254 Think Globally, Fix Locally Geospatial Solutions enhanced with Open Standards and Open Source http://www.lisasoft.com ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
[OSGeo-Discuss] Introduction to geospatial open source event at FOSS4G
Hi all, This has already been mentioned on the FOSS4G list, but I wanted to make sure that everyone was aware that we'll be a doing a one day introduction to geospatial open source event the day before the main conference starts, in parallel with the pre-conference workshops. This will be aimed at a broad audience, but in particular at users, developers and managers involved with geospatial software / GIS who haven’t yet had significant involvement with open source. It will work equally well as a standalone event, or as a way of getting up to speed to get the most out of the full FOSS4G conference. More details at http://2011.foss4g.org/intro-details/. If you know of people who could benefit from this, please let them know! We'll be publicizing it through various channels. The event is being organized by Brian Timoney, who has previously run several similar events locally. We have several speakers lined up already, and we'll be looking over the abstracts submitted to the main conference also, and may ask some people to participate based on those. If you have suggestions or interest in participating feel free to contact Brian or myself.

That's the communities choice. My stance is simply that most people work with fine scale data, not broad scale data, and so have tailored my tutorials to demonstrate program use with what most people use. As for size, if people did not want to include the data into the DVD, albeit the individual 5x5 kilometre sets only occupy between 19 - 69 MB, you can be easily downloaded a ZIP in less than 5 minutes. -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Re: [Live-demo] Re: [OSGeo-Discuss] Re: [Gvsig_english] New site demonstrating the use of Free Open Source Software
Just to add to the discussion: For introductory material a simpler, basic data set may be more useful than the rather complex nc_spm_08, for example, here is one in GRASS format (47MB) http://grass.osgeo.org/sampledata/north_carolina/nc_basic_spm.tar.gz I have prepared this data set because I thought that it would be useful to have a set of simple data sets for different regions with standardized names of data layers so that we can use the same tutorial with data sets from different regions. So Simon, if you are going to create a data set for Australia to go with your tutorials, it would be great if you could use the same names as in our basic data set (or if you have a suggestion for a different name, please let me know - at this stage it will be easy to change it on our side). Then we can use your tutorial with our nc data set and students/users in Australia can use our tutorials with your data set. We can have this for many countries and many different software packages we just need to agree on the names for data layers. There are certain tasks that are region specific, such as the coordinate systems, but many tasks, from display to analysis, would be the same. In the nc_basic I have used the following names (I will be happy to modify whatever is needed): raster data: basins elevation elevation_shade geology lakes landuse soils vector data boundary_region/elev_points/geonames/ railroads/ streams/ boundary_state/ firestations/ hospitals/ roadsmajor/ streets/ census/ geology/points_of_interest/schools/ zipcodes/ We can provide the data set in other formats (similarly as we did for nc_spm_08) and add additional type of data such as orthos or landsat. There is a brief CLI tutorial available for GRASS with this data set but I would like to prepare some screencaptures on Getting started GRASS with wxGUI with this data during the upcoming GRASS community sprint in Prague (where I can hopefully learn everything that I might have missed about the ne GUI and we can capture its proper use). The larger data set nc_spm_08 is much more complex and goes with the GRASS book and I am also using it for my course. I plan to release some additional, applications oriented mapsets for this data set, but this all goes beyond the intro tutorials. So I very much agree with Simon that we need diversity in the data sets both in terms of scale and geographic location, but it would be useful to use standardized names to facilitate broader reuse of both the data sets and the tutorials.

Re: [Live-demo] Re: [OSGeo-Discuss] Re: [Gvsig_english] New site demonstrating the use of Free Open Source Software
Helena, Thanks for the comments. I have included some feedback regarding particular points below. On 30/04/11 11:53, Helena Mitasova wrote: I have prepared this data set because I thought that it would be useful to have a set of simple data sets for different regions with standardized names of data layers so that we can use the same tutorial with data sets from different regions.

So Simon, if you are going to create a data set for Australia to go with your tutorials, it would be great if you could use the same names as in our basic data set (or if you have a suggestion for a different name, please let me know - at this stage it will be easy to change it on our side). I have already acquired some local data. You can see what is provided at http://gis.fossworkflowguides.com/#data. Then we can use your tutorial with our nc data set and students/users in Australia can use our tutorials with your data set. We can have this for many countries and many different software packages we just need to agree on the names for data layers. I can see the logic here. Standard file names. Standard attribute names. Various formats. Various regional datasets. How do you propose to store different languages? This would intrinsically change both the file and field names. When I considered localisation and translation of my tutorials, I though that most people would just recreate the images and rejig the text accordingly - using the existing file as a predominantly completed template. There are certain tasks that are region specific, such as the coordinate systems, but many tasks, from display to analysis, would be the same. With this in mind, putting aside regional aspects, having one dataset that most people use in things like the LiveDVD provides for a consistent experience. My only issue here is the use of low resolution continent-wide data in the quickstarts and tutorials, when most people would be working at a regional or local level. Regional aspects is an interesting issue that need further consideration. Apart from distinct CRS, local files have distinct names, fields of attribute tables have distinct names, data has varying accuracy and/or currency, etcetera. These variations make working with regional datasets unique and tutorials that demonstrate the use of 'raw' files -- as you would expect to get them if you went and purchased them from a regional authority -- valuable and enlightening. With this in mind I must confess I am in two minds with trying to standardise all data. When considering creating a tutorial series I wanted to provide a resource for all people to use regardless of the country. In my mind this only required me to provide the data used to create the tutorials so others could repeat the steps -- which I did -- and ensure that colloquial terms are adequately explained. Derivative creation is another issue intrinsically bound to this issue. Apart from slight variation in text (assuming you are not translating the document) all the images need to be redone to show the local data in context. If you are going to go through all this effort changing a few names is a minor issue. The way I have handled this in my tutorials is to tag file names and other elements with unique tags. This provides the ability to substitute elements of the HTML webpage based on a simple translation table and substitution routine. In theory, it would be a simple matter stating that when using this vector file the term altitude should be replaced with elevation. My experience has show that the biggest impediment to derivative creation is the ability to disarticulate a tutorial, modify those elements that need changing and put it back together quickly -- as explained in detail on my website, this is why I fell back to HTML. Ideally, we should have a Content Management System that stored educational material at high enough resolution to manage this disarticulation quickly and efficiently; but, alas one does not exist at present and it is necessary to hobble together an alternative. So in summary, I can't see the value of modifying the current data I have to make a consistent dataset, as creation of a derivative using the North Carolina dataset will require recreation of the 30-40 images shown in a tutorial anyway, and a simple search-and-replace of a dataset name or field name would be a minor additional task. -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
