sample dataset including plug-ins (= was: Re: [Qgis-user] Announcing Time Manager Plugin v 0.1)
Hello, I start another thread, based on the discussion about time manager dataset. Noli Sicad claviota: Very good point. Probably you can have 2 versions with data and without data. I suggest that probably you can put a link, a button to get the sample data in one of the plugin widgets. These are all suggestions to improve usabilities of the qgis plugins in general. Yes, I plussoie beaucoup. I agree, in a more proper language. Some of QGIS plugins are hard to figure out if you don't have a properly data to work on. And most of the users, have no real use of the plugin at the time the plugin is announced and just like to see how it works. Yes. And this is particularly true in GIS software. If you look at R, for instance, they provide datasets that can be accessed so simply. It is excellent, because you are able to *really* play with data in a matter of seconds, literally. For instance, in R, all you have to do is: contour(10 * (1:nrow(2 * volcano)), 10 * (1:ncol(2 * volcano)), 1.5 * volcano, pretty(range(volcano))) To get, in ONE line, a contour map from a volcano in New Zealand. Similarly, to get a perspective view of the same data: persp(10 * (1:nrow(2 * volcano)), 10 * (1:ncol(2 * volcano)), 1.5 * volcano, theta = 140, phi = 30, scale = FALSE, axes = FALSE, shade = 0.5, border = NA) In fact, the variable 'volcano' seems to directly contain a whole dataset. No need to do any file/open or anything. Another example with another dataset provided with R, 'iris': pairs(iris[1:4], main=Edgar Anderson's Iris Data, pch=21,bg = c(red, green3, blue)[unclass(iris$Species)]) In my humble opinion, this solution is extremely effective, from the end-user-beginner point of view. Now, back to qgis: there is already the Alaska dataset, also the grass spearfish dataset. I would be in favour of compiling a state-of-the-art complete dataset, so that users can play immediately with it, and get a good feeling about softwares. Not only plug-ins, but the whole thing. This could be a sort of standard, a base on which any GIS newbie could rely on to make his own dataset: just erase all example data, and fill with your own, and you're up and running. Such a dataset has, of course, to be free (freedom), it may have data such as: - an srtm dem, - a topo map, - gpx data, - satellite imagery - a scanned geological map (sorry, je prêche pour ma paroisse = if someone knows the English translation, go on and translate ;) ), - a scanned pedological map, - a set of pictures taken from the ground, geotagged, - buildings as vectors, - roads as vectors, - field occupation (occupation du sol, in French: not sure about translation) as vectors, - a postgis database, - an sqlite database, - a mysql (forgot about postgis equivalent, sorry) database, - a whole grass dataset, - etc, etc. (unlimited) Then, any plug-in developer should add to this dataset some sample data. I think such a sample dataset should be: - well-structured (state of the art = so that the GIS newbies can inherit from the experience/errors from senior users), - small, in terms of size: this way, when a user tries some features, it doesn't run for hours or colonize the whole user's RAM, - available separately from the software itself (regarding issues mentioned during the initial discussion); if it was for instance a linux package, it could be something like qgis-sample-data. The spearfish dataset could well be a base for such an exercise. Or Alaska. Or anything else. There was a Doncaster totally fake dataset, provided with GDM (geological package): it was invented, by mixing different data from various places, mangling data. I hope if it will be in python plugin repository soon. I just like to try it. If such a solution was adopted, then every plugin developer should add relevant data in the sample data set.

Re: [Qgis-user] offline googlemaps (or the like) images
if you get your own imagery you can easily install a wms server on your machine and connect to it with qgis. I don't think WMS can do offline. This is the weakness of web mapping services, if I am not mistaken, it piggyback on TC/IP protocol (i.e without Internet connection is the services useless). I have looking at offline mapping for a while now. GMapCatcher[1] is solution since it has offline download feature. It can download from CloudMade, OpenStreetMap, Yahoo Maps, Google Map and use the download tile maps offline Now, the question is how can use the data for Qgis google layers plugin? Vincent, you can probably figure this out - Hack the qgis google layers plugin python code. BTW, it has options to save data in files or in Sqlite3 as well. Anybody interested on hacking qmapper data for Qgis? I think will provide offline mapping solution for QGIS Noli [1] http://code.google.com/p/gmapcatcher/ GMapCatcher is an offline maps viewer. It downloads tiles automatically from many providers such as: CloudMade, OpenStreetMap, Yahoo Maps, Google Map. It displays them using a custom GUI. User can view the maps while offline. GMapCatcher doesn't depend on google-map's java scripts so it should work even if google changes them. It alsg provides a downloading tool. GMapCatcher is written in Python 2.6, can run on Linux, Windows and Mac OSX. http://code.google.com/p/gmapcatcher/downloads/list ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: sample dataset including plug-ins (= was: Re: [Qgis-user] Announcing Time Manager Plugin v 0.1)
This is a great suggestion. I've used GRASS old spearfish dataset while trying to learn GRASS in the past. Additional points for discussion: - application domain - QGIS is a general purpose tool. A biologist, a geologist, a local government or a small community would have very different data requirements. A generic dataset cannot cater to all. Probably good to create multiple datasets and allow each group to curate each dataset. - geographic location - during my beginner gis courses, I find that participants appreciate the concepts if they work on a local dataset. A good resource is openstreetmap. For cartography related plugins and exercises, I suggest you use the Natural Earth dataset. 2010/10/4 Pierre Chevalier Géologue pierrechevalierg...@free.fr: I would be in favour of compiling a state-of-the-art complete dataset, so that users can play immediately with it, and get a good feeling about softwares.

Brett, I am using Linux and from a previous email I think Ken is as well. Yes, it is working on my Linux system. I tried installing QGIS onto a Windows 7 system using both the Standalone and OsGeo installers. In both cases I couldn't get it to work correctly. The standalone installer version placed AGD66 and GDA94 versions of my test point 11m apart when it should be more like 200m. The OsGeo version just refused to display the AGD66 point. I am not sure where to go with it on Windows. I haven't used it for a long time. Maybe someone more familiar with the Windows setup can help.

Regardless, I think we are on the way to solving this. Please find a new srs.db here http://dl.dropbox.com/u/9546967/srs.db. The new file incorporates both towgs84 parameters and a reference to the distortion files. The distortion file values appear to take precedence, but I have included the towgs84 parameters as it looks like the AGD84 distortion files do not cover the states and territories that did not adopt AGD84. Note that I have changed the AGD66 towgs84 parameters to national ones (previously ACT) according to this document (page 31) http://www.icsm.gov.au/gda/gdatm/gdav2.3.pdf. To use the distortion files you need to place these files http://dl.dropbox.com/u/9546967/agd66.gsb http://dl.dropbox.com/u/9546967/agd84.gsb in your Proj data directory (/usr/share/proj on Linux). It is the directory containing the 'epsg' and 'proj_def.dat' files. Make sure that this is the directory your Proj installation is actually using by checking the contents of the PROJ_LIB environment variable (echo $PROJ_LIB). It may not be set, which is OK. It took me about 4 hours to figure out I had set it to an old development directory several years ago! Note that I did try it without the +wktext parameter.
