What I've seen so far looks quite encouraging. However, using a lowend machine (CPU: Cyrix 6x86L, 150 MHz, 128MB RAM running with Debian testing), Thuban massively uses up system ressources. Start-up takes CPU usage to over 75%, generating classifications as well. Loading a shapefile with only 11 polygons takes CPU usage way over 50% and any action within Thuban keeps the rate between 50 and 75%, sometimes pushing it even higher. Memory usage is around 15%. Does this mean that Thuban is only meant for higer-end machines (I will test it on a much better machine next week) ? Is there anything planned in terms of streamlining Thuban ?

It is currently primarily a viewer. Thuban intends to interconnect with various other Free GIS Software (so far gdal, shapelib and proj). It might be interesting to connect Thuban to real GIS like GRASS. In order to support the connectivity, Thuban is designed to be very flexible, eg. extensible with modules.

We did not test it on such a machine, yet and Thuban is also not optimised for speed so far. I'be been running Thunban on a Pentium II 200Mhz also with 120MB booting from a Free Software Knoppix-CD and it was a bit slow, but usable. > For example: when I open Thuban, without any maps loaded, yet, and I then > just move my mouse pointer back and forth over the Thuban screen, CPU > usage goes up to over 90%.

Here's the About dialog (I don't know about the GDAL - not available message, I installed the unofficial Debian packages of GDAL as available from the Thuban download page.): Thuban Release Version 0.8.1 Currently using: wxPython 2.4.0.7 Python 2.2.2 PySQLite 0.4.3 SQLite 2.8.2 GDAL - not available Compiled against: GTK 1.2.10 proj 4.4.7 I've been testing this config on a better machine today (Intel(R) Pentium(R) 4 CPU 1.80GHz, and 512MB RAM), and obviously Thuban is much faster and quite usable. However, I still get high CPU usage (up to over 60%) by just moving the mouse back and forth over an empty session. Memory usage stays quite low (less than 5%, even when playing around with a > 20.000 polygon shape file), but I'll check that with my old machine when I have the time.

I'm not sure either. The best would probably be to allow the user to chose a color to apply to all boundaries.

So, here I go: 1) When using the 'identify' mode, I have to click on the boundaries of my polygons to select a polygon. This is not very practical, as most of the boundaries are shared, and so I don't know which of the two polygons will be selected. Would it be possible to create a selection where the user has to click inside the area and not on the boundary ? 2) I don't really understand the projection management, yet ? Is it possible to re-project data ? I've tried doing so, but I only get empty screens. What really confuses me is that I have shpae files that (should) use the Belgian Datum 1972, but when I load them and then click on projection for that layer, the only one that works is . All the others giving me empty screens, including the Belgian Datum. Could you enlighten me on how projections work in Thuban ?

When you load a layer you must select the projection that that layer's data is in (Layer->Projection). You must then select which Projection the map is in (Map->Projection). This can be whatever you like allowing you to reproject the layers. If the only layer projection that is working is then perhaps the data in the shapefile is not what you think. Is it something you could send to me so I can see what is going on? --jonathan -- ====================================================================== Jonathan Coles jonathan at intevation.de Intevation GmbH http://www.intevation.de ====================================================================== -------------- next part -------------- A non-text attachment was scrubbed...

If the polygons are not filled only a click on the boundary will work. One reason it's done this way is that thuban searches through all layers and if unfilled polygons could be selected by clicking inside of them shapes in the layers beneath couldn't be selected with the identify tool. There probably should be a way to tell Thuban to only select shapes in one specific layer in which case Thuban could also allow the selection of unfilled polygons by clicking somewhere inside of them. Come to think of it, now that we have classifications the way Thuban determines whether the polygons are filled is not really correct anymore. IIRC it only looks at the default classification and thus may assume that the polygons are not filled even when most or all of them actually are. This ought to be fixed in some way.

I don't find this very intuitive, but as long as it will be documented, I guess it's alright. I can confirm, BTW that using a classification, I have to change the default fill color to be able to select any of the polygons, even those filled by the classification. > >> >> 2) I don't really understand the projection management, yet ?

In the attachment you will find a set of files and a patch against what was the June 20th CVS. They provide the beginnings of a custom classifier. Let me elaborate. The patch adds a "Custom breaks" option to the class generator. When selected, it opens a graphical display of the selected field that includes: a histogram (a slider controls the number of bins used), a "pointgram" (a point, or rather a vertical bar for each data value) and a set of triangular markers indicating breaks. These markers can be deleted (double-click) and added (single-click on a new location). They represent cut points from which a set of ranges will be generated. It's visually awful, and lacks useful tricks like value display, a grid-like positioning method and true sliding capabilities for the markers, but it gives good visual clues for manual classification of field values. Let me know if it's worth enhancing. In coding it, I found several ways in which it might become a permanent display for the other classifiers, as a visual guide, but that would require severe tweaking with the classification infrastructure.

The feature itself does not turn out to be more complex than expected - it is just that the development team was quite busy giving presentations on Thuban in France, Belgium and Germany in the past weeks. Furthermore, I've added italian to the aimed languages for 1.0. A first translation will soon go into CVS. Now we have german, french, spanish and itlian on the roadmap.

It looks promising (there are currently some flaws in it). We would like to incorporate it into Thuban, but don't have the time to stabilize this feature on our own for 1.0. If your time permits, it would be great if you could work on this feature. We would incorporate it into the CVS for this purpose. Then you can produce diff's against the CVS version which would make it easier for us to incorporate updates. (BTW: diff -u or diff -c would be nicer than just a diff). Furthermore, for adding your contribution to Thuban, we need your expression of intend of transferring the copyright to us or to the Free Software Foundation Europe (FSFE) or to other organization dedicated to Free (GIS) Software via the Fiduciary License Agreement (FLA). If you send this expression of intend with a GnuPG-signed E-Mail it should be OK for now. A FLA can be done later. We ask for this procedure for any major contribution to ensure legal maintainebility of the codebase. We plan to transfer Thuban via FLA to Free Software Foundation Europe anyway :-) It might take a couple of month though.

Here's the gist of what I'd love to be able to do, and any pointers much appreciated. Some open source projects have maps of developers locations, this is what I'm shooting for. I'd love to start with a map of the earth and/or US that looks something like this: http://www.fourmilab.ch/cgi-bin/uncgi/Earth/action?opt=-p&img=learth.evi f Then I would like to plot a series of points on this map, using a command line driven program under Linux. These points would likely be defined by lat/long coordinates. Finally, I'd like to convert addresses into lat/long coordinates. The challenges I haven't gotten a clear answer to are: Is there a good, freely available database that can convert locations (zip/postal codes for example) into Lat/Long for the US, or the US + other locations? Is there a good image of the US / World in the manner of the living earth image above that is freely available? I was thinking of using thuban for plotting the locations on the image, but if there is some other standard that is good at handling things in a batch manner (ie, no GUI) happy to hear of it. Thanks in advance for any pointers to what I know must be some very basic questions!

Probably comp.infosystems.gis or the FreeGIS.org mailinglist are better places to ask. The latter only if you want to do it with Free Software. :) > Some open source projects have maps of developers locations, this is > what I'm shooting for. > > I'd love to start with a map of the earth and/or US that looks something > like this: > http://www.fourmilab.ch/cgi-bin/uncgi/Earth/action?opt=-p&img=learth.evi > f > > Then I would like to plot a series of points on this map, using a > command line driven program under Linux.

That you can do nicely with GMT. http://freegis.org/details.en.html?name=The%20Generic%20Mapping%20Tools It can use a raster background image or even included nice world wide coat lines which are sufficient to make a world background map. Its documentation examples probably guides you through. > Finally, I'd like to convert addresses into lat/long coordinates. > > The challenges I haven't gotten a clear answer to are: > > Is there a good, freely available database that can convert locations > (zip/postal codes for example) into Lat/Long for the US, or the US + > other locations? For the US you might eventually get one based on census data, but for most countries of the world the answer is no. > Is there a good image of the US / World in the manner of the living > earth image above that is freely available? Yes and several resources to create those.

Thuban is geared toward interactive use, so the other mentioned applications probably are more suited to your task.

As the download page says, Thuban needs Python 2.2.1. In 2.2 the translation function does not have the fallback parameter which Thuban uses. Another reason Thuban requires 2.2.1 is that that's the oldest release that has the True and False builtins which are used in Thuban in some places. Later 2.2.x releases should also work. I'm not sure about the brand new 2.3 but there were some problems when I tried Thuban with one of the betas.
