Changes in Thuban 1.0rc1 |
| 2 |
======================== |
| 3 |
|
| 4 |
- Redering improvements |
| 5 |
|
| 6 |
Rendering the map in the main window does not freeze Thuban |
| 7 |
completely anymore. While the rendering occurs the window is updated |
| 8 |
regularly to show the progress and you can interact with the window |
| 9 |
and thuban in general even when the rendering is not complete yet |
| 10 |
|
| 11 |
The map display is also faster in many cases now, especially when |
| 12 |
doing classifictions. |
| 13 |
|
| 14 |
The renderes have a mechanism to define how new layer classes defined |
| 15 |
in extensions can be rendered (see the new wms extension for an |
| 16 |
example) |
| 17 |
|
| 18 |
- Added a few extensions in the Extensions sub-directory. Most of them |
| 19 |
are experimental to varying extents. |
| 20 |
|
| 21 |
- gns2shp |
| 22 |
|
| 23 |
Convert GNS (GEOnet Names Server) files to shapefiles. See |
| 24 |
Extensions/gns2shp/gns2shp.py for more information |
| 25 |
|
| 26 |
- wms |
| 27 |
|
| 28 |
Use thuban as WMS client. See Extensions/wms/wms.py for more |
| 29 |
information |
| 30 |
|
| 31 |
- importAPR |
| 32 |
|
| 33 |
Import a ArcView project file (.apr) and convert it to Thuban. |
| 34 |
|
| 35 |
- profiling |
| 36 |
|
| 37 |
For developers: perfomance measurement for the rendering code. |
| 38 |
See Extensions/profiling/profiling.py for details. |
| 39 |
|
| 40 |
- drawshape |
| 41 |
|
| 42 |
This is a *very experimental* and potentially *dangerous* extension |
| 43 |
to add shapes to a shapefile. Be careful with it as it may lead to |
| 44 |
data loss. For more information, see Extensions/drawshape/README |
| 45 |
|
| 46 |
- A new command line option --enable-attribute-editing, which when |
| 47 |
given turns on editing of attribute values in the identify view. It |
| 48 |
only works on layers whose attribute data is stored in DBF files. |
| 49 |
This experimental and may lead to data loss, so be careful when using |
| 50 |
it. |
| 51 |
|
| 52 |
- EPSG projections |
| 53 |
|
| 54 |
Thuban now comes with two .proj files containing EPSG projections |
| 55 |
(epsg.proj and epsg-deprecated.proj in Resources/Projections/). These |
| 56 |
projections can be shown in the dialog with the new check boxes under |
| 57 |
"Show EPSG". |
| 58 |
|
| 59 |
- Context menu in the legend window |
| 60 |
|
| 61 |
The legend window now has a context menu for most of the layer |
| 62 |
commands |
| 63 |
|
| 64 |
- Localization updates |
| 65 |
|
| 66 |
The localization is now done with wxWindow's localization support and |
| 67 |
thus deals automatically with character encoding transformations and |
| 68 |
the standard dialogs are also translated properly if the wxWindows |
| 69 |
.mo files are installed |
| 70 |
|
| 71 |
Updated translations for French and Spanish contributed by Daniel |
| 72 |
Calvelo. Updated German translation |
| 73 |
|
| 74 |
- PostGIS improvements |
| 75 |
|
| 76 |
- Quote table and columns names properly. |
| 77 |
|
| 78 |
- The dialog deals better with duplicate connections (e.g. trying to |
| 79 |
create a new connection when there already is a connection for the |
| 80 |
same database) |
| 81 |
|
| 82 |
- Files written with the Windows version of Thuban can now be read by |
| 83 |
the unix version. The other way round was already possible. |
| 84 |
|
| 85 |
- The shapefile handling code now uses shapelib 1.2.10 |
| 86 |
|
| 87 |
- Thuban should work without problems and warnings with Python 2.3 now. |
| 88 |
|
| 89 |
|
| 90 |
Changes in Thuban 0.9 |
| 91 |
===================== |
| 92 |
|
| 93 |
- An initial version of the Thuban User's Manual. Currently only the |
| 94 |
XML sources and the images are shipped with the Thuban sources. The |
| 95 |
binary distributions do not contain the document at this point. An |
| 96 |
online version is available at |
| 97 |
http://thuban.intevation.org/documentation.html |
| 98 |
|
| 99 |
- New Translations: German, Italian and Russian. The Italian and |
| 100 |
Russion translations are based on 0.8.1 and therefore not quite up to |
| 101 |
date. German is up to date, though. For 1.0 we intend to have a |
| 102 |
translation period where all translations can be brought up to date. |
| 103 |
|
| 104 |
- PostGIS support. This feaure is still a bit experimental at this |
| 105 |
point and is not very well tested yet. It should work PostgreSQL |
| 106 |
7.2.1 and postgis 0.7 as that's what we tested it with. Newer |
| 107 |
versions probably also work. |
| 108 |
|
| 109 |
The user as which the connection is established obviously needs |
| 110 |
select permissions on any table to show and also on the |
| 111 |
geometry_columns table. |
| 112 |
|
| 113 |
Known Issues: |
| 114 |
|
| 115 |
- Only four geometry types are currently supported: POINT, |
| 116 |
MULTILINESTRING, POLYGON and MULTIPOLYGON. |
| 117 |
|
| 118 |
- Tables must have a gid column which is assumed to be a non-NULL |
| 119 |
integer which uniquely identifies the row. |
| 120 |
|
| 121 |
- It's not optimized so some things may be very slow. For instance |
| 122 |
the number of queries done could be reduced substantially |
| 123 |
especially if you use classifications. Having an index on the gid |
| 124 |
column can speed things up in that case. Note that at least older |
| 125 |
versions shp2pgsql do not create such an index. |
| 126 |
|
| 127 |
- Renamed the subdirectory extensions to libraries. The name extensions |
| 128 |
can now be used for a directory with Thuban extensions. |
| 129 |
|

More changes in even more detail are listed in the ChangeLog file. |
