Thuban provides a path recovery feature: If a (shape) file referenced |
511 |
|
in a Thuban session cannot be found at the specified location, the user |
512 |
|
is prompted a file dialog. Here a new location can be selected for the |
513 |
|
currents layer data source. Cancelling the dialog removes the layer |
514 |
|
from the session. If a new location has been selected, Thuban checks |
515 |
|
this again, if further layers data sources are missing. The user is |
516 |
|
informed about this and can accept or cancel the suggestion. |

Map and legend can be exported separately in the |
1713 |
|
Thuban-Map-SVG format. |
1714 |
|
You get files that comply with |
1715 |
|
the Scalable Vector Graphics (SVG) 1.1 Specification |
1716 |
|
and can be read by many vector drawing applications. |

Goal of svgexport is to provide |
1720 |
|
the start of a printing pipeline for Thuban. |
1721 |
|
For this purpose the written Thuban-Map-SVG files |
1722 |
|
contain information that can be used in postprocessing. |
1723 |
|
Typically a general vector drawing application is |
1724 |
|
more powerful then a geographic information viewer; |
1725 |
|
e.g. having much fancier symbols and fonts. |
1726 |
|
Also users benefit much more when learning to use a |
1727 |
|
more general application they can also use for other |
1728 |
|
tasks. So the charming idea is to enable |
1729 |
|
the drawing application to postprocess a Thuban maps. |
1730 |
|
So thee xtra information in the format will make it |
1731 |
|
possible to export from Thuban and if a few geoobjects |
1732 |
|
change, and keep the general layout and style |
1733 |
|
of the full map in the vector drawing appplication. |

Markus Rechtien has developed a prototype of this |
1737 |
|
printing pipline as his Diplom thetis, showing |
1738 |
|
the feasability of Bernhard Reiter's concept. |
1739 |
|
Scripts exist for the drawing application Skencil |
1740 |

(<ulink url="http://www.skencil.org"/>). |

Technical notes: the names of the layers are used |
1744 |
|
as base for ids within the SVG format. |
1745 |
|
If you try to export with two layers having |
1746 |
|
the same name, you will get a name clash error. |
1747 |
|
Just change one of the layer names and try again. |
