![]() Hello everyone, This is to announce my first plugin for WW. It imports the data of the IGN Géoportail into WorldWind, so one can make use of the high resolution imagery on the whole French territory. It is the first version so there are still quite a few problems: - It is a bit slow - The correspondance between the scale and the level (in the Geoportail sense) is not perfect: Some high-detail-level tiles are loaded too soon, and the horizon of view is not deep enough. - Tiles at the East and South limits are not taken care of: in this case, the Geoportail service does not send the whole 384x384 tiles but a tile smaller than that. It concerns only Corsica, so it is not that bad. - Some tiles are downloaded only after multiple tries, but I am still not sure if it comes from the Geoportail service (the dreaded Unavailable Service) or from some other problem. It sometimes happens with the Geoportail website itself, but seemingly not as often as with the plugin. - The only data currently is from metropolitan France but adding other territories should not be very difficult (although finding the right projection parameters can be sometimes challenging) Anyway, apart from that, it seems to work ok :-) and I hope to solve at least some of these deficiencies this week. Note that I started programming the plugin by modifying the VE Plugin, so any resemblance with the latter is not accidental. You can download the code for the plugin there. It has been tested with WW 1.3.5 only and it should be considered highly experimental at this point... To install it, you just have to unzip it in the WW root directory: It will create a GeoportailPlugin directory inside the Plugin directory and copy the sources of the plugin there, as well as copy the proj.dll file at the WW root. Then the plugin should be compiled and initialized automatically when launching World Wind. However, you will have to load it explicitly (with Plug-Ins > Load/Unload...) from the interface in order to use it. The screenshot above is somewhere near Annecy, using the Aerial view layer. Below, is a place nearby, with the Scan layer: ![]() guilhem Last edited by guilhem; 08-26-2006 at 11:17 PM. |

Very nice.
![]() I can't get it to work, but I'm using a development build of WW and the VE plugin doesn't work either. You should grab a daily build and check it in that. |

Là, je dois dire chers compatriotes que c'est un must...S'il y a effectivement comme tu le dis de légers défauts d'affichage, je trouve ce truc aussi réussi que le plugin de Gaby avant le Géoportail... Pour les PB rencontrés, au niveau de l'install aucun, je néglige le fait d'avoir eu à le loader à la main... pour l'affichage, je l'ai essayé depuis le col des montets, entre Chamonix et Vallorcine, la ressemblance est frappante... on distingue même les dru par rapport à l'aiguille verte ce qui signifie que le modèle alti est pas mal... Un difficulté c'est que les Jorasses qui devraient être cachées passent devant les Drus pour mieux comprendre : la case à cocher terrain on c'est que tu applique aussi la donnée Alti d'IGN ?? par contre je ne comprend pas le trim cache... Je suis en attende de la prochaine version, mais c'est trop toooooooooooooop ![]()

Thanks for your comments!
Actually the Trim Cache is to delete all the cached tiles and the Terrain On is to remove the display of all the Geoportail data (currently only metr france but later all the overseas territories too). But as you have noticed, these functionalities do not work currently... This has been corrected in my dev version though. The altitude is taken from WorldWind directly. The background tiles which sometimes appear in front of the foreground tiles is a problem I have also noticed on the VE plugin, but I have not been able to resolve it yet. I agree it is pretty displeasing and correcting it should be top priority. guilhem |

Oh, i've notice a problem in viewing places high in altitude,
the best defined picture does not appair, it's only when i reduce the vertical exageration to 0 that it works... take à look at Chamonix town, near Annecy.. Oh, je me suis aperçu d'un problème quand l'on visualise des sites d'altitude, les images en meilleure définition n'apparaissent pas, c'est suelement lorsqu'on positionne l'exagération verticale sur 0 que ça marche... Jettez un coup d'oeil sur la ville de Chamonix, près d'Annecy...

Résultat très impressionnant.
Enfin ces données sont mise à leur juste valeur ! Dommage pour l'ign qui paye bonbon pour avoir un visualisateur 3d qui à avis avis sera moins bien Chapeau l'artiste ! |

Merci beaucoup pour ce plugin!!
J'attendais avec impatience un tel add-on, et je suis ravi qu'il existe enfin, et que nous puissions profiter de toutes ces données de l'IGN... A part le fait qu'il soit effectivement un peu lent, il marche très bien chez moi. Je regrette cependant que les differents niveaux de définitions ne soient pas parametrables via le fichier Config\Earth\@Images.xml, ou d'une autre manière : les "tiles" apparaissent souvent de manière désorganisées... Mais ce n'est qu'une première version, que je trouve déjà sensationnelle!! Merci encore!! |
