Betreff: Re: [Mapbender-users] Help using wfs download ...

hello charles,


what kind of download do you need? we have different modules to allow a download of data via wfs. the normal way is the wfs gazetter module, which is documented and can be seen in some of the standard guis (gui2 and gui digitize). another module, which can be seen as wfs - 'download' module was made for geoportal.rlp and is also part of mapbender. the third possibility is to use 'standardized' way of the European SDI project INSPIRE. In this SDI the access of data is managed thru 'download services' which may be feeded by wfs, wms or simple direct links. To see how this work, please have a look at http://www.geoportal.rlp.de/portal/en/information/inspire-katalog.html. 

This can be seen as a good example for the implementation of the European SDI. 

E.g. the download of protected sites (a special theme of the INSPIRE) can be achieved on the follwing page:
http://www.geoportal.rlp.de/mapbender/plugins/mb_downloadFeedClient.php?url=http%3A%2F%2Fwww.geoportal.rlp.de%2Fmapbender%2Fphp%2Fmod_inspireDownloadFeed.php%3Fid%3De9d22d13-e045-f0e0-25cc-1f146d681216%26type%3DSERVICE%26generateFrom%3Dwfs%26wfsid%3D216

In the backend we use simple wfs 1.1.0 which are registrated in mapbender. If you will a list of download options for a single metadata record there are some good webservices:
http://www.geoportal.rlp.de/mapbender/php/mod_getDownloadOptions.php?id=545eb1fe-9dee-502a-97a8-c932388a54d7

Actually mapbender is the only catalogue software which is able to allow such things ;-).

But this is a way of interoperable implementation. If you only need a good way to download data via a simple wfs client, we have implemented a download client, which is automatically generated when you fill out the relevant columns in your wfs-conf. I think, that the wfs_gazetter client is also able to handle this, but only in the current trunk version (coming 2.7.4). In 2.7.3 you have to use the wfs_tree module as we use it in our geoportal. there you have a tree representation of the different wfs-configurations (similar to the layer tree). If you wan't the sql, please ask me again.

the wfs-confs which are apriori in the wfs-conf tree, has to be defined as element var of the current mapframe. you can add more wfs-conf modules via a simple get interface to load them dynamically via catalogue search. 

maybe a complete implementation of our portal is an alternative for you? 

you can download it here:
http://www.geoportal.rlp.de/redmine/news/6

It is a virtual machine based in debian squeeze, with typo3 as a cms and mapbender_trunk as catalogue/viewer/user management engine.

with this vm it may be easier to test all things, cause there are all configs already done for productive use (geoserver/geonetwork/mapserver are implemented also)

but the download size is 9.5GB :-( .

greetings from germany

wfs conf tree:
INSERT INTO gui_element(fkey_gui_id, e_id, e_pos, e_public, e_comment, e_title, e_element, e_src, e_attributes, e_left, e_top, e_width, e_height, e_z_index, e_more_styles, e_content, e_closetag, e_js_file, e_mb_mod, e_target, e_requires, e_url) VALUES('Geoportal-RLP','wfsConfTree',1,1,'','Search- and download modules','ul','','',10,400,1,1,NULL ,'','','ul','../plugins/wfsConfTree.js','','mapframe1','','');
INSERT INTO gui_element_vars(fkey_gui_id, fkey_e_id, var_name, var_value, context, var_type) VALUES('Geoportal-RLP', 'wfsConfTree', 'wfs_spatial_request_conf_filename', 'wfs_default.conf', '' ,'php_var');


you need also the resultList modules: resultList, resultList_Highlight, resultList_DetailPopup, resultList_Zoom, the element var of mapframe is wfsConfIdString as in the gazetteer module.
