    109109''Added to GCI spreadsheet, but this may be outside the desired time limit.''[[BR]]
    110110''(GCI task is the first part, not the "further refinement".)''
    111  * There is an import stylesheet for .osm files: static/xslt/import/osm.xsl
    112  * This currently has hard-coded mappings between OSM admin levels & Sahana admin levels
    113   *  * http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#10_admin_level_values_for_specific_countries
    114  * A custom controller should be written
    115   * provide a UI to the user to select their country from the dropdown which pre-populates the mapping fields for manual verification/adjustment
    116   * process the results of this to pass new variables back to the stylesheet:
    117    * http://pub.nursix.org/eden/s3xrc/vita.modules.s3xrc.s3rest.S3Resource-class.html#import_xml
    118 {{{
    119 resource = s3xrc.resource("gis", "location")
    120 template = os.path.join(request.folder, resource.XSLT_PATH, "osm", "import.xsl")
    121 resource.import_xml("uploaded_filename.osm", template=template, mynewvar="xxx")
    122 }}}
    123  * The Stylesheet needs updating to act on these vars when found
    124111
    125 A nice further refinement would be to provide a UI to select a BBOX & optional filter to pull down the .osm file via [http://wiki.openstreetmap.org/wiki/XAPI XAPI]
    126  * Initially this could be manual text box entry of BBOX/filter
    127  * Then add a Map-based BBOX selection & dropdowns for the filter (which prepopulate the real dropdowns for manual verification/amendment)
     112==== Current Status ====
     113* There is an import stylesheet for .osm files: static/xslt/import/osm.xsl
     114* This currently has hard-coded mappings between OSM admin levels & Sahana admin levels
     115 * http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#10_admin_level_values_for_specific_countries
     116* There is an S3ImportPOI method to allow features to be extracted from either an uploaded .osm file or an OSM mirror:
     117 * https://github.com/flavour/eden/blob/master/modules/s3/s3gis.py#L7938
     118 * this is accessed from the 'Import from OpenStreetMap menu option in /eden/gis
    128119
     120==== Enhancements Needed ====
     121* We need to add the Sahana UUID to these features in the OSM database.
     122 * This is needed so that we can do deduplication on subsequent imports (the OSM ID is insufficient for this as it can change over time)
     123 * This means we need to read the OSM credentials (currently a deployment_setting in 000_config.py but should be made per-user) & do a REST API call to the main OSM database with the modified feature(s)
     124* We would like to be able to control which features are imported from this UI (currently this is a deployment_setting in [000_]config.py - that should become the list of avaialble options rather than the absolute list)
     125* We would like to be able to download features for a Location from main OSM database
     126 * We want to use the Polygon (falling-back to BBOX (min_lat, max_lon, etc)) to trigger a download of a suitably-filtered .osm file via the [http://wiki.openstreetmap.org/wiki/Overpass_API Overpass API]
     127* We would like to be able to download features for a Polygon
     128 * Provide a map window with a Polygon selector tool which then triggers a download of a suitably-filtered .osm file via the [http://wiki.openstreetmap.org/wiki/Overpass_API Overpass API]
