    **for English see below** ******************************************************************************* <br/> </br> ### Datenbeschrieb <br/> </br> Dieser Datensatz enthält die **Umrisse der 11'120 Lawinen** die aus schwarzweiss Luftbildern, welche zwischen dem 25.2.1999 und dem 1.3.1999 aufgenommen wurden, kartiert wurden. Die Lawinenumrisse haben verschiedene Attribute welche im **beigelegten Beispielschlüssel** beschrieben sind (Beispielschluessel_1999_d.pdf). Es gibt drei Shapefiles: * **avalanches1999_endversion1.shp**: die kartierten Lawinen (für Attribute siehe Beispielschlüssel!) * **area_images_1999.shp**: Fläche die durch die Luftbilder abgedeckt wurde * **clouds_1999.shp**: grobe Umrisse der Wolken in den Bildern ### Bildverfügbarkeit: Die entzerrten Luftbilder können von der [Swisstopo](https://s.geo.admin.ch/rpq3hufnb588) einzeln über den Downloadlink heruntergeladen werden (herzlichen Dank an Holger Heisig für die Prozessierung und ans BAFU für die Finanzierung der Prozessierung!!). Über "Erweiterte Werkzeuge"/ "Datei importieren" können die Bilder nach hereinziehen des Orthofotolinks direkt im map.geo.admin.ch angezeigt werden. ### Weiterführende Litertaur: Details zu den Luftbildern und zur Kartierung, sowie eine kleine Analyse und Empfehlungen zur Verwendung der Daten finden sich unter - **FAN Publikation** (Info folgt) - Dal, F.

The avalanche outlines have various attributes which are described in the **attached example key** (ExampleKey_AvalMapping_1999_e.pdf). There are three shapefiles: * **avalanches1999_endversion1.shp**: the mapped avalanches (for attributes see example key!) **area_images_1999.shp**: Area covered by the aerial images **clouds_1999.shp**: rough outlines of the clouds in the images ### Image availability: The rectified aerial images can be downloaded individually from [Swisstopo](https://s.geo.admin.ch/bg6beetinfdc) via the download link (many thanks to Holger Heisig for processing and to BAFU for financing the processing!!).
