Um diese Verhältnisse aufzuzeigen haben wir uns für einen Pixelgrid entschieden. Die Schweizerkarte am Anfang soll ein Gefühl dafür geben, wo diese Dachflächen zu verorten sind. Dafür habe ich in QGIS einen Grid aus 100 Quadratkilometer grossen Quadraten über die Schweiz gelegt und berechnet, wie viel Fläche innerhalb des jeweiligen Quadrates überbaut ist. Für den Wechsel zwischen Schweizerkarte und Pixelgrid brauchte es eine Animation. So soll aufgezeigt werden, dass es sich im Pixelgrid um genau diese Flächen aus der Schweizerkarte handelt. Dafür haben sich die D3 Transitions sehr gut angeboten. Die grösste Schwierigkeit in diesem Projekt war es , mit den unterschiedlichen Massstäben zurecht zu kommen. Durch die Legende im publizierten Stück wird dem Leser erklärt, dass ein Quadrat, welches auf der Karte 100 Quadratkilometer darstellt, im Pixelgrid nur 2 Quadratkilometer repräsentiert. In diesem Projekt konnte ich mich mit Animierten Visualisierungen auseinandersetzen. Zudem habe ich gelernt, wie man mit Rastern arbeitet und diese mit JavaScript positionieren kann. Die Daten und die Story hinter dieser Datenvisualisierung entstand in Zusammenarbeit mit Manuela Paganini und Jonas Oesch.31:T7ea,style = html``32:[{"id":"1759483b5e7acfb53c6c7020e6f8ef29b9aba47ada215af96bd719462663c4681ab982615b9fbcc8fd7f1bb5f653b96a8c3171906616fc79b6dbd2c82129f108","href":"https://static.observableusercontent.com/files/1759483b5e7acfb53c6c7020e6f8ef29b9aba47ada215af96bd719462663c4681ab982615b9fbcc8fd7f1bb5f653b96a8c3171906616fc79b6dbd2c82129f108","name":"residental_grid_merged_summiert@2.csv","type":"text/csv","lastModified":1668766074526.644,"size":6874}] 2e:{"id":"6fe188e6e137dfe7","slug":"muss-bald-jedes-dach-ein-solardach-sein","title":"Muss bald jedes Dach ein Solardach sein?","thumbnail":"8d807adf4e0a274ce048adf27b5e97908b84a327777a70b081b78fa54a3f5d84","access_level":"public","create_time":"$D2022-11-18T10:07:54.526Z","update_time":"$D2022-11-18T12:26:12.452Z","view_time":null,"first_public_time":"$D2022-11-18T10:25:25.921Z","has_unpublished_edits":null,"fork":{"id":"0362318597bde9c0","slug":"solardacher-grid-v6","title":"Solardächer Grid V6","owner":{"id":"1562866c628110c3","login":"jochem","name":"Cian Jochem"}},"stars":0,"starred":false,"owner":{"type":"team","id":"1562866c628110c3","login":"jochem","name":"Cian Jochem","avatar_url":"https://avatars-next.observableusercontent.com/67f2d078f4dd1723b0a3f99c1884e1710bc62010cd0208722f2f3376191dc6bb","tier":"starter_2024"},"version":989,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"228445908605fe2d","login":"jochem","name":"Cian Jochem","avatar_url":"https://avatars-next.observableusercontent.com/67f2d078f4dd1723b0a3f99c1884e1710bc62010cd0208722f2f3376191dc6bb","tier":null}],"members":[{"type":"individual","id":"228445908605fe2d","login":"jochem","name":"Cian Jochem","avatar_url":"https://avatars-next.observableusercontent.com/67f2d078f4dd1723b0a3f99c1884e1710bc62010cd0208722f2f3376191dc6bb","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":0,"collection":null,"type":"notebook","body":{"titling":"auto","title":"Muss bald jedes Dach ein Solardach sein?","cells":[{"id":0,"value":"# Muss bald jedes Dach ein Solardach sein?\n\n**Der Bund will Atomkraftwerke durch Solaranlagen ersetzen.
