<\/span>Objective<\/span><\/h2>\n\n\n\n
- Use QGIS Atlas functions and a little automation.<\/li>\n<\/ul>\n\n\n\n
  \n\n\n\n
  <\/span>Use case example<\/span><\/h2>\n\n\n\n
  You have a releves_dechets layer and a beaches (or communes) layer. You want to create a report for each beach, containing :<\/p>\n\n\n\n
  \n
  The name of the beach<\/li>\n\n\n\n
  A zoomed-in map of the area<\/li>\n\n\n\n
  A PNG graphic representing the waste collected (created with Data Plotly)<\/li>\n\n\n\n
  Some dynamic statistics (sum, average…)<\/li>\n<\/ul>\n\n\n\n
  \n\n\n\n
  <\/span>Step 1: Prepare graphics for each range<\/span><\/h2>\n\n\n\n
  Use the Python script described above to generate one PNG image per range:<\/p>\n\n\n\n
  \n
  graph_Anse_Mourouk.png, graph_Pointe_Coton.png, etc.<\/li>\n\n\n\n
  Make sure the image name corresponds exactly to the value of the range field in the main layer.<\/li>\n<\/ul>\n\n\n\n
  \n\n\n\n
  <\/span>Step 2: Create the layout in the Layout Composer<\/span><\/h2>\n\n\n\n
  \n
  Go to Project > Layout > New layout<\/li>\n\n\n\n
  Add :\n
  \n
  A map frame (linked to the beach layer)<\/li>\n\n\n\n
  A dynamic text field (e.g.: [% \u00ab\u00a0beach\u00a0\u00bb %])<\/li>\n\n\n\n
  An image frame: click on the \u00ab\u00a0Add image\u00a0\u00bb icon<\/li>\n<\/ul>\n<\/li>\n\n\n\n
  Activate the Atlas :\n
  \n
  Cover object = layer (e.g. beaches)<\/li>\n\n\n\n
  Sorting (optional): you can choose a field for page order (e.g. name)<\/li>\n\n\n\n
  Filter entities with an expression (optional)<\/li>\n\n\n\n
  Automatic zoom on entity<\/li>\n<\/ul>\n<\/li>\n\n\n\n
  Click on your main map in the layout (the map to be automatically centered)<\/li>\n\n\n\n
  In the Object Properties panel, Atlas Attributes section, check :\n
  \n
  \u2705 Controlled by atlas<\/li>\n\n\n\n
  \u2705 Fit to entity<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
  \n\n\n\n
  $\"\"$ <\/a><\/figure>\n\n\n\n
  <\/span>Step 3: Dynamically insert PNG graphics<\/span><\/h2>\n\n\n\n
  In the image frame, check \u201cImage path from data\u201d<\/p>\n\n\n\n
  Then enter an expression like:<\/p>\n\n\n\n
  'file:\/\/\/C:\/temp\/export_graphiques\/graph_' || \"plage\" || '.png'<\/code><\/pre>\n\n\n\nThis will automatically display the image corresponding to each entity.<\/p>\n\n\n\n Tip: you can use replace(\u00ab\u00a0plage\u00a0\u00bb, \u2018 \u2019, \u2018_\u2019) if file names don’t have spaces.<\/p>\n\n\n\n \n\n\n\n<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n\n\n\n<\/span>Step 4: Export the atlas<\/span><\/h2>\n\n\n\n\nClick on \u201cExport Atlas as PDF\u201d ;<\/li>\n\n\n\n Choose an output folder;<\/li>\n\n\n\n Each page will contain: the map, the beach name, the graph, and associated info.<\/li>\n<\/ul>\n\n\n\n \n\n\n\n<\/span>Bonus: add dynamic statistics<\/span><\/h2>\n\n\n\nAdd text fields with QGIS expressions such as :<\/p>\n\n\n\n aggregate(\u2018releves_dechets\u2019, \u2018sum\u2019, \u201cquantite\u201d, filter := \u201cplage\u201d = attribute(@atlas_feature, \u2018plage\u2019))<\/code><\/pre>\n\n\n\nThis provides automatic totals or averages for each record.<\/p>\n\n\n\n \n\n\n\n<\/span>To summarize<\/span><\/h2>\n\n\n\nStep<\/th> Function<\/th><\/tr><\/thead> Graphics generation<\/td> With Data Plotly + Python<\/td><\/tr> Customized layout<\/td> QGIS composer<\/td><\/tr> Automatic insertion<\/td> Dynamic fields + path to PNG<\/td><\/tr> Export multi-page PDF<\/td> Atlas function<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n \n\n\n\n<\/span>Use case ideas<\/span><\/h2>\n\n\n\n\nObservation sheets by commune (fauna, flora, waste)<\/li>\n\n\n\n Environmental reports by site<\/li>\n\n\n\n Census maps + graphics<\/li>\n\n\n\n Site or project monitoring<\/li>\n<\/ul>\n\n\n\n \n\n\n\n<\/span>Coming soon\u2026<\/span><\/h2>\n\n\n\nIn the next article, we’ll go a step further and show you how to create a dynamic dashboard in QGIS itself, without leaving the GIS environment: combine Data Plotly, expressions, widgets and panels to build a real-time analysis interface.<\/p>\n\n\n\n \n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":" Having seen how to create and export a series of graphs with Data Plotly, let’s move on to the next step: integrating these graphs into a QGIS atlas or automated report.
