Projection map – An overview
What is it for?
Use this template to make data maps with region-shading and/or points. Adapt an existing example or upload your own geographic boundary file.
How to get started
- You can either select a blueprint in the template chooser or upload your own regions in GeoJSON format.
The metadata can be used for shading regions to make a choropleth map. Additional data from a separate source (an .xlsx or CSV file) can be added using the merge option when importing data. Select "Merge with current sheet" upon importing your separate datasheet and select which column you would like to match and join your datasheets by.
Alongside regions, you can also draw points. For Points data, the template requires one row per point with at least a column for longitude and a column for latitude (both in decimal degrees). In addition, it is possible to shade points by (categorical) value and/or size points by (numeric) value. To add points to your map, switch to the Points tab within the Data tab.
- You can choose from over 40 different map projections in the "Projections" settings in the Preview tab.
- To add metadata to your popups, supply the columns with your metadata to the "Select columns to visualise" panel in the Data tab. You can also include custom content and HTML to create layouts, formatting and images.
