Your First Map

This tutorial takes you from an empty workspace to a styled map with inspectable data, in a few minutes. You can do all of it in the live viewer.

1. Open GeoLibre

Open viewer.geolibre.app, or launch the desktop app. You start with a basemap and an empty Layers panel.

2. Add a layer

  1. Open Add Data → Vector Layer.
  2. In the Add Vector panel, enter a vector URL. You can use the sample countries dataset:
    https://data.source.coop/giswqs/opengeos/countries.parquet
    
  3. Click Load. The countries appear on the map and a countries layer is added to the Layers panel.

Add Vector Layer panel with the sample URL ready to load

See Adding Data for every supported source.

3. Style the layer

  1. Select the countries layer in the Layers panel. The Style panel opens on the right.
  2. Adjust the Fill color, Outline color, and Fill opacity to taste.
  3. To make a choropleth, set Style type to Graduated, pick a numeric field (for example a population or GDP column), choose a Colormap, and click Apply style type.

4. Inspect the data

  1. Click Attribute table on the status bar to expand it, then select the countries layer to load its records. See Attribute Table.
  2. Sort by a column, or filter to find a feature. Selecting a row highlights it on the map.
  3. You can also turn on Identify features for the layer and click a country on the map to see its attributes in a popup.

5. Save or share

  • In the desktop app, use Project → Save to write a .geolibre.json file.
  • Anywhere, use Project → Share to upload the project and get a public link. See Sharing & Embedding.
