Once your datasets are connected to your map, as explained in this guide, you can use Builder to discover key insights about your location data. This guide describes how to view and work with map layers in the CARTO 3 Builder.

When opening a map, layers for the selected map appear. The layers list appears by default, displaying the basemap and map data layer(s) that are the backbone for rendering your visualization.

Map layers

When working with layers in the layer list of Builder, the following features are available:

  • Layers label: Layers are created alphabetically (A, B, C, D) and each layer displays a unique color. Each layer icon displays the geometry type behind the data as either point, line, polygon, or empty.

  • Layers order: Layers are rendered from bottom to top, with basemaps being the bottom layer. Click and drag a layer to rearrange the hierarchal order of how layers are rendered on your map.

  • Layer settings: To apply custom styling to your layer.

  • Blend layers: by selecting an option from the dropdown at the bottom of the Layers panel. There are three different ways to blend layers: Normal, Additive, and Subtractive.

This guide describes how to add interactive widgets to view your map data in CARTO 3 Builder. Widgets are embedded within your visualization and do not modify your original data, they simply allow you to explore your map by selecting targeted filters of interest.

In the Wiget tab of Builder, you will see the list of your current widgets. If you haven’t created a widget yet, you will see the following page:

The tooltip is an info window that appears when you hover your mouse over a map feature. A tooltip appears where the mouse cursor is located on the map. You can customize the content of the tooltip by defining the source columns and the formatting.

It shows the coordinates where you click with the mouse. The coordinates will appear in the tooltip, so you need to activate the tooltip first.

Basemaps are image tiles that are used to render the graphical representation of your map background. Basemaps include the natural and cultural features of the world; such as water bodies, topography, park areas, terrains, roads, streets, and sometimes buildings.

The CARTO 3 Builder provides a set of CARTO and Google Maps basemaps styles as background maps. By default, basemaps are projected using the Webmercator projection. To setup your map’s base map, open the Base Map panel to select from a list of default map styles.

Select the CARTO Basemap menu to see different basemap options. They include:

  • Voyager: basemap with colors to clearly differentiate natural and cultural features. This basemap is showed by default when creating a new map.
  • Positron: light basemap with dark-colored text.
  • Dark: dark basemap with light-colored text.

Select the Google Maps Basemap menu to see different basemap options. They include:

  • Roadmap: displays the default road map view.
  • Satellite: displays Google Earth satellite images.
  • Hybrid: displays a mixture of normal and satellite views.
  • Terrain: displays a physical map based on terrain information.

Basemap layers: You can manage basemaps layers to hide and show water, buildings, roads, and more. Options include:

  • Labels: shows labels for cities, neighborhoods, and so on.
  • Roads: displays a translucent layer of road lines.
  • Borders: shows state and continent borders.
  • Buildings: shows building footprints.
  • Water: displays bodies of water.
  • Land: Shows parks, mountains, and other landscape features.
