Once datasets are connected to your CARTO account, use Builder to add map layers and discover key insights about your location data. This guide describes how to view and work with map layers in CARTO Builder.
When opening a map in Builder for the first time, LAYERS and WIDGETS for the selected map appear. The LAYERS pane appears by default, displaying the basemap and map data layer(s) that are the backbone for rendering your visualization. The WIDGETS pane enables you to add interactive widgets for visualizing and filtering your data.
The following map displays a single layer in the LAYERS pane, which contains point geometries.
Positron Labels. You can edit the basemap source and style, or keep the default basemap.
As another example, the following image displays a map with multiple layers,
B. Note that layer
A has an analysis
A1 applied as part of the workflow for rendering the data, and the basemap was changed to Positron (labels below).
When working with layers in the LAYERS pane of Builder, the following features are available:
Click ADD to add a new layer to your map. The number of layers allowed is based on your account plan.
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 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.
When you click on a layer, the DATA, ANALYSIS, STYLE, POP-UP, and LEGEND options are available for the selected layer.
The Data View and Map View appear as icons on your map visualization when a map layer is selected. Click to switch between viewing your connected dataset as a table, or show the map view of your data. Additionally, you can access the connected dataset directly from the selected layer.
If your connected dataset was modified, the map layer indicates that a SQL query was applied.
Show or Hide a layer from your visualization by clicking the eyeball icon. All layers are displayed by default. This is helpful when you are styling multiple layers, or if you want to show or hide selected layers for your published map.
Manage the details of the layer by clicking the three vertical dots, located next to the layer name. These options enable you to manage the details of your layer in Builder. For example, you can rename or delete a selected layer.
Center map on layer refreshes your Map View by centering the map on the selected layer. You can access this option from the map layer context menu, or from the icon when the map is selected.
If an analysis workflow is applied to your data, the layer displays the analyses nodes (A1, A2, B1, B2) that are applied to your layer.
Analysis nodes act like sublayers in association with each map layer that they are applied to. You can automatically create a new layer from analysis results by clicking the analysis node (A1, B2) from the LAYERS pane, and dragging it above or below the selected layer to create a new layer.
Similarly, you can click and drag the original source of data from a map layer to create a new layer.
Analysis nodes (A1, B2) can be selected as the source for creating widgets, initiating dynamic filtering.
