Table

Work with a layer's attribute data in a spreadsheet-like table that stays linked to the features on the map.

The table shows a vector layer's features as rows and its attributes as columns, like an attribute table in GIS software. The table and the map stay in step: select a row and its feature is selected on the map, and the other way around. Raster layers don't have a table.

Open the table

Click Open table in the toolbar at the top right of the map, or press T. The table opens at the bottom of the map; press T again to close it. You can also open a layer's ··· menu in the legend and click Open table. To switch layers, select another layer at the top left of the table.

People viewing the map can open a layer's table while Viewers can open table is on in the map's settings. The setting is on by default, and someone with Edit access can turn it off. See Map settings.

Find and select features

Click a row to select its feature in the table and on the map. Double-click a row to select its feature and zoom the map to it. Clicking a feature on the map selects and highlights its row in the table.

You can select only one feature at a time, in the table or on the map, so you can't select or delete several rows at once. To narrow the table to a set of features:

• Search: click the search icon at the top right of the table and enter a term to find it in any column.

• Visible: select Visible at the top of the table to list only the features in the current map view.

• Filter: in edit mode, click a column heading, select Add filter, and set a condition, such as a value the column must match. The filter becomes one of the layer's filters, so the map and the table show only the matching features for everyone viewing the map. To change or remove it, use the layer's Filter tab. See Filter layers.

To sort or summarize a column, click its heading:

• Sort: select Sort ascending or Sort descending. Sorting covers the whole table.

• Column stats: select View attribute stats. The panel shows stats such as the minimum, maximum, mean, and sum.

Edit values in the table

With Contribute or Edit access to the map, you can change a feature's values directly in the table, the way you would in a spreadsheet. See Permissions.

1. Click Edit map to enter edit mode. With Contribute access, the button says Contribute.

2. Select the row, then click the cell and enter the new value.

3. Press Enter to save it.

Edits change the layer in Felt, not the file you uploaded. To download the edited data, export the layer. See Export data.

You can't edit layers that stream tiles from another service, or the columns Felt adds to record who created a feature. Editing a latitude or longitude column doesn't move the feature; edit its geometry on the map instead. See Edit features.

To change many values at once, such as calculating a column from other columns, ask Felt AI. See AI assistant.

Add a feature or a column

To add a feature, click Add feature at the top right of the table, then place it on the map. A row appears for the feature so you can enter its values.

Adding or changing columns needs Edit access. To add, delete, rename, or reorder columns, open the ··· menu at the top right of the table and click Edit attributes. Make your changes, then click Update layer.

Change how columns appear

Changing how columns appear needs Edit access to the map. In edit mode, click a column heading, then:

• Select Rename to change the name shown in the table, labels, and popups.

• Select Format to set decimal places, a unit, or a prefix for a number column. See Number formatting.
