Attribute Table¶
The Attribute table shows the records of the selected vector or DuckDB layer. Open it from Layer actions → Open attribute table, or expand it from the Attribute table button on the status bar and then select a layer in the Layers panel.
The toolbar¶
| Button | What it does |
|---|---|
| Edit / Save | Turn on inline editing, then write the changes back to the layer. See Editing values. |
| Explore | Open the Column explorer. |
| Statistics | Summary statistics for one field. See Field statistics. |
| Charts | Chart one or two fields without leaving the table. See Charts. |
| Dashboard | Open the Dashboard with this layer preselected, to build a persistent panel of widgets. |
| Export | Write the records you are viewing to a file. See Exporting. |
| Search attributes… | Filter rows to those matching the text you type, across every field. |
| Zoom to selection | Keep the map framed on the selected features as the selection changes. |
| Show All Features / Show Selected | Show every record, or only the selected ones. The count updates with the selection. |
The bar along the bottom reports the record count and how many are selected.
Reading and navigating¶
- Sort by clicking a column header to order rows ascending or descending.
- Resize columns by dragging their borders, and scroll horizontally when a layer has many fields.
- Resize the panel by dragging its top edge, which is worth doing before working through a long table.
Linking to the map¶
The attribute table and the map stay in sync:
- Selecting a row highlights the corresponding feature on the map.
- Zoom to selection keeps the map framed on what is selected.
- Selections support multiple features at once, and the same selection drives Edit → Export Selected Features as Layer and the selection tools.
Column explorer¶
Explore profiles every field in the layer at once: its type, how many records are populated, how many are null, how many distinct values it holds, and the shape of its distribution — a ranked bar chart of the commonest values for text fields, a histogram with min, mean, and max for numeric ones. Filter the field list by name when a layer has many columns.
It is the fastest way to answer "what is actually in this data?" before styling or filtering it — a field that is 90% null, or a "numeric" field with one non-numeric outlier, shows up immediately.
Field statistics¶
Statistics summarizes one field at a time. Every field reports Count, Nulls, and Unique; a numeric field adds Min, Max, Mean, Median, Std dev, and Sum, while a text field lists its most frequent values with their counts. Copy puts the whole summary on the clipboard.
Charts¶
Charts plots the current layer without adding anything to the project: pick a chart type (histogram, scatter, bar, line, box plot, or pie), the field or fields to plot, and any type-specific options such as the bin count. Download saves the chart as an image.
Charts here are throwaway views. For charts that are saved with the project and cross-filter each other, build them in the Dashboard instead.
Editing values¶
For editable layers (including GeoJSON layers and materialized DuckDB layers), click Edit to change attribute values inline, then Save to commit them. Combine this with the GeoEditor plugin to edit both geometry and attributes. See Managing Layers.
DuckDB layers¶
Layers produced by the SQL Workspace or added from a DuckDB source behave like vector layers here, with full identify, selection, and attribute table support. You can keep several DuckDB query-result layers open at once.
Exporting¶
You can export the records you are viewing as GeoJSON, GeoParquet, GeoPackage, a zipped Shapefile, or CSV (attributes only). The same formats are available from a layer's Layer actions → Export submenu in the Layers panel, which adds KML and KMZ. Exporting to Shapefile surfaces a warning when field names exceed the format's 10-character limit. The SQL Workspace additionally exports query results as CSV or GeoParquet, and the Conversion tools write cloud-native formats.
