<p>Select a feature on the <b>Test Data</b> layer and drag the circle that appears when the cursor gets close to the selected geometry. On the <b>Real data (topology)</b> layer, editing adjacent countries that are selected preserves the topology.</p>
|
||||
<p>This example demonstrates how the modify and select interactions can be used together. Zoom in to an area of interest and select a feature for editing. Then drag points around to modify the feature. You can preserve topology by selecting multiple features before editing (<code>Shift</code>+click to select multiple features).</p>
