This example uses FeatureServer to enable you to add new features to a data source, either as points, lines, or polygons, along with attribute data. You can add new features or edit existing ones, and download the layers in a variety of formats. Hover the mouse over a feature to get information about it.
Insert a new feature by choosing the appropriate tool from the toolbar, drawing the feature on the map, and filling in the attribute data below. If you wish to make your change permanent (ie survive reloading the page), save and upload your changes.
