Editing and adding features is performed within your maps.
To add or edit features in a dataset, first ensure the dataset has been added to a map.
Once you are in the map editor, zoom and pan your map to the area where you wish to add the feature, then click on a nearby feature from the same layer to open the popup window.
When using category style, ensure your new class break attribute exactly matches the existing class break values. An incorrect class break value will result in the feature not appearing on the map.
From the editing toolbar on the right of the popup, click the button to initiate the feature creation tool. Add your point, line, or polygon by clicking on map. You can fine tune the shape by clicking and dragging the corner nodes, or for point features, just click and drag the marker to your desired location.
You can only add data in the format of the dataset you are editing. ie. you can only add polygons to datasets containing polygons, points to datasets containing points.
Adding new Geometry
To add a new feature, click the button on the Data Edit toolbar to initiate the geometry drawing tool.
Drawing Points
Click on the map in your desired location to drop a marker. Drag the marker to re-position. Once your marker has been created, add your attribute data in the popup, then click SAVE to save the feature in the dataset.
Drawing Lines
Start drawing a line by clicking on the map. Continue clicking points to extend the line. Adjust the line by dragging corner or centre nodes, or delete a node by clicking on the node itself. Once you are done, add your attribute data in the popup, then click SAVE.
Drawing Polygons
Add a polygon by clicking 3 points on the map. This creates a closed polygon shape, from which you can click and drag the node handles to adjust your polygon to the desired shape. Add your attribute data in the form in the popup, then click SAVE.
Attribute Data
The form for adding attribute data will appear once you have created the geometry. It is not possible to add new attribute fields to the feature from within Mango.
