DS-Annotate empowers users to draw intricate polygons over aerial imagery using the Segment Anything Model (SAM)and the Magic Wand functionality. DS-Annotate simplifies the process of creating complex polygons on maps, making it an essential asset for detailed annotation.

To get started, follow these steps:

• Select the desired project and class from the sidebar menu.
• Wait until all imagery tiles are loaded in the map.

Once your workspace is set up, you can begin annotating in two ways:

• Magic Wand: Right-click on the area you want to select. You can click and drag your mouse up/down to adjust the thresold. After making your selection, press the s key to store the polygon.
• Segment Anything Model: Click on the element in the imagery you want to get mapped. Then, press the Segment Anything button to activate the model and start getting the polygons. If you want more elements mapped, just click on them.

Both ways offer precise and efficient mapping, enhancing the overall annotation experience.

You can then download the polygons in GeoJSON format or export it to the Java OpenStreetMap Editor (JOSM).
