Draw Circle on Map Esri Javascript

In Map Viewer, you can create features on a map by creating a sketch layer. A sketch layer is a type of feature collection. When you create a sketch layer, you create features to symbolize something you lot want to evidence on the map. You can also add descriptive information that appears in pop-ups when the characteristic is clicked.

Tip:

You can use keyboard shortcuts to quickly complete common workflows in Map Viewer. To view the full list of keyboard shortcuts in Map Viewer, press Alt+? on Microsoft Windows or Option+? on Mac.

The features in a sketch layer are saved with the map so that simply y'all, the map author, tin can edit and save them. Creating a sketch layer is a practiced way to add a small number of features to a map, for instance, the swimming pools managed by your city'south parks and recreation department. Sketch layers are likewise a way to create characteristic layers if you don't have an organizational account with publishing privileges or access to ArcGIS Server.

There are six types of features you can depict in a sketch layer. Choose from stamps, lines, polygons, rectangles, circles, and text.

Create a sketch layer

To create a sketch layer, complete the following steps:

1. On the Settings (lite) toolbar, click Add sketch .

   The Sketch pane appears and the sketch tools appear on the map.

Tip:

To add additional sketch layers to the map, click Add on the Contents toolbar and cull Sketch .

2. Follow the instructions for whatever of the following sketch tools to add features to the map:
   • Stamp
   • Line
   • Polygon
   • Rectangle
   • Circle
   • Text
3. Optionally, click Snapping and change the snapping options as follows:

   Snapping provides visual guides that help yous draw shapes—for example, draw at correct angles or draw straight lines—and allows you to identify features straight on the edges and vertices of features.

   • Plough off the Enable snapping toggle button to disable snapping.
   • Turn off the Geometry guides toggle button to disable the visual guides that appear when you are drawing or updating sketch features—for example, guides that assistance you draw right angles and straight lines.
   • Plough off the Feature to feature button to disable the ability to snap to the vertices and edges of other features while drawing and updating sketch features on the map.
   • If snapping is enabled, click Snapping layers and select additional layers in the map to allow snapping to features in other feature layers when drawing and updating sketch features. Click Select all to allow snapping to features in all layers in the map.

   Tip:

   Feature to feature snapping can be used with hosted feature layers and with WFS, CSV, and GeoJSON layers.

4. Optionally, add pop-ups to the sketch features.
5. Shut the Sketch pane when y'all're finished.

Add together stamps

You can use stamps to symbolize points of interest on a map. For instance, you can use special symbols to represent hospitals, evacuation points, or hiking trails.

To add a stamp, complete the following steps:

1. Create a sketch layer as described above or choose an existing sketch layer in the Layers pane.
2. From the sketch tools, choose Postage .
3. Click a point on the map where you want to place the postage stamp.

   A default postage stamp is placed on the map.

4. Use the following options, depending on the symbol, to change the appearance of the stamp:
   • Symbol—Select a symbol set from the drop-downward bill of fare, and choose a symbol from the symbol set. Optionally, click Invert groundwork color to see how the symbols appear against a night background.

     These symbols are in scalable vector graphic (SVG) format, which is a vector prototype format for second graphics. Vector symbols are simply supported in some apps, including ArcGIS Instant Apps, ArcGIS StoryMaps, and ArcGIS Field Maps. Instead of the vector symbols y'all apply to a map, a default symbol is practical when the map is used in apps that don't yet support these symbols.

   • Size—Utilise the slider to change the symbol size or change the pixel value in the text box.
   • Rotation—Utilize the slider to change the rotation of the symbol, or change the caste value in the text box.
   • Fill—Ensure that the toggle push is turned on. Select a colour from the preset options or from the custom color picker. You tin also specify a custom color using a hexadecimal value. Click Add to salve a custom color and click Remove to remove a saved color. Optionally, use the Fill transparency slider to apply transparency to the fill, or alter the transparency value in the text box.
   • Outline—Ensure that the toggle button is turned on. Select a color and outline transparency as you did for Fill up. In the Stroke section, use the slider to modify the line width, or change the pixel value in the text box.

When you lot set the style for a sketch feature, the style and pop-upward content persist for subsequently placed features of that type. Changes to the style apply to the most recently placed feature and to subsequent features.

You tin use lines to symbolize boundaries and routes.

To add a line, complete the following steps:

1. Create a sketch layer as described to a higher place or choose an existing sketch layer in the Layers pane.
2. From the sketch tools, choose Line .
3. Click a point on the map to brainstorm drawing.

   A point appears on the map and a line extends from information technology, controlled by the mouse pointer.

4. Click another point on the map to join the line to that point. Continue clicking other points on the map to add more vertices and line segments.

   If yous make a mistake while drawing, you can utilise keyboard shortcuts to undo and redo vertices.

5. Double-click or use a keyboard shortcut to identify the endpoint and complete the line.

   The line is drawn on the map.

6. Do either of the following in the Sketch pane to alter the line'southward appearance:

When you prepare the style for a sketch feature, the mode and pop-up content persist for afterward placed features of that type. Changes to the fashion use to the most recently placed feature and to subsequent features.

Add polygons

You can use polygons to symbolize irregularly shaped areas.

To add together a polygon, consummate the following steps:

1. Create a sketch layer every bit described in a higher place or choose an existing sketch layer in the Layers pane.
2. From the sketch tools, choose Polygon .
3. Click a point on the map to place a vertex. Lines are automatically drawn to bring together vertices every bit they are placed.

   If you lot make a mistake while cartoon, you can employ keyboard shortcuts to disengage and redo vertices.

4. Double-click or use a keyboard shortcut to place the final vertex and complete the polygon.

   The polygon is drawn on the map.

5. Utilise either of the following options in the Sketch pane to change the polygon'due south appearance:

When you fix the style for a sketch feature, the manner and popular-upwards content persist for subsequently placed features of that type. Changes to the way utilise to the about recently placed feature and to subsequent features.

To add a rectangle or a circle, complete the following steps:

1. Create a sketch layer as described higher up or choose an existing sketch layer in the Layers pane.
2. From the sketch tools, choose Rectangle or Circle .
3. Elevate to brainstorm cartoon a shape on the map where you want the feature to be placed.
4. Release the mouse button to complete the feature and place it on the map.
5. Optionally, do either of the post-obit in the Sketch pane to change the feature's appearance:

When you set the fashion for a sketch feature, the style and pop-up content persist for subsequently placed features of that type. Changes to the style employ to the most recently placed feature and to subsequent features.

Add text

You can use text to label or provide information about anything on the map.

To add together text, consummate the post-obit steps:
