GeoJSON Quick Reference with Custom Implementation

Standard GeoJSON Structure

A GeoJSON object consists of the following components:

1. type: The type of the GeoJSON object.
2. geometry: The geometric object with its type and coordinates.
3. properties: A JSON object containing additional information about the geographic feature.

Custom Parameters

MyRadar's specific GeoJSON implementation supports the following additional properties to help style the shapes:

1. color: A hex code in the form of AARRGGBB that controls the alpha and color of the shape.
2. strokeWidth: A width in points for the shape's drawn outline.
3. details_title: A short text title that gets shown when the object is clicked on.
4. details_subtitle: A subtitle for the text that gets shown when the object is clicked on.
5. details_description: A long-form text description that displays in the panel when the object is clicked on.
6. tectonic_hoverable: true/false - Sets the ability to display a short text when the mouse is hovered over the shape.
7. display_label: A text string that gets displayed if the mouse hovers over the shape (and the shape is tagged as hoverable).
8. tectonic_tappable: true/false - Sets the ability to click on the shape to bring up an additional details panel.
9. title: A text string indicating the title of the shape, displayed to a user in a details panel.
10. description: A text string providing extended details of the object.
11. details_url: An optional URL to call if this item is clicked on.

Example GeoJSON Object with Custom Parameters

    "features": [
        {
          "type": "Feature",
          "geometry": {
            "type": "Polygon",
            "coordinates": [
              [
                [-84.20, 33.50],
                [-83.80, 33.50],
                [-83.80, 34.00],
                [-84.20, 34.00],
                [-84.20, 33.50]
              ]
            ]
          },
          "properties": {
            "name": "Example Polygon",
            "category": "Region",
            "color": "80FFAABB",
            "strokeWidth": 3,
            "details_title": "Sample Area in Georgia",
            "details_subtitle": "A sample region in the state of Georgia",
            "details_description": "This is a longform text description.\n\n 
Using C-like line breaks, you can put blank lines in between sections.",
            "tectonic_hoverable": true,
            "display_label": "Sample Georgia Region",
            "tectonic_tapable": true,
            "title": "Sample Georgia Region",
            "description": "This is a sample polygon representing a region
within the state of Georgia, covering several hundred square miles.",
            "details_url": "https://example.com/region-details",
            "object_type" : "custom_data_overlay",
            "tectonic_tappable": true
          }
        }
    ]
}

In the above example, custom parameters color, strokeWidth, details_title, details_subtitle, tectonic_hoverable, display_label, tectonic_tapable, title, description, and details_url are added to the properties object of the GeoJSON feature.
