Feature Classes in EarthRanger organize geographic elements such as points, lines, and polygons into structured groups based on real-world entities, like roads, rivers, or park boundaries. Grouping similar features (e.g., all roads or all water sources) under Feature Classes allows for precise control over their visual display, including adjustments to icons, colors, opacity, and line widths. This configuration ensures a clear distinction between map elements and enhances visualization and readability in the Map Window.
To configure how specific feature icons appear, follow these steps:
- Navigate to the EarthRanger Administration website.
- Go to Home > Map Layers > Feature Classes.
- Select the feature class you want to customize from the list.
- On the Change Feature Class page, find the Presentation section and modify the settings for the feature type (Point, Line, or Polygon).
For polygons and lines, you can adjust visual properties such as:
-
Fill Color: Sets the interior color of the polygon. Specify the color using a hex code. Example:
{"fill": "#f4d442"}. Find hex color codes here. -
Stroke Color: Defines the boundary color of the polygon or line. Enter the hex code for the desired color. Example:
{"stroke": "#000000"}. -
Opacity: Controls the transparency of the fill and stroke. Values range from
0(completely transparent) to1(fully opaque). Example:{"fill-opacity": 0.2, "stroke-opacity": 0.7}.
For points, the following settings are customizable:
-
Image: Specifies the URL of the custom icon to be used. Example:
{"image": "/static/ranger_post_black.svg"}. -
Size: Set the size of the icon in pixels. Example:
{"width": 20 and “height”: 20}.
5.Once you're done making changes, click Save to apply your customizations.
This allows you to control the appearance of each feature on the map and ensures that users can easily interpret the information about your physical locality.
Ensure the geospatial data is correctly imported and organized before proceeding with Feature Class customization.
