Coverage Contours
The Radio Coverage Contour Generator produces polygonal representations of coverage areas for a specified signal level threshold. It supports generating contours for:
- Individual radios - The coverage area for each radio is used as input for generation of polygons
- Combined radios - The coverage areas for several radios are first combined and then used as input for generation of a polygon. This can be used to create a coverage polygon for a RadioNet by selecting all radios in the RadioNet.
The workflow is the same in both cases.
Using a marching squares algorithm, the system converts rasterized coverage data into vector polygons that clearly define:
- Areas with coverage
- Areas without coverage
The polygon lines are drawn at a specified received signal level threshold for the coverage for the cells selected for the contour.
Settings
| Property | Type | Description |
|---|---|---|
| Threshold | Decibel | Defines the signal strength cutoff for what is considered “coverage.” |
| Simplify | bool | Toggles simplification that controls how detailed the polygon shapes are. |
| SimplificationTolerance | double | Polygon point tolerance used for simplification. Controls how detailed the polygon shapes are. |
| MinPolygonAreaWithCoverage | double | Minimum size for coverage areas
Note: Size is currently based on grid/pixel resolution. |
| MinPolygonAreaWithNoCoverage | double | Minimum size for no coverage areas
Note: Size is currently based on grid/pixel resolution. |
| Fill | bool | Setting for enabling fill color on the polygons |
| NoCoverageColor | Color | Display color for no coverage |
| LineThickness | double | Line thickness for the rendered polygons |
Working with Coverage Contours (API)
The API lets you generate, access, and manage coverage polygons for both:
- Individual radios
- Combined radios (combined coverage)
The workflow is the same in both cases.
General contour functions:
- Refresh All Coverage - Used when underlying radio or raidio net data changes
- Clear All Coverage - Resets the system completely
Calculating and handling contour lines are controlled via the interface IMariaRadioPlanLayer.IRadioPlanCoverageContours.
