These functions are used for finding the H3 index containing coordinates, and for finding the center and boundary of H3 indexes.
H3Index Api.GeoToH3(GeoCoord g, int r)Find the H3 index of the resolution res cell containing the lat/lng
| Name | Type | Description |
|---|---|---|
| g | H3Lib.GeoCoord | Geographical coordinate (in radians) data type |
| r | int | Resolution (0-15 inclusive) of resulting H3Index |
void Api.H3ToGeo(H3Index h3, out GeoCoord g) Find the lat/lon center point g of the cell h3
Note: This is provided to map the same general syntax of the C library. You will probably want to use the ToGeo method for H3Index data types.
| Name | Type | Description |
|---|---|---|
| h3 | H3Lib.H3Index | The H3Index cell to find the centroid of |
| g | out H3Lib.GeoCoord | The geographical coordinate that is the center of the cell |
void Api.H3ToGeoBoundary(H3Index h3, out GeoBoundary gb)Gives the cell boundary in lat/lon coordinates for the cell h3
Note: Similar to H3ToGeo in regards to C API mapping, and an assigned variable. The preferred method would be ToGeoBoundary().
| Name | Tyoe | Description |
|---|---|---|
| h3 | H3Lib.H3Index | The H3Index to find the GeoBoundary of |
| g | out H3Lib.GeoBoundary | The GeoBoundary defining the vertices of the H3Index cell |
