Member Function Documentation

ConvertToLatLon()

ElevationRequest ElevationService::ConvertToLatLon ( const ElevationRequest & request )

static

Converts the coordinate locations in the given request to latitude/longitude values.

---

Parameters

[in]

request

The elevation request whose locations will be converted.

Returns

A new ElevationRequest with locations expressed in latitude/longitude coordinates.

postRequest()

virtual void ElevationService::postRequest ( const ElevationRequest & request )

pure virtual

Posts an asynchronous elevation request to the service for processing.

---

Parameters

[in]

request

The elevation request containing locations and callback information.

Implemented in GeoTiffElevationService, and OpenElevationService.

PrimaryService()

ElevationService * ElevationService::PrimaryService ( )

static

Returns the primary ElevationService instance registered for the application.

---

Returns

Pointer to the primary ElevationService, or nullptr if none has been set.

SetPrimaryService()

void ElevationService::SetPrimaryService ( ElevationService * elevation_service )

static

Sets the primary ElevationService instance for the application.

---

Parameters

[in]

elevation_service

The ElevationService to register as the primary service.

SplitRequestsIfNeeded()

Buffer< LineElevationRequest > ElevationService::SplitRequestsIfNeeded ( const Buffer< LineElevationRequest > & requests, uint04 max_samples )

static

Splits polyline elevation requests that exceed the maximum sample count into smaller sub-requests.

---

Parameters

[in]	requests	The polyline elevation requests to potentially split.
[in]	max_samples	The maximum number of samples allowed per individual request.

Returns

A buffer of LineElevationRequest objects, each within the max_samples limit.

Note

It is unclear whether the split requests are subdivided by polyline segment or by sample count redistribution across the original polyline geometry.
