Detailed Description

Manages a set of ShapeBaseChart objects at different resolutions.

Maintains multiple basemap charts at varying quality levels and scales. Handles selection of the appropriate chart based on the current view scale.

Member Function Documentation

Cleanup()

void ShapeBaseChartSet::Cleanup ( )

inline

Definition at line 372 of file shapefile_basemap.h.

CrossesLand()

bool ShapeBaseChartSet::CrossesLand ( double  lat1, double  lon1, double  lat2, double  lon2  )

inline

Determines if a line segment between two geographical points crosses any land mass.

Uses the highest quality chart available for the test to get the most accurate result.

Parameters

lat1	Latitude of the first point of the line segment.
lon1	Longitude of the first point of the line segment.
lat2	Latitude of the second point of the line segment.
lon2	Longitude of the second point of the line segment.

Returns

true if the line segment crosses land according to the highest quality chart, false if no crossing is detected or if no charts are usable.

IsUsable()

bool ShapeBaseChartSet::IsUsable ( )

inline

Checks if the chart set contains at least one usable chart.

Returns

true if the chart set contains at least one chart and the lowest quality chart is usable as determined by ShapeBaseChart::IsUsable().
