Spatial Search Boundaries

• Specify selection criteria for extracting objects via a spatial boundary.

• Developer may specify the “exactness” of the boundary test:

  • Point in boundary - only center of object tested
  • Box in boundary - box around the object is tested
  • Boundary vs. boundary - the geometry of the object is tested

extern SE_STATUS_CODE_ENUM SE_CreateSpatialSearchBoundary

(

SE_OBJECT synth_env,

const SE_SEARCH_BOUNDS *bounds_ptr,

SE_SEARCH_BOUNDS_CLOSURE_ENUM search_bounds_closure,

SE_SEARCH_QUALITY_ENUM search_quality,

SE_INCLUSION_CHOICE_ENUM inclusion,

SE_SEARCH_DIMENSION_ENUM search_dimension,

SE_SEARCH_BOUNDARY *search_boundary_out_ptr

);

• Developer may specify whether object must be fully contained by the boundary or merely intersect it.

• Supports 3D searches for Geodetic and projected coordinate systems

• When done, free using SE_FreeGeographicSearchBoundary().
