|
'''<indexterm><primary>within</primary></indexterm>'''
|
|
Checks if the first geometry is completely inside the second geometry using the specified strategy.
|
|
|
|
[heading Description]
|
|
The free function within checks if the first geometry is completely inside the second geometry, using the specified strategy. Reasons to specify a strategy include: use another coordinate system for calculations; construct the strategy beforehand (e.g. with the radius of the Earth); select a strategy when there are more than one available for a calculation.
