Create Lines of Sight

create Lines of Sight amongst observer and target points

Description

A tool used to create Lines of Sight amongst observer and target points. Offsets of both observer and target points are specified as fields to allow individual setting for each point. LoS are created between every observer and target point which means that if there are $n$ observer points and $m$ target ponts then there will be $n \times m$ lines-of-sight.

Tool parameters

Parameter name	Parameter type	Description
Surface	raster	surface on which the LoS are determined.
Observer points	features - points	locations of observing points.
Observer points offset	field - double	field of the layer Observer points that has data type Double. The parameter specifies vertical offset of the observer from the surface.
Target points	features - points	locations of target points.
Target points offset	field - double	field of the layer Target point that has data type Double. The parameter specifies vertical offset of the observer from the surface.
Sampling distance	numeric value	value in units specified by Surface coordinate system that determines how often the points are placed on LoS. Default value is the same as cellsize of Surface.
Output feature layer	features - lines	output layer.

Outputs

Line feature class with lines-of-sight, that has Z-dimension. Specific fields are OID_OBSERV, observ_offset, OID_TARGET and target_offset which are necessary for further analyses. The geometry store coordinates (X,Y and Z) purely from the surface without the offsets which are stored in fields.
