Positions blocks¶
Position blocks allow to operate with position variables.
Note
In 1x PDI Builder, position variables are also refered to as Features.
Constant Position¶
Constant Position block defines a position on Earth using Latitude, Longitude and WGS84 Height.
Constant Position block¶
Output
Pin 0: Output of the configured position.Configuration menu:
Constant Position block configuration¶
The following parameters must be configured to define the desired absolute position:
The coordinates can be set in UTM, MGRS (Military Grid Reference System), Decimal Degrees or Degress º ‘ ”.
They are indicated through the latitude, longitude and altitude.
WGS84: The first time, the altitude must be defined with respect to the ellipsoid, WGS84. After this, MSL and AGL values will be calculated automatically and the user will also be able to define the altitude with respecto to the sea level, MSL.
Move¶
Move block outputs the position which is the result of moving the input position with the displacement of the input vector.
Move block¶
Inputs
Pin 0: Input position.
Pin 1: Input displacement vector in NED frame. It must be a vector of 3 elements, i.e. a 3x1 vector.Output
Pin 0: Output position.
Relative Vector¶
Relative Vector block calculates the relative vector in NED frame from the two input positions.
Relative Vector block¶
Inputs
From: First position. To: Second position.Output
Vector: Distance vector from the first position to the second position.
Read Feature¶
Read Feature block reads a position from a FID (feature) variable.
Read Feature block¶
Output
Pin 0: Position to read.Configuration menu:
Read Feature block configuration¶
Users must select the feature variable where the position is stored.
Write Feature¶
Write Feature block writes a position to a FID variable.
Write Feature block¶
Input
Pin 0: Position to write.Configuration menu:
Write Feature block configuration¶
Users must select the feature variable where the position is to be stored.
