Positions blocks¶

Position blocks allow to operate with position variables.

Note

In 1x PDI Builder, positio variables are also refered to as Features.

Constant Position¶

Constant Position block defines a position on Earth using Latitude, Longitude and WGS84 Height.

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 block outputs the position which is the result of moving the input position with the displacement of the input vector.

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 block calculates the relative vector in NED frame from the two input positions.

Inputs

Pin 0: First position.

Pin 1: Second position.
Output

Pin 0: Distance vector from the first position to the second position.

Read Feature block reads a position from a FID (feature) variable.

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 block writes a position to a FID variable.

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.
