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
Configuration menu:
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.
Relative Vector¶
Relative Vector block calculates the relative vector in NED frame from the two input positions.
Read Feature¶
Read Feature block reads a position from a FID (feature) variable.
Write Feature¶
Write Feature block writes a position to a FID variable.
