PCMW calculates velocity vectors by making point-to-point measurements as opposed to correlation tracking. Use the LB or LS command to properly set the loop bounds before running the PCMW command. The maximum number of frames in the loop is 10. Use keyword GLOCK to lock the current graphics frame for PCMW output.
The cursor expands and the color changes as a visual queue indicating that half of a vector measurement was made.
Units of u, v and SPD are in meters per second on the text frame and knots on the graphics frame.
PCMW
This entry computes velocity vectors using the cursor center for locations.
PCMW COLOR=2
This entry starts the local mode of PCMW and plots wind flags in graphics color level 2.
PCMW COLOR=1 GLOCK=YES SIZE=15
This entry plots 15-pixel wind flags in graphics color level 1. All wind flags are plotted on the current graphics frame.
