Why are the symbols of the signs on the ground given differently on two different charts of the same AIP? As can be seen in the images below, the ground markings in the same region on the airport chart and parking chart are different. Runway/Runway Approach Holding Position Marking, which includes 2 straight and 2 dash lines, is used on the Airport chart. On the Parking chart, Non-Movement Area Boundary Marking, which includes 1 flat and 1 dash line, is used. Why are different sign symbols used and how can I find out what the real signs are used on the airport surface?
Names of airport chart and parking chart in TURKEY AIP, respectively: "AD 2 LTAF ADC" and "AD 2 LTAF PRKG-1"
