Narrative:

At the new air carrier terminal in lga we called for pushback clearance and were told to push for spot 24. When we were released from the tug I began to taxi to what the first officer and I believed to be spot 24, after checking our commercial publication pages for this area. We were then informed by ground control that we had passed spot 24 and were in his control area (without a clearance). The first officer and I were unfamiliar with this new area so we both had the applicable chart out. The chart depicts white areas, that we took to mean grass or dirt surfaced areas, and used as a reference for spot 24. We discovered that this white area on the chart may mean dirt or a hard ramp area in actuality. This presentation is not defined in the commercial publication's introduction. This was compounded by a wet surface, rain and overcast that made painted lines and numbers very difficult to see. I would like to see better ramp and taxiway markings and a better chart depiction of areas that are dirt, grass, or hard surfaced ramp 'islands' that should be avoided.

Original NASA ASRS Text

Title: FLC OF ACR MLG ACFT TAXIED BEYOND CLRNC LIMIT AFTER GATE PUSH-BACK.

Narrative: AT THE NEW ACR TERMINAL IN LGA WE CALLED FOR PUSHBACK CLRNC AND WERE TOLD TO PUSH FOR SPOT 24. WHEN WE WERE RELEASED FROM THE TUG I BEGAN TO TAXI TO WHAT THE FO AND I BELIEVED TO BE SPOT 24, AFTER CHKING OUR COMMERCIAL PUBLICATION PAGES FOR THIS AREA. WE WERE THEN INFORMED BY GND CTL THAT WE HAD PASSED SPOT 24 AND WERE IN HIS CTL AREA (WITHOUT A CLRNC). THE FO AND I WERE UNFAMILIAR WITH THIS NEW AREA SO WE BOTH HAD THE APPLICABLE CHART OUT. THE CHART DEPICTS WHITE AREAS, THAT WE TOOK TO MEAN GRASS OR DIRT SURFACED AREAS, AND USED AS A REF FOR SPOT 24. WE DISCOVERED THAT THIS WHITE AREA ON THE CHART MAY MEAN DIRT OR A HARD RAMP AREA IN ACTUALITY. THIS PRESENTATION IS NOT DEFINED IN THE COMMERCIAL PUBLICATION'S INTRODUCTION. THIS WAS COMPOUNDED BY A WET SURFACE, RAIN AND OVCST THAT MADE PAINTED LINES AND NUMBERS VERY DIFFICULT TO SEE. I WOULD LIKE TO SEE BETTER RAMP AND TAXIWAY MARKINGS AND A BETTER CHART DEPICTION OF AREAS THAT ARE DIRT, GRASS, OR HARD SURFACED RAMP 'ISLANDS' THAT SHOULD BE AVOIDED.
