This question, I assume, is one of the dumber ones, but here goes. On parcel survey maps made in the 1960s and 1980s, they have an arrow-like symbol pointed north (specifying grid north in the more recent versions). The arrow is divided into four boxes, each with a three or four digit number. I notice that this symbol no longer appears in maps made in the 1990s. See the examples below. What did this notation mean?
Where are you located??ÿ I don't recall ever seeing such arrows on any survey, ever.
Contra Costa County, California. Zone 0403.
I??d like to see the whole sheet.?ÿ
I suspect your "dumb" question will stump most of us--I've never seen anything like that

It looks like a County GIS index back when GIS's were on paper.
Parcel numbers of adjoing tracts?
San Luis Obispo County uses an index grid with similar numbers. Ours are truncated NAD27 coords.
I agree that it is likely signifying the adjoining something (map, parcel, index, file # etc) showing the north south east and west adjoiners.
Might be unique to certain cities or counties in California
Attached are two examples of complete parcel maps and the annotated assessor's parcel map. I still can't figure out what those arrow-table notations mean.

I feel like I read that further up the thread. ?????ÿ

OK, Mr. Brilliant Smart Pants. What does the 528 represent?
Ha! You are on the wrong coast, buddy.
Seriously kidding Mr. G.

Thank you very much to you all, and especially Gary. The 528 is the Northing coordinate rounded to a kilo-foot. For small areas, the high and low values are the same when rounded to the kilo-foot.
