CITY OF ATLANTA OFFiCE OF CITY COMPTROLLER ATLANTA 3, GEORGIA January 2, 1969 TO: Those Noted FROM: SUBJECT: CIP 1969 Update We have been instructed to give first priority to matching the CIP Master File against Fulton County's Real Property Master File. Fulton County is now reformatting their Real Property Master File and will have a reformatted file, updated through 1968, available for us by January 15, 1969. Parcel Code Number identification as used in our CIP file differs from that used by Fulton County on their Real Property Master File. The two identification methods are shown here: County PCN District Land Lot Square Unit XXX 9999 xxxx 999 City PCN 99X 999X 9999X 999X 9 = A digit only X = Either a digit or an alphabetic character This results in PCN identification as shown here: County PCN XXX9999XXXX999 City PCN 99X999X9999X999X As can be seen, not only are there differences in the characteristics of the various positions but the City PC N is a total of 16 characters whereas the County PCN is only 14 characters. The different PCN identification formats resulted from the Ci~y's having t o allow for Dekalb County I s numbering system when the CIP file was originally built . Dekalb County has since then changed to the PCN identification method used by Fulton County . PCN is the s equence i n which both t he City and County files are kep t . Since the PCN i denti f ier s are not c ompat ib ie in forma t , i t has been nece ss ary f or us t o transla te PCN fr om the County f ormat t o t he Cit y f ormat whe never we us ed data supp l ied by the County. Thi s translat i on pr oc e s s wou l d caus e the resultant file to be out of s equence and t hus requi r e a sort of the Mas t er File. The translation and sorting was done in order to preserve the ability to r un the series of CIP report programs which required for input, a PCN in the City's format .• �-2During the upcoming match of 1968 Fulton County tape s with the 19 67 CIP file, we will convert our PCN identifier on the CIP file to the County's format. This will render it impossible to continue to use existing CIP report programs without modifications and will alter the me thod of making updates to the master file. It is anticipated that the special Committee which has been appointed to study the data processing needs for planning information will define future reporting requirements. If it is necessary to run the CIP reports, they could he run with the 1967 CIP Master which will r emain unimpa'ired as a result of the conversion. Fulton County's file should be available for us to schedule processing the weekend of January 18 - 19. Distribution: Messrs: JG/bb George Berry Milton Converse Charles L.
