Any suggestions about what is wrong with either of the versions of this dissolve command?
v.dissolve --overwrite input=alcala_subsectors@SAA2024 column=ID output=alcala_subsectors_dissolved@SAA2024 aggregate_columns=group_concat(REGION),max(STRATUM),max(SECTOR),avg(SUBSECTOR),group_concat(SECTOR_ID),sum(AREA),group_concat(SURVEYED),avg(IDNUM) result_columns="region TEXT,stratum INTEGER,sector INTEGER,subsector REAL,sector_ID TEXT,area REAL,surveyed TEXT,IDnum REAL" v.dissolve --overwrite input=alcala_subsectors@SAA2024 column=ID output=alcala_subsectors_dissolved@SAA2024 aggregate_columns=group_concat(REGION),max(STRATUM),max(SECTOR),avg(SUBSECTOR),group_concat(SECTOR_ID),sum(AREA),group_concat(SURVEYED),avg(IDNUM) result_columns="region,stratum,sector,subsector,sector_ID,area,surveyed,IDnum" I'm trying to maintain my attribute table because of the great difficulty in reconnecting it. In both cases, I get the error: Option <result_columns> requires all of <aggregate_columns> I have the same number of result columns as I do aggregate columns with equivalent data types. I have 8 columns (dissolved by the 9th column ID): region TEXT stratum INTEGER sector INTEGER subsector REAL sector_ID TEXT area REAL surveyed TEXT IDnum REAL Michael _____________________________ C.
