It is time for me to start data mining a data base.
I have table with 4 fields east(float8), north(float8),
elevation(float8) and memo (varchar). As you can tell this is a GIS
data. The memo field consists of descriptions transcribed from a map.
Now these descriptions were written over a peroid of 40-50 years by
various authors. So spelling has changed (complete words and
abbreviations) and english to spanish.
I want to scan throught this memo field and make a unique word list and
drop it into a new table. Then I can see exactly what words they used
and can start to filter and re-organized it into something usefull and
turn it into a thematic map.
Any suggestions where to begin?
