I am new to QGIS and GIS in general. I have a CSV file that looks like this:

FIPS Code   Area Name   Area Description
10001       A1          D1
10002       A1          D1
10003       A2          D2 
10004       A2          D2

I want to create a vector layer or shapefile that will show boundaries for each Area based of FIPS codes that belong to that Area. I do not want to see county FIPS borders, just Area borders.

I have "wkt_geom" data for each FIPS. I extracted it from Counties Vector Layer from ESRI's website. It looks like this:

MultiPolygon (((-99.4097266969388329 28.63827052216430502, -100.11285992001091927 28.63845898525977418, -100.11502942137985883 29.08920919633010271, -99.41330138287827367 29.09272057773335973, -99.4097266969388329 28.63827052216430502)))

Not sure if this is helpful.

  • Do you have any spatial data to go along with your CSV? Jan 29, 2020 at 20:58
  • Do you current see county FIPS borders from your CSV? Or just the table attribute you screenshot above?

    Yes, I have another column from US Counties Vector Layer I downloaded from ArcGIS site. I can match it to my data on FIPS. It looks like this: wkt_geom MultiPolygon (((-101.13538379946879786 44.74944522091215049, -101.21060139983171666 44.70310811353277813, -101.32636980358154233 44.68402360900051917...

  • When I add this data to QGIS as a new Vector Layer it just creates borders for each FIPS.

Use the dissolve tool, which you can find in the Processing Toolbox. Use the "area name" field as the grouping field in the dissolve tool.

  • This is exactly what I was looking for. Thank you!
