    Maps & Geocoding

    jagam jaga win

      •   Maps – Drill through from Super Region to DMA Level ( not MSA Level) possible ?

      •  Maps – How many dimension possible to display on the Map

        - vary by size, by color, by shapes

      - Is it possible to add pushpins & ribbons

      •  Maps – Can we locate postal address exactly on the MAP ?

      FOR ANY address across the globe ?

      up to street level ?

      •  Maps – Geocodes by Tableau and Goecodes from Google MAPS not exacty the same .. why?

      •  Security – Can we restrict columns or set rows based on user in Tableau. OR does it have to done at the backend database layer

       

      Thanks in advance

       

      Please add your advice ....

          The security bit can be handled in a number of ways, including based on the logged in user:

          User Filters and Row Level Security | Tableau Software

           

          I will leave the map questions to the experts.

            Yes, but not using traditional Tableau hierarchies. 

             

            •  Maps – How many dimension possible to display on the Map

              - vary by size, by color, by shapes

            - Is it possible to add pushpins & ribbons

             

            2 (X,Y) although you could color encode Z axis to achieve contour/depth/height

            Size - you can swap X,Y lat/long pairs using a measure swapper.  With 64-bit, the size is technically unlimited.

            Color - Tableau uses Hex

            Shapes - Tableau allows custom shapes, but if you are meaning Geo, then poly, line and point.  You can merge Polys and Lines to Point prior to ingesting in Tableau.  Pushpins & Ribbons yes, Tableau allows custom shapes.

             

            •  Maps – Can we locate postal address exactly on the MAP ?

            Yes, by pre-processing/geocoding.  You can also ingest GPS.

             

            FOR ANY address across the globe ?

            Yes, you can ingest any lat/long and join the address data

             

            up to street level ?

            •  Maps – Geocodes by Tableau and Goecodes from Google MAPS not exacty the same .. why?

            Google's geocoder API is not 100% accurate.

            Why the maps do not "display" the same - datum.  Google uses 900913.

             

            •  Security – Can we restrict columns or set rows based on user in Tableau. OR does it have to done at the backend database layer

            Yes. You can do this using a mix of API and an open parameter.
