I have a table of polylines, each with ten attributes. Two of the attributes are used as values in a layers symbology Feature>Categories>Unique_Values. I need to view data using either or both of these values in data visualisation often in conjuction wiith the layer data editor. I could switch between attributes within the layer but this means setting up the colour scheme each time for the attribute used. I have not found a way of saving and reusing these colour schemes so the alternative is to configure two layers sharing the same table ( + editor). Is this approach robust and unlikely to cause problems or can it be used within certain constraints? (ARCDesktop 10.5.1, Bootcamp, MacIOS Mojave)
Solved! Go to Solution.
If you are going to be doing any edits/changes and are afraid that a change may impact one or the other scenario... use separate files, unless you are totally confident that you could unravel a change at some point in the future should an error be found or change in parameters is needed. Storage space is cheap, time isn't
copy the table to a new file and set each one up as your want... would be the easiest solution
A given feature class can have multiple layers referencing it. If you are in ArcMap, just drag the same table/feature class from the Catalog pane into the map twice, and then set the symbology you want.
Thank you for your responses. I have a table of extracted trivariant gausian cluster data, 19 distributions in all . One table attribute identifies the table records in each of these distributions. Two of the cluster variants are space ( latitude & longitude) and the same spatial feature occurs across many clusters. A second table attribute associates the records belonging to each spatial feature across all clusters. (I could do it with one feature by adjusting the first attribute but that would change the base data which I don't want to do. ). The membership of a record to a spatial feature is partially visual so automation is not an answer. There are a small number of record instances which have been incorectly posted to the wrong clusters ( distribution outliers) which need correction so the ideal process is to edit both table attributes at the same time, i.e. correct the data and assign records to the spatial features. Not knowing the internal working of ARCgis I am concerned that I could corrupt the data base in some way whilst doing this and I appreciate Dan's direct approach but Joshua's suggestion meets my needs; however is record access handled in these circumstances in such a way that table integrity and data access issues such as deadlock are avoided?
