Hi folks,
I am looking for a tool that I can use to select the highest value within a set of similar values.
The values are alphanumeric, and are essentially two parts merged into one field - a master ID to the left of a decimal and a segment ID to the right of the decimal. Each "master" has a different number of segments. I would like to select the feature with the higest segment ID for each unique master ID. There are roughly 5000 unique values in this field.
For instance, in a series of AB1.1, AB1.2, AB1.3, YZ4.1, YZ4.2, both AB1.3and YZ4.2 would be selected.
I would prefer to do this operation with the out-of-the- box functionality & GP tools, but could work with Python if necessary (I am an absolute novice). Any suggestions on how to approach this??
Thanks!!
Sean
