Split Lat/Long Actor
This actor looks for columns that contain both latitude and longitude coordinates and splits them into two separate columns. It leaves the latitude in the original column and moves the longitude to a new column immediately next to the latitude.

Required Packages :
...
- FCRepoKepler - script is based on the RowAnalyzer class in fcrepo.kepler.RowAnalyzer.

Input port :

- input : ObjectToken containing a Python tuple or Java array with 2 items :
- the current row number as an integer.
- an ordered list of columns in the row.

The "Split Lat/Long" script also needs a list of indexes for the columns that contain lat/long coordinates. This can be acquired in one of two ways:
A string parameter on the PythonActor named 'indexes'
OR
A port named 'indexes' containing a StringToken.
In either case, the string must contain either a comma-separated list of column numbers or a formula describing a regular sequence that can be used to generate the list. The format of the formula is START + INCREMENT * COUNT. For example, the formula 7+4*10 means there are 10 columns in the list, coordinates occur every 4 columns starting with column 7. This would generate the list 7,11,15,19,23,27,31,35,39,43.

- output : ObjectToken containing a Python tuple or Java array with 4 items :
- the current row number as an integer.
- a tuple/array of values for each column in the row.
- a tuple/array of changes made.
- a tuple/array of errors encountered.
The "Split Lat/Long" PythonActor is used in the following workflows:

Kepler Workflows
Kepler workflows were developed to illustrate how Kepler might be used as an accessioner's workbench.
