Returns the latitude value corresponding to a given geocoord.
How does it work in the search window?
This operation needs only one argument:
The data type of the new column is float.
The examples in this article use values in a data table generated from this CSV file. If you want to try the example for yourself, download the file and upload it to your domain clicking Data upload in the navigation pane. Name the new table my.upload.sample.data and select Current date as Date parsing type. Learn more about uploading data in Uploading log files.
After receiving the confirmation message, you can access the table from the Finder, selecting my → upload → sample → data. When you upload data from a file, all the information is included in a single column called message. To split the values into different columns, you can use the Split operation. Click Toggle Query Editor in the search window toolbar and paste the following LINQ query to get the column required for these examples:
select split(message, ";", 19) as geocoordStrings
We want to get the latitude values corresponding to the geocoord strings in the geocoordStrings column. First, we must convert the strings into geocoord data type, then use the Latitude operation to get the corresponding latitude values.
Step 1: Transform the geocoord strings into data type geocoord
First, use the Geocoord operation to transform the strings in the geocoordStrings column into data type geocoord. Let's call the new column geocoords
Step 2: Get the latitude of the geocoords
Now, create a new column using the Latitude operation and adding the geocoords column as the argument. Call the new column latitude.
Click Create column and you will see the following result:
How does it work in LINQ?
Use the operator
as... and add the operation syntax to create the new column. This is the syntax of the Latitude operation:
Copy the following LINQ script and try the above example on the
