Represent geocoord format (reprgeo)

[ 1 Description ] [ 2 How does it work in the search window? ] [ 3 How does it work in LINQ? ]

Description

Transform a given geocoord into a string following a specific format (:type:value), where type is the geocoord type (latlon or geohash). For example:

For geocoord 78z0, you will get :geohash:78z0
For geocoord 36°N 20°W, you will get :latlon:36°N 20°W

This operation needs only one argument:

Argument	Data type

Argument	Data type
Geocoord ^mandatory	geocoord

The data type of the new column is geocoord.

Example

The examples in this article use values in a data table generated from the following 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:

from my.upload.sample.data
select split(message, ";", 8) as geocoordStrings

We want to represent the strings in the geocoordStrings column in the format :type:value. First, we must transform the strings to data type geocoord.

Step 1: Transform the geocoord strings into data type geocoord

First, we must transform the strings in the geocoordStrings to data type geocoord using the Geocoord (geocoord) operation. Add the geocoordStrings column as the argument. Let's call the new column geocoords.

Step 2: Format the geocoords (:type:value)

Now, create a new column using the Represent geocoord format operation and adding the geocoords column as the argument. Call the new column formattedGeocoord.

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as... and add the operation syntax to create the new column. These are the valid formats of the Represent geocoord format operation:

reprgeo(geocoord)
reprgeo(geocoord(string))

Example

You must have uploaded the following CSV file to your Devo domain as explained above to try out the following example.

Copy the following LINQ script and try the above example on the my.upload.geolocation.data table.
