Description

Generates a geocoord from a string as long as it is a valid representation of one of the two supported coordinate systems:

  • Latlon - Based on latitude and longitude and represented as sexagesimal coordinates, using degrees, minutes, seconds, and position (for example 40°24'46.3"N 3°41'43.8"W).

  • Geohash - Hash representation of coordinates, called geohash (for example ezjmguvj).

How does it work in the search window?

Select Create column in the search window toolbar, then select the Geocoord operation. You only need to specify one argument:

Example

(warning) The examples in this article use values in a data table generated from the following CSV file.

...

If you want to try the example by yourself, download the file and upload it to your domain by clicking Data upload in the navigation pane. Name the new table my.upload.geolocation.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 → geolocation → 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 (split) operation. Click Query code editor in the search window toolbar and paste the following LINQ query to save time:

...

Use the operator select... as...  and add the operation syntax to create the new column. The syntax is as follows:

  • geocoord(string)

Example

(warning) Note that you must have uploaded the following CSV file to your Devo domain as explained above to try out this example.
