Do you have a sample workflow using Open Route Service API to share?

Question

Hi,

I am looking for a free service to geocode address to longitudes and latitudes. It seems Google geocode API has no free tier any more. I signed up for the Open Route Service today. If you have a geocode address workflow using this service to share with me, that will be greatly appreciated!

Thank you,

Jovia

Hi @DavidThorpe ,

I am making progress. I added in steps from the Geocode Address macro to the workflow you shared with me. It seems working (attached). I want to know if one of the optional fields has null value, how to handle the nulls in the formula step for the URL?

In general, should I pick the highest confidence value per address?

Thank you so much !!

Hi @jovia

If you take a look at the API documentation:

https://openrouteservice.org/dev/#/api-docs/geocode/search/get

You can see the requests are structured with a series of optional values (country code, neighbourhood etc.) you can search with, or you can simply search with open text.

I have created the following simple workflow which will allow you to enter your own key into the API Key Text Input, and your own free-form addresses (I have used our London office location 186 City Road, London, EC1V2NT) to return JSON which can then be filtered and parsed for the items you need (lat and long values)

Simply filter/parse/transform for Contains([JSON_Name],"coordinates"), or other such detail you require.

You can add more search parameters (for instance my search returned several results, so I may wish to search by country code as an additional field, or add the country to the address string for parsing) by using the online interactive documentation, which is pretty neat, then adding them in as fields in the top Text Input tool and adding them into the replace funtion in the Formula.

Give it a go with your own key and data, let me know how you get on!

Hi @DavidThorpe ,

Thank you for your information. I am working on US addresses. I downloaded the geocode address macro. Do you happen to know what are the equivalent US information to 'Neighborhood' and 'Region'. Which field is equivalent to the States in US? I tried leaving the neighborhood and region fields blank. I got parse error: type mismatch in operator.

Should I delete the neighbourhood and region parameters if I am leaving them blank? Then I need to modify the URL too.

Do you happen to know what is the URL for US addresses? Where to put in the state info in the URL?

Thank you !
