Use BaseURL and locate NID data

[waswapeter]

In the previous api the following URLs could work

1. https://water.usace.army.mil/a2w/CWMS_CRREL.cwms_data_api.get_a2w_webservices_json # this I used as the baseURL
2. https://water.usace.army.mil/a2w/CWMS_CRREL.cwms_data_api.get_nidid_json # this I used to access data from National Inventory of Dams (NID).
   However, these nolonger work. Could anyone help me fomulate 1 and 2, so that am able to acquire data from the new api?.
   Thank you in advance.

Start here : The data is available in JSON. The Swagger UI has more information https://cwms-data.usace.army.mil/cwms-data/swagger-ui.html If you find the data you want, swagger will formulate the json get url for you.

Admittedly, I am still struggling with the change myself. The new system requires timestamps for the json get to work properly and thus far I have not been able to replace the same functionality that I previously had. A bit frustrating, knowing I had been using the legacy system for years without problems. Good luck!

Hi @HarkenBanks, thanks for immediate response.
However, @MikeNeilson, could you please help me to understand "category-office-id" and "location-office-id", giving examples for each will help to understand more. Thank you very much in advance!

Those fields indicate which district controls/configures that location or category.

The fields can either be used to limit search to specific USACE districts (generally you will get faster responses doing this) or to indicate which district is responsible for that data if you need to ask additional questions.

For the NID data, CWMS (and A2W) aren't the authoritative source of data, those were provided for convience, and admittedtly we just didn't think about them when porting the API as they were served out by another system (Access-to-Water) that has also just been modernized.

@JeremyDKellett is there an actual authoritative source of the National Inventory of Dams data that has an API the @waswapeter can use?

If not we can expose that data again through CDA, that data itself should still be within our database though we will want to make sure we have a mechanism of keeping it up-to-date - not that I think it changes all that often..
