Ping: curtvprice -- RE: USGS waterservices xml

JamesCrandall

Curt or anyone else that has experience with the USGS waterservices webservice,

We have developed some Geoprocessing tools that are integrating the Instantaneous Values Web Service (http://waterservices.usgs.gov/rest/IV-Service.html) and using the return xml to create hydrographs, dynamic maps (.mxd's) that add these hydrographs as attachments to a FGDB, and some limited efforts to publish these to our internal ArcGIS Online portal. These are mostly tools for status reporting and supplemental materials in larger reports.  All is working great but we'd like to expand them a bit...

Without getting too far into the details of the geoprocessing tools and the outputs, we are also interested in accessing some of the other more detailed statistics that are available from the groundwaterwatch page(s) that generate the percentile ranking statistics over the period of record for individual wells for each month.

What is not clear is that the DV Webservice (http://waterservices.usgs.gov/rest/DV-Test-Tool.html) inidcates that a statistic "statCd" parameter can be included in the url string.  And looking at the list of Statistics Codes (http://help.waterdata.usgs.gov/stat_code), it appears that these percentile values are available.  However, when ever I include this parameter into the url string, nothing is returned. For example,

http://waterservices.usgs.gov/nwis/dv/?format=waterml,1.1&sites=262218080070101&period=P120D&parameterCd=62601&statCd=01900


Any tips?  Is the chart in the site statistic section from this page http://groundwaterwatch.usgs.gov/AWLSites.asp?S=264005080233501&ncd= available from one of the webservices?  Can it generate an XML construct?

Thanks!

James,

I'm not very familiar with this service. I honestly think the best way to address your question is to contact them by email. From the the Automated Retrievals FAQ:

How do I get help refining my URL query?
Please tell us what you want to do by sending an email to gs-w_support_nwisweb@usgs.gov.

Note to blatantly advertise, but everyone should know that a great deal of water information is available in a variety of formats from http://water.usgs.gov. This includes interactive web data retrievals, as well as embeddable web graphs (supports multiple parameters now!), and yes, XML services for your custom applications.

One of the coolest ways to get water data, IMHO, (esp. if you a fisherman or river rafter, or live near the water) is the recently enhanced wateralert service.

Have a safe weekend out on the water, everyone! Wear your PFD!
