Abstract: Daniel Pearson, Joseph Vrabel and Ramona Neafie will present TXWSC approaches for web development for public-facing applications.  Recent efforts (2016-2017) provide easier access to USGS science products and dynamic data visualization that connect cooperators and the general public to these products via desktop and mobile solutions.  TXWSC staff make use of web analytics to hone the messaging on web products, make UI changes that allow for easier navigation and help 'tell the story' of the products to management and decision makers at USGS.  For more information about recent products go to:

Daniel Pearson -- Daniel has been with the USGS Texas Water Science Center since 2002. He currently serves as the Data and Spatial Studies Section Chief in Austin, TX. He provides technical expertise to Texas Water Science Center cooperators and staff, and oversees a team of geographers, IT specialists, and hydrologists whose function is to produce innovative geospatial solutions in the water science arena.

Joe Vrabel -- Joe has been with the USGS since 1996 first in Reston, VA, then with the Maryland Water Science Center (2000-2005), then the Texas Water Science Center (2005-present). He develops web-based mapping and data applications. His expertise includes: Client-Side JavaScript Development and Server-Side Databases and Data Services.

Ramona Neafie -- Ramona has been with the USGS since 1996, and with the Texas Water Science Center since 2014. She serves as the design, usability, and web analytics lead for the Texas Water Science Center internal and public facing web site and social media presence. Her expertise includes: Web Analytics and Web Design and Usability.

Presentation Q/A

  1. Linda Debrewer: Is there an interface for this service? Do you use the Groundwater Watch stats approach or is there a different one?
    1. (inaudible on recording)
  2. Lindsay Carr: Can you share the URL for the NWS flood stages? And how often is that table updated?
    1. This is an ongoing conversation between USGS and NWS. The TX data have additional quality checking, but that is not the case with the rest of the national product. Marie Peppler would be the contact for this.

  3. Participant: Do you intend for the API in its present state to be used by other developers? Or is it still being refined before it's shared?
    1. It’s our motivation to provide a product and maintenance more widely. If we go national with anything we’ll work with headquarters.

  4. Blake Draper (WIM): to Dan/Joe/Ramona in TX: does CWIS have any sort of homepage or documentation site?
    1. No, not yet since it is not a national release.
  5. Participant: It's really exciting to see the work being done for Texas and working towards national data products from the Texas Water team. Thank you!
  6. Participant: Dan/Ramona/Joe - Question about your analytics approach for your APIs - how do you track usage of your endpoints for CWIS, USGS Javascript search API, or GWIS?
    1. Most is handled on the database side, database calls through SQL.

  7. Participant: Details on Sophia Liu's hackathon? Sounds like something that might have some good output to check out!
    1. It's at FEMA headquarters, planned for Oct. 21.
