1 NHD Update Process Improvement Project U.S. Department of the Interior U.S. Geological Survey Kevin McNinch, Dave Hughes, Paul Kimsey

2 Current NHD Tools NHD Geo Edit v3.3.2 –Official release 04/18/2010 –ArcGIS 9.3 sp1 & ArcGIS –NHD Model 1.06

3 Current NHD Tools NHD Geo Edit v3.3.3 –Official release planned 06/07/2010 –ArcGIS 9.3 sp1 & ArcGIS –Compatible with NHD Model 1.07 Permanent Identifiers & ComID (retired in 1 year) External Crosswalk table –Backward compatibility to Model 1.06 –Compatible with NHD Model 2.0 WBD replaces old 1:250k hydrologic units

4 NHD Update Process Improvements WHYWHATHOWBENEFITSMID TERM LONG TERM Short Term 0-1 Years

5 NHD Update Process Improvements

6 What do the Stewards Say: 1.Maintenance is too difficult. 2.Inconsistent results after editing. 3.Need “direct” editing of the NHD data. 4.Quick and simple edits need to be easy. 5.Software installation and performance is an issue.

7 0 Status of Stewardship Today (Sub basins)

8 The Net Result After five years of stewardship, the program is not as advanced as it should be.

9 NHD Update Process Improvements

10 NHD Update Process Improvement Project Charter –02/01/2010 Survey –Distributed to all partners –Compiled results from 23 respondents Requirements Document –Draft April, 2010

11 Process Enhancements, Requirements Specifications: Ranked in order of High to Low: Refactor code for NHD tools and utilities Single Installation Package for all NHD Update Process Tools and Utilities Merge all current NHD toolbars into one toolbar with logical progression of tasks

12 Requirements Specifications: Utilize ArcSDE Versioning to manage NHD Update Process data transactions Allow editing with NHD GeoEdit Tool in geographic coordinate system Create queue for QC checks Create queued edit tool

13 Requirements Specifications: Make all NHD Update Process tools compatible with ESRI Personal Geodatabases (PGDB) and ESRI File Geodatabases (FGDB) Refactor NHD Update Process tools so that they are not reliant on ESRI Task Assistant

14 Requirements Specifications: Incorporate NHD Plus build and refresh QC checks to support NHD Plus creation Update process workflow to use ESRI ArcGIS Job Tracking Extension (JTX) Improve Metadata Process

15 Requirements Specifications: Reach Code Allocation utility process updates Bug Fixes and enhancements from NHD development group list Update tools and installation package to work with ArcGIS 10.0 when released

16 NHD Update Process Current process (29 steps)

20 NHD Update Process Improvements

21 Agile Project Management - SCRUM Requirements are captured as items in a list of “product backlog” Iterative development in a series of four-week “sprints” Product is designed, coded, and tested during the sprint Responsive to changing needs NHD Update Process Improvements

22 Product Noise Level Simple Complex Anarchy Complicated Technology Requirements Far from Agreement Close to Agreement Close to Certainty Far from Certainty Source: Strategic Management and Organizational Dynamics by Ralph Stacey in Agile Software Development with Scrum by Ken Schwaber and Mike Beedle.

26 NHD Update Process Improvements

27 - Level of complexity allows for a much broader audience from “expert” to “knowledgeable users” - Reduces training time - Reduces need for constant technical support -Eliminates re-training

28 Where Does NHD Stewardship Go From Here? Looking beyond lifecycle of current NHD GeoEdit Tools and NHD Stewardship Processes –Current development will be as reusable as possible Begin planning and requirements gathering— create project charter to reflect this work –Completed NHD Architecture Planning Meeting May 13, 2010 Analysis of current process (On-going) Create NHD Update Process that: –Addresses a broader spectrum of NHD users –Simplifies

29 NHD User Base Huge number of Casual Users Many Knowledgeable Users Some Experts

30 NHD Stewardship Addressed Very Well with Edit Tool Complete Edit Capability Poorly Addressed No Intermediate Tool Basic Editing Not Yet Addressed Web Edit Tool Identify and Markup Edits In development Experts Casual Users Knowledgeable Users

31 NHD Update Process Web-Based Markup/Editing Tools –Alabama Web Edit Tool(WET) –Requirements gathering group ongoing for national web markup/editing tool Detailed requirements gathering and analysis Improve web services

32 NHD Update Process Evaluating other technologies, trends, and tools for future of Vector Data Stewardship –Open source or COTS tools –Open data standards –Geosyncronization –Volunteered Geographic Information (VGI)
