Watershed Boundary Dataset Concepts

The video tutorial on the Watershed Boundary Dataset (WBD) covers its structure, organization, and role in the national hydrography data collection. It explains the hierarchical system of hydrologic units, maintenance tasks, and cross-border harmonization efforts. The tutorial also highlights collaboration among agencies and provides information on accessing WBD data through various resources.

What is the primary purpose of the Watershed Boundary Dataset (WBD)?

• To track weather patterns

• To map underground water sources

• To define political boundaries

• To organize surface water features

How are the largest hydrologic units in the WBD identified?

• By a two-digit code

• By a color code

• By a shape code

• By a letter code

What is the smallest required hydrologic unit code in the WBD?

• 10-digit code

• 12-digit code

• 8-digit code

• 14-digit code

Which organizations were involved in the development of the WBD?

• NASA and NOAA

• USGS and EPA

• FBI and CIA

• FDA and CDC

What is the role of a WBD Principal Steward?

• To enforce environmental laws

• To coordinate WBD data editing

• To oversee local water quality

• To manage political boundaries

What is the main goal of the cross-border harmonization efforts between the U.S. and Canada?

• To monitor wildlife migration

• To create new political boundaries

• To develop seamless hydrographic data

• To establish new trade agreements

Which phase involves the development of harmonized hydrography between the U.S. and Canada?

• Phase 3

• Phase 1

• Phase 2

• Phase 4

How can WBD data be accessed for use in GIS software?

• By downloading from the USGS FTP site

• By subscribing to a monthly service

• Only through physical maps

• By purchasing from a local store

What additional option does WBD offer for accessing data besides online map services and downloads?

• Weekly newsletters

• Live satellite feed

• Packaged with hydrography data

• Printed maps

What is the relationship between WBD and the National Hydrography Dataset (NHD)?

• They are unrelated datasets

• WBD is a companion dataset to NHD

• They are competing datasets

• NHD is a subset of WBD
