As of December 1, 2022, the Markup App is no longer accepting incoming markups. You can still log in to review your markup history, browse the map, or identify features, but cannot submit markups. Markups submitted through November 30, 2022 will be considered for review and implementation in the final static version of the NHD and WBD. Any markups submitted after the deadline will not be considered for implementation..
Similar to "marking up" a printed map, a "markup" is a digital suggestion for improving the USGS National Hydrography Dataset (NHD) or Watershed Boundary Dataset (WBD). Markups can suggest edits to feature geometry (using a point, polyline, or polygon shape) and/or attributes.
Note: Markups are suggestions for improvement to NHD and WBD datasets; no actual edits occur in the Markup App.
For example, the markup shown below suggests a geometry edit -- redrawing the line geometry for the NHDFlowline coastline feature:
The following markup suggests an attribute edit -- changing the FlowDir attribute to the value of "Uninitialized/0".
When you create a markup, it will contain the following attribute fields:
