Welcome to the interactive North Carolina Wetland Mapping and Analysis Program web application, NCWetMAP. This site is designed to explore, investigate, and analyze the North Carolina (and some of South Carolina) wetland monitoring sites and surrounding wetland related geographic data. Chosen geographic data layers are provided as analysis inputs to assess the area environmental characteristics for chosen wetlands of study. Included geographic data, information, and tools are designed with wetland monitoring site related data in mind.

Many features are available, organized and integrated across the following six tabs: Data, Select, Buffers, Query, NLCD, MapSketch, and Tools. Click the arrow at the top of the Data, Maps, and Tools expandable pane left of the map to use.

For easier exploration and analysis without clutter, it is highly recommended to first zoom into an area of interest, then turn on desired data layers.

  • Click-drag to pan map.
  • Scroll mouse wheel to zoom in or out.
  • The zoom tool at the upper-left map corner can also be used to zoom in or out.
  • Click the NC icon to return to the original map extent.

  • To quickly zoom to a specific area, hold down the Shift key while left-click-dragging the mouse to define a box on the map you want to be zoomed to. Release the left mouse button after defining the area and you will be zoomed in to that location.

  • Use the built-in Search tool at the upper-left of the map to find an address or place. Map will zoom in to the location with a marker and info popup window with more choices.

  • Use the Zoom To… tool at the upper-right of the map to select from a list of counties and be quickly zoomed to the extent of your chosen county.

  • Besides using the right and left scroll arrows, Tabs can also be selected from a dropdown list by clicking on the arrow to the far right.

Data Tab:
Various basemaps are available from a toggleable list.

Wetlands Monitoring Sites and related geographic Data Layers can be toggled on/off.

Weather related Data Layers are available.

Additional basemaps with extra information are available.

Transparency for some Data Layers can be adjusted with these sliders:

Information about a Wetlands Monitoring Site is available by clicking your mouse on a site symbol.

Select Tab:
Interactively select a single or group of Wetlands Monitoring Sites. Selected data can be saved to a table locally.

Buffer Tab:
Interactively select by buffer, with a chosen distance and measure unit, any of the Wetlands Monitoring Sites. Selected data can be saved to a table locally. The first line inside the buffer indicates half the entered distance. The second line inside the buffer indicates a quarter of the entered distance.

Query Tab:
This is the Select by Attributes tool. Attributes from the Wetland Monitoring Sites Data Layer can be used to build query statements and make selections. Only selected sites will appear in the map. Options to create a new selection, add to current selection, or remove from current selection are available. Query statements can also be saved and loaded for repeated use within the same web session. Selected data based on a query result can be saved to a table locally.

This tab allows for interactive National Land Cover Database area analysis for impervious surfaces and the full land cover classifications. Dynamic, interactive charts area created along with percent land cover for custom buffers and polygon areas created on demand.

MapSketch Tab:
A variety of graphics, measurements, buffers, and text can be added and edited on the map.

Tools Tab:
Enter a map title, choose from several page formats, and print the current map to a downloadable PDF, JPG, GIF, SVG, EPS, PNG8, or PNG32 file.

Measure areas, distances, capture location coordinates on the map.

Create an interactive elevation profile.

View StreetView imagery wherever StreetView coverage is available.

More Tips:

  • Multiple buffer graphics can remain on the map until removed using the clear buffers button. This means in the Buffer Tab, multiple buffers can be drawn, revealing selected data located within buffer intersections. This data can then be reselected interactively with tools in the Select Tab
    • Toggle Table buttons may have to be clicked twice to initially activate.
    • Tables are synced to selected features. Click a record in the first column to see the corresponding feature highlighted on the map and be zoomed in closer. Click column header to clear highlight symbol.
    • When zoomed in the map close enough, labels for Counties, HUC8, and HUC12 features will appear.
    • Many buttons have tooltips.

    About the NC Wetlands Monitoring Website

    This website and geographic information systems (GIS) application was developed by RTI International for North Carolina State University (NCSU) under a U.S. EPA Region 4 Wetland Program Development Grant (WPDG) to design and implement a comprehensive wetland monitoring network and spatial database for NC. The NC Department of Environmental Quality (DEQ) has been monitoring wetlands in NC for over a decade, with data collected on the condition, and physical and biological characteristics of over 200 wetland sites. In addition, over the past three years wetland stakeholders have worked with NC DEQ to revise and implement NC’s Wetland Program Plan (WPP), which includes a wetland monitoring component. As a land-grant institution whose mission is to protect the health and well-being of the state’s citizens and natural resources, NCSU seeks to expand the work done by NC DEQ by executing several key components documented in NC’s WPP, including continuation and expansion of the monitoring of hydrology, water quality, soils, and biota at 16 long-term wetland monitoring sites.

    The ultimate goal of the WPDG is to use data from these 16 sites along with legacy data from the DEQ sites to assess temporal and spatial trends in wetland characteristics, condition, and function; establish baseline and reference metrics for wetland mitigation; and determine how to measure and assess long-term changes in wetland functions and ecosystem services. As part of this grant this website provides a comprehensive spatial database for viewing monitoring data collected on the legacy and long-term sites. Although the spatial database’s initial focus is on the legacy and long term data, it has been designed to hold wetlands data from a wide number of entities and provide efficient access to wetland information for the project and for local, state, and federal government agencies as well as the public, including mitigation providers and conservation organizations.

    National Land Cover Database (NLCD)
    2011. The National Land Cover Database (NLCD) Land Cover Collection is produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium ( The MRLC Consortium is a partnership of Federal agencies, consisting of the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service, the U.S. Forest Service, the National Park Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management, NASA, and the U.S. Army Corps of Engineers. A primary goal of the MRLC Consortium is to generate current, consistent, and seamless national datasets of land cover, percent developed imperviousness, and percent tree canopy.
