NC OneMap: GIS Data Layer Categories for the Viewer's Table of Contents|
The "Table of Contents" (TOC) category that each of the layers in the NC OneMap viewer is assigned to
is based upon the 19 ISO Metadata Theme Topic Categories. The NC OneMap design team has decided to group both
the inland and oceanic water resources into a single category in the viewer because some water resources
layers could be assigned to either category. The NC OneMap design team also decided that it
would be easier for users of the viewer if Landcover was located in its own category, rather than for
it to be grouped with orthophotos, satellite imagery or scanned topographic maps.
The NC OneMap design team has assigned an abbreviated name to these categories because there is limited screen
real-estate in the map viewer and the official ISO topic names are rather lengthy. Below is a table that
cross-references the official ISO topic names, the older FGDC topic names you may be familiar with, and
the NC OneMap layer "Table of Contents" category abbreviations.
If you are an NC OneMap data provider, please note: When you are creating your FGDC compliant
metadata records or your WMS Capabilities XML files, you should always use the official ISO metadata
theme topic names in all of your <Keyword> sections. We are only using the abbreviated versions
in the map viewer's "Table of Contents" because of user interface considerations.

resources describing irrigation, aquaculture, herding, and pests and diseases
affecting crops and livestock
||Agriculture and Farming
| Atmosphere, climatology, and meteorology
This category refers to atmospheric processes and phenomena. For example, resources describing
cloud cover, weather, atmospheric conditions, climate change, and precipitation.
|| Atmospheric and Climatic Data
| Biologic and ecologic
This category refers to naturally occurring flora and fauna. For example, resources describing
wildlife, biological sciences, ecology, wilderness, sea life, wetlands, and habitats.
|| Biologic and Ecologic Information
| Business and economic
This category refers to economic activities or employment. For example, resources describing
labor, revenue, commerce, industry, tourism and ecotourism, forestry, fisheries, commercial or
subsistence hunting, and exploration and exploitation of resources such as minerals, oil, and gas.

This category refers to land use. For example, resources describing zoning maps, cadastral surveys,
and land ownership, such as Tax Parcels.
||Cadastral & Legal Land Descriptions
| Cultural, society, and demographic
This category refers to the characteristics of societies and cultures.
For example, resources describing natural settlements, anthropology, archaeology, education,
traditional beliefs, manners and customs, demographic data, crime and justice, recreational areas
and activities, social impact assessments, and census information.
|| Society, Cultural and Demographic Information
| Elevation and derived products
This category refers to height above or below sea level. For example, resources describing
altitude, bathymetry, digital elevation models, slope, and products derived from this information
|| Elevation and Derived Products
| Environment and conservation
This category refers to environmental resources, protection, and conservation. For example,
resources describing pollution, waste storage and treatment, environmental impact assessment,
environmental risk, and nature reserves.
|| Environmental Monitoring and Modeling
| Facilities and structures
This category refers to man-made construction. For example, resources describing buildings,
museums, churches, schools, factories, housing, monuments, and towers.
|| Facilities, Buildings and Structures
| Geological and geophysical
This category refers to the earth sciences. For example, resources describing geophysical
features and processes, minerals, the composition, structure and origin of the earth’s rocks,
earthquakes, volcanic activity, landslides, gravity information, soils, permafrost,
hydrogeology, and erosion.
|| Geologic and Geophysical Information
| Human health and disease
This category refers to health services, human ecology, and safety. For example, resources
describing human disease and illness, factors affecting health, hygiene, mental and
physical health, substance abuse, and health services.
|| Human Health and Disease
| Imagery and base maps and earth cover
This category refers to base maps. For example, resources describing land cover, topographic maps,
and classified and unclassified images.
|| Base Maps, Scanned Maps and Charts
Note: The NC OneMap design team has decided that landcover will remain in its own category in the
map viewer TOC. All landcover layers will be found in this grouping in the viewer, instead of
the Imagery-Basemap category.
|| Earth Surface Characteristics and Land Cover
| Locations and geodetic networks
This category refers to positional information and services. For example, resources describing
addresses, geodetic networks, postal zones and services, control points, and place names.
|| Geodetic Networks and Control Points
| Military and intelligence
This category refers to military bases, structures, and activities. For example, resources
describing barracks, training grounds, military transportation, and information collection.
| Transportation networks
This category refers to the means and aids for conveying people and goods. For example,
resources describing roads, airports and airstrips, shipping routes, tunnels, nautical charts,
vehicle or vessel location, aeronautical charts, and railways
|| Transportation Networks and Models
| Utility and communication networks
This category refers to energy, water and waste systems, and communications infrastructure and
services. For example, resources describing hydroelectricity, geothermal, solar, and nuclear
sources of energy, water purification and distribution, sewage collection and disposal,
electricity and gas distribution, data communication, telecommunication, radio,
internet, and other communication networks
|| Utility Distribution Networks
| Inland water resources
This category refers to inland water features, drainage systems, and their characteristics.
For example, resources describing rivers and glaciers, salt lakes, water use plans, dams,
currents, floods, water quality, and hydrographic charts.
|| Inland Water Resources and Characteristics
| Oceans and estuaries
This category refers to the features and characteristics of salt water bodies excluding
inland waters. For example, resources describing tides, tidal waves, coastal information, and reefs.
