- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE to verify and validate the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set was calculated from latitude/longitude coordinates. The positional accuracy is unknown. Note that some locations are the center point of broad volcanic fields, and that even at individual volcanoes the coordinates given do not necessarily match the eruption site. Tens of kilometers may separate eruptive centers of a single volcano, particularly in large caldera complexes and rift settings.

- Entity Type Definition
- The points represent a vent or opening in the surface of the Earth through which magma erupts; it is also the landform that is constructed by the erupted material. This data set includes volcanoes thought to be active in the last 10,000 years (Holocene), in and near the United States.

- NUMBER
- The volcano number, based on a system developed by the Catalog of Active Volcanoes of the World (CAVW), is in the format ####-##-. The first two numerals identify the region, the next two identify the subregion, and the last two or three (after the hyphen) identify individual volcanoes in that subregion. When there are three final characters and the last character is "=", the number is the same as that found in the CAVW; where the last character is "-", the number is not found in the CAVW because the region was not numbered in the CAVW or has been renumbered for this data set; where the last character is a number, the volcano is in an area included in the CAVW but the number is a new one that does not appear in the CAVW.

- TYPE
- The shape and size of the volcano (morphology).
- Caldera(s)
- A large volcanic collapse depression, commonly circular or elliptical when seen from above.
- Cinder cone(s)
- A steep-sided volcano formed by the explosive eruption of cinders that form around a vent.
- Complex volcano(es)
- A volcano composed of a mixture of landforms. In most cases, they occur because of changes either in eruptive habit or in location of the principal vent area.
- Fissure vents
- Linear volcanic vents through which lava erupts, usually without any explosive activity. The vents are usually a few meters wide and may be many kilometers long.
- Lava dome(s)
- A rounded, steep-sided mount that forms when very viscous lava is extruded from a volcanic vent.
- Maar(s)
- Shallow, flat-floored craters above diatremes (volcanic vents or pipes drilled through rocks by the explosive energy of gas-charged magmas) as a result of a violent expansion of magmatic gas or steam. Maars often fill with water to form a lake.
- Pyroclastic cone(s)
- A volcanic cone composed of fragmented material ejected from a volcano.
- Pyroclastic shield
- A volcano with long, gentle slopes composed of ejected fragmental material.
- Shield volcano(es)
- A volcano that resembles an inverted warrior's shield, with broad, gentle slopes, built by multiple eruptions of fluid basalt lava. Basalt lava tends to build enormous, low-angle cones because it flows across the ground easily and can form lava tubes that enable lava to flow tens of kilometers from an erupting vent with very little cooling.
- Stratovolcano(es)
- A steep-sided volcano built by lava flows and tephra deposits. Tephra is solid material of all sizes explosively ejected from a volcano into the atmosphere.
- Stratovolcano ?
- A steep-sided volcano possibly built by lava flows and tephra deposits. Tephra is solid material of all sizes explosively ejected from a volcano into the atmosphere.
- Subglacial volcano
- A volcanic form produced by eruptions beneath a glacier or beneath the surface of a lake within a glacier.
- Submarine volcano
- A volcanic form produced by eruptions in the ocean.
- Submarine volcano ?
- A possible volcanic form produced by eruptions in the ocean.
- Tuff cone(s)
- A volcanic cone formed by the interaction of basaltic magma and water.
- Tuff rings
- Shallow, flat-floored craters formed by the interaction of magma and water.
- Volcanic field
- A collection of cinder cones and (or) lava flows.
- Unknown
- The volcano morphology is not known.
