Non-Vegetative Documentation


3.4 NON-VEGETATIVE FEATURES--MAJOR CODE 080

Features digitized in this category portray information about the naturally occurring, non-vegetated surface of the Earth; such as lava, sand, and gravel features. While numerous other non-vegetative features exist, they are digitized in other categories that are more applicable. For example, features that are the result of human activity, such as mines, are digitized in Manmade Features (major code 200), and features associated with water, such as glaciers, are digitized in Hydrography (major code 050).

It is important to note that most non-vegetative features are shown with the same, or very similar, pattern. At 1:24,000 scale, gravel areas and glacial moraines are shown using pattern USGS 22. The context and label must be used to decide if an area is a gravel area or glacial moraine. At 1:100,000 scale, only one pattern (USGS 17) is used for all of the features in this category, except lava. The context and label must always be used to decide which is the appropriate code to use. On provisional edition maps, all of the features in this category are outlined with a dashed symbol. The context and label must always be used to decide which is the appropriate code to use.

3.4.1 General Principles

3.4.1.1 Node Attribute Codes

There are no node attribute codes.

3.4.1.2 Area Attribute Codes

Non-vegetative surface features are shown on the map as an area of pattern or tint. The digitized line depicting the limits of the non-vegetative feature is unattributed.

3.4.1.3 Line Attribute Codes

There are no general principles that apply to line attribute codes.

3.4.1.4 Single-Point Attribute Codes

There are no single-point attribute codes.

3.4.1.5 General Purpose Attribute Codes

There are no general purpose attribute codes.

3.4.1.6 Descriptive Attribute Codes

There are no descriptive attribute codes.

3.4.1.7 Parameter Attribute Codes

There are no general principles that apply to parameter attribute codes.

3.4.2 Node Attribute Codes

There are no attribute codes for nodes in this category.

3.4.3 Area Attribute Codes

        000 0000 Outside area

This code is described in section 3.0.6.1.

        080 0100 Glacial moraine

This code identifies an area shown by a brown area pattern, which is the same as, or similar to, most features in this category. Generally the symbol is not labeled; the surrounding area must be examined to distinguish a glacial moraine from other features shown by the same pattern. The glacier itself is collected in the hydrography category.

        080 0101 Gravel area

This code identifies an area shown by a brown area pattern, which is the same as, or similar to, most features in this category. The feature's context and any applicable labels must be used to distinguish gravel area from other features shown by the same pattern.

        080 0102 Sand area

This code identifies an area shown by a brown area pattern which is the same as, or similar to, most features in this category. The feature's context and any applicable labels must be used to distinguish sand area from other features shown by the same pattern.

        080 0103 Shifting sand or dune area

This code is no longer used. See code 080 0102.

        080 0104 Lava

This code identifies an area shown by symbols 328(A), 135.5(B), 535.6(C), or 2112.07(D).

        080 0105 Void area

The area beyond the national boundary is coded as a void area, to distinguish it from the background area.

3.4.4 Line Attribute Codes

        080 0200 Closure line

This code is no longer used. Unattributed lines are used to close off areas.

        080 0299 Processing line

This code is described in section 3.0.6.3.

3.4.5 Single-Point Attribute Codes

There are no longer any single-point attribute codes in this category.

        080 0300 Located surface feature

This feature is no longer collected.

3.4.6 General Purpose Attribute Codes

There are no general purpose attribute codes in this category.

3.4.7 Descriptive Attribute Codes

There are no descriptive attribute codes in this category.

3.4.8 Parameter Attribute Codes

        080 0000 Photorevised feature

This code is described in section 3.0.6.4.

        088 0000 Best estimate of position or classification

This code is no longer used.

        089 00-- Coincident feature

This code is no longer used.
