3.3 VEGETATIVE SURFACE COVER--MAJOR CODE 070

This category includes woods or brush-wood, scrub, orchards or plantations, scattered trees, and vineyards. Additional vegetative features that are associated with wetland or submerged areas, such as marshes and swamps, mangrove, and cranberry bogs, are collected under Hydrography (major code 050).

The photorevision code is not applicable to Vegetative Surface Cover. Normally photorevised vegetation is shown in green, rather than purple, and, therefore, it is not distinguishable as photorevised. If, however, scrub, orchard or plantation, vineyard, or scattered trees does appear in purple, collect it according to normal guidelines and ignore the fact that it is photorevised.

3.3.1 General Principles

3.3.1.1 Node Attribute Codes

There are no node attribute codes.

3.3.1.2 Area Attribute Codes

Vegetative surface cover information is shown on the map source as an area of pattern or tint. The digitized line depicting the limits of the vegetative feature is unattributed.

3.3.1.3 Line Attribute Codes

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

3.3.1.4 Single-Point Attribute Codes

There are no single-point attribute codes.

3.3.1.5 General Purpose Attribute Codes

There are no general purpose attribute codes.

3.3.1.6 Descriptive Attribute Codes

There are no descriptive attribute codes.

3.3.1.7 Parameter Attribute Codes

There are no parameter attribute codes.

3.3.2 Node Attribute Codes

There are no attribute codes for nodes in this category.

3.3.3 Area Attribute Codes

        000 0000 Outside area

This code is described in section 3.0.6.1.

        070 0101 Woods or brushwood

Woods are shown by symbols 600, 604(A); 152.1, 152.2, 152.3, 152.5(B); 552.1, 552.2, 552.3, 552.5(C); or 2402.01(D).

If a wooded area is partially overprinted by swamp, submerged swamp, or open water, do not break the wooded area up into separate polygons. Digitize a single area by following the outermost extent of the green tint.

        070 0102 Scrub

Scrub areas are shown by symbols 603(A), 154.1(B), 554.1(C), or 2402.05(D).

        070 0103 Orchard or plantation

These features are shown by symbols 601(A), 155.1(B), 555.1(C), or 2402.03(D). Plantings of trees that are called groves are collected using this code.

        070 0104 Vineyard

Vineyards are shown by symbols 602(A), 156.1(B), 556.1(C), or 2402.04(D).

        070 0105 Scattered trees

Scattered trees are shown by symbol 553.1(C).

        070 0106 Void area

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