FGDC Texture Patterns Reference

Overview

This document lists all texture patterns available in FGDC_TEXTURES_OPTIONS from @welldot/core. These codes follow the FGDC (Federal Geographic Data Committee) digital cartographic standard for geologic map symbolization.

Use a code value in the texture field of a Lithology record to assign a pattern to a depth interval.

import { FGDC_TEXTURES_OPTIONS } from '@welldot/core';

// Find a texture by code
const limestone = FGDC_TEXTURES_OPTIONS.find(t => t.code === 627);
// { code: 627, label: 'Limestone' }

// Filter to only textures with a rendered image
const available = FGDC_TEXTURES_OPTIONS.filter(t => !t.pending);

Texture availability: Some entries carry pending: true, meaning the SVG pattern image has not been implemented yet. Textures without this flag are fully rendered and ready to use. The flag is transitional and will be removed once all patterns are complete.

Currently 120 of 282 textures are available: all of Series 600 (84) and Series 700 (33), plus codes 120, 123, and 132 from Series 100.

The patterns are grouped by FGDC series below. Each table lists the code and label of every pattern, and the summary at the end gives the available and pending counts per series.

Series 100 — Surficial Patterns

Series 200 — Sedimentary Patterns

All entries in this series are pending (no SVG images implemented yet).

Series 300 — Igneous Patterns

All entries in this series are pending (no SVG images implemented yet).

Series 400 — Miscellaneous and Metamorphic Patterns

All entries in this series are pending (no SVG images implemented yet).

Series 500 — Glacial and Periglacial Patterns

All entries in this series are pending (no SVG images implemented yet).

Series 600 — Sedimentary Lithology Patterns

These are the most commonly used codes for well lithology logging. They represent specific rock and sediment types encountered in boreholes.

Series 700 — Metamorphic and Igneous Lithology Patterns
