Turf Concave

The turf-concave icon represents a geographic information system (GIS) concept used to create a concave hull around a set of features. It is often used in spatial analysis and geometric operations. The turf-concave function is used to compute the concave hull coordinates.

In real-world applications, the turf-concave icon appears in software such as ArcGIS, QGIS, and GRASS GIS, which are used for spatial analysis and mapping. These tools are widely used in various industries, including urban planning, environmental monitoring, and natural resource management.

From a UX perspective, the turf-concave icon communicates the idea of creating a concave hull. It helps users understand the functionality of performing geometric operations and analyzing spatial data. The icon is often used in conjunction with other GIS tools to provide a comprehensive analysis of spatial data.

Turf Concave is one of 30 icons in GeoGlyphs, made by Sam Matthews and released under MIT. It is drawn on a 100 × 100 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds TurfConcaveIcon to components/icons/geo-turf-concave.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed TurfConcaveIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Turf Concave icon, or any of 30 GeoGlyphs icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 100 × 100 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Turf Concave", so screen readers say what it does.

Yes. TurfConcaveIcon passes every SVG prop to the svg element, so <TurfConcaveIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming GeoGlyphs, Sam Matthews and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are map, analysis, GIS, geometric, spatial and operations. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Turf Concave in another set.

GeoGlyphs draws many icons in several styles: Line next to the default. Open the library and pick a style above the grid to see Turf Concave's siblings in it.
