I couldn't find any specific information on creating a Gamecocks background using vector tiles in high definition (HD). However, I can suggest a possible solution using @mapbox/vector-tile and GeoJSON data.

To create an HD background, you'll need to use a higher resolution version of the Gamecocks GeoJSON data. You can do this by scaling up the original data or by using a higher-resolution tileset.

Here's a brief snippet to get you started:

import { VectorTile } from '@mapbox/vector-tile';

// Load the Gamecocks HD GeoJSON data
const geojson = require('./gamecocks-hd-geojson.json');

// Create a vector tile layer with the HD GeoJSON data
const layer = new VectorTile(geojson);

// Use the vector tile layer to create your background

You'll need to replace ./gamecocks-hd-geojson.json with the actual path to your Gamecocks HD GeoJSON data file.

Keep in mind that creating an HD background using vector tiles can be computationally intensive, especially if you're working with large datasets. You may want to consider optimizing your code or using a more efficient library to achieve the desired performance.

If you have any further questions or need more specific guidance on how to create an HD Gamecocks background using vector tiles, feel free to ask!
