# Leaflet.TileLayer.GLOperations

Custom Leaflet TileLayer using WebGL to do operations on and colorize floating-point pixels

## Resources

* [Demo](https://equinor.github.io/leaflet.tilelayer.gloperations/)

* [Wiki](https://github.com/equinor/leaflet.tilelayer.gloperations/wiki)

* [Changelog](https://github.com/equinor/leaflet.tilelayer.gloperations/blob/master/CHANGELOG.md)

## Features

- GPU rendering

- A simple declarative API

- A small configuration language for describing how to colorize pixels

  - Interpolated color scale

  - Sentinel values with optional labels

- Raw float pixel value(s) provided to mouse event handlers

- Hillshading

- Contours

- Animated per-pixel transitions when changing URL and/or colormaps

- Load multiple tile layers, do operations on them and return result layer:

  - Difference between two tile layers

  - Analysis of multiple tile layers (supports 1-6 layers currently). Filter values and use a multiplier for each layer.

  - Return pixel values for both input and result layers
