Geospatial Data Visualization in 4D

1. Abstract

This research details a WebGL-based raster tile renderer designed to visualize temporal geographic datasets. We present a dynamic multi-spectral overlay pipeline for city-scale routing and agricultural changes.

2. Introduction

Visualizing municipal growth, traffic patterns, and vegetation indexes requires processing multidimensional datasets. Traditional GIS systems suffer from long rendering latency when handling time-series raster overlays on mobile browsers.

3. Pipeline Architecture

We develop a spatial-temporal indexing schema that groups raster data into WebGL textures. By running raster interpolation shaders directly in GPU memory, the client renders multi-spectral timelines dynamically. Road networks are handled via custom vector tile routing graphs compiled in Rust.

4. Performance and Implementation

The 4D rendering pipeline achieves smooth 60 FPS performance on standard mobile browsers, reducing spatial load times by 72% compared to traditional leaf/tile caching schemes. The model successfully powers our SkyNet GIS agricultural monitors.
