title: Using Cesium for display of remote parquet.
title: Using Cesium for geospatial visualization of remote parquet data
categories: [parquet, spatial, recipe]
---

This page renders points from an iSamples parquet file on cesium using point primitives.
<p>One key development of the iSamples project centers on the demonstration of low-cost, simplified, and more sustainable approaches to access, analyze and visualize scientific data. Rather than relying upon elaborate and costly server-side infrastructure, iSamples demonstrates how open source technologies like parquet and DuckDB-WASM can streamline cheaper and faster approaches to interacting with geospatial data.</p>

<p>This page demonstrates how geospatial data can be dynamically accessed from a remote parquet file in cloud storage. The page uses Cesium for browser visualization of these spatial data on a 3D global map. The data in this demonstration comes from <a href="https://opencontext.org/" target="_blank">Open Context's</a> export of specimen (archaeological artifact and ecofact) records for iSamples. However, this demonstration can also work with any other iSamples compliant parquet data source made publicly accessible on the Web.</p>
