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.

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 Open Context's 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.
