Genomic interval operations on Pandas DataFrames
BBoxDB is a scalable, highly available, and distributed data store for multi-dimensional big data. The software supports operations like multi-dimensional range queries and spatial joins. In addition, data streams are supported.
A fast library for spatial joining and merging data in JavaScript 🚀
An example of how to join point to polygon data with geopandas and Python
RTDL is a research system for writing and running non-graphical ray-tracing programs across Embree, OptiX, and Vulkan.
Spatial joining with a map reduce program on top of Apache Spark using the Apache Sedona spatial extension
How much of California's public wildfire damage-inspection record set can be attributed to a published electric service territory, and how much cannot. 37.9% of records fall inside more than one published boundary. Every rate carries its denominator and a confidence interval; no utility is ranked. Unofficial.
Polygon & GMR 1 — QGIS plugin: join a polygon layer with an Excel file (GMR). Reads the real column headers of every sheet, matches on a chosen join field, and outputs only the matching polygons with their attribute table enriched with the Excel columns.
Vector spatial analysis of vape-store proximity to Christchurch schools using CRS validation, buffers, spatial joins, and nearest distances.
An enhanced intersect operation with sjoin in GeoPandas
An advanced multi-scalar geovisualisation of the UK's renewable energy landscape. This project maps the "Renewable Gap" by integrating the Q4 2025 REPD database with 33,000+ LSOA boundaries, featuring a drill-down dashboard to analyze operational reality vs. the planning pipeline.
