What FEMA flood zone designations mean for development feasibility, insurance, construction costs, and lender requirements.

How SSURGO soil surveys predict agricultural productivity and construction costs before you close on land.

This repo provides an exhaustive look and comparison of all the history of geospatial software and gets non-spatial software engineers up-to-speed in geospatial technologies and concepts in this ne...

This package is an implementation of the geoviz javascript library. can be used to create a wide range of interactive, zoomable vector maps, taking advantage of d3’s many features: proportional symbols, pictograms, typologies, choropleth maps, spikes, tiles, Dorling cartograms, etc. It can also be used to create pretty static vectorial maps in SVG format, suitable for editorial cartography.

Shiny-style authoring, stateless API deployment. Build the UI in R with bslib, compile it to a static asset, and serve it plus JSON routes with plumber2.

This tutorial walks through a simple point-and-click workflow starting from a GitHub repository with an app.R and Dockerfile and then shows how to connect it to Cloud Run.

Discover the essential layers of testing for robust R packages: unit tests, acceptance tests, code coverage, and mutation testing.

In this workshop in partnership with RLadies BA, participants learned how to build reproducible research workflows with R and Quarto, integrating code, results, figures, and narrative into a single document for publishing manuscripts, reports, presentations, and more.

DuckLake delivers advanced data lake features without traditional lakehouse complexity by using Parquet files and your SQL database. It's an open, standalone format from the DuckDB team.

We released Quack on May 12, 2026. Read the announcement blog post! The Quack extension turns a DuckDB instance into a server that other DuckDB instances (clients) can connect to over HTTP. This page covers the protocol at a glance and walks through basic usage on both sides of the wire. For the full list of functions, settings, and logging knobs, see the Reference. For configuring TLS and authentication / authorization, see Security. For user guides, see Guides. Warning Quack is under active development and the protocol, function names, settings, and defaults are still subject to change. This page documents…

The Quack protocol turns DuckDB into a client-server database.

How to download data using R

A minimal columnar query engine with lazy execution on datasets larger than RAM. Provides 'dplyr'-like verbs (filter(), select(), mutate(), group_by(), summarise(), joins, window functions) and common aggregations (n(), sum(), mean(), min(), max(), sd(), first(), last()) backed by a pure C11 pull-based execution engine and a custom on-disk format ('.vtr'). Reads and writes 'GeoTIFF' (including tiled and 'BigTIFF' layouts) and a tiled raster format ('.vec') with overview pyramids and time cubes for larger-than-RAM raster data. Streams vector operations (spatial transforms, point-in-polygon and nearest-feature joins including a two-sided grid-partitioned join, select-by-location, clip, erase, dissolve, 'rasterization', 'polygonization', and contouring) through 'sf', and runs raster operations (zonal statistics, focal windows, terrain derivatives, resample or 'reproject' warp, polygon masking, map algebra, and 'mosaicking') in native C or over the tiled '.vec' format, one batch or tile at a time for data larger than RAM.

All my AI conversations were trapped inside various bot models, and my PKM had no access to them. Here is a converter that exports your chat history to local files for your knowledge management system.

Your AI conversations contain decisions, solutions, and research that took real time to generate. Backing them up protects against account loss, platform changes, and the natural drift of conversation history. This guide covers backup options for every major AI platform.

Keiran Flynn is the founder of LLMnesia, a local-first Chrome extension that indexes and searches AI conversations across ChatGPT, Claude, Gemini, and other platforms.

Perplexity conversation history grows quickly with research threads, Pages, and Spaces. This guide covers every available method for organising your Perplexity history — from Library features to external tools — so you can find past research when you need it.
