Leaflet.pub is a web application designed for creating and sharing interactive, media-rich documents. Users can embed various content types, including maps, charts, 3D models, and videos, directly within their documents. These documents are easily shareable via a public URL and offer a flexible layout that adapts to different screen sizes. The platform aims to be a user-friendly alternative to traditional document creation tools, allowing anyone to build engaging presentations or reports without requiring coding skills.
MapTCHA is an open-source CAPTCHA that leverages user interaction to improve OpenStreetMap data. Instead of deciphering distorted text or identifying images, users solve challenges related to map features, like identifying missing house numbers or classifying road types. This process simultaneously verifies the user and contributes valuable data back to OpenStreetMap, making it a mutually beneficial system. The project aims to be a privacy-respecting alternative to commercial CAPTCHA services, keeping user contributions within the open-source ecosystem.
HN commenters generally express enthusiasm for MapTCHA, praising its dual purpose of verifying users and improving OpenStreetMap data. Several suggest potential improvements, such as adding house number verification and integrating with other OSM editing tools like iD and JOSM. Some raise concerns about the potential for automated attacks or manipulation of the CAPTCHA, and question whether the tasks are genuinely useful contributions to OSM. Others discuss alternative CAPTCHA methods and the general challenges of balancing usability and security. A few commenters share their experiences with existing OSM editing tools and processes, highlighting the existing challenges related to vandalism and data quality. One commenter points out the potential privacy implications of using street-level imagery.
Jesse van der Pluijm has created a web-based 3D global topography explorer using CesiumJS and elevation data from Mapzen. The interactive globe allows users to smoothly zoom and pan around the world, viewing terrain in realistic detail. It features adjustable vertical exaggeration to emphasize mountainous regions and an optional atmospheric scattering effect for added realism. The project is open-source and available on GitHub.
HN users generally praised the 3D topography explorer for its smoothness, intuitive interface, and interesting data visualization. Several commenters appreciated the technical details provided by the creator, specifically around data sourcing and rendering techniques. Some suggested potential improvements, including adding features like location search, elevation profiles, and different map projections. Others discussed the challenges of representing elevation accurately on a globe and the trade-offs involved in different visualization methods. A few users shared their enjoyment in exploring specific locations using the tool.
