Eigentlich war's bloss ein kleiner Spass, zusammengeklopft an einem verregneten Dezembernachmittag: Meine aus lauter Emojis bestehende Karte der Schweiz namens «Confœderatio Emojica».

Weil opendata.swiss, das Datenportal der Schweizer Behörden, stets daran interessiert ist, was Bastler mit den offenen Daten von Bund und Kantonen so alles anstellen, wurde meine Emoji-Karte nun als Showcase publiziert.

🛰️🇫🇷 Les cartes “restrictions drone” en France sont souvent difficiles à lire (capture 1).

Avec #VigiDrone (capture 2) : vert = tu peux voler en catégorie Open, rouge = interdit.

Basé sur de la donnée officielle SIA (zones UAS / ED-269) + fonds IGN / Géoservices + open data.

If I had a dollar every time someone said the haversine formula was "good enough", I could probably have a mediocre meal out. Vincenty all the time.

Konferenztage an der Küste 🌊

Die GI-Fachgruppe Umweltinformationssysteme lädt nach #SchleswigHolstein ein! Im Fokus stehen aktuelle Verfahren zur Beobachtung und Analyse der Umwelt.

Themen wie #GeoData, Sensornetzwerke oder #DigitalTwins sollen insbesondere aus Anwendungssicht kritisch diskutiert werden: Wie tragen sie zum Schutz von Küsten oder der Biodiversität bei?

📌 Tönning & online
📅 10.–12.6.

Alle Infos zum #CfP oder zur kostenlosen Teilnahme: https://ak-uis.de/

SayWhere Geocoding System: Human-Memorable Geographic Coordinates

This document specifies SayWhere, an open-source system for encoding geographic coordinates (latitude, longitude, and optional altitude) into human-memorable word phrases and decoding them back to coordinates. The system provides deterministic, reversible encoding with two-layer error detection (per-word parity and optional terminal word-phrase checksum) and supports three-dimensional positioning for multi-level structures. SayWhere introduces hierarchical variable- length phrases with true prefix relationships, enabling precision scaling from regional (1 word) to meter-level accuracy (6 words). The system uses the Bitcoin Improvement Proposal 39 (BIP-39) mnemonic wordlist for multilingual support and geohash spatial indexing for efficient location encoding.
