OpenWLANMap: Open Database of WLAN Locations

Slashdot discusses a story named OpenWLANMap: Free WLAN-Based GPS Replacement. I don't think we mentioned OpenWLANMap before, but we did mention MAC address mapping. Here's the OpenWLANMap website.

The Slashdot summary: "There are a couple of commercial products which can tell you where you are by the MAC addresses of access points in your neighbourhood. E.g. the iphone uses a system like this. There's now an open offering for this: OpenWLANMap. With this website, you can enter your access point mac address with your GPS location and then others can use that to navigate. There is also an app for your mobile which automatically enters this data, and you can upload data from e.g. Airomap and other wardriving applications."

  • We love numbers right? At the beginning of last month was a user test between JTS Union VS ArcGIS Dissolve, result: 25 seconds vs 1.5 second in favor of the open source JTS
  • Probably of interest to some of you, an entry on Optimizing OpenLayers for Mobile Applications
  • DM shares an article named [U.S.] FedGeoDay: Advocating for Open Source, the summary: "FedGeoDay, held in Washington, D.C. this past week, can best be described as an advocacy forum for open source geospatial technology and data. Some of the leading organizations, government agencies and companies invested in open source tech sponsored the conference."
  • Another article from the same source, The Arches Project: Turning Open Source GIS into a Heritage Inventory and Management System
  • And a last article from DM, Palantir: An Open Source Development Success Story, which is really about leveraging PostGIS, the summary: "In late Palantir launched Gotham, a new geospatial and comprehensive analytics platform designed to meet the challenges of their vast array of customers. This article provides more information on Gotham that enables data integration, search and discovery, knowledge management, secure collaboration, and algorithmic analysis across a wide variety of data sources."

OpenMeteoData - Making Meteorological Data Available to Anyone

Via OpenWeatherMap I learned about the OpenMeteoData, that has the aim to make meteorological data available for everyone.

From the website: "

What is OpenMeteoData?

  • OpenMeteoData is an non-profit organization. We aim to make meteorological data available for everyone. We are now building our own supercomputer to calculate open weather forecasts. We run the Weather Research and Forecast (WRF) model. This is state of the art numerical weather prediction tool, developed by several major universities and US governmental agencies.


  • In most Europeans countries, weather data is not freely available. You have to pay hundreds of thousand euros to get access to raw model outputs.

Who can use the data?

  • Everyone. It's free. That's just like Wikipedia or OpenStreetMap. [...] We plan to release all of the data under Open Database Licence (ODbL). That means the data is free, and it can be used for both personal and commercial projects.

When will it be available?

  • If everything goes right, a first preview is expected for March."
