Parsing NOAA sources 2 Comments

For those that prefer Ruby over Java, I have good news: Sensorpedia scripts can now be written using JRuby. It uses the same API as the Java interface (both a positive and negative), so now you’ll be able to parse data sources using the convenience of Ruby regular expressions. In order to test this, I [...]

What is a table anyway? Comment

In a previous post, I did a quick analysis of the numeric content of webpages. To no one’s great surprise, web pages containing sensor data often contained a greater amount of numeric data. As nice as it would be to leave it at that, it turns out that analysis is a bit too simple for [...]

Virtual Sensor Nodes Comment

In a previous blog post, I discussed the idea of a virtual scripting layer that operated over the Sensorpedia data sources. Each data source, instead of just exposing links to data, will also expose a data-oriented programming interface. Users will be able to write and upload scripts that can transform raw data and communicate with [...]

Programming tools for Sensorpedia Comment

Besides automatically discovering new sensor data, I’m also interested in what to do after we get the data into Sensorpedia. Right now users interact with Sensorpedia via the web mapping tool. Users type in a search term that matches the title, textual description, or user-supplied tags and generates a list of geo-indexed placemarkers. This is [...]

Discovering new sensor data Comment

While David has been working hard on Sensorpedia’s infrastructure, I’ve been thinking about different ways to automate the process of identifying, tagging, and extracting sensor data from the internet. This would be handy for several reasons. 1) we wouldn’t have to spend valuable human time performing a relatively mundane task and 2) having a sensor [...]
