The goal of this Google Summer of Code project is to extend the 52°North WPS‘s functionality by adding Ilwis-Objects as a processing backend. The 52°North  currently supports several different backends, such as R or GRASS. The introductory blog post can be found here.

The current status of the project can be seen in the following diagram.

enviroCar Light – Mid Term Blog Post

Introduction

The collection of driving data using the mobile application for enviroCar requires a number of manual user interactions. This is unpleasant and tedious over the long run and poses a major obstacle for using the app regularly. To tackle these problems, the enviroCar light project aims to enhance the usability of the enviroCar application by simplifying and automating the workflow of collecting driving data in order to achieve more regular contributions of users.

Another drawback of the mobile application is the implementation style and the rather outdated technologies and libraries used. This makes it hard for external developers to contribute to the enviroCar project. For this reason, another aim of the project is to update the enviroCar app to current standards of Android-related development paradigms. (more…)

Social Driving Stats – Midterm Blog

Introduction

The goal of the project “Social Driving Stats” is to develop a mechanism for sharing tracks and user details on social media services such as Facebook, Twitter and Google plus. By avoiding messages that only contain plain text, we aim to share the statistics and details in a catchy manner, which drives social media users to use the enviroCar service. Thereby, one challenge is how to deal with the various restrictions using the social media APIs provided. (more…)

SPARQL endpoint and Interoperability of enviroCar data : Midterm Report

Introduction

The enviroCar SPARQL endpoint is a feature that enables the enviroCar data to be queried in RDF. This feature creates an open endpoint for crawlers and other bots and allows them to crawl the data and let the data be part of the LOD cloud. With the enviroCar server’s current architecture, it is possible to query the data by converting the entities on the fly into RDF when a particular kind of request is made. Please find a more detailed description about the project’s evolution on the SPARQL EndPoint wiki page.

Over the past few weeks, I’ve embarked on the task of moving the data from mongoDB (the database of choice for the enviroCar server) and cloning the entire database content to a raw data type, independent of database formats. My task also involved solving the problem of trying to remove the tight coupling of frameworks with the generation and retrieval of data. This would make more data interchanging processes more commonly known as ETL processes. This is a design for future implementation and can be found here.

Introduction

The aim of the WorldViz project is to set up thematic maps showing connections or dependencies between different spatial features. We have had several highly productive and interesting meetings during this first four weeks of this project. Currently, three of us are involved in the project – Professor Dr.Benno Schmidt, Christian Danowski (both Hochschule Bochum) and Adhitya Kamakshidasan (National Institute of Technology, Nagpur).

There are various components to our WorldViz Project and I shall to mention each one of them in detail below. (more…)
