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…)

Statistics for OGC Web services – Midterm report

Posted in Communities, GSoC, Sensor Web

Introduction

The project goal is to collect statistics about how the clients use the SOS and WPS deployments. The data is collected in an Elasticsearch database. If you would like to read more about this proposition, please read the project’s first blog post.

Status

After 4 weeks of development, a new statistics module has been integrated into the SOS 4.x project. The following features are currently available:

  • Core, Enhanced, Transactional and Result Handling OGC SOS 2.0 requests are listened for and their parameters are persisted into the Elasticsearch.
  • The ExceptionEvents are also caught and loaded into Elasticsearch.
  • The client’s source IP address is stored in the Elasticsearch database as a geo-location address. The transformation is provided by the Maxmind’s GeoLite2 databases. The geo-location information can be visualized on a Kibana tile-map.
  • All the persisted information could be visualized and queried in Kibana.
