Terrain Model Generation and Analysis

Introduction

In this year’s Google Summer of Code program, I developed a module called terrainTools. This project is based on the 52°North Triturus library, which is extremely powerful and provides a lot of functionalities in the field of 3D geovisualization.

Most terrain based visualization applications in today’s world have different file formats that are difficult to export. In order to solve that problem, we have created terrainTools. Here, all visualization algorithms can be accessed from a web browser and can be shared seamlessly using Google’s services. This project is one of the few cloud based solutions to visualize terrain datasets with a three-dimensional viewpoint.

In this project, I demonstrate how Triturus can be used in day to day terrain applications. Using terrainTools, we can create elevation grids, visualize flooding applications, generate cross-section for a terrain and even calculate difference models!

Let’s get started!

EnviroCar Visual Analytics – Final Report

Introduction

The enviroCar project allows users to collect and share their driving statistics via an OBD sensor coupled with an Android app. The app collects car data and pushes the data to a server with a stateless REST API that exposes this data. The enviroCar project’s website, which is currently built in PHP, makes use of this API endpoint to provide a dashboard experience to a user for vehicular track analysis. The project’s objective is to rebuild the website as a SPA (Single Page Application) with the AngularJS framework. This could also serve as the starting point for the next generation website. The previous blog post contains the work done till the mid term of this project. The upcoming sections of this blog post discuss further work done and problems faced.

The main project repository can be found here https://github.com/enviroCar/enviroCar-website-ng

smle /ˈsmaɪ.li/ is one of 52°North’s new developments. It is a SensorML editor based on TypeScript and Angular 2. The implementation of this editor  started earlier this year within the projects NeXOS and FixO3. The idea of the Google Summer of Code activity was to enrich the editor with further functionality and input fields.
As the Google Summer of Code 2016 comes to an end, we can see the results of the 13 week development period and compare it with the first plan described in the introductory blog post and with the interim results from the mid-term blog post. (more…)

Terrain Model Generation and Analysis – Midterm

Introduction

The 52°North Triturus library is extremely powerful and provides a lot of functionalities in the field of 3D geovisualization. This library is used in a lot of projects such as 52°North terrainServer and 52°North WorldViz. Currently, the terrainServer offers web-based services providing perspective terrain views. The project’s goal is to extend terrain model generation and analysis to practical scenarios in which it would be desirable to have web-based access to tools (e.g., difference surfaces, mass calculations, inclination analysis) and to model generation functions. These should use 52°North Triturus library. In the Google Summer of Code 2016 program, we shall try to achieve web-based access for some of these tools. This new module has been named ‘terrainTools’ and will be a standalone project. (more…)
