Caching for Sensor Web REST-API

There are only two hard things in Computer Science: cache invalidation and naming things.

Phil Karlton

Caching is a common technique to improve the response time of a data source. A cache is a temporary storage for a most often acquired data. Caching is widely used in a proxying software such as Squid. The caching of network responses can provide a huge improvement to the response time. The latency of a network resource is much more greater than of a memory or a disk resource [Fig.1]. That’s why the caching is a “must-have” feature of network proxies.

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!
