Integrating LoRaWAN Sensors with the OGC SensorWeb

In this year’s Student Innovation Challenge held by 52°North, I participated with a software project aiming to extend the open sensor web with a new way to transmit sensor observations. The 8-week challenge under the topic ‘Bridging IoT and Sensor Web Applications’ enabled me to deepen my knowledge on LoRaWAN connected sensors while contributing to the Sensor Web community. My project’s deliverable is an integration between TheThingsNetwork and the OGC SensorWeb, adding the missing component to a full open source stack for LoRaWAN connected sensing platforms. (more…)

Contextual Button – Measuring User Interactions with a Contextual One-Button-Interface

This year’s 52° North Student Innovation Challenge focused on connecting the Internet of Things with Sensor Web technologies. My entry into the challenge was inspired by the Amazon Dash button, a small internet enabled device that allows Amazon customers to order refills for their consumable goods (e.g. razor blades, detergent, etc.). When it is pressed, it connects to Amazon and places an order for the respective item.
What fascinates me is the idea of replacing the process of deliberately going online with a physical action that is directly integrated in the user’s current context. For example, when the user has just used the last of their detergent, they can directly press the button attached to the washing machine to order a refill. The whole interaction takes place in the context of washing clothes. (more…)

OSGeo-Live 11.0 has been released! It has been a major reboot, with a refocus on leading applications and emphasis on quality over quantity. Less mature parts of the projects have been dropped with a targeted focus placed on upgrading and improving documentation. There is now support for isohybrid ISO images with UEFI

52°North’s latest SOS version is now available on OSGeo-Live! (more…)

GSoC2017 - M.M.Don

My experience with the GSoC 2017 project “Simple Features for Protobuf and others” came to an end by presenting my results at the Geospatial Sensor Webs Conference 2017. It was really pleasing to see that a majority of the audience was really interested in the project outcome and eager to see it progress in the future. (more…)

Simple Features for protobuf and others – Mid Term Blog Post

Introduction

The core idea of my GSoC 2017 project “Simple Features for protobuf and others” is to define and implement a serialization API for spatial vector data, which will transparently serialize geometries based on the Simple Feature specification using Protobuf into binary encoding. The Simple Feature Access Specification is a common standard that is widely used in geoinformatics for exchanging spatial features. This serialization API also supports decoding serialized binary data into prefered output models such as JTS and others. Protocol Buffers is used as the primary serialization framework. Other serialization frameworks, such as Avro, are being considered as well. I am currently implementing serializing support for raster data into the API, where it will utilize raster data formats, such as GeoTIFF, and modeling libraries, such as GeoTools.
