ifgicopter – Microcopter as a sensor platform for environmental monitoring
Matthes Rieke, Christian Knoth
ITC Visit @ ifgi, Münster, 13.09.2010
![Page 2: Ifgicopter presentation @ itc visit](https://reader034.vdocuments.us/reader034/viewer/2022042606/54885582b479590a0d8b5671/html5/thumbnails/2.jpg)

Motivation
● Set of problems● Creation of orthophotos of small areas of interest
– financial and logistical complex venture– areas of interest which are hard to reach
● Measurements of climate
phenomena– are not available in the
desired dose or are out of
date– Hard to reach →

Motivation
● Aims of the project
1.Individual creation of (infrared) orthophotos of small areas of interest– sustainable environmental monitoring
● vegetation assesement● terrain acquisition● Hi-res images → temporary change of unreachable areas of
interest
2.Highly flexible usage of a flying sensor platform to gather climate phenomena measurements– No long preliminary work needed

Team and fields of work
● Fields of work● Planning software (Geoinformatics)● Communication framework (Geoinformatics)● Creation of orthophotos (Geography)● Analysation of climate phenomena (landscape economy)● DGPS services (Geoinformatics)

The ifgicopter
● Basis is a building kit by www.mikrokopter.de
● GPS modules already integrated
![Page 6: Ifgicopter presentation @ itc visit](https://reader034.vdocuments.us/reader034/viewer/2022042606/54885582b479590a0d8b5671/html5/thumbnails/6.jpg)

Communication
● Communication in real-time● Copter uses a Wi232 module to periodly send data
(HF at 868 Mhz → no license needed in germany)● Gathering of GPS position and many other useful
data
● Uplink● Send GPS waypoints to the copter

Application 1: Orthophotography
● First application – Creation of Orthophotos● Flightroute planning software
![Page 8: Ifgicopter presentation @ itc visit](https://reader034.vdocuments.us/reader034/viewer/2022042606/54885582b479590a0d8b5671/html5/thumbnails/8.jpg)

Application 1: Orthophotography
● First application – Creation of Orthophotos

http://swsl.uni-muenster.de/research/ifgicopter 9
Application 1: Orthophotography
● Photographs need to overlap about 60% with their neighbours → automatic calculation of waypoints following this requirement
● Planning software is capable of creating a flight route which covers a user-defined area of interest (bounding box, polygon, etc.)

Application 1: Orthophotography
● The camera: Panasonic LUMIX LX3 – UV+VIS+IR
● Internal band-elimination filter removed → photographs in VIS and NIR possible with an additional filter

Application 2: real-time data gathering
● Second application – real-time data gathering● Two-tier architecture
– Transmission of measurements from copter to a groundstation
– Transformation into standardized data formats (OGC: Observation & Measurements) and integration into the Sensor Web

Application 2: real-time data gathering
● Realization using a two-tier framework– Input in proprietary formats– Output as interoperable data
● Why framework?● Not restricted to ifgicopter platform → other sensor
platforms easily integrable● Connection to web services made simple
