Hands-on Day

There will be a Hands-on Day for ‘doers’, ‘dabblers’, and ‘would-be-dabblers’ following the UAS4RS Conference 2017 on Friday the 26th May 2017. Please note that this event needs to be booked separately.

Friday 26 May
08:15 – 08:30     Bus to 4 Elizabeth St, Hobart (leaves from: Churchill Avenue, TUU bus stop, Sandy Bay)
08:30 – 09:15     Bus to Home Hill Winery, Ranelagh (leaves from: 4 Elizabeth St, Hobart)
09:15 – 11:45      Home Hill Landslide: Flight and data collection demonstrations (Barrel room if rainy)
12:00 – 13:00      Lunch
13:00 – 13:45      Bus to UTAS, Sandy Bay
14:00 – 15:30      Beginner I (Room Geo.227) Advanced I (Room Geo.229)
15:30 – 16:00      Coffee
16:00- 17:30       Beginner II (Room Geo.227) Advanced II (Room Geo.229)

The day will be spilt into two parts, the first half of the day will be spent in the field at the Home Hill Winery about 30 mins from Hobart (bus transport will be provided). The site is of interest as there is a large landslide adjacent to the vineyard which has been mapped with a UAS annually for seven years now.

On site we will spend time going through the practicalities of collecting UAS mapping data.

This will include discussion and demonstration of:

  • the use of ground control points
  • spectral calibration targets
  • spectral validation data
  • flight planning

Data collection will then be demonstrated with a range of our platforms and sensors.

Following a pleasant lunch on site at the vineyard we will head back to the University of Tasmania. The afternoon will be spent discussing and demonstrating methods for processing the types of data collected. There will be two sessions, one for beginners and one for advanced data analysis.

Beginners: This session will take the group through a fully worked Photoscan project that will process data collected at the Homehill landslide site during a previous visit. Each step of the process will be explained and demonstrated in detail and the underlying algorithms will be explained. It will include how to correctly use Ground Control Points for both improving accuracy of the product an assessing the overall error of the results. During the process, the group will learn little tricks a tips to make their life easier during future Photoscan projects. Questions and interaction during the demonstration will be strongly encourage, if time permits we will finish with some examples of multispectral and thermal imagery Photoscan projects, as well as discussing other software such as Pix-4D.

Advanced: This session will provide an introduction to: (1) radiometric correction using spectral calibration targets and an empirical line correction method; and (2) object-based image analysis of UAS image data. After the introduction, there will be a hands-on session using the eCognition Developer software to perform an empirical line correction and to undertake land-cover classification using a rule set in eCognition to demonstrate how spectral, height and context information can be used to improve your classification results. People attending this hands-on session will be able to follow a demonstration of the object-based image analysis workflow while undertaking the individual rule set steps themselves using the eCognition Developer software.

Option 1: Come to this session to follow the demonstration and learn how to convert your UAS image data into land-cover maps using object-based image analysis.

Option 2: Bring your own laptop with the eCogntion Developer Trial version installed (download from: http://www.ecognition.com/free-trial) to participate in this hands-on session and process multi-spectral UAS image data yourself using object-based image analysis and a provided rule set.
