VAST Challenge 2017 - Mystery at the Wildlife Preserve
ISSS608 Visual Analytics and Applications - Individual Assignment
Prepared by Chua Gim Hong
Contents
Background
Mistford is a mid-size city located to the southwest of a large nature preserve. The city has a small industrial area with four light-manufacturing endeavors. Mitch Vogel is a post-doc student studying ornithology at Mistford College and has been discovering signs that the number of nesting pairs of the Rose-Crested Blue Pipit, a popular local bird due to its attractive plumage and pleasant songs, is decreasing! The decrease is sufficiently significant that the Pangera Ornithology Conservation Society is sponsoring Mitch to undertake additional studies to identify the possible reasons. Mitch is gaining access to several datasets that may help him in his work, and he has asked you (and your colleagues) as experts in visual analytics to help him analyze these datasets.

Mini-Challenge 3
There were signs that the number of nesting pairs of the Rose-Crested Blue Pipit is decreasing. Mitch Vogel faced difficulty trying to assess the extent of the possible problem contributed to the downfall of the poor Rose-crested Blue Pipit bird because:
a. While he was able to get around some of the nature preserve to study the bird, he was not able to cover the entire preserve with a car or on foot but because of the terrain and the vegetation.
b. Drones and air vehicles would scare the birds.

Dataset
The multi-spectral dataset files from the National Space Service show the same piece of the Lekagul Preserve as imaged by a satellite multispectral sensor that measures in six different bands (B1 – B6) over a few years in the following format:
• TIF files which are 8-bit, 6-band files with 651 rows and columns. Bands 1-6 are ordered by wavelength (shortest to longest wavelengths) B1=blue, B2=green, B3=red, B4=near-infrared, B5= short-wave infrared (SWIR) 1 and B6= short-wave infrared (SWIR) 2.
• ASCII files which are in comma-delimited format where each record is the pixel value for each band at that X, Y location.
Note: X, Y origin is the upper left corner of the image. The X, Y locations are relative to the image itself and not a geo-coordinate on Earth. So, X=0, Y=0 refers to the pixel in the upper left corner of the image. Similarly, the bottom right pixel is X=650, Y=650.
The sensor is a sensitive scientific instrument and the resulting images are optimized for measurement and are not simply “pictures”.
