INTRODUCTION

High resolution multi-spectral satellite imagery covering the entire Earth is available online, with new imagery acquired on a weekly basis (Landsat, Sentinel).
Using specialised software, Weddin Mapping Solutions can process and display this raw data, along with other spatial data-sets (NSW Spatial Data Catalogue, Geoscience AustraliaBureau of Meteorology), to observe the current state of the landscape, as well as changes over time, and display this information in detailed maps.
To demonstrate applications of this data, Weddin Mapping Solutions has created a range of customised maps, including interactive web maps, that feature regularly updated imagery of the WEDDIN LGA and surrounding areas including  COWRA, FORBES, YOUNG and WEST WYALONG.

NDVI & AGRICULTURE

  • Satellite imagery and its use in modern farming systems is becoming increasingly common.
  • The following collections of maps and images aim to show how one particular use, normalised difference vegetation index (NDVI) imagery, can be interpreted and applied to agriculture.

AN INTRODUCTION TO MULTI-SPECTRAL IMAGERY

Modern satellites are capable of capturing multi-spectral images – which include visible bands of light (red, green, blue) as well as bands beyond the visible spectrum (near infra-red, shortwave infra-red, etc). Different combinations of these bands create images that highlight certain features in the landscape – such as variations in vegetation, moisture and rock type. A series of maps featuring different band combinations of satellite imagery of the Weddin Shire from throughout the year 2015 has been created.
