Guide for working with aerial images

August 24th, 2015, Published in Articles: PositionIT



Satellites, aircraft, and unmanned aerial systems (UAS) collect imagery that can be displayed and analysed within a geographic information system (GIS) to extract important information. To familiarise GIS professionals and students with the advanced earth imaging technologies available, Esri has published Essential Earth Imaging for GIS. The book is a field guide to earth imaging, providing guidance to efficiently and effectively display, manipulate, enhance, and interpret features from an image. Essential Earth Imaging for GIS provides a basic education in remote-sensing technology, promoting the effective use of sophisticated multispectral and 3D imagery. Readers are introduced to remote-sensing methods and types of imagery, as well as how to display and enhance multispectral images, process images in a GIS to improve quality, generate 3D data, and visually interpret images in a GIS to extract information from them. The book provides hands-on experience working with imagery in Esri’s ArcGIS for Desktop and ArcGIS Online. Exercises include assigning colours in multiband images and extracting information from multispectral images by digitalising features. Companion exercises and a free 180-day trial of ArcGIS are available by accessing the Esri Press Book Resources website.
