Data Sets Sainte-Maxime & Hong Kong
Since its launch on 9th, January 2012, China’s first civilian high resolution stereo mapping satellite ZY-3 has provided a reliable stream of high resolution stereo image data. ZY-3 produces three line-array stereo panchromatic images (2.1-meter for nadir,3.5-meter for forward and backward) and 5.8-meter multispectral (red, blue, green, near infrared) imagery that can be combined in a variety of ways to accommodate a wide range of high-resolution imagery applications.

The experimental data is covering the Sainte-Maxime of France and Hong Kong of China, respectively. Every region contains four folders, which means four camera of ZY-3 (Nadir, Forward, Backward and Multispectral imagery). Every folder contains the SC imagery (sensor corrected imagery) and standard RPC file, and the shape file is put in the sub-folder named as ”GeoRange”.
The four corners of the imagery covering the Sainte-Maxime are Left-Upper: 6.349°E and 43.628°N, Right-Upper: 6.968°E and 43.523°N, Left-Bottom: 6.196°E and 43.132°N, Right-Bottom: 6.811°and 43.031°N for, which is illustrated on Figure. 1. And the preview of ZY-3 multispectral imagery is showed on Figure.2.
The four corners of the imagery covering the Hong Kong are Left-Upper: 113.935°and 22.625°N , Right-Upper: 114.419°E and 22.531°, Left-Bottom: 113.828°E and 22.129°, Right-Bottom: 114.309°E and 22.037°N, which is illustrated on Figure.3. And the preview of ZY-3 multispectral imagery is showed on Figure.4.
