PASCO Satellite Ortho (PSO) is the rectified image of the pre-processed data, through orthorectification processing for the entire area. As it also comes with spatial coordinates, overlapping with data that customers already have in their Geographic Information System (GIS) is easy, and customers can make use of this product quickly.
Characteristics of PASCO Satellite Ortho (PSO)
PSO is produced by creating pan-sharpened (*2) orthorectified images from ALOS (*1) satellite photographic images (PRISM and AVNIR-2).
PSO maintains a high level of product quality with a maximum spatial resolution of 2.5 m. As such, it can be used for the creation of background images, large-format output maps and panels, as well as pamphlets and booklets, on GIS.
*1 ALOS: The Japan Aerospace Exploration Agency's (JAXA) Advanced Land Observing Satellite "Daichi" launched in January 2006
*2 Pansharpening: Creating a composite image from medium resolution panchromatic 2.5 m and low resolution color 10 m images.
- As it comes with coordinates using the control points and verification points for the numerical map 2500, it has a high degree of positional accuracy.
- As these orthorectified images comprise seamlessly mosaicked satellite images acquired under cloud cover of less than 10%, it is possible to get a good grasp of conditions over a wide area of ground surfaces.
- The area provided is a minimum of 20 km x 20 km.

An Example of an Interpretation through False Color (*3)
|[Interpretation of logging period]||[Interpretation of vegetation]|
|A: Time has passed since logging was carried out, and vegetation overgrowth can be observed.||C: Cedar|
|B: This is immediately after logging, and the ground surfaces are exposed.||D: Broad-leaved trees|
*3 False color: A method that emphasizes the display of red colors for near-infrared wavelength ranges, in order to show the degree of activity of vegetation in the areas of forestry and agriculture.
