EARTH OBSERVATION DATA SOURCES
|
Planetary Visions can obtain and process data from a variety of Earth Observation sensor systems to support our computer graphics and digital cartography projects. The examples below show the level of detail available from satellite systems and air photos. Global coverage is available in-house from our Satellite Imagemap product, based on NOAA AVHRR weather satellite imagery, down to a pixel size of 1 kilometre. The other datasets need to be acquired for specific locations,
and are subject to archive availability. The image samples below are full-resolution extracts from cloud-free or nearly cloud-free images. Full images are typically several thousand pixels across. Generally speaking, a sensor showing more detail (with a smaller pixel size) will cover a smaller area of ground in each image. Images are provided for evaluation only and may not be otherwise used without permission. |
