Satellite Imagery

Acquiring updated satellite imagery is often the first step in a project. It provides a synoptic overview of the study area, and is useful for first-order reconnaissance and photointerpretation. This is especially true in remote areas where coverage of freely-available data may be limited to 15m Landsat ETM+ imagery and SRTM-3 DEMs. Depending on the resolution, satellite imagery can be orthorectified with a lidar DEM and used for supplemental image overlays. In other cases they can provide historical imagery for time-change studies or other temporal analysis that requires retroactive data.

Point3Data can provide high-resolution (sub-meter) remote sensing imagery from a number of Earth Observation constellations, including:

WorldView-2 (DigitalGlobe)

NIR2 (950 nm), NIR1 (835 nm), Red Edge (725 nm), Red (660 nm), Yellow (605 nm), Green (545 nm), Blue (480 nm), Coastal (425 nm)

Pléiades 1 (Astrium)
Resolution: 50 cm (2 m MS)
Bands: Panchromatic (480-830 nm) + 4-band multispectral:
NIR (800 nm), Red (660 nm), Green (550 nm), Blue (490 nm)

GeoEye-1 (GeoEye)
Resolution: 50 cm (1.65 m MS)
Bands: Panchromatic + 4-band multispectral:
NIR (1012 nm), Red (660 nm), Green (560 nm), Blue (485 nm)

QuickBird (DigitalGlobe)
Resolution: 65 cm (2.42 m MS)

NIR (800 nm), Red (672 nm), Green (545 nm), Blue (480 nm)

A variety of image products are available, including natural color and color infrared with or without pan-sharpening. Other imagery with varying resolutions, spectral bundles, acquisition modes, re-visit times, collection schedules and levels of processing can be provided to suit specific requirements.
