These are typically in the Digital Globe medium resolution dark brown images. It is a judgement call whether they are of more use than the general 15-meter TerraMetrics background images. We show a few examples in the attachment file.
This image contrasts the upper wintry area with the lower spring area.

____________________
You have to zoom in to see the speckles, typically to an altitude less than one kilometer.

Data Problems > Image Blemishes > Reflections
The Compendium Table of Contents contains a single network link which enables you to download the latest version of the entire Compendium in a single file of about 1.1 megabytes.
____________________________________________________________
There are several types of these image blemishes:
____________________________________________________________
Bright flashes: Examples in France, Germany, Japan, the UK, and the USA.
____________________________________________________________
Dutch diamonds: beautiful 10-pointed stars in Austria, Belgium, France, Germany, and the Netherlands
 
____________________________________________________________
Flares (only in DigitalGlobe high-resolution images)
- Unidirectional Flares - the most common
---- South-pointing flares: Large global collection in world cities. These are the most common, because most high-resolution images are north-south orientated. AZTraveller provides a very detailed explanation HERE
---- Non-south-pointing: Large global collection of such flares. They follow the direction of satellite travel. This effect was first noted by saukko HERE They almost all point in a variety of southerly directions. The only known exceptions were those in Formia, Italy, which have now been replaced by new imagery.
- Bidirectional Flares - rare
---- West and south bidirectional flares with examples in Canada Iceland, Iran, Japan, Morocco, and the USA. As with unidirectional flares, the usual satellite direction is south-pointing, so is the primary direction in bidirectional flares.
---- Other than west and south bidirectional flares: China and Gibralter - very rare.
---- Somewhat northerly-pointing bidirectional flare: Caracas, Venezuela is the only known instance
- Multidirectional flares
---- "Flare Island" The majority of the very numerous flares on Indonesia's Pulau Lagong (Lagong Island) are typical south-pointing. There is also a large number of bidirectional flares. However, a few unique groups of flares are west-pointing, and the eastern sides of those groups have been clipped in a vertical line.
____________________________________________________________
Oceanic low-resolution bright bars are apparent reflections in oceanic coastal areas in the TerraMetrics global background images. We show examples in Algeria, Canada, Libya, and Russia.

____________________
These are almost everywhere in the new high resolution imagery. We show a selection from France, Germany, the Netherlands, the UK, and the USA. "Hill" points out in THIS POSTING that these only appear in aerial photos, not satellite images. (The UK collection has been reduced since the September 2006 London updates and the March 2007 Manchester updates.)
- The largest and most complicated one is in the UK collection 21 May 2006
- The Moselle river has unusual black squiggles 11 October 2006

Data Problems > Image Blemishes > Swaths
The Compendium Table of Contents contains a single network link which enables you to download the latest version of the entire Compendium in a single file of about 1.1 megabytes.
____________________
Current count: 121 regular + 19 patterned = 140
Swaths are image blemishes, not data errors. Only new images can remove them.
- They are only on TerraMetrics 15-meter background images which are not known to be updated. They can be covered with higher resolution images.
- Straight lines pointing West by Northwest at angles of between 7° 50' and 9°
- Very straight edges, unlike aircraft contrails with irregular cloud edges
- Widths of about 1/2 kilometer. Lengths of 100+ kilometers.
- In bands of latitude at intervals of about 1° 30'
- There is no convincing explanation for these image faults.
- These appear identically in Microsoft's Windows Virtual Earth maps.
- Most are are bands of single colors
- 10% are in various complex patterns
Each is traced to permit detection of global patterns.

Misaligned Swaths
These differ from the above swaths because there are no unusual colorations or patterns. Rather, they are strips of shifted imagery about half a kilometer wide which stretch up to 170 kilometers. Their misalignments vary up to 200 meters. The discovery came about while studying Brazil's Rio Curuça river slippage (24 March 2006) for illustration.
The shifted swaths only occur in the TerraMetrics low-resolution background imagery. We have found 4 in Peru and 2 in Brazil, and the shifts are ALSO found in Microsoft's Virtual Earth AND in Yahoo Maps.
The effects are most visible where the swaths cross a river: Rio Curuça in Brazil, Rio Javan on the border, and Rio Amazonas in Peru We illustrate where some of the swaths cross the Amazon River in Peru.

____________________
- These are generally everywhere in the new high resolution images.
- They exhibit regular patterns of placement, though not on exact repeatable locations.
- Some have tiny (possibly intentional) variations.
- A possible explanation is "dirt in the lens." However, some have a complex cloud-like shape, or appear as very precise circular arcs.
- Some could be inserted purposely for copyright protection or image alignment.
