has a single dataset, but supports multiple bands. 1 The size of the image is given in
columns (7,801) and rows (7,571).

Coordinate System is:
PROJCS["WGS 84 / UTM zone 29N",
GEOGCS["WGS 84",
DATUM["WGS_1984",

The next block of information is related to the coordinate system and is listed in
the well-known text (WKT) format. This is a nested structure with at the top level
the names of the geographic coordinate system (WGS84) and projection (UTM zone
29N). This combination can be referred to as a single EPSG code (32629), listed in
the last line of the block. The next levels further specify the projected coordinate
system and the underlying geographic coordinate system (GEOGCS). If available,
the corresponding EPSG codes for each of the nested items are also listed (check
for the AUTHORITY keyword). The GEOGCS consists of the spheroid (WGS 84,
EPSG:7030), the datum (WGS 84, EPSG:6326), the primemeridian (Greenwich) and
angular units (degree). There is a single EPSG code that covers the entire GEOGCS:
EPSG:4326. The projection system (TransverseMercator) with its related parameters
(latitude of origin, central meridian, ...) are listed next. More information on spatial
reference systems is explained in Sect. 8.7 .
