Table 1. Regions of Mars and related HRSC map products. (Map type designators following Greeley & Batson, 1990: OM = 
orthoimage mosaic; C = contour lines; N = nomenclature; T = topography, i.e. both contours and nomenclature; G = geology; K = 
color) 
The Martian surface is covered in 10,372 individual sheets in 
equal-area projections: Sinusoidal projection for latitudes 
between 85° north and south and Lambert Azimuthal Equal- 
Area projection around the poles. While all map sheets feature 
2° in latitude, the longitude extent increases from 2° in the 
equatorial zone towards 360° at the poles. Therefore, the 
mapped area is similar for all sheets (about 120x120 km 2 ). The 
series’ cartographic concept forms the basis for special target 
maps in different scales and also for thematic mapping (Albertz 
et al., 2004). 
The common Martian reference body for planimetry is a 
rotational ellipsoid with an equatorial axis of 3396.19 ±0.10 
km and a polar axis of 3376.20 ± 0.10 km. This parameter set is 
defined by the International Astronomical Union (IAU) as the 
Mars IAU 2000 ellipsoid (Seidelmann et al., 2002). According 
to IAU conventions two different types of ellipsoidal coordinate 
systems are in use. One consists of positive western longitudes 
in combination with planetographic latitudes (west/planeto- 
graphic), the other one of positive eastern longitudes and 
planetocentric latitudes (east/planetocentric). The latter is 
recommended by the Mars Geodesy/Cartography Working 
Group (MGCWG) to be employed in future map products 
(Duxbury et al., 2002). Therefore, the east/planetocentric 
system is defined also as the standard for Mars Express 
mapping (Albertz et al., 2005b). 
An Areoid (Martian Geoid) is the topographic reference surface 
for heights (Seidelmann et al., 2004). It has been derived from 
Mars Global Surveyor data and is defined as the equipotential 
surface (gravitational plus rotational) whose average value at 
the equator is equal to the mean radius of 3396.0 km (Smith et 
al., 2001). 
3. MAP PRODUCTS 
The first maps have been generated in summer 2004. Until the 
end 2007, a variety of topographic and also thematic maps of 
different Martian regions has been produced (Table 1, Figure 1). 
3.1 Topographic Standard Sheets 
In general, considering HRSC image widths (> 60 km), adjacent 
orbits have to be mosaicked to cover a sheet of the Topographic 
Image Map Mars 1:200,000 series. However, maps within the 
regular sheet lines have already been accomplished in summer 
2004 showing the Mangala Valles complex. Since then, several 
sheets of different regions of Mars have been produced (Albertz 
et al., 2005a, 2005b; Gehrke et al., 2006a; Gehrke et al., 2007a). 
Figure 2 shows two adjacent standard sheets in the north-polar 
region on either side of the 85° parallel, which is the transition 
of the two map projections. These topographic maps combine 
high-resolution HRSC orthoimages with contour lines from 
Mars Orbiter Laser Altimeter (MOLA). The sheets “M 200k 
84.00N/315.00E OMKT” (Sinusoidal projection) and “M 200k 
86.00N/326.00E OMKT” (Lambert Azimuthal projection) of 
the Topographic Image Map Mars 1:200,000 cover 2° by 18° 
and 2° by 24°, respectively. The depicted Chasma Boreale 
almost divides the ice cap and reveals (in Martian summer) 
layered structures of water ice and dust. Contour lines nicely fit 
with these layers and, moreover, give a good impression of the 
topography of the almost textureless ice cap (Gehrke et al., 
2007a). The standard map sheet of the north pole itself has also 
been produced.
