St. Petersburg, Russia

On top: the most Southern part of Ladoga Lake in
Northwestern European Russia (Karelia), the largest lake in Europe.
Located on the heavily glaciated Baltic Shield, the lake has low
and marshy shores in the South. It freezes every year for
two months in the North and four months in the South;
however, what one can see on the surface is not ice
but rather the wind effect as detected by SAR (the only frozen
areas along the shore are in dark tones).
To the right: because of the difficulties in navigation,
the lake's southern shore is paralleled by the Ladoga Canals,
160 km long, connecting the Svir and Neva rivers and
forming part of the Mariinsk System (see the Volga-Baltic
Waterway, a series of canals, locks and rivers) and the
Baltic-White Sea Canal. On the left shore: the outlet
of the Neva (see its course in the image), which empties
into the Gulf of Finland at St. Petersburg.
Along the right bank of the Neva, and at the right edge
of the image: rearing ponds used for fish farming.
At the left edge of the image: the city of St. Petersburg, located
in the Neva river delta on numerous islands, a fact that prompted
some observers to call it ''The City on 101 Islands''.
Below it: Pulkovo international airport.
City's centre: the river Neva and its primary delta arms
divide it into four distinct districts.
