Iran: ESA - In questa immagine del satellite Envisat vediamo raffigurati parte dellIran (in alto) e della Penisola Arabica.

Il paesaggio iraniano presenta aspre catene montuose, un altopiano centrale, deserti, steppe e fasce costiere, a differenza della Penisola Arabica, dominata invece dal deserto.
Il punto dove i due territori sono più vicini è lo Stretto di Hormuz (al centro), il tratto di mare che mette in comunicazione il Golfo Persico (a sinistra) con il Golfo di Oman (a destra in alto) e il Mare Arabico (a destra più in basso).

In territorio iraniano sono visibili i crinali, gli altipiani e le depressioni della provincia di Hormozg?n e, parallela alla costa, lisola di Qeshm, la più grande dellIran. I piccoli vortici verde chiaro lungo le coste sono dovuti ai sedimenti trasportati nelle acque.

Nella penisola arabica invece limmagine inquadra Emirati Arabi Uniti (a sinistra), Oman (a destra) e Arabia Saudita (in basso a sinistra).

In Oman lunica zona montuosa si trova nella parte settentrionale della nazione, con numerosi picchi fra i 1500 e 2100 m. La maggioranza della popolazione risiede nella regione costiera di Batinah, la lingua di terra verde e arancio nellimmagine, affacciata sul golfo ai piedi delle montagne.

Le isole artificiali di Dubai davanti alla costa degli Emirati Arabi Uniti sono circondate da piccoli vortici di plancton e sedimenti. Il fondale relativamente poco profondo del Golfo Persico e lampia piattaforma continentale al largo delle coste di Dubai ne hanno reso possibile la realizzazione.

Limmagine è stata acquisita il 4 febbraio scorso ad una risoluzione di 300 m dallo strumento ottico MERIS a bordo del satellite Envisat.

LSNN is in continuous development and offers its own platform, to give space to authors, who fully exploit its potential. Your help is also needed now more than ever!

In a world, where disinformation is the main strategy, adopted to be able to act sometimes to the detriment of human rights by increasingly reducing freedom of expression , You can make a difference by helping us to keep disclosure alive. This project was born in June 1999 and has become a real mission, which we carry out with dedication and always independently "this is a fact: we have never made use of funds or contributions of any kind, we have always self-financed every single operation and dissemination project ". Give your hard-earned cash to sites or channels that change flags every time the wind blows , LSNN is proof that you don't change flags you were born for! We have seen the birth of realities that die after a few months at most after two years. Those who continue in the nurturing reality of which there is no history, in some way contribute in taking more and more freedom of expression from people who, like You , have decided and want to live in a more ethical world, in which existing is not a right to be conquered, L or it is because you already exist and were born with these rights! The ability to distinguish and decide intelligently is a fact, which allows us to continue . An important fact is the time that «LSNN takes» and it is remarkable! Countless hours in source research and control, development, security, public relations, is the foundation of our basic and day-to-day tasks. We do not schedule releases and publications, everything happens spontaneously and at all hours of the day or night, in the instant in which the single author or whoever writes or curates the contents makes them public. LSNN has made this popular project pure love, in the direction of the right of expression and always on the side of human rights. Thanks, contribute now click here this is the wallet to contribute
