Forms of Bora BoraLandscape and landforms of France
France's land forms and countryside give an interesting and interesting view of the most beautiful countryside in France. Its aim is to give the readers an entertaining and instructive account of the places chosen within their geographic and gemological environment, to give an up-to-date view of the development of the French countryside and to give further information on the value of the culture of the places chosen wherever appropriate (prehistoric painting, legend of places, renowned vineyard, etc.).
Explanations of miracles of French Polynesia
France-Polynesia occupies the Pacific and comprises a large number of very different isles. Most of the islets here are low-lying and completely submerged by wave during the storm, but many are decorated with precipitous peaks that rise up to 2,241 metres high, surrounded by lush rainforest (Mount Orohena in Tahiti).
They are subdivided into several groups, each with its own scenic and culture but all are characterised by their distinct scenic beauties and wealth of culturality. High points of Franco Polynesia are: Various monuments of nature. Its varied nature reserves include a variety of unparalleled eco-systems - both above and below water levels, caverns, waterfalls and astonishing rock outcrops.
Archeological legacy. Each archipelago has astonishing archeological sites. Adminstrative divisions of Polynesia-English. Polynesia is an international region of France. There are 5 administration units: And even the fantasies seem dull when you compare them to the realities of the Marquesas Islands, especially the astonishing archeological sites.
The South Pacific specialist David Stanley knows the best way to go on holiday in Tahiti, from rummaging around the Papeete Mart to snorkelling off the Isle of Moorea. In this guidebook you will find great travel tips like The Best of France Polynesia and Underwater in the Tuamotu Islands.
Bora Bora Bora Bora Bora, Tahaa and Raiatea, France-Polynesia, Landsat and SIR-C pictures in comparison to SRTM Shaded Relief and colored height
The Bora Bora, Tahaa and Raiatea (from top to bottom) are Polish Isles about 220 kilometres westward and nordwest of Tahiti in the South Pacific. These representations compare three different "views from space" of these isles. A picture on the lefthand side of the Landsat 7 spacecraft shows the satellites as they might have been seen by an orbiter in 1999 (but somewhat more sharply and oppressed by a mist of atmosphere).
The centre shows an aerial photo of the third transmission of the Shuttle Imaging Radar (SIR-C) which flew in 1994. To the right is a graph showing the altitude information of the Shuttle Radar Topography Mission (SRTM) from the year 2000. In Landsat, you can see cloud formations that almost always lie above these isles, obstructing the area.
The SIR-C sees the wave and other wind impacts on the sea floor. Also it offers a bold (but distorted) look at the topographical pattern of the isles. The SIR-C' s cloud visibility is not restricted by cloud or shadow, thanks to the radar's cloud visibility and its own backlight.
The SRTM was developed to deliver new information that is lacking in Landsat and SIR-C overviews. SRTM has developed the world's first almost worldwide, highly granular altitude modell. SIR-C' topographical shadings in Landsat images and SIR-C' topographical radars give indications of the soil form but do not reflect the topographical high.
Therefore, they have not fully characterised the three-dimensional form of land forms. Earth's form and altitude of land forms affects almost every physical phenomenon and every form of man interaction that takes place on the Earth's surfaces, as well as vegetation development, hydrological supplies, transport and comunication. Therefore, the new information from SRTM is very useful for our comprehension and interaction with our world.
Landsat picture is an improved representation of visual colour (Landsat ribbons 1,2,3 in dark grey, dark grey, dark grey, red). As a result, the SIR-C picture shows the L-band radio readings (23.5 cm wave length, perpendicular transmission and reception) in white, C-band radio readings (5.8 cm wave length, perpendicular transmission and reception) in white and a discrepancy of the two (L minus C) in white.
The" sideways" radars were illuminated from the north-east as the Endeavour space shuttle was passing from the north-west to the south-east in a downward trajectory. The SRTM picture was created by combining two visualisation methods: colour coded topographical elevation plus topographical shadow. The colour code is directly related to the topographical altitude, with the lower altitudes of the trees becoming bright brown and light brown to very high.
The shade was deduced by calculating the topographical inclination in northeast-southwest orientation, so that the northeastern and southwestern sides appear light and the southwestern sides appear light, which generally coincides with the Landsat and SIR-C lighting orientations. The altitude information used in this picture was collected by the Shuttle Radar Topography Mission on board the Endeavour Space Shuttle, which was started on 11 February 2000.
The SRTM used the same type of radars as the Spaceborne Imaging radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR), which was flown twice with the Space Shuttle Endeavour in 1994. The SRTM was developed to gather 3D observations of the earth's surfaces. In order to gather the 3D information, the engineering team erected a 60-meter long tower, extra C-band and X-band aerials and enhanced positioning and navigational equipment.
