  • When seen from space, “Planet Earth” is a mix of clouds, with the majority (two thirds) of the total surface under ocean water with the remaining third of land forming what we call continents, with various degrees of increasing albedo from open water bodies, vegetation, bare soil, rocks, deserts, and snow/ice packs. In a very short time (relative to Earth's age), the modern human civilization has conquered its neighboring space with probes, satellites, and vehicles carrying humans for exploration.

  • Up to present, in Vietnam, the traditional methods used to map marine bathymetry are still very popular. These techniques have advantages of giving a high accuracy but still show big disadvantages of taking too much time for the data acquisition and processing and of being very expensive for the field works. Compensated to these cons the remote sensing technique seems to be an ideal solution since the images covers almost places on the earth with very high frequency (hours) of acquisition and served with a reasonable price even some of them can be downloaded from the internet for...

  • Nowadays it is hard to find areas of human activity and development that have not profited from or contributed to remote sensing. Natural, physical and social activities find in remote sensing a common ground for interaction and development. From the end-user point of view, Earth science, geography, planning, resource management, public policy design, environmental studies, and health, are some of the areas whose recent development has been triggered and motivated by remote sensing.

  • The Art of Public Speaking or less consciously invented the unreal on the basis of the real. And just here the fictionist, the poet, and the public speaker will see the value of productive imagery. True, the feet of the idol you build are on the ground, but its head pierces the clouds, it is a son of both earth and heaven. One fact it is important to note here: Imagery is a valuable mental asset in proportion as it is controlled by the higher intellectual power of pure reason. The untutored child of nature thinks largely in images and...

  • Plants are a distinct kingdom of organisms that possess unique properties of reproduction, development, physiology, and adaptation. Plant diversity refers to the variety of plants that exist on the Earth. Plants, in order to survive, have to compete with other plants and organisms in an ecosystem. Over time, they have developed various characteristics to help them survive, which leads to plant diversity.

  • In the middle of the 20th century, we saw our planet from space for the first time. Historians may eventually find that this vision had a greater impact on thought than did the Copernican revolution of the 16th century, which upset the human self-image by revealing that the Earth is not the centre of the universe. From space, we see a small and fragile ball dominated not by human activity and edifice but by a pattern of clouds, oceans, greenery, and soils. Humanity's inability to fit its activities into that pattern is changing planetary systems, fundamentally.

  • Cross drawings are as old as time. They have been around even before Christ and Christianity. The cross symbolizes life, immortality,union of the heavens and earth and the sun and stars. It's no wonder so many people select this image as a tattoo. It is arguably the most widely used image in both ancient and modern tattoos. Throughout history each culture has reinvented and redesigned this sacred image leaving us with many different versions. There are many variations of cross drawings which I will display below. Again as with tattoos and other drawings, personal taste and style rules all....

  • In the method of creating digital terrain model (DTM) by using digital photogrammetry, the picket sampling interval (PSI) plays an important role since it strongly influences on the production effectiveness and on the accuracy of created DTMs. The optimal value of PSI must be balanced between requirements of effectiveness and of accuracy. This research is focused on the influence of PSI on root mean square error (RMSE) of created DTM and on the number of error pickets (caused by limitation of image matching technique) that must be checked and corrected manually.

  • Fear has dominated much of the experience of the human race from earliest times. Fear of death, fear of natural disaster, fear of human enemies and fear of deities: these were fused together beneath a dense shroud of the unseen and the unknown. The major impact of physics on civilisation has been to roll back this shroud. Physics explains. It enables us to see inside the Earth and inside our own bodies. It gives us ways to probe and to cure.
