introduction morphological segmentation of land surface is commonly used for land surface allocation in management and environmental sciences. the first step in assigning a piece of land to a specific application is to divide it into homogeneous morphological segments. traditional field-based geomorphological mapping can be time consuming, costly, and challenging when large areas, particularly ...

Parallel projections are often overlooked when designing a panorama, since most rendering packages use the central perspective projection as a default. The plan oblique projection, a particular parallel projection, has the interesting property of depicting the plan view of a terrain in correct shape. This paper presents the design and production of a panorama map using the plan oblique projecti...

This paper presents the critical spatial data constructs necessary for transportation applications that use and share data expressed in one to four dimensions. These spatial data constructs include spatial measurement and storage, spatial referencing and metadata, error propagation and transformation. The theoretical foundation and the characteristics for these constructs are provided along wit...

In the course of carrying out these activities, the environment is degraded and thereby damaging the ecosystem and the landscape, and offsetting the already fragile ecological balance [1]. Obviously, LUCC studies provide a great and significance information to strengthen the protection of land resources, determent unreasonable exploitati...

Migratory birds typically fly long distances in response to large-scale seasonal climate variation. However, most migratory species are partial migrants, and some only short distances, for example take advantage of suitable feeding conditions during the non-breeding season. In spite their distance, such migrations may also be fixed populations as a result evolutionarily adaptive responses local...

We have observed the interferometric suspension of a free-falling Bose-Einstein condensate periodically submitted to multiple-order diffraction by a vertical 1D standing wave. The various diffracted matter waves recombine coherently, resulting in high contrast interference in the number of atoms detected at constant height. For long suspension times, multiple-wave interference is revealed throu...

Kimberlites occur as dykes up to 3 m thick and isometric bodies in the southern explored part of a NE-SW trending Karoo graben across the Mozambique Belt in northern Mozambique. The kimberlites are reported along four NW-SE-trending zones, and one ENE-WSW-trending zone. The kimberlites are macrocrystic hypabyssal Group Ia kimberlites based on their mineralogy and whole rock geochemistry. The ki...
