This is why people pay attention to the important reason for home feng shui.Most of the houses in rural areas are self-built. The front door is very fastidious, generally with faces south as the best. Because the orientation of the direction is

, and the average radius is 6371.004 km. If we assume that the Earth is a perfect sphere, its radius is the mean radius of the Earth, which is recorded as R. If the zero-degree longitude line is used as the basis, the distance between the two points can be calculated based on the latitude and longitude of any two points on the Earth's surface. (here, the error caused by the calculation of the earth's surface topography is ignored, only theoretical est

of these squares. When we want to describe the narrative path, the data of the parent square is very important. The specific purpose of this will be explained later.3. Remove point A from the open list. Add it to a "close list" and keep a list of all squares that do not need to be checked again.4. Remove the node with the lowest F-value from the open list, and then add it to the close list.5. Check all adjacent squares. Skip those that are already in the closed list or not (there are walls.

man-made river that runs through the Great West Gate to the library artificial lake, where it is used to cut down the topography and dig out the river and also dig out the artificial lake. Now the general terrain has been created, and then began some landscape carving, the first import of water resources, so that its area is large enough, and then move upward along the Y axis, is the horizontal plane is just below the ground level. Then, using a brus

The application of DEM occupies a very important position in the three-dimensional performance of WW, which is as important as image data. Fortunately, the image and DEM loading and processing principles are almost consistent, for the WW GIS three-dimensional development is a good thing to understand any one, another kind of analogy! The previous article, mainly from the function of a simple introduction, this article will be from the code level analysis of WW built in the Srtm DEM data loading

time spent on the search for an Air France airliner was planned, and the Air France investigation group spent 10 weeks searching for it, 8 weeks in a preview of a possible fall zone. 　　Therefore, determining the search scope is the most important thing, but from the MH370 case, it is very difficult, because there is no clue now. 　　Compare search and Rescue difficulty Malaysia's larger search-and-rescue area the world's worst Air France AF447 landed at the top of an underwater mountain range, an

the earth is about 40008km.

If we assume that the earth is a perfect sphere, then its radius is the average radius of the Earth,

To give you painter software users to detailed analysis of the process of drawing siege to share the tutorial. Analytical sharing: 01. At first I didn't know I was going to do a thing, so I used a big brush to find the feeling 02. Initially feel that you can also find a further look at what kind of space you want 03. At this point I probably know what to do with something, but I'm not sure, so it's still a tentative act on the building, and a l

from the perspective of architecture, and the object-oriented thinking runs through all the Times. So at the beginning of the new year, the blank-level scene editor was born, what could it do? You may wish to look at the following picture: The picture contains 4 screenshots of different games, from the ground topography analysis of its practices are traditional "tile". Friends who have done similar development know that, in a sense, this kind of w

Industry needs the wireless network area mainly divides into the office teaching area, the experimental building area, the dormitory area, the football field and the stadium hall, the outdoor leisure square, the library, the International Exchange Center and so on several parts. In the above area, Rui Jie according to the region's topography, building distribution and the estimated number of users, the density of appropriate, without leaving a corner

coverage of PS384 service can reach about 1.2km, that is, the coverage of low transmission rate service is slightly larger than that of high transmission rate business. For network coverage, be aware of such two points. The factors that usually affect coverage include the following factors, which should be considered in the design of the network: • Antenna height, antenna azimuth/dip angle, base station transmitting power, different landform topography
