In the introduction to world projection, we mentioned mocato projection, which isBy HollandCartographyG. Mercator was created in 1569. Currently, most popular map websites such as Google map and Baidu map all use this projection (Web mocato projection). Today we will briefly introduce this

1. Gauss-gram Gauss–krüger projectionGauss-gram Gauss–krüger projection This projection is by the German mathematician, physicist, astronomer Gauss in the 1820s, after the German geodesy home Crugge in 1912 to complement the projection formula, it is called Gauss-gram Gauss–krüger projection. Also known as transverse M

In fact, this article should be called (1). After all, this article mainly focuses on theoretical knowledge and the previous article focuses on implementation formulas. Map projection used by network maps such as Google Maps and Bing (it seems that Baidu map is also a mocato projection), which is often called Web Mercator, the main difference between it and conventional mocato

Projection and reflection any part of the backlight of an object will produce a projection. if it is on a brighter surface, it will also reflect the reflection of the object, such as the water surface, glass desktop, marble floor, etc. So how to implement the projection effect? The following small series will introduce you to pss' realistic

Iphone/Ipad wireless projection to PC, Iphone Ipad projection pc Original Blog, reprinted, please indicate the sourceBlog.csdn.net/hello_hwc Some projection technologies will inevitably be used for Demo presentation of applications. At this time, it seems a little bad to give a speech with a data line. At this time, wireless

Confused for some time, today began to tidy up their own, but also to organize new knowledge.CSS3:Start from scratch: Now the most used in the page is the picture/container projection, text projection;Next, we summarize a projection problem:Box-shadow: Shadow type X-axis displacement y-axis displacement shadow size shadow extended shadow colorGenerally this write

ellipsoid model (XI ' an 80) is most accurate in the Chinese region, its geometric center is certainly not the centroid of the Earth, but elsewhere. So this geometric center is called the Reference Center, referred to as the heart.On the earth a point latitude and longitude, is based on the reference ellipsoid to calculate, so, the same place, with Beijing 54, Xi ' an 80,wgs84 calculated longitude and latitude is three different values. Since GPS is WGS84, we see the latitude and longitude of t

ext.: http://www.cnblogs.com/graphics/archive/2012/07/25/2582119.html Overview The projection transformation is to show how to display the three-dimensional model to the two-dimensional viewport, which is a three-dimensional to two-dimensional process. You can consider a projection transformation as the focal length of the camera, which simulates the process of selecting a lens for a camera. A

Common JavaScript pop-up and back-projection advertisement implementation methods, javascript back-projection This article provides examples of common pop-up and back-cast advertisements in JavaScript. Share it with you for your reference. The specific analysis is as follows: Pop-up ads and background ads are mostly used on large websites and are also necessary code for webmasters. This code segment include

The previous modelview transformation is equivalent to placing the camera and adjusting the position and angle of the object to be photographed. The projection transformation corresponds to adjusting the camera lens distance to obtain the scene. BelowCodeSet the current matrix mode to projection matrix: Gl. glmatrixmode (gl_projection); Subsequent coordinate transformations are for the

§ 6 projection of vectors on the axis (projection) IAngle between two vectors of space: There are two vectors that are handed over to the point (if they are not intersecting, one of the vectors can be translated to make them cross), and one of the vectors is rotated inside the plane determined by the two vectors, so that the square direction of it overlaps with the square direction of another constant, so

Prerequisites: Paired with Hibernate environment. MyClass refers to an entity class that has been mapped wellThe following 3 functions are the methods I

Because GIS describes the spatial information on the Earth's surface, it must be embedded in a spatial reference system, which is a coordinate frame, which is based on parameters such as ellipsoidal bodies. The three main coordinate systems currently used in China are: Beijing 1954, Xi ' an 1980 and WGS84.With the coordinate system, the ellipsoid, the data layer has geographic coordinates, which are the locations of the spherical surface with latitude and longitude. In order to be able to conver

This article mainly describes how to use different languages to realize the normal calculation and Inverse Calculation of mocato, that is, the conversion of latitude and longitude and plane coordinates. Due to the rush of writing, there is something I don't understand in this article. I will add comments in turn in a few days.

The purpose of projection selection is to make the properties and features of the selected projection suitable for the purpose of the map, while considering that the map has a small deformation within the graphic range and the deformation distribution is even. GEO charts used in sea areas usually adopt angle-preserving projection, because they can maintain correc
