Surfer插值方法介绍
1、距离倒数乘方法
距离倒数乘方格网化方法是一个加权平均插值法,可以进行确切的或者圆滑的方式插值。方次参数控制着权系数如何随着离开一个格网结点距离的增加而下降。对于一个较大的方次,较近的数据点被给定一个较高的权重份额,对于一个较小的方次,权重比较均匀地分配给各数据点。
计算一个格网结点时给予一个特定数据点的权值与指定方次的从结点到观测点的该结点被赋予距离倒数成比例。当计算一个格网结点时,配给的权重是一个分数,所有权重的总和等于1.0。当一个观测点与一个格网结点重合时,该观测点被给予一个实际为 1.0 的权重,所有其它观测点被给予一个几乎为 0.0 的权重。换言之,该结点被赋给与观测点一致的值。这就是一个准确插值。
距离倒数法的特征之一是要在格网区域内产生围绕观测点位置的\"牛眼\"。用距离倒数格网化时可以指定一个圆滑参数。大于零的圆滑参数保证,对于一个特定的结点,没有哪个观测点被赋予全部的权值,即使观测点与该结点重合也是如此。圆滑参数通过修匀已被插值的格网来降低\"牛眼\"影响。
2、克里金法
克里金法是一种在许多领域都很有用的地质统计格网化方法。克里金法试图那样表示隐含在你的数据中的趋势,例如,高点会是沿一个脊连接,而不是被牛眼形等值线所孤立。
克里金法中包含了几个因子:变化图模型,漂移类型 和矿块效应。
3、最小曲率法
最小曲率法广泛用于地球科学。用最小曲率法生成的插值面类似于一个通过各个数据值的,具有最小弯曲量的长条形薄弹性片。最小曲率法,试图在尽可能严格地尊重数据的同时,生成尽可能圆滑的曲面。
使用最小曲率法时要涉及到两个参数:最大残差参数和最大循环次数参数来控制最小曲率的收敛标准。
4、多元回归法
多元回归被用来确定你的数据的大规模的趋势和图案。你可以用几个选项来确定你需要的趋势面类型。多元回归实际上不是插值器,因为它并不试图预测未知的 Z 值。它实际上是一个趋势面分析作图程序。
使用多元回归法时要涉及到曲面定义和指定XY的最高方次设置,曲面定义是选择采用的数据的多项式类型,这些类型分别是简单平面、双线性鞍、二次曲面、三次曲面和用户定义的多项式。参数设置是指定多项式方程中 X 和 Y组元的最高方次 。
Surfer is a contouring and 3D surface mapping
program that runs under Microsoft Windows. It
quickly and easily converts your data into
outstanding contour, 3D surface, 3D wireframe,
vector, image, shaded relief, and post maps.
Virtually all aspects of your maps can be customized
to produce exactly the presentation you want.
Producing publication quality maps has never been
quicker or easier.
Surfer is the most powerful, flexible, and
easy-to-use contouring and 3D surface mapping
package available. Surfer easily and accurately
transforms your data into spectacularly colorful
contour, surface, wireframe, shaded relief, image,
post, and vector maps in minutes! And best of all,
Surfer is affordable!
Surfer provides more gridding methods and more
control over gridding parameters than any other
software package on the market. Surfer will quickly
interpolate irregularly or regularly spaced data
into a useful, functional map. Use Surfer's default
settings or choose from twelve different gridding
methods. Each gridding method provides complete
control over an abundant number of gridding
parameters to generate the most accurate map
possible to best represent your data. Creating
high-precision maps has never been so easy!
In addition to creating surfaces, grid files allow
you to perform a variety of functions. Just a few of
the possibilities are calculating volume and area,
subtracting or adding grid files, or converting
outliers to a minimum or maximum value. Grid files
also enable you to apply filters to emphasize
details or remove background variation, blank a grid
file to prevent contours from being drawn through
specific areas (buildings, roads, or outside of
field areas), or create cross sections.
Customize your maps so they look their best! Each of
Surfer's ten map types has a multitude of editing
options to enhance its appearance. Change line
colors and thicknesses, edit point shapes, sizes,
and colors, or add gradient color fills and color
scale bars. Contour maps allow you to manipulate
contour line intervals, thickness, color, and
labeling. For shaded relief maps and 3D surface
maps, quickly change the lighting angle for a
realistic appearance. Create maps with multitudes of
information by including scale bars, legends, and
labels. These are just some of the endless options
Surfer offers to easily create the most colorful,
descriptive, and understandable maps - ready for
publication!
Options for creating informative maps are endless!
The smallest details are easy to apply and modify
with Surfer's extensive customization abilities!
Surfer lets you massage your data in many ways to
achieve the exact output you want. Surfer includes a
full-featured worksheet for creating, opening,
editing, and saving data files. Data files can be up
to one billion rows and columns! You can cut, copy,
and paste data within the Surfer worksheet or
between applications, and you can use Surfer's find
or find/replace commands to search for and replace
data. Sort your data on a specified column,
transform data with equations, filter data with
specified rules, and calculate statistics on your
data! You can also assign a projection to your data
and reproject the coordinates to a new projection or
coordinate system! Surfer lets you get the right
answers to your questions, simple and fast!
Surfer includes extensive customization options to
allow complete control over all map types. Overlay
or stack any number of maps and display an unlimited
number of maps per page. Scale, tilt, and rotate
your maps for the best data presentation possible.
Customize maps by adding text, symbols, polylines,
and polygons. With Surfer's Object Manager, all of
the objects on the page are logically organized and
are readily accessible for editing. No other mapping
software makes maps as easy to create and edit and
as customizable as Surfer!
Create your own scripts to automate repetitive
tasks! Don't spend time doing the same process over
and over again - write a simple script to simplify
your life! Operations performed interactively can be
controlled using an automation-compatible
programming language such as Visual Basic, C++, or
Perl. Surfer includes Scripter, a built-in Visual
Basic compatible programming environment that lets
you write, edit, debug, and run scripts. Why do more
work than you need when you have Surfer working for
you!
