常見問題Q&A

1.如何將等高線圖上的資料存入檔案中嗎?
--開啟SURFER -> 開啟 .GRD檔 ->  GRID -> GRID NODE EDITOR
--SAVE AS -> ASCII XYZ (.DAT)
2.SURFER 有Curve Fitting函數的功能嗎?
--沒有,TableCurve 3D具有此功能.
3.三維表面圖可與三維點圖合併在一起嗎?
--不可以,TableCurve 3D具有此功能.
4.可以將Surfer的輪廓線剖開,取出其Z值嗎?
--可以 Grid -> Slice  (.bln檔)
5.可以求取Surfer的體積嗎?
--可以 Grid -> Volumn.
6.可以將Surfer某部分不要畫出來嗎?
--可以 Grid -> Blank (.bln檔)
7.可以將數個Surfer圖重疊嗎?
--可以有兩種方法 Map -> Overlay Maps ; Stack Maps
Stack Maps 之功能為兩圖共用一軸
如將等高線圖與等高線圖完整重疊,共用水平軸與垂直軸
若需精密重疊,請選Stack Maps
Overlay Maps 之功能為將兩圖水平對齊,垂直則不對齊
如兩個三維表面圖 上下重疊,各圖仍享有獨立的軸(軟體上也無法共用同一軸)
建議您將Base顯示的選項去掉會更漂亮
任何圖形皆可做Overlay Maps

但Stack Maps則有限制
可以完整重疊的Stack Maps有
等高線圖+等高線圖
等高線圖+向量圖
向量圖+向量圖
等高線圖+三維表面圖Wireframe
等高線圖+3D Surface
Shaded Relief Map+3D Surface
等高線圖+Shaded Relief Map
等高線圖+Image Map
不可 Wireframe+Wireframe (建議用Overlay)

8.可以將Grid檔縮小嗎?
--可以 Grid -> Extract
9.可以直接用函數畫z=f(x,y)的曲面嗎?
--可以 Grid -> Function
10.可以畫向量圖? 如電磁場,熱流場,風向圖等.
--a.如果資料是X,Y,Z. 其中X,Y,是平面幾何座標,Z是物理量(如平板上的壓力)
----Gridding後 Map -> Vector Map -> New 1-Grid Vector 即可
----這是最基本的平面座標向量圖,直接以物理量Z值為向量圖依據.
--b.如果資料是X,Y,Z,Z1
----其中Z1是位於X,Y,Z上之物理量(如台灣各地的壓力).
----您必須做兩個Gridding後才能開始用New 1-Grid Vector
----X,Y,Z   幾何位置用(當底圖用,可以立體顯示)
----X,Y,Z1  物理量
--c.如果資料是X,Y,Z,X1,Y1
----其中X1,Y1是位於X,Y,Z上之x,y向量分量(如台灣各地的風速及風向).
----您必須做三個Gridding後才能開始用New 2-Grid Vector
----X,Y,Z   幾何位置用(當底圖用,可以立體顯示)
----X,Y,X1  x向量分量
----X,Y,Y1  y向量分量
--d.如果您的資料是X,Y,Z,Angle,Length
----其中Angle,Length是位於X,Y,Z上之向量角度及大小.做法同c.

風場向量圖
11.如何畫Surfer的Breaklines and Faults?
--可以 Grid -> Advanced options -> Breaklines and Faults (.bln檔要含Z值)
12.可以在Surfer上做程式嗎?
--可以,Surfer內建Surfer Script, 類似VB
13.可以在Excel上設計程式嗎?
--透過Excel的VBA,可以同時控制Surfer和Excel
14.Surfer的等高線動畫是如何做的?
--可運用動畫程式如Camtasia或Snagit搭配PowerPoint.
15.如果三維資料不等距,Surfer可以處理嗎?
--可以,Surfer專門處理此類問題
16.我有看到一張臺灣的圖,周邊有海洋的溫度等高線圖,溫度線不會穿過臺灣如何做?
--首先您先要有一張台灣的底圖(.gsb,dxf..),再用Blank(.bln)遮掉Taiwan底圖.
http://amrl.ev.ntu.edu.tw/daneel/archives/articles/images/trace_4.gif" _mce_href="trace_4.gif?>http:/amrl.ev.ntu.edu.tw/daneel/archives/articles/images/trace_4.gif" align=baseline border=0>
17.請問bln格式?
 length,flag
x1,y1
x2,y2
...
xn,yn
length,flag
x1,y1
x2,y2
...
xn,yn

17.如果我想要在等高線圖上放對應的高度文字該如何?
--用Classed Post Map
檔案格式如下
 x1,y1,label1
x2,y2,label2
...
xn,yn,label3
18.請問.GRD檔可以直接編輯?
若是Surfer預設的.GRD是可編輯的,GRID/GRID NODE EDITOR.
如果存成GS ASCII的.GRD可以用小作家編輯
檔案格式如下

DSAA
5 5
0 2
6 8
0 6
1 2 3 4 5
5 4 3 2 1
4 2 1 3 5
3 5 4 2 1
2 4 1 5 3

 

DSSA
Xn Yn
Xmin Xmax
Ymin Ymax
Zmin Zmax
Z11,Z12,Z13,Z14,Z15
....
Z51,Z52,Z53,Z54,Z55

 


19.請問Surfer可以做三角圖的等高線和影像圖嗎?
網路上有,我不會,作者Jeff告訴我如下
I used the ternary diagram feature in Grapher to plot the points shown on the figure.  I then created a file of thermal conductivity values based on the mineralogical composition and mapped
these points to an x-y grid which I contoured in Surfer.  As I recall, I also created a blanking file in surfer to match the shape of the ternary diagram.  I then pasted the Surfer contour plot into Grapher.
另外我們臺灣的核能所黃萬芬小姐有用Grapher寫出三角圖的等高線.

20.請問Surfer有提供曲線套配功能?
有,基本設定是Z=AX+BY+C的平面方程式
若您想其他請到GRID/Gridding Method/Polynomial Regression/Surface Definition
您甚至可以自訂高階的多項式函數
21.我想查任一X,Y的Z值,可以嗎?
可以直接在GRID/GRID NODE EDITOR即可.
或MAP/Digitize
22.我的Blank圖形要有被Blank的線,該如何做
您可以將Blank的.bln檔當Base Map,再予以Overlap Maps即可
23.Blank可以用幾次
不限次試,如此可以讓您做很複雜的Blank圖形
24.Surfer有網路版?
是的,Surfer也可以裝到網路上
25.Surfer有PDF檔
有,但必須由購買者申請,原廠才會給
26.曲面上可以疊上XY的圖?
可以Base Map + Overlay Maps 即可
Base Map必須由Grapher產生
27.曲面上可以加上一些空間上的點或線?
a.點芳面,可用Post map + Overlay Maps的技巧,但點會落在曲面上
b.很難,必須透過Base Map + Overlay Maps的技巧
c.用Voxler可以解決
28.等高線可以有Log軸?
沒有,但可以和Grapher一起使用就可以有
29.請問,用surfer畫等值圖時若有些數據沒有Z值,是否也能畫出圖形?還是要用外插等這類的估算出之後才能做圖?
若有些數據沒有Z值,則會忽略不計,與Z設為零是不同的.

30. 客戶應用範例:
將DTM(數位高程模型)資料透過該軟體轉換成grid檔案格式,然後產生等高線圖,所產生之等高線圖,設定好其等高線間隔、線寬、顏色等形式後,再匯出成為dxf或shp檔案,匯入AutoCAD Map或ArcMap等GIS軟體來套疊比對,另也該軟體內將航照影像套疊在等高線或3D面上。

31:我買了Surfer,請問為教學方便,有免費的試用版下載供學生做作業?   有

32: 如何預設資料表 x,y,x的位置?

於 Data 內 Assign XYZ Columns

33. 資料表如何排序?
DATA/SORT , 如 Sort First By A ,Ascending/Sort Next by B,descending,Sort Last by...
排序後可以看到最低和最高的數值


34. 資料欄如何計算?
DATA/Transform 如 C=A+B , 也同時可以設定第幾行First Row到第幾行Last Row , 並有多種函數Function可以使用

35. 資料如何排序?

在Worksheet/Data/Sort內 

36:請問一下關於網上有看到「全傑SURFER中文範例教學手冊」不知是否有可以索取嗎?
A:對不起 「全傑SURFER中文範例教學手冊」,是與作者合作,須付費給作者,所以我們是隨軟體販售.

37:請問SURFER能夠畫熱圖(Heat Maps)嗎?


A: SURFER v13可以畫熱圖!!
您可以參照網頁相關說明:
http://www.goldensoftware.com/newsletter/issue79-heat-maps-in-surfer

 

38. Norton 360 和 Norton Internet Security 會移除Surfer 執行檔
A number of users have also noticed that Norton 360 and Norton Internet Security removes the Surfer application executable after installation and
quarantines it. You can not run Surfer when the application EXE file is quarantined. If you are running Norton antivirus, you will need restore the
surfer.exe file from quarantine before you can run it.

 

Scripts for Surfer Version 10

 

In addition to the scripts below, there are over 45 additional sample scripts in the Surfer Samples folder, located in the installation directory. If you wish to download all of the Surfer 10 scripts at once, they are available in a zip file
