HOW TO READ AND COORDINATE PIXEL VALUE

Diposting oleh Unknown


  • To find out the value of pixel image, right-click on the image window and select the Cell Values ​​Profile

  • Click on the image window, then the pixel value at that point will appear
  • The image has been geometrically corrected coordinate values​​. To display it, right-click on the image window and select Cell Coordinate.

  •    


  • Click on the image window, then the coordinates of the point will appear.



  • SAVING AND OPENING ALGORITHM

    Algorithm is the basic building within ER Mapper algorithm stores all the information necessary to display the data as an image. The information stored in an algorithm includes a data source, the colors used for display, data processing steps in detail. An algorithm is a revolutionary concept that separates the data from data processing. All data integration, data processing options other files contained in the algorithm. All this is created and edited by ER Mapper, ER Mapper which contain different types of data processing algorithms.

  • To keep the algorithm results, from the menu bar select File, then select Save As, type the name of the algorithm, algorithm or by clicking Save to save the algorithm directly or click the Save Algorithm As if to give a new name for an existing algorithm.
  • For example saved as rgb542.alg.
  • To open up the algorithm, from the menu bar select File, then select Open, select the name of the algorithm are shown.
  • In the image of the image will appear with the words    thereon. 542 rgb sentence indicates that the algorithm file being opened is rgb542.alg. while other signs have been described previously..

Activate ER Mapper Software Ver. 7.x

  • From the Windows XP or Windows 98/NT/2000 disable / close all other programs that are performing well and disable the screen saver program so as not to interrupt the work process to be performed.
  • From the Start menu select Programs and then select ER Mapper 7.x, then the image will appear as follows:

  • Select Run ER Mapper in Evaluation Mode when we do not have a Permanent License on the Software. Wizard will not appear when the permanent License Mapper ER has been held on a computer is concerned.

  • Or from a desktop computer can be searched shortcut icon as shown below, then click two times, so also will display a menu like the one above.

ERMAPPER application has 3 (three) windows / main window which is used to perform image processing in digital, that is the main window (Ermapper window), window image (image window) and window algorithm (algorithm window).

Window algorithm Er Mapper 7.0

Through the main window we can do and bring a variety of modules which are provided for image processing. All the image manipulation process, both formulas, filtering, preparation of composite and the other is displayed in the window algorithm. So we can say that this store window algorithm formulas that we do image processing. We can also do the editing of the image manipulation process through the window of this algorithm. The results of image manipulation will be displayed in the image window.
In the image window, there are several menus that can be run by right-clicking the mouse on the image window.

There are 5 groups of the menu that appears, namely:
Processing menu:
       Stop Processing (ESC), is used to interrupt the ongoing image.
       Image Refresh (F5), used to repeat the process of re-appearance of the image.
       Clip, a sharpening of the display image based on pixel values ​​that appear in the coverage area of ​​the image window. Sharpening is done by stretching the contrast based on the minimum and maximum pixel values ​​of coverage are shown.
Zoom menu:
       Previous Zoom, used to display images with the look as before.
       Zoom In, rear view
       Zoom Out, shrink the display
       Zoom to All Datasets, to zoom to the entire dataset area / surface are shown.
       Zoom to Current Dataset, zoom on area of ​​coverage of the dataset (layer / surface) were selected.
       Zoom to All Raster (Vector) Datasets, to zoom to the entire raster data (vector) are shown.
       Extent Zoom to Page, zoom into an area the size of paper used (depending on its setup page).
       Zoom to Page Content, zooming in on the contents of the map layout.
       Set GeoLink to None, remove GeoLink image window.
       Set GeoLink to Window (Screen / Overview Zoom / Overview Roam), set the image window to window geoling another image.
File menu:
Group menu contains standard menus are also available on the main window Ermapper.
Pointer menu:
These menus are used to change the mouse cursor functions:
       Hand, used for shifting the display image.
       Zoom, used to enlarge or shrink the image display by clicking the left mouse  drag down to raise or up to down.
       Zoom Box tool, used to zoom on a particular area in accordance with the desire to give depth to an area of ​​the box area in the area to be enlarged.
       Pointer
Ø  Information menu:
       Algorithm, is used to display the window algorithm.
       Cell Value Profile, to display the pixel value information window.
       Cell Coordinate, to display the information window coordinates.

Ermapper can display multiple image windows at once, but it only shows one window algorithm. The algorithms presented is an algorithm of the currently active window image or active the last time.

Surface    : can be said as a dataset, in which a single surface can consist of one or more                   layers. There are several types to choose from a surface, namely Pseudocolor, Red 

Green Blue or Hue Saturation Intensity. 

Layer : can only be on the surface, and can only display one channel only. 

Current surface / layer: a layer / surface is highlighted (highlight), the layer is currently active / 

selected for further processing if we do a copy, duplicate, move up / down or turn off / on. 

Invalid layer : the layer that does not correspond to the selected type of surface 

(pseudocolor, RGB or HSI). This layer will be displayed with a red cross and will not appear in the image window. 

Off layer : the layer is not active, so it does not appear in the image window.

ArcGIS 9.3.1 Tutorial for Beginners

Diposting oleh Unknown

Here is a tutorial ArcGIS 9.3.1 version made ​​by Br. Beni Raharjo. Concerned decided to share the tutorial before you have completed all due ArcGIS version 10 release, so no longer continue the project of making the spirit of the tutorial version 9.x These drafts are still vacant will be equipped with ArcGIS version 10 as well merevsi other drafts.


We think the tutorial is still very relevant to be shared because the release of ArcGIS version 10 does not necessarily make ArcGIS 9.x users directly migrated. Constraints such as license fees and technical constraints led to several years ahead, tutorial ArcGIS 9.x is still urgently needed.

Contents of this tutorial is as follows


  • Introduction to ArcGIS
  • The introduction of ArcMap
  • Creating a Map of Indonesia
  • Introduction to ArcCatalog
  • input Data
  • editing
  • Tables and Queries
  • data Display
  • Geoprocessing
