TUTORIAL SOFTWARE ER Mapper 7.x

Diposting oleh Unknown


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. 

Surface : can be said as a dataset, in which a single surface can consist of one or more layers.

GEOEYE?

GeoEye is the creation of the earth observation satellites are satellites that was launched on 6 September 2008 sponsored by Google and National Geospatial-Intelligence Agency (NGA) of California, the United States. Earth observation satellites is GeoEye commercial satellite imagery with the highest resolution images that exist in Earth orbit today.

GeoEye satellite has two satellites that GeoEye-1 and GeoEye-2. GeoEye-1 satellite launched by GeoEye Inc. who had also been issued IKONOS satellite which is sub-meter satellite a world first. GeoEye-1 is equipped with advanced technologies, used also by the artificial satellite company General Dynamics. GeoEye-1 satellite construction will cost $ 502 million a bear is Google and the NGA as its main sponsor. There is a Google logo is displayed on the side of the Delta II rocket is a rocket that launched GeoEye.

ITT Corporation is a maker of cameras on the satellite sensor is then in January 2007 sent to General Dynamics to be integrated into the GeoEye-1. Aerial photographs Kutztwon University Campus is the first image produced by the GeoEye-1 after the calibration process is complete.


Software Specification and GeoEye
GeoEye satellite capable of producing images with resolution up to 0.41 meters with a black-and-white sensor and 1.65 meter for a color sensor. Image resolution capability is owned by GeoEye is ideal for large scale mapping. GeoEye's orbit at an altitude of 681 km above the Earth and moving at 7.5 miles per hour.
GeoEye can map natural and man-made features to within 3 meters of the actual location on the earth because of GeoEye has a three-meter accuracy. In other commercial imaging system, this level of accuracy never achieved before, ever.
GeoEye has a very high accuracy and can collect a lot of images on a single pengorbitan. ITT was designing these satellites to be able to shoot multiple targets at all orbits. To get a thorough imaging, satellite was programmed in order to move forward, back, right and left of the target.

Frequency GeoEye Pengorbitan
GeoEye to orbit with a frequency of 15 times a day and takes 98 minutes to orbit. This satellite is also used to complement the IKONOS satellite system, but in the process of collecting GeoEye satellite images much faster which is 40% faster to collect black-and-white and 25% faster for color images. Both of these satellites in a single day can synthesize 1 million sq. km imaging results.
In black and white mode, GeoEye can perform imaging of an area of ​​700 000 km2 or area of ​​the city of Texas, while in color mode can GeoEye imagery covering 350 000 km2 - with the help of the camera optical telescopes, detectors, focal plane and the digital processor.


GeoEye Satellite function on Google
GeoEye satellite used in the web-based map service Google Earth and Google Maps. In addition to Google, GeoEye also provides data with high resolution imaging results for the interests of the United States through the NGA.
