EVEN MORE USEFUL INFORMATION

The UNIX packages that we have reside on a SUN workstation called BRUNHES. To be able to run those packages we must run a X-TERM emulator that makes the PC mimic a terminal that runs UNIX packages.

The emulation package we have is called X-WIN32 (MicroX Inc).

The package is initiated the same way as any other WINNT package. This will bring up a standard clean window. CLICK on the X-Win32 icon in the top left-hand corner, select Sessions and then Brunhes.

This will bring us to the Login Window for the BRUNHES workstation.

ERMAPPER TUTORIAL

To start ERMAPPER, simply type ermapper at the prompt. We now have version 5.5 rather than 5.1 and thus some of the tutorial may not match exactly what is written in the 5.0 tutorial book.

PRINTING: We are now able to print to the 1600CM colour printer in ES1.

The output name is:

PostScript_Color/Postscript_Color_A4_geos420_1600cm.hc

(Note: that the output name PostScript_Color/Postscript_Color1600CM.hc will print to the printer when it is in my room)

First: Lets read and do the introductory exercises (17-26) in chapter 2 (User interface basics).

Pg 17: To move a window, use the middle mouse button (hold left and right buttons together) to hold and drag the window.

Pg 19: You must highlight (black background) a menu option before its sub-options are listed. Can use > and < arrows to go up and down the directory structure. Note: use Tutorials then Example_Landsat_TM or use Data_examples then Landsat_TM

Pg 21: Resize: move the window to the lower left corner of the screen. For our setup you need to move the mouse to the top right-hand corner of the window (hand should appear) and enlarge the window from there (left mouse button held down). To reduce a window, grab as above then initially increase the window size before reducing the size of the window to what you want.

Pg 24: Use Tutorials then Example_SPOT_Pan or use Data_examples then SPOT_Pan

Pg 26: To close/quit from a window, click the small blue icon on the top left-hand corner of a window, then select delete.

Chapter 3 (Creating an algorithm)

Pg 34: Note: lookup table found under the surface tab.

Pg 37: Lets print the resultant image. File then Print. Make sure the output printer is the one named above. Select the Fit page to output device box and then select print. Once the print is successful, close all the open print windows.

Pg 38: Instead of the "blank area", select PseudoLayer and type in NDVI and press enter.

Save the .alg file in your user?/dataset/ directory. Make sure your surname(s) appears in the title.

Chapter 4 (Working with data layers)

Pg 48: Tutorials then Example_Data_Mosaic

Pg 49: To turn a layer ON or OFF, right click the mouse and choose the appropriate option.

Pg 51: Tutorials then Example_Landsat_TM

Pg 53: Tutorials then Example_SPOT_XS

Pg 54: Note: you can drag a layer to a particular position without using the CTRL key. Use the scissors icon (cut) to delete the layers. Use the edit button to add new layers.

Chapter 5 (Viewing image data values)

Pg 60: Tutorials then Example_Landsat_TM

Pg 64: In 5.5 New Annotation is New Map Composition

Chapter 6 (Enhancing image contrast)

Pg 72: Save the algorithm and print the image after applying a lightening effect. Include in the name a reference to the page number and appropriate surnames.

Pg 74: Save the algorithm after the linear contrast stretch.

Pg 79: Save the algorithm after completing section 4.

Pg 83: To insert a second transform, you will find the appropriate option under the Edit button in the Transform window.

Pg 85: Shows the wrong icon for "Open an autoscale template algorithm". Note: Tutorials then Template_Common.
