Internet PIKES Demo - demo
The lines beginning with a ">" can be followed to perform a
simple demonstration of the capabilities of this demo version
of the PIKES Interpreter's Assistant.
Note that step (1) must be performed in order to perform any
of the other steps, though they may be performed in any desired
order after (1) is completed. Essentially, a View must be open
before anything can happen.
(1) Open a View
> View | Open | [enter] to select 'Sprisa'
The Interpreter's Assistant function is centered on the View window.
A View window is:
o a standard Windows window,
o an image,
o a number of vector data layers, and
o a transformation between the image and the vector data layers.
In this version of the Interpreter's Assistant, the vector data
layers are linked to the image through the single transformation;
that is, they are all defined in the same coordinate space.
In order to use any of the Interpreter's Assistant function, we
therefore need to open a View.
(2) Show the View Control Tools
(2.1) The Status Bar
> Tools | Show Status Bar
The Status Bar displays the name of the current View, the cursor
location, and other miscellaneous information. The cursor location
is given in vector data coordinates.
> Select the open View window (click on the title bar to activate it).
> Move the cursor around within the View window and notice that the
UTM location of the cursor and the elevation in meters, are displayed
in the Status Bar.
(2.2) The Navigation Quadrant
> Tools | Show Quadrant
Each View window has standard Windows scroll bars, but the
Navigation Quadrant may be used to pan the View vertically and
horizontally, as well as in diagonal directions. The Navigation
Quadrant is also used to scale the View. By using the Zoom In
and Zoom Out controls, the View can be scaled by 4, 2, 1, 1/2,
and 1/4 of actual size. A scale of 1 means that one source image
pixel occupies one screen pixel; the transformed vector data
layers are transformed after the scaling.
> Resize the open View window so that only a small portion of the
View is visible.
> Using the Quadrant, pan the View South-East, North, and West to
return to the original pan location.
> Zoom in and Zoom out.
(2.3) The Layer Selector
> Tools | Show Layer Selector
The individual parts of a View can be turned off and on. The
Layer Selector toggles the display state of the image and the
vector data layers. The Interpretation layer is a special
vector layer interactively created by the user. Its use will
be explained later.
> Toggle the View image.
> Toggle all the Map layers.
> Toggle individual Map layers.
> Until an Interpretation map has been created, the Interp
toggle will appear to be ineffectual.
(3) Show the Toolbox
> Tools | Show Toolbox
The Toolbox provides the user with a number of drawing tools and
operations for creating an Interpretation map - one of the vector
data layers of the View window. Additionally, it allows the user
to toggle the display of the other Tools.
Toolbox drawing tools/operations:
Select Edit-Text Text-Auto Text-Prompt
Draw-Continuous Draw-Segmented - -
[ For left-handed mouse users, reverse left with right, in the
following descriptions. ]
(3.1) Segmented line drawing
> Resize the View window to make enough room to draw in.
> Choose the Draw-Segmented Tool. Position the cursor within the
View window. The cursor will be a pen shape.
> Click the left button to drop the first point.
> Move the cursor.
> Click the left button for as many additional segments as desired.
> Click the right button to stop drawing segmented lines.
or
> Press the SpaceBar to 'close' the polygon.
(3.2) Continuous line drawing
> Resize the View window to make enough room to draw in.
> Choose the Draw-Continuous Tool. Position the cursor within the
View window. The cursor will be a pen shape with a '~'.
> Click and hold the left button to start drawing.
> Move the cursor while holding the button to continue drawing.
> Release the left button to stop drawing continuous lines.
(3.3) Automatically Numbered Text
> Resize the View window to make enough room to place a number in.
> Choose the Text-Auto Tool. Position the cursor within the
View window. The cursor will be a cross and '#' sign.
> Click the left button to place a number.
> Repeat as desired.
(3.4) Prompted Text
> Resize the View window to make enough room to place text in.
> Choose the Text-Auto Tool. Position the cursor within the
View window. The cursor will be a cross and 'I-bar' cursor.
> Click the left button to place the text.
> A prompt window will appear: enter some text and key Enter.
> Repeat as desired.
(3.5) Edit Text
> Choose the Edit-Text Tool. Position the cursor within the
View window. The cursor will be a cross and hollow arrow cursor.
> Click the left button on some previously placed text or number.
> A prompt window will appear: edit the text and key Enter.
> Repeat as desired.
(3.6) Select Line or Text
> Choose the Select Tool. Position the cursor within the
View window. The cursor will be a hollow arrow cursor.
> Click the left button on some previously placed text or number,
or drawn line.
> The selected object will be coloured in Magenta.
> The object can be moved with the 4 arrow keys, or deleted
with the Delete key. (It may be un-deleted immediately with
the BackSpace key.)
(4) Use the Record Editor
> Tools | Record Editor
The Record Editor acts as a 'spreadsheet' for data associated with
Views, as well as a browser for previously interpreted cases.
(4.1) Case Record Browser
> Select the "Browse" button. A list of records will appear in the
spreadsheet.
> Choose any record, and select the "Show Key" check box for that
record. A new window will appear.
> The record data in the Record Editor is associated or describes
the new case or 'Key' window which just appeared.
(4.2) Digitization Editor
> Perform step (3) as described above.
> Select the "View" button in the Record Editor. The number "1"
will appear next to the button, and a list of items will appear
representing each of the objects created in (3) above.
(5) Show the Image Enhancement dialog
> Enhancements | Enhance
This dialog shows some of the types of image enhancements possible
within PIKES. No actual enhancement can be performed with this
demonstration version, but this dialog indicates the kind of
control the interpreter is afforded in the complete system.
(6) Show the Perspective Image View dialog
> Enhancements | Perspective View
This dialog collects parameters for the creation of a perspective
view of the current View window image draped over its DEM. There
is no supplied function in the demonstration system, but a sample
of its use can be displayed.
> Select the "Open" button in the Perspective View dialog, and
key Enter to select the only available Perspective view image.
