SurView TutorialMiscellaneous features |
|
|
In SurView, the right mouse button is used for Picking features. The left mouse button is used to measure distances. Click the left mouse button, hold it down and drag the mouse and the distance (m) will be displayed in SurView's caption area.
The line measuring the distance between the two yellow features in this image has been enhanced for clarity.
This method of measuring distance can also be used in the stacked
profile window, except that movement of the cursor is restricted to
the horizontal direction, parallel to the flight line.
|
SurView's 'smart cursor' can display the location of the cursor on
the map in a variety of modes. Activate the smart cursor with the
View | Smart (E,N) cursor menu item. You can move the small
window around and place it anywhere convenient on the screen.
The default display is (easting, northing) metres. Click
the cursor window's system menu on the left to bring up a menu
of display options:
Display mode | Example |
---|---|
(easting, northing) metres | ![]() |
(longitude, latitude) signed degrees | ![]() |
(longitude, latitude) NEWS degrees | ![]() |
(longitude, latitude) NEWS (d,m,s) | ![]() |
NTS sheet number | ![]() |
UTM zone | ![]() |
Grid (col,row) & grid value | ![]() |
(E,N) metres & grid value | ![]() |
|
A variety of special keys can be pressed to activate several different features.
Menu accelerator keys
Arrow keys, numeric keypad 1-9 & Insert/Delete keys
Esc key
Tab key
The popup menu identifies the copies of SurView as follows:
Flag | Interpretation |
---|---|
the current copy of SurView is disabled | |
[-] | denotes a minimized copy of SurView |
[+] | denotes a maximized copy of SurView |
This feature was designed to be similar to the Windows ALT-TAB feature used to cycle between windows/applications, and concerns itself solely with other copies of SurView (not other applications).
Other keys: 0-9, A-Z, F1-F12
Id | To activate... |
---|---|
-id=3 | press '3' |
-id=X | press 'X' (case is ignored) |
-id=F6 | press function key F6 |
For example, you might have several copies of SurView running, one of which is displaying an index map. If that copy has been identified with "id=X", then it can be brought forward with a single "X" keystroke, entered into any other copy of SurView.

Any window can be resized manually by dragging the corners or sides. The View | Resize window(s)... menu item also provides a way to size the current SurView window and the windows of other copies of SurView.
Each of the dimensions (width & height) of the current window can be adjusted independently to the smallest or largest SurView window of all of the running copies. Either dimension can be set to an explicit size (pixels).
Finally, the new window size can be broadcast to all other running
copies of SurView to adjust their windows to the same size. Coupled with
the ability to Zoom/Pan
all of these copies of SurView together, this provides a very powerful
feature to synchronize several windows viewing different sets of data
for the same area.

Windows provides the PrintScreen key to copy the current screen (all windows) to the clipboard. Alt-PrintScreen is used to copy the current window to the clipboard, including the frame, caption and menus.

Note that SurView only copies an image to the clipboard (as of version 1.73). A future version will allow the picture to be copied to the clipboard as a Windows metafile.
|
You can use the File | (DOS) Prompt to launch a console window for quick access to the shell (usually command.com or cmd.exe). The working directory of the shell matches that of SurView. This is identical to the often-used but incorrect and dopey phrase "Exit to DOS".
|
You can launch a new copy of SurView at any time by using the File | Launch a new copy of SurView menu item. SurView uses very little memory and it's not unreasonable to have 10 copies of it running at any given time on a normal system.
|
ASX files can be configured with two sets of file titles, window captions & legend descriptions/titles. Options | Use alternate language where available can be used to switch between these two sets (usually english and français). You may find this option already active after loading an FDL or ASX file, since the initial setting can be specified by the developer who prepared the files. If Use alternate language... is enabled, and the files do not have titles or data in 'another language', the primary language will be used instead.
