This is used to quit a window or the program.

Restore Size

Will restore a view to original target area (full zoom out)

Zoom out

reverts back one zoom level

Zoom in

zooms in one level

Screen Bound

this button will snap a figure back to fit the screen if it has popped out, or patially out, of view.

Aspect 1-1

changes window size so that dx=dy (one-one aspect ratio)

Postscript

dumps out a postscript file

PWD
dumps out a list of the local directory

Copyright information

Quit
quit program

---------------------------------------------------------------

REFRESH

this is a button that simply re-draws the figure

---------------------------------------------------------------

Sources

* Plot Sources
Toggles the plotting of 1-st source file

* Color-Depths

plots the source with respect to depth with color Use the MaxDepth option in the Special menu to change the scale length. Events below MaxDep are not plotted.

Source Size

changes the size of the plotted events. Sources, by default, now plot according to their magnitude. See the scale in the corner. If you change the source size under the SOURCES menu, you simply increase/decrease the minimum source size plotted (min=Magnitude <=1). If the linear scale option is chosen (see below), you will have to input a slope parameter if you change the minimum source size. The slope is currently entered in the main command window.

Fancy Plot

make sources filled in instead of see-through.

Mag Scale

toggle using the magnitude to scale the source size. The minimum source size is controlled by the parameter Source Size mentioned above. (see Mag Options below)

Mag Options

toggle using the magnitude to scale the source size. The minimum source size is controlled by the parameter Source Size mentioned above. You have a choice of constant, exponential and linear scales.

Save Source

all the events selected in the last selection using the left mouse drag will be stored in a file determined by the environment variable XMA_SPE_SRC. This is a way to store special events that need to be plotted on various different displays. In a companion program called newsig, digital seismic data that is read in automatically stores the event locations in the file named by XMA_SPE_SRC so that Geotouch and newsig can communicate with each other. If you hit the <s> accelerator button you will see all the events stored in the XMA_SPE_SRC file.

Append Source

same as "Save Source" but it appends instead of over writing the file

Save Extensions

Instead of saving the hypocenter information you can save an extension from the end of the hypocenter card. This allows you to access digital data stored on your system by having the names of the files stored as extensions.

Set Disco

Used for setting DISCO parameters. see the DISCO documentation DISCO

SAVE FILE

Change the destination filepath for Save and Append commands, i.e. do not use the ENV variable setting. The SAVE_FILE may be changed any number of times. Each time a new file is created: if an older file with the same name is requested it is overwritten. Subsequent calls to SAVE or APPEND direct output to this new file.

* Src Output

Toggles the way the sources are printed when selected by the left button. Normal: The output created by the left-mouse selection of events is in A-card format, i.e. you may then cut/paste these into a file and restart Geotouch with them only. The output has time/lat/lon/magnitude and other information - in UW format. Furthermore I also dump out an "origin file" which (after cut/paste to a file) can be used in a close-up (zoomed) session of Geotouch. It is better to do this than keep zooming in with the ZOOM feature which creates many windows that are hard to manage. Connect: Events from the first Source File are selected from within the target, and they are connected to any sequentially matched events in other Source Files. Warning: Hypocenters are normally screened spatially to limit the number stored in memory. Normally, hypocenters located outside of the window surrounding the target are excluded. To force inclusion of all hypocenters into memory use the command line option "- force_source" This will force all hypocenters to be included (no spatial selection). This is important to use when applying the "connect" option on the Source menu. This option requires that the source files being connected have 1-1 correspondence.

No Src Output: Printing to the screen is suppressed. This is useful if you are making large selections to a file and you do not want the screen to page through them all.

Get More Sources

Gets a new file of source events.

* Plot More Sources

Toggles plots of all additional event files

* Connect Sources

connects the sources in sequence of input. Sources must have the same number of events in each file. (Otherwise there is no matching)

Layer-Source

Plot only those sources that fall within the displayed layer in an image. This is useful for tomographic stu- dies when you wish to see how seismicity is changing in each layer of a model.

Time Sources

this is a (defunct) button related to the plotting of time sequences

of sources.

Select Poly
select the events inside

Hypo Stats
provides basic statistics on

stored in the SAVE FILE, either the file specified by the ENV variable XMA_SPE_SRC, or otherwise changed. The stats are dumped to standard output. A wireframe file of the best fitting plane to the hypocenters is also created and can be accessed in file "hypo_plane" via the "Get 3D-Body" menu item under special.

Select DataBase

Select and plot only those events that comply with the Set Hypo selection rules

Reset DataBase

undo Select Database, i.e. plot all events.

Set Hypo

This is a database routine for selecting hypocenters based on typical parameters, time, magnitude, gap, err, etc....

---------------------------------------------------------------

Stations

* Plot Stations

Toggles the plotting of stations

* Plot Station Names

Toggles the plotting of station names

Station Size

* Geo Table

Plots out geological information (legend) defined in the Geo Map

Map Code

Set the code for plotting geological maps (e.g. a, abcdi, abcdefghi, etc...) Map elements that do not match the code string are excluded.

Sel Map

if geological type map is read in and left-mouse button has been made, this item will select from the map database all elements that intersect the target

Find Point

plot the points numbered of a selected map object

Points Map

plot the points of a selected map object

Dump Map

Dumps out a copy of the selected map elements to output file "dump_sel_map.out". This new map can be called in on subsequent Geotouch calls.

Lines Only

toggle drawing the geological map with just lines. This is useful if the geological map is confusing.

Add Lines

Add black lines around colored polygons.

LAT LON

will plot tic-marks every degree in lat and lon. Good for world and other large scale maps.

Outside Tics

plot tick marks on the outer edges of the plot.

Background Col

Cycle the background color of target region: grey, black, white. If some objects are hard to see, such as polygon drawing, this may be useful.

---------------------------------------------------------------

Vectors/Wells

Plot Wells

puts wells on the map and cross section plots. Wells are read in from an ASCII file. I have added a well plotting subroutine. This is similar to the Map routines: select the <Plot Wells> under the SPECIAL menu. type in the well-file name (wells.all on this tape). Voila, the wells appear. Note that you should select plot.well.names to see which are which. A description of the format and the programs I used to translate your files to my format are listed below.

Get Wells

Gets a file of vectors for plotting.

Plot Well Names

toggles whether well names should be plotted. Project Wells - projects the wells onto the horizontal map plot. (wells are projected onto the cross sections independently from this option).

Project Wells

plot the horizontal (surface) projections of 3D wells

Well symbols

toggles plotting the well symbols

Well in Layer

only plots the well parts that penetrate a particular layer. This option valid only when using images.

Xsec Project all

When plotting X-sections, plot the whole well That maps onto the cross section. The default is to plot only those portions that penetrate a cross-section block.

Increase Thickness

Increase the thickness of plotting the projected boreholes in cross section, Increments by 1 thickness unit.

Decrease Thickness

Decrease the thickness of plotting the projected boreholes in cross section

Legend

When plotting wells with color coded lithology, read in a file with a legend relating Geotouch colors to lithologic units in boreholes.

Dump Wells

dumpout the wells to standard output

Project Dips

plot the horizontal (surface) projections of dipmeter

information

---------------------------------------------------------------

Focals

Plot

toggle plotting of the focal mechanims

Get Focals

get a file with A and M cards (described below)

Sphere Size

minimum size for plotting a focal mechanism

Focal Style

one of several ways of plotting focal spheres, include beach balls, beach balls with P-T axis, just P-T axes, strike and dip projections, etc...Use (r,c,v,t) for acceleration

* Explode Focals

if balls are heavily concentrated, they will overlap. Can use this option to "explode" them so they do not overlap. Use (e) for acceleration.

* Magnitude Scale

toggle so that focal spheres are scaled by magnitude. The overall scaling is determined by Sphere Size above.

Color

the default is to color the focal according to rake. If this option is chosen, though, the focals will be colored according to input file. For one file input, this means all will have the same color. Each succes- sive file will be colored a different shade.

SDR
Dump out (stdout) last Focal mechanism selection (made previously with shift-left dragging) but also print out the Strike Dip Rake information. This appears on an extra line below the normal focal plane information (M-card) with the following character flag and floating point format:

SDR: DDAZ STRIKE DIP RAKE

Summary

All focal spheres within the most recent selection rectangle are summarized in the output window and a small figure showing the P and T axes projected on an equal area net is printed in the lower left corner. This plot is temporary and will disappear when the plot is refreshed. Reselecting the option will redisplay the plot.

PS Summary

Provides a postscript plot of the P and T axes plotted on the stereo-net described above.

Auto-Summary

Do summary plots and ternary diagrams in a grid over the whole plot region

Layer Foc

Plot only those focal mechs that lie within a given layer Used only if a 3D image is loaded

Reset Foc database

reset the selection to the initial setting

Set Focal

Set the focal selection flags

---------------------------------------------------------------

Contour

ContourField

read in a file of raw XYZ data in LAT-LON-Z for interpolation and contouring. The initial contour is done with default settings, but these can be changed by accessing the "Set Cont" button on the main panel.

Plot Contour
toggles whether to plot the contours or not (after they have been calculated)

Raster

Dumps out a 2D raster file suitable for plotting in Geotouch (-I file)

Dump Map

Set Cont

Pops up a panel for changing the contouring parameters. See following for parameters description.

---------------------------------------------------------------

Set Cont

These parameters control the handling of the surface fitting program and the contouring. If you click SET in this box a new contour plot is calculated with the new parameters. Grid: grid dimensions of contour area (taken originally from origin file)

Dx-Dy: number of grid points in X (DX) and Y (DY) directions to use in interpolation. Use this to get smoother or courser contours.

Aspect Ratio - set to 1.

Limits - 0

Max_iterations - 250

Tension - 0

X - 1.4

Contour Levels: number of contour levels. If this is a file name, the program will read in the contour levels from the file. Can use this to fix the contours at nice levels.

Scale Factor
multiply each point in field by this value.

SET
re-do the interpolation and contouring with new parameters.

Cancel
do not re-calculate contours.

---------------------------------------------------------------

Image

Skip Value

Change the value which is skipped in the image file

(missing values).

Z-Layer

Jump to a specific layer in the model

Top(layer 1)

Go Back to Layer 1

Palette

There are currently two available color palettes for plotting images and contour plots. This menu item toggles between these two.

Scale Lay/Glob

if selected this toggles between using a global scaling versus using a separate scaling for each layer of the model. This is useful when the image consists of dif- ferent units in each layer.

Log/Lin scale

Toggle between Log or Linear color scales for the image

displayed.

User min-max

the User can input a set of minimum and maximum values to use in scaling rather than the minimum and maximum values from the data. Values outside these regions are saturated into the bins of maximum value.

User Min

the User can input a set of minimum values to use in scaling rather than the minimum values from the data. Values outside these regions are saturated into the bins of maximum value.

User Max

the User can input a set of maximum values to use in scaling rather than the maximum values from the data. Values outside these regions are saturated into the bins of maximum value.

Export Layer

Dump a layer of the image to a file in ASCII

Reverse_Palette

Flip the palette to go from blue to red or vice versa.

New_Palette

Read in your own palette (not available yet).

Palette Info

Dumps information about the Palette to standard output

Integrate

First, select a polygon using the NewPolygon (Special menu) item and the control-left button click. Second, select this option: you will need to insert the minimum, maximum and a scaling factor (e.g. to convert meters to km: use 0.001). Those raster values that fall within these ranges inside the target are highlighted and integrated (summed using raster pixel size as dArea).

High_lite

After providing a min and max value, those values fal- ling between these extremes are highlighted and counted. Information is dumped to startup screen.

Save Target

Wire Render

First select a target region. After selecting this option the program queries for an upper and lower limit for pseudo-rendering. This feature will isolate all blocks within the limits and output a wire frame structure enclosing all blocks in the target region. Panels shared by adjacent blocks are eliminated. The out put is currently dumpped to two files that must be conctonated together. Use unix command:

cat dumpit_wire_frame_top dumpit_wire_frame > new_wireframe

This new wire frame structure, in file "new_wireframe"

can then be used immediately in the current Geotouch session. Use the "Get 3D-body" under Special to access the new wire frame structure.

Image Info

Dumps out to startup screen information pertaining to the image read in.

Dump RGB

Dump out RGB values for a selected part of the model

Postscript All Lay

Create individual postscript files for all the horizontal layers of the current 3D image.

Satellite

Toggles plotting of satellite image. This image is read in on the command line at start up so the colormap can be calculated and adjusted.

Shift Satellite

This will shift the satellite image in the plane to match it with other map elements.

Get File

This is an experiment that is still in progress. Does nothing at this point, but may crash the system.

---------------------------------------------------------------

X-Secs

Depth Range

changes the maximum and minimum depth for scaling the color depth and selecting events on the vertical cross sections.

HalfWidth

changes the swath used for selecting vertically pro- jected earthquakes on the cross sections

* Plot X-Secs

toggles whether to plot the cross sections in plan view on the map display.

SAVE X-Secs

save Cross section information to a file for later use (file="SAVE_xsecs")

Load X-Secs

reads in a file of lat-lon pairs for pre-set cross sec- tions. Cross sections can now be stored and read in from a file. As you make a new cross section, the stan- dard output reports on the lat-lon/lat-lon of your cross-section. Just put these (via cut/paste) into a file and read it in from the LOAD X-sects under the SPECIAL menu. example:

36.113754 -117.877953 35.952969 -117.736397 0.0 0.00 10.00 1.00 1.00

lat lon lat lon dip top bot front back

Set X-secs

Input cross section parameters on the screen during run time

Set XDip

Pops up a panel for changing the cross section parameters

---------------------------------------------------------------

Special

Restore Size

restores from a Zooming session.

Postscript

dumps out the plot to a postscript file. To use this option the postscript header is required (included). Place the header file in a convenient directory and type in at the UNIX prompt:

setenv PSHEAD <your-directory>

NOTE: Most toggle switches also toggle the postscript output file, i.e. if the names for stations, wells or what ever are turned off/ they will appear in the postscript output accordingly. I have added cross- section postscript file creation. You can create any number of postscript files as long as you call them by different names. You may view a postscript file at any time by running pageview from a separate command window on the file you just created.

* BLACK/WHITE

toggles whether postscript output will be in color or black and white.

Dump Colors

List out the current set of colors. These may be changed by saving them in a file and modifying the color palette.

Plot Targets

Toggles the plotting of target regions already selected. Plotting target regions help remind one of areas that have been considered in detail.

Erase Targets

Starts the target counter over so that previous targets are lost.

New Polygon

reset the polygon so it has no points. Polygons can be drawn by using the meta-Left-mouse clicking action. (Hold down the meta or control-key and click with left mouse. Polygons are currently not postscriptized, however if you select "Replot Poly" the polygon is dumped to stdout as lees-format map stroke which can be read in again and plotted in postscript.

Spline

smooth the last polygon so it does not have sharp corners. Values are dumped to screen and can be cut and pasted for later use.

Replot Poly

Replots the last polygon selection

Replot Target

Replots the last target selection

Get 3D Body

get a wireframe object from a file (see below)

Plot 3D Body

toggle the plotting of the wireframe objects

Hoz Slab

Only WELLS located within the depth range provided are plotted. This is a useful option for plotting selected layers of Wells from 3D rasters of vectors

Spin Events

Pops up a new window for spinning earthquake hypo- centers that are selected in a target.

---------------------------------------------------------------

Misc

Restore Size

Restore figure to the original dimanesions (same as in the File menu)

Store Points

Save the points to a file for later use.

Create Label

Dialogue box for inserting label text. Use the m-n keys to locate the the label and the arrow head.

AFTER you select label and insert the text and click OK you need to hit first "m" then "n" (the help window says this to remind you, also the little dialogue box reminds you of this).

m sets the tail, and n the head, of the arrow. the label is placed on the tail. After you place the tail (the label) you can move the arrow with successive "n" typings. However, if you hit "m" you must hit "n" again to finilize the pointer.

Reset Label

Change the text of the current label

Save Labels

Puts all labels into a file for later use or editting.

Get Labels

Restores labels from a file previously stored by the Save Labels command.

---------------------------------------------------------------
