Topic:
Data Input/Output - What files can be read and what can be written in MapView?

Description:
        

Solution:
READ DATA       SOURCE   OPTION                     FILE        MapView
                                                   CREATED      Updated

horizon time    IESX     select horizon(time)       binary        yes
horizon amp.    IESX     select horizon(amp)        binary        yes
fault time      IESX     select fault               binary        yes
fault trace     IESX     select horizon(time)       binary        yes*



horizon time    BINARY   select horizon(time)       none          yes**
horizon amp.    BINARY   select horizon(amp)        none          yes**
fault time      BINARY   select fault               none          yes



horizon time    BINARY   Read XYZ data              none          yes***
horizon amp.    BINARY   Read XYZ data              none          yes***
fault time      BINARY   Read XYZ data              none          yes***



Grid data       BINARY   Read grid data             none          yes***
Contour data    BINARY   Read contour data          none          yes***



XYZ data        CARD     Read XYZ data              none           yes
Grid data       CARD     Read grid data             none           yes
Contour data    CARD     Read contour data          none           yes



*Note: Fault traces may be input to MapView only if defined in IESX. IESX fault
traces are referenced by both horizon and fault. All fault traces for a given
horizon are accessed with the horizon time data. Fault traces may be
interactively defined in MapView and written into IESX.

**Note: These items refer to the situation where the user decides to access the
same IESX horizon or fault data for a second time. The data will actually be
read from the binary file files created when the user initially asked for this
data. 

***Note: You may access the binary files directly using the option to read XYZ,
Grid, or Contour data. The binary file names will appear on the list along with
any card files that have been created. Binary files contain header information
about the existence of the other files for the same surface. If you load a
binary XYZ file, MapView will also laod the Grid and Contour binary files for
that surface automatically, if they exist. Grid and contour files laoded in this
way will write over the current grid and contours residing in MapView.



WRITE DATA         SOURCE       OPTION               FILES       MAPVIEW
                                                    CREATED      UPDATED

data points        MapView      Write XYZ data       card         none
grid data          MapView      Write Grid data      card         none
contour data       MapView      Write Contours       card         none


data points        MapView      Update MapView IESX  none         binary
grid data          MapView      Update MapView IESX  none         binary
contour data       MapView      Update MapView IESX  none         binary
fault trace        MapView      Update MapView IESX  none         binary



surface cuts       MapView      Save Surface cuts    none         IESX
fault trace        MapView      Update fault traces  none         IESX *


*Note: Fault traces, from MapView, may only be added to IESX if the surface
currently exists as a horizon in IESX.

The MapView output options called WRITE will create card format files. The
options labeled UPDATE will cause only binary files to be updated or created.
