+eheader - display and modify headers of EPPL7 data files
+
+eheader options files
+maplist files
+mapalign base_file [-v] files
+
+Applies given editing commands to list of epp or dgt files.
+Several commands
+are applicable to both file types and several to epp (raster) files only.
+No warning is issued when dgt file is processed during section when epp-specific
+commands used, becouse several epp-files can be processed at same time.
+
+No warning is issued also when no editing commands given, therefore this
+utility can be used just for viewing header information.
+When invoked as
+maplist, simply dumps headers of given files.
+when invoked as mapalign
+performs same operations as with -A key, but only other option accepted
+is -v. This option may be given as before, as after base file.
+
+
+
+This commands can be applied to both dgt (vector) and epp (raster)
+files.
+
+
+- -v
+- - dumps file header information after applying any edit options
+to stdout.
+
+
+
+
+
+- -x increment
+- - shifts alternative x by increment. Increment
+can be any real number, both positive and negative.
+
+- -y increment
+- - same
+with alternative y
+
+- -s factor
+- - multiplies all coordinates by factor
+
+
+This
+commands cannot be used together with explicit settings of some alternative
+coordinate limit.
+
+
+- -Xl value or -XL value
+- - sets alternative x of left border
+to specified value
+
+- -Xr value or -XR value
+- - same with right border
+
+- -Yb value
+or -YB value,-Yt value or -YT
+- - same with bottom and top y
+
+- -p name
+- - set
+projection type to name. Available projection types ( EPPL7 version 3.0
+) are:
+
+- none
+- - cause EPPL ver 3 to say "No alternate coordinates"
+
+- utm
+or UTM
+- - UTM projection
+
+- stplate
+- - state plane (projection for US state
+maps)
+
+- ll
+- - latitude and longitude (geographic coordinates)
+
+
+
+
+Following is applicable to EPP files only:
+
+
+- -o n
+- - set offsite
+value to n. Value can be in range -32768 65535. Negative values are equivalent
+to 65536-abs(n). Values above 255, applied to 8-bit data files are silently
+translated into -1 (no offsite)
+
+- -fr n
+- - set first row to n and updates
+last row field respectively.
+
+- -fc n
+- - set first column to n and updates
+last column field.
+
+- -A filename
+- - align to specified file, i.e updates row/column
+coordinates so row and column with same number have same alternative coordinates.
+
+
+- -a value
+- - set cell area to value.
+
+- -c "string"
+- - fills description field
+of the header. String must be single command line argument, but not nessecary
+need quotes.
+
+- -u name
+- - set area unit type, where unit type may be:
+
+- none
+
+- - cause EPPL ver 3 to say "No alternate coordinates"
+
+- ft
+- - square feet
+
+
+- m
+- - square meters
+
+- km
+- - square kilometers
+
+- mile - square miles
+
+
+- ha
+- - hectares
+
+
+- acre
+- - acres
+
+
+This command does not perform any recalculation, it just
+update unit name field. Use -a command for change cell area value respectively.
+
+
+
+Some options of eheader cannot coexist together
+in same command line. there are two groups of options with incompatibilities
+between subgroup of each group.
+ First, options dealing with alternative
+coordinates. There are options -Xl -Xr -Yt -Yb, which set alternative coordinates
+explicitely, and options -x -y -s, which change coordinates by arithmetic
+calculations. Explicit and arithmetic changes of coordinates are not allowed
+simulateneously, becouse it is to hard to understand, which kind user
+want to apply first.
+ Second, options dealing with row/column coordinates
+of epp files. Here there are options -A and -fr -fc which performs directly
+opposite task. (usially -fr -lr are used to set first row and column to
+one, to process file cutted from large file separately and -A to change
+it back to mosaic(1)
+ file into larger one.
+
+
+lessa(1)
+, mappaint(1)
+,
+mapcopy(1)
+ epp(5)
+, dgt(5)
+
+
+No check is performed by -fr and -lr command
+to ensure that row/column values are in valid range.
+-A command sometimes
+miscalculates one cell. (but EPPL ver 2.1 does the same).
