NAME

+eheader - display and modify headers of EPPL7 data files +

SYNOPSIS +

+eheader options files

+maplist files

+mapalign base_file [-v] files +

DESCRIPTION +

+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.

+

+ +

UNIVERSAL +OPTIONS

+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)
+
+ + +

EPP SPECIFIC +COMMANDS

+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. + + +

OPTION COMPATIBILYTY

+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.

+ +

SEE ALSO

+lessa(1) +, mappaint(1) +, +mapcopy(1) + epp(5) +, dgt(5) + +

BUGS

+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). +
