.SH DESCRIPTION
\fBlasblock\fR displays LAS file details with optional
output filters.
While \fBlasblock\fR can do a few simple operations like
updating header information, more drastic changes, like removing points
or altering values, will require
\fBlas2las\fR(1).
.SH OPTIONS
.TP 
\*(T<\fB\-h\fR\*(T>, \*(T<\fB\-\-help\fR\*(T>
Produce help message
.TP 
\*(T<\fB\-c\fR\*(T> \fIarg\fR, \*(T<\fB\-\-capacity\fR\*(T> \fIarg\fR
Number of points to nominally put into each block
(note that this number will not be exact).
Default: 3000
.TP 
\*(T<\fB\-p\fR\*(T> \fIarg\fR, \*(T<\fB\-\-precision\fR\*(T> \fIarg\fR
Number of decimal points to write for each bbox. Default: 8
.TP 
\*(T<\fB\-i\fR\*(T> \fIarg\fR, \*(T<\fB\-\-input\fR\*(T> \fIarg\fR
input LAS file
.TP 
\*(T<\fB\-o\fR\*(T> \fIarg\fR, \*(T<\fB\-\-output\fR\*(T> \fIarg\fR
The output .kdx file (defaults to input filename + .kdx)
.TP 
\*(T<\fB\-v\fR\*(T>, \*(T<\fB\-\-verbose\fR\*(T>
Verbose message output
.SH EXAMPLE
Block a file, and write out blocks with 6 decimals of precision with a
nominal capacity of 3000 points per block:

.nf
\*(T<
lasblock \-c 3001 \-p 6 myfile.las
      \*(T>
.fi
.PP
\fBNote\fR. 
If no capacity is specified with \*(T<\fB\-c\fR\*(T>,
\*(T<10000\*(T> is assumed.
.PP
\fBNote\fR. 
\fBlasblock\fR will always write out a
\*(T<\fImyfile.las.kdx\fR\*(T> file name by default,
but you can override the output name with a
\*(T<\fB\-o\fR\*(T> command-line switch.
