NAME

+ +cs2cs - cartographic coordinate system filter + +

SYNOPSIS

+ +cs2cs + +[ +-eEfIlrstvwW + +[ +args + +] ] [ ++opts[=arg] + +] +
+ +
[ +to [+opts[=arg]] ] +file[s] + +

DESCRIPTION

+ +Cs2cs + +performs transformation between the source and destination cartographic +coordinate system on a set of input points. The coordinate system +transformation can include translation between projected and geographic +coordinates as well as the application of datum shifts. +

+ +The following control parameters can appear in any order: +

-I + +: +method to specify inverse translation, convert from +to coordinate +system to the primary coordinate system defined. +
-ta + +: +A + +specifies a character employed as the first character to denote +a control line to be passed through without processing. +This option applicable to ascii input only. +(# is the default value). +
-e string + +: +String + +is an arbitrary string to be output if an error is detected during +data transformations. +The default value is: *\t*. +Note that if the +-b, + +-i + +or +-o + +options are employed, an error is returned as HUGE_VAL +value for both return values. +
-E + +: +causes the input coordinates to be copied to the output line +prior to printing the converted values. +
-l[p|P|=|e|u|d]id + +: +List projection identifiers with +-l, + +-lp + +or +-lP (expanded) + +that can be selected with ++proj. + +-l=id + +gives expanded description of projection +id. + +List ellipsoid identifiers with +-le, + +that can be selected with ++ellps, + +-lu + +list of cartesian to meter conversion factors +that can be selected with ++units + +or +-ld + +list of datums that can be selected with ++datum. + +
-r + +: +This options reverses the order of the +expected input from longitude-latitude or x-y to latitude-longitude or y-x. +
-s + +: +This options reverses the order of the +output from x-y or longitude-latitude to y-x or latitude-longitude. +
-f format + +: +Format + +is a +printf + +format string to control the form of the output values. +For inverse projections, the output will be in degrees when this option +is employed. +If a format is specified for inverse projection the +output data will be in decimal degrees. +The default format is "%.2f" for forward projection and DMS +for inverse. +
-[w|W]n + +: +N + +is the number of significant fractional digits to employ for +seconds output (when the option is not specified, +-w3 + +is assumed). +When +-W + +is employed the fields will be constant width and with leading zeroes. +
-v + +: +causes a listing of cartographic control parameters tested for and +used by the program to be printed prior to input data. +

+ +The ++args + +run-line arguments are associated with cartographic parameters +and usage varies with projection and for a complete description see +Cartographic Projection Procedures for the UNIX Environment---A User's Manual ) + +and supplementary documentation for Release 4. +

+ +The cs2cs program requires two coordinate system definitions. The +first (or primary is defined based on all projection parameters not +appearing after the +to argument. All projection parameters +appearing after the +to argument are considered the definition +of the second coordinate system. If there is no second coordinate system +defined, a geographic coordinate system based on the datum and ellipsoid of +the source coordinate system is assumed. Note that the source and destination +coordinate system can both be projections, both be geographic, or one of +each and may have the same or different datums. +

+ +Additional projection control parameters may be contained in two +auxilliary control files: +the first is optionally referenced with the ++init=file:id + +and the second is always processed after the name +of the projection has been established from either the run-line +or the contents of ++init + +file. +The environment parameter +PROJ_LIB + +establishes the default directory for a file reference without +an absolute path. This is also used for supporting files like +datum shift files. +

+ +One or more +files + +(processed in left to right order) +specify the source of data to be transformed. +A - will specify the location of processing standard input. +If no files are specified, the input is assumed to be from +stdin. + +For input data the two data values must be in the +first two white space separated fields and +when both input and output are ASCII all trailing portions +of the input line are appended to the output line. +

+ +Input geographic data +(longitude and latitude) must be in DMS format and input +cartesian data must be in units consistent with the ellipsoid +major axis or sphere radius units. +Output geographic coordinates will be in DMS +(if the +-w + +switch is not employed) and precise to 0.001" +with trailing, zero-valued minute-second fields deleted. + +

EXAMPLE

+ +The following script +

: +
cs2cs +proj=latlong +datum=NAD83 + +to +proj=utm +zone=10 +datum=NAD27 -r <<EOF + 45d15'33.1" 111.5W + 45d15.551666667N -111d30 + +45.25919444444 111d30'000w + EOF +

+ +will transform the input NAD83 geographic coordinates into NAD27 coordinates +in the UTM projection with zone 10 selected. +The geographic values of this example are equivalent and meant +as examples of various forms of DMS input. +The x-y output data will appear as three lines of: +
