GRASS 4.1 U.S. Army CERL 3 <br /> v.in.arc <alpha> GRASS Reference Manual <alpha> v.in.arc <br /> > <br /> IMPORTING A POLYGON COVERAGE <br /> If the user chooses POLYGON coverage, he is asked if he <br /> wishes a neatline placed around his data. (The existence of <br /> neatlines in the output file can facilitate subsequent <br /> patching of data files.) <br /> NEATLINE <br /> Do you want a neatline ? <br /> Enter "yes" or "no" <br /> > <br /> If the user types yes, vectors that box the data will be <br /> inserted into the GRASS vector output file (vector_out); <br /> otherwise, no neatline will be inserted into the output <br /> file. <br /> Next, the user is prompted for the name of an existing <br /> lines-file containing the geographic coordinates of the arcs <br /> forming polygon perimeters. The lines-file is created with <br /> the ARC/INFO Ungenerate LINES option, and is in the same <br /> format at the prefix.pol file created by the v.out.arc <br /> program. The user sees the following prompt: <br /> LINES FILENAME <br /> Enter name of the file created with the LINES <br /> option of the ARC/INFO Ungenerate command. <br /> Hit RETURN to cancel request <br /> > <br /> The next prompt for coverage type "polygon" asks for the <br /> name of an existing label-points file. The label-points <br /> file is created with the Ungenerate POINTS option, and is in <br /> the same format as the prefix.lab file created by the <br /> v.out.arc program. The user sees the following prompt: <br /> LABEL-POINTS FILENAME <br /> Enter name of file created with the POINTS <br /> option of the ARC/INFO Ungenerate command. <br /> Hit RETURN if there is no such file <br /> > <br /> Finally, the program asks the user for the name of an <br /> existing label-text file. This file associates each label- <br /> point ID number with a text string. It is in the same <br /> format as the prefix.txt file created by the v.out.arc <br /> program. <br /> LABEL-TEXT FILENAME <br />Page 8 <br />01/03/97 2.03-02 - Lange <br />
