Import *.TXT Coordinates
Since the coordinates in an ASCII *.TXT file can be stored in a variety of formats, two screens are used to define the
format of the file that is being imported once a layer is selected. The source *.TXT file can contain either plane
coordinates or geodetic coordinates.
Delimiters: is the character that separates each column of text in the ASCII file.
Units: are the units that the distances in the file were stored in.
Coordinates: is used to specify if the coordinates are plane coordinates, geodetic coordinates in degrees-minutes-
seconds format, or geodetic coordinates in decimal format.
Skip the first row: should be checked if the first line in the ASCII file contains non-coordinate information, such as a
heading.
[Next >]: opens the second screen .
Import *.TXT Coordinates – Screen Two
[> Name Column No.] / [> Start Point Name]: When the first option is selected here, the column number used for
the name field in the *.TXT file is specified here. When the second option is selected, it is assumed that the *.TXT file
does not contain point names and will assign the first point the name specified here and increment to the next available
point name for the remaining points.
Columns: is where the column number for each specified coordinate exists in the source *.TXT file. The coordinates
types displayed here can either be for plane coordinates or geodetic coordinates depending on the selections made in
the previous screen. If a coordinate has a checkbox, which is unchecked, it is assumed that the source *.TXT file does
not contain columns for that type of coordinate.
Specify Missing Elevation Threshold: if the source file was created from coordinates with no elevations, but the file
contains an elevation column with values, such as 0, check this box and indicate the value in the field that will appear
to the right.
[Preview]: opens the ASCII Import Preview window containing all the point data that will be imported. This is useful
to check for errors before actually importing new data.
[< Back]: returns to the previous screen .
[Finish]: imports the new point data into the current project.
Import LandXML Coordinates
Points, alignments, polylines, and parcels can be imported from a LandXML file.
The way the LandXML data is imported depends on how the data is stored in the source file and how the settings are
configured in the screens described here.
Consult the User’s Manual for more information on the conditions that affect how the data is imported.
