Spectra Precision Survey Pro v4.9 - Manual (Page 9)

The Import screen is used to add the points from another source into the current job or import the data from a
LandXML file to the current job.
Warning : Coordinate values can change when they are imported!
Importing coordinates from any source other than a *.JOB file requires that the distance units used in the source file be
specified. It is not necessary to specify the distance units when importing coordinates from a *.JOB file since those
units are written within the file.
If importing coordinates where the distance units in the source file are different than the distance units for the current
job, the imported coordinates will be converted to the current job’s distance units when they are imported. This is
normally the desired result, but it can cause a problem if any distance units were set incorrectly. This situation can
most commonly occur when working with International Feet and US Survey Feet where the conversion from one to
the other is not always obvious.
Usually the difference between International Feet and US Survey Feet is negligible (2 parts per million), but when
dealing with State Plane or UTM mapping plane coordinates, which are often very large in magnitude, the difference
can be substantial if the coordinates are converted from one format to the other.
If importing coordinates from a source, such as an HP 48, where you are not sure if the units are in International Feet
or US Survey Feet into a job that is set to International Feet or US Survey Feet, you will usually just want to import
them without any conversion being performed. To do this, be sure to select the same distance units for the source file
as those set for the current job.
Coordinates from a variety of file types can be imported into the current job. The first Import screen is used to select
from the file types listed below. The next screen that opens depends on the selection made here.
Job Files (*.JOB): import coordinates from another Job file.
Coordinate Files (*.CR5): import coordinates from a CR5 coordinate file.
GPS Files (*.GPS): import coordinates from a GPS coordinate file.
Text Files (*.TXT): text files can contain coordinates in several different possible formats. The Import ASCII
Wizard is used to define the format of the text file being imported.
Text Files (*.CSV): this is a simplified text file import routine where the source file is comma delimited and has
a *.CSV extension.
LandXML Files (*.xml): imports points, alignments, polylines, and parcels from a LandXML file.
Import *.JOB Coordinates
When importing coordinates from another *.JOB file, the Import screen is used.
A list of all the jobs available in the current directory is displayed. Simply tap on the job name that you want to import
and then tap
the
button. The points in the selected job will be added to the points in the current job.
Import *.CR5 Coordinates
The Import CR5 screen will open when importing coordinates from a *.CR5 coordinate file after selecting a layer.
Simply select the distance units that the coordinates were stored in and tap
.
