• Grid: This point’s local grid coordinates are the Northing, Easting, Elevation values
that were keyed in or imported. This point’s global geodetic coordinates will be
calculated by transforming grid coordinates into latitude, longitude, height
coordinates using the current projection.
• Global geodetic: This point’s WGS84 coordinates are the latitude, longitude and
height values that were keyed in or imported. This point’s local grid coordinates
will be calculated by transforming geodetic coordinates into Easting, Northing,
Elevation coordinates using the current projection.
• Local geodetic: This point’s local geodetic coordinates are the latitude, longitude
and height values that were keyed in or imported. This point’s grid and global
geodetic coordinates will be calculated by transforming the local geodetic
coordinates with the current projection.
When there is no projection set or solved, there is no way to transform the keyed in
values into grid or geodetic coordinates. You will see these coordinates are missing
when you look at the point details.
If this point is derived from an observation, the Location tab will list its current
coordinates but these cannot be edited.
For more information on Descriptions, Layers and Features, see Appendix on page 73.

Polylines
A polyline in Survey Pro is a line connecting points together. Each vertex of the line
is defined by an existing point, whether an observed or keyed in point. Points in
polylines can be connected with either straight segments or horizontal curves.
You can use the polyline editor to modify polylines (go to Job > Edit Polylines). The
polyline editor is described in the Online Help.
Editing
Alignments
An alignment in Survey Pro is a line defined by vectors starting at a Point of Beginning
(POB). The POB can be an existing point in the job, or just location coordinates.
Alignments can have horizontal segments and optionally a vertical profile. Horizontal
segments can be straight segments, circular curves or spiral curves. A vertical profile
can be defined using a vertical curve and straight grade segments.
You can use the alignment editor to modify alignments (go to Job > Edit Alignments).
The alignment editor is described in the Online Help.
You can import alignments for staking, using Roads > Edit Roads menu. Alignments
imported using this function can be viewed in the alignment editor but cannot be
modified.
Exporting
Data
Use the File > Export function to export data from the open job to one of the supported
file formats. For most formats (Survey, JOB, TXT, CSV, XML, CR5 and DXF), you may
select the portion of the current job you wish to export. For export to Survey Pro 4.x
(Job/RAW) or JobXML format, the entire job database will always be exported.
