Edit Point Groups
The Edit Point Groups feature allows you to use the CGEditor to
edit/create an existing point group file.
CGEditor General
Information
The CGEditor is an integral part of preparing files for use in
C&G applications. The CGEditor is a very powerful
tool. You can open multiple data files of any supported file
type and edit the files as needed. The CGEditor has a full
complement of tools for searching and replacing and navigating
within a file. It will also allow you to cut or copy records
from one file and paste them into another file in order to merge
files, move data between phases of a job, etc.
The CGEditor can create and/or edit six types of data files
used by C&G:
Raw Data Files
Raw data files contain information pertaining to a field
traverse. Raw data files are typically downloaded from the
data collector and converted to the C&G raw data file
format. These files have the extension .CGR.
Map Check Files
Map Check files contain bearing, distance and curve information and
are typically used to calculate the closure of a deed
description. These files have the extension .CGM.
Cross Section Files
Cross Section files contain one or more cross sections identified
by their station along the alignment. Each cross section
record has the percent grade defined for its left and right
slopes. Following the “Station” record are several “Point”
records containing the elevations and offsets of the points along
the cross section. Cross section files consist of a pair of
files; the main data file has the extension .CEW and the index file
has the extension .CEX.
Template Files
Template files are merely cross section files that represent a
standard cross section and can be used to generate other cross
section files. However, unlike cross section files, template
files use an integer ID instead of a station to uniquely identify
each template. Like cross section files, the percent grade is
defined for the left and right slopes of each template and there
are a set of “Point” records specifying the template elevation at a
given offset. The centerline elevation at offset 0.00 is
typically set to 0.00. Template files consist of a pair of
files; the main data file has the extension .CTP and the index file
has the extension .CTX.
Point Group Files
Point Group Files are simply a list of point numbers that can
define a group of points, a lot or parcel, or an alignment. These
are ASCII files and have a .PTS extension.
Coordinate Files
CGSurvey supports many different coordinate file
formats:
C&G .CRD/.IDX - C&G numeric coordinate files
C&G .CGC/.CGX - C&G alpha-numeric coordinate files
Carlson .CRD - Carlson coordinate file format, numeric and
alpha-numeric
Simplicity .ZAK - Simplicity coordinate file
LDT - MDB - Land Desk Top coordinate file
