Cogo Editor tool
Used to create parcel maps from boundary descriptions recorded in official deeds. The Cogo Editor also provides for on-screen digitizing and tools for maintaining, modifying, and retrieving both graphic and non–graphic information comprising the parcel map and associated tax records.
A deed file is a data file that contains the metes and bounds describing a parcel of land. These files can be created by any text editor that creates ASCII files. When opened by the Cogo Editor, deed files provide the input necessary to create parcel descriptions. They can also be created by entering the metes and bounds of a parcel into the Cogo Editor. Cogo Editor automatically draws the parcel in the design file, saves the parcel geometry to a database, and labels the parcel as defined. This data can be permanently stored in an ASCII file and opened for subsequent editing and/or placement in the Cogo Editor.
While creating deed files with the tools in the Cogo subsystem is recommended, it is possible to create ASCII deed files through other means, such as an export procedure from other software or a conversion program to modify existing deed records into a format usable by the Cogo Editor. The ASCII file format recognized by Cadastral Mapping Configuration is roughly modeled on standard Cogo Editor statements without implicit point number references. All measurements should be specified in feet. Lengths are converted upon file input. For metric users, if normal engineering units are meters, specify all units in meters and do not select the meters unit conversion option.
The individual command lines or edge call formats are as follows.
- A straight edge — Locate Bearing command
LOC TRAV DIS ddddd.dd bearing_string
where ddddd.dd is a positive numeric distance and bearing_string is an angular bearing measurement in the form: N|S dd mm ss.ss E|W where dd = positive degrees (00–90), mm = positive minutes (00–59), and ss.ss = positive seconds (00–59.99).
- A curved edge — Tangent Arc command
STO CURV sweep RADIUS ddd.dd LEN lll.ll
where sweep = CL for clockwise and CC for counterclockwise, ddd.dd = positive arc radius, and lll.ll = positive arc length.
- A curved edge — Non-tangent or chord curve command
CHORD CURV bearing_string distance sweep radius
where bearing_string = standard angular bearing (see above for format), distance = positive bearing distance, sweep = CL | CC, and radius = positive arc radius.
- A straight edge — Tangent Line command
POT TL distance
where distance = tangent length from preceding arc.
- A straight edge — Deflection Line command
LOC DEF direction angle distance (for forward sight)
LOC ANG direction angle distance (for back sight)
where direction = L for left, R for right, angle = deflect angle in the form: dd mm ss.ss where dd = positive degrees (00–90), mm = positive minutes (00–59), ss.ss = positive seconds (00–59.99).
- Parcel identification number
Parcel_Identifier = id
where id = alphanumeric parcel ID (most commonly referred to as a PIN number).
