What Does The 'PLS Tool'
Do?
|
|
The PLS Tool includes a large
database that describes the circumference of every section in
the state. Data is collected from government sources, and
supplemented with hand digitized coordinates from the 1:24,000
scale USGS quadrangles.
Once installed in a state's 'ALL TOPO
MAPS:V7 Professional Map Reference Set', the PLS Tool is enabled by selecting the 'View' menu,
then 'Display Township Range Section' on the view menu:
A new display field will appear on
the toolbar of the 'ALL TOPO MAPS:' application window.
PLS TOOL Display Field Example:
ALL TOPO MAPS: V7 PRO Application Window Example Above.
As The Cursor Is Moved Over The
Map, The Current PLS Coordinate Is Displayed In The PLS
Field.
Double-Click On The PLS Coordinate
Field, To Change The Coordinate Display Format:
Choosing 'Offset
from South East Corner' yields a footage offset from the
South East corner:
Press Ctrl-Z to
copy the PLS description '1303W 1799N from SE Sec 19 T
23N R 6E PM New Mexico' to the Window's Clipboard (for
insertion into another document).
New Find PLS Coordinates:

What Is PLS?
|
|
In 1796, The United States Congress Enacted A Method Of Dividing
Public Domain Lands Into Theoretical Six Mile Square Units Known
As ?Congressional Townships?. Townships Are Based From A Central
Set Of Orthogonal Axis; The North-South Axis Is Called The
?Principal Meridian?; The East-West Axis Is Called The ?Base
Line?. Townships Are Consecutively Numbered To The North-And-South
And Ranges Are Numbered From East-To-West.
Each Township is divided
into a six by six grid of 1 mile squares called sections.
Sections are numbered in a serpentine fashion from the North
East corner of the township. If perfect, each section would
encompass 640 acres. Sections are additionally divided in to 160
acre quarters, and then into 40 acre quarter quarters.
Since the meridians and
base lines are not truly parallel, no townships are perfectly
square. Where different axis meet there are very significant
errors. Early surveying errors added additional imperfections.
In spite of all the
errors, the Public Land Survey system still accurately defines a
point-on-the-ground or parcel by Principal Meridian, Township,
Range, Section and offset.
The various scales of
topographic maps have traditionally shown sections and
townships. On a released 7? minute quadrangle, township and
range are identified in the map collars.
When using traditional
digital products, it is difficult to pan to the edge of a map
and find the Township and Range for a given section.
Many digital products de-collar the maps (these are called
"seamless maps"), which makes determination of Township and
Range impossible.

MAPS:' Provides The Actual USGS
DRG Maps!
"Seamless" Map Image - Incomplete/Useless/Difficult-To-Work-With
Most 'All Topo Map'
standard edition state sets are searchable by Township and
Range. This makes viewing the map that
contains a Township/Range/Section coordinate very easy.
The All Topo Maps: PLS Tool adds a huge database of section
information and provides real-time-display of the cursor?s
position to ? ? section, or as a footage offset from a section
corner. Displayed cursor PLS coordinates can be
copied directly to the Window?s Clipboard for subsequent pasting
to other applications. The PLS Tool also adds searching by
Township / Range / Section for quickly finding and annotating
features by legal coordinate.
While not accurate enough for survey or land division, the PLS
Tool is great for locating maps and determining / displaying
approximate legal coordinates.
