Introduction of Township Survey

Similarly, A project on township survey or city surveying. Likewise, Involves proper Collaboration of all types of development work necessary for the Municipality or city. But aslo, It entails the Execution of the following systems:

  • Street system
  • Property lines
  • Water supply system
  • Sanitary system
  • Electrification system
  • Telephone system

In fact, the case of a newly Growing township survey or the Alteration of one in existence for some time. Specifically, You should clearly work out a plan for development to Appropriately extend the Amenities provided in the master plan.

Township Survey Company in BD

Conduct a project survey for the township to prepare maps regarding the following:

  • Topography
  • Street survey
  • Property demarcation
  • Water supply
  • Sanitary system
  • Electrification system
  • Telephone system

Moreover, We will describe the procedure for preparing these maps later. However, The development authority of the city or town conducts all the surveys. In fact, Cooperation with concerned departments like the Roads Department, Municipality or Corporation, Electric Supply Department, Telephone Department, etc.

Indeed, the Public Land Survey System (PLSS), we generally refer to township survey by a number. A Citation to the township will look something like this. Likewise, We use Markings like ‘Township 2 North Range 3 East’ or ‘T2N, R3E’ in property descriptions based on the PLSS.”


The United States General Land Office Initially surveyed and platted Township Surveys. They used Employed private survey crews to mark these surveys on the United States Geological Survey maps of the United States.

Township Survey Details

Specifically, Township survey are normally a square Roughly six miles (9.7 km) on a side with Essential Borders. Furthermore, Conforming to meridians and parallels, containing 36 sections of one square mile (2.6 km2) each. 

But also, They designate the northern and westernmost tier of sections in each township to accommodate. The convergence of the east and west township boundary lines or range lines.

 As well as any error in the survey measurements. Therefore these sections vary slightly from being one square mile or 640 acres (260 ha).  Survey townships exist in some form in most states other than the original 13 colonies, Kentucky, Tennessee, Vermont, and Maine.

But also, They create irregular or fractional township survey with fewer than a full 36 sections. In fact, areas where existing senior boundaries prevent the layout of full townships. Such as Spanish/Mexican ranchos, Indian reservations, state boundary lines, etc.

About Township Survey

Moreover, This kind of township survey is similar to geographic townships in the province of Ontario, Canada.
Indeed Kentucky, they divide the Jackson Purchase area (west of the Tennessee River) into townships and ranges.


In Tennessee, they survey the entire state into townships and ranges, which together form 13 survey districts managed by the Tennessee State Survey. Indeed the far northern region of Maine, they divide an area into townships and ranges oriented to true north.


In the central part of the state, they divide a region comprising 17 surveys into townships. Yet, these townships do not align with true north. The remainder of the state is on metes and bounds. ermont and New Hampshire, which are primarily metes-and-bounds states, also feature regions in the north that have townships surveyed without orientation to true north.


The majority of Ohio is surveyed using the Public Land Survey System. But also, there are several substantial areas that follow metes-and-bounds, including the Virginia Military Reserve, Donation Tract, French Grant, and the three Moravian grants (Gnadenhutten, Schoenbrunn, and Salem).


Clark’s Grant, a 150,000-acre (61,000 ha) area in southern Indiana, is not divided into townships but is still subject to a gridded survey. Similarly, Portions of the Texas State Survey use square township survey. 

Moreover, Sizeable portions of Alaska, Arizona, California, Idaho, Montana, Oregon, and Washington, are unsurvey. Substantial swampy areas in Florida and Louisiana are also unsurveyed.

Required for Township Survey

Both New York and Pennsylvania have metes-and-bounds surveys, but in the western parts of these states, the metes-and-bounds form square township survey many of which are also civil townships. 


Besides these, nearly every state has areas of metes-and-bounds that were never included in the grids (like along major rivers) or were removed from the grid, usually due to surveying mistakes.


Instruments Required for Conducting City Survey

The following instruments are required for conducting a city survey

  • Total station with stand
  • Leveling instrument with stand
  • Leveling staff
  • Metallic tape
  • Invar tape

Topographic Map

The entire area is divided into a number of sectors, each of which is enclosed by a polygon. The polygons are connected by common sides. They are treated as closed traverse and the traversing is done by total station.


The interior details are located by plane table or the transit-and tape-method. These details include houses, roads, lakes, parks, railway lines, stations, etc.

Fly leveling is undertaken to establish the RLs of important points and benchmarks. Contouring is done by plane table or tacheometer. The nature of the ground surface is indicated in relief (i.e. coloring, shading, hatching, etc.) on the map.

Finally, all the sectors are assembled in one map so that the township survey area or city area.

Preparation of Street Map

The street map is prepared using a large scale to show distinctly the network of streets, roads, lanes, parks, etc. Names of streets, roads, and parks should be mentioned. In this case, also the township area is divided into different sectors. 


The street map of each sector is prepared by a plane table. In such a map the location of interior details (i.e. lakes, houses, and other properties) need not be shown. 


Fly leveling is done along the streets and benchmarks are established at different points for future reference.

Preparations of Property Map

This map is also prepared using a large scale to show the boundaries of public and private properties, plot numbers, premises numbers, and so on. The property map is also prepared by plane table by dividing the total township area into different

Water Supply and Sanitary Map

They bury the network of the water supply distribution system and sewer lines underground. To aid in pinpointing specific locations from above. They depict the complete networks of the water supply and sanitary works using conventional lines on the street survey map.


They use specific symbols to mark all essential lines and points, including intake points, purification points, check valves, fire hydrants, manholes, lamp holes, inspection chambers, and more.


Electrification Map:-


Normally, they bury the network of cables for electrification in the township or city underground. Thus, the street survey map should depict the distribution methods using a unique color scheme or suitable symbols.


They should clearly mark the specific points of the supply line to facilitate easy location in case of a cable fault. The street survey should include the map of the supply system, regardless of the electrification method.

Preparations of Telephone Map:-

The network of telephone cables also lies under the ground. To simplify fault location, the street survey map represents the network system using specific color conventions or suitable symbols.

Coordination Work for Township Survey

Similarly, The development authority of the city or town is responsible for the construction of streets, roads, culverts, bridges, flyovers, bypasses, subways, parks, public places, etc. 


The municipality or corporation is responsible for implementing the sanitation and water supply system.


The state electricity board carries out the electrification program, while the telegraph department manages the telecommunication system.
