Common Methods Used to Describe Real Estate

o Rectangular Survey System – also called as

government survey or geodetic survey system. To better understand this concept, think of a checkerboard. It has an intersecting line that forms a grid of squares. The �rst set of intersecting lines are called principal meridian which run north and south and base lines which run east and west.

Common Methods Used to Describe Real Estate

o Plat survey method – sometimes called the

lot-block-tract method. This is used in areas where land is subdivided into phase, block and lot and usually recorded in an approved subdivision plan. Example: Lot 2, Block 4, Phase 2 of Filinvest East, Antipolo City.

Basic Pointers in Map Reading

o Cardinal direction (north, south, east, west) o Bearings and azimuth (technical description) o Scale say 1:200

o Reference points (Bureau of Lands Location

Monument -BLLM, Bureau of Lands Barrio Monuments - BLBM, Tie Point or point of beginning)

(12)

Terminologies

o Surveying – science of making measurements to

determine the relative position of points and lines on the surface of the earth

o Lot Plotting – drawing the exact shape (square,

rectangle, trapezoid) and measurement of a particular lot from the technical descriptions shown in the title. The boundaries and lot orientation on the north, east, west and south are also attained.

(13)

Terminologies

o Map – it is a �at representation of earth’s surface

in paper

o Tie point – point one of the lot

o Tie Line – imaginary line connecting the known

geographic position (say BLLM) to the corner (point 1) of the titled property

o Relocation Survey – survey intended to verify

the boundaries of the property. The purpose of this is to ascertain whether or not there are encroachments.

(14)

Terminologies

o Subdivision survey – a survey to determine the

boundaries of each lot in a subdivision project

o Topographic plan – plan showing various

elevations of the property

o Contour lines – lines in a topographic plan

which indicate the elevation of the land at various sections

o Subdivision – a tract of land, in general,

(15)

Terminologies

o Simple subdivision – a subdivision where no

street or open space is delineated

o Complex subdivision – a subdivision with street

and/or open spaces

o Square planning – a subdivision scheme for �at

terrain

o Contour planning – a subdivision scheme where

the resulting blocks are more or less rectangular in shape

o Chaplan – indention along corner lot to allow

(16)

Terminologies

o Cul-de-sac – a passageway with only one outlet.

(17)

Terminologies

o Key lot – a lot adjoining a corner lot and fronting an intersecting

street. A lot that has added value because of its strategic location, especially when it is needed for the highest and best use of contiguous property. A key lot is also a lot that adjoins the rear property line of a corner lot and fronts on a secondary street.

Kind of Surveys

o Original o Subdivision o Relocation/veri�cation o Cadastral o Topographic o Engineering/Construction

o Hydrography - refers to the mapping or charting

of water's topographic features. It involves measuring the depths, tides, and currents of a body of water and establishing the topography and morphology of seas, rivers, and lake beds

(21)

Kind of Surveys

o Photogrammetry - the practice of determining

the geometric properties of objects from photographic images. Photogrammetry is as old as modern photography and can be dated to the mid-nineteenth century.

o Mining - deals with the particular challenges

faced by surveying in underground mines and tunnels as well as the more familiar surface surveys associated with open-pit mining.

Materials Needed in Lot Plotting

o Sample of TCT -o Triangular Scale

-o Protractor –

(23)

Steps on location or lot veri

�

cation

o Compare lot plan, title and tax declaration

whether they are agreeable with each other like name or owner, bearings, boundaries, etc.

o If the lot is not within the subdivision, hire a

licensed geodetic engineer especially if the property is rawland.

o Further veri�cation is done by asking the help of

the assessor thru its tax mapping division

o If it is a subdivision lot, refer to the subdivision

developer, homeowners association, owners of adjacent lots as to the correctness of the plan as shown in the TCT

o Verify actual area vs area stated in the title.

PLOTTING

1. Determine the scale to be use, if 1:100, this means 1 meter = 100 meters, which is the same as 100 centimeters = 100 meters or 1 centimeter = 1 meter.

Since the measurement is 11 m. you’ll need about 11 cm of paper, quite OK but I suggest that for initial plotting, use a bigger scale.

Say 1:200 m. which means 1 m.=200 m., OR 100 cm = 200 m and 1 cm=2m

2. Select on the paper the location of point “1”. For our example, just select any point near the middle of the paper. The paper must be oriented, meaning the edges should be facing the N-E-W-S

(47)

3. Draw a vertical line passing through the selected point “1” and parallel to the left and right edge of your paper. This vertical line represents the North-South direction.

a.) To draw a vertical line passing through point “1” place your ruler at the lower edge of your paper. See to it that the lower edge of the paper and the outer edge of the ruler coincides with each other.

b.) Place the right triangle on the inner edge of the ruler and slide the triangle until its vertical side is passing

(48)

4. Place the center of the protractor on point “1” with its vertical line or the 90 degree mark coinciding with the vertical line earlier

drawn in #3. From the vertical line of the protractor, locate the bearing angle, in our example 20 deg. 06’

Note: N 20 deg. 06 ‘E means the bearing angle of 20 deg. 06’ will start from the top vertical line above the point and incline toward the right. The key to follow is

such that if the line to be drawn is line 3 – 4 whose bearing is S 20 der. 06’W the bearing angle will start from the bottom vertical line going to the left. These divisions of four major quadrants are called NE quadrant, NW quadrant, SE quadrant and SW quadrant.

(49)

5.After marking the given bearing angle of 20 deg 06’NE, draw a line for

point “1” passing through the mark of the bearing angle.

6. From point “1”, the distance on ground is 11.00 meters since our scale is 1:200 m or 1 cm =2m we need to layout 5.5 cm paper to represent the 11.00 meter on the ground. Measure 5.5 cm from “1” this is now point “2”.

7. On point 2, draw a vertical line passing point 2, again, parallel to the left and right edges of your paper similar to the procedure done in #3. 8. Repeat #4, only this time, bear in mind that you are now plotting line 2

– 3, whose bearing is S 69 deg 54’E. therefore the bearing angle should be measured from the vertical line at the lower of point “2” and going to the right. Note that the line is in the SE quadrant. If you are using a half circle protractor you have to invert your protractor.

(50)

9. Repeat procedure #5.

10. We are now plotting line 3-4, do the same procedure as in #3 and so forth until point 4 is located.

11. We are now have to draw line 4-1 that is already

located on paper and just needs to be connected by a line. However, for veri�cation or as a counter check, it is better to proceed again as in # 3.

(51)

12. From point “1” after the lot has�nally been plotted on the paper, draw the tie line.

The tie line is the line that connects point “1” of the lot to a certain �xed surveying monument in our example. BLBM # 1.

Bearing Distance

BLBM # 1 to pt. “1” S 43 deg. 03’E 1,334.43 m. Pt. “1” to BLBM #1 N 43 deg. 03’W 1,334.43 m.

Note that we are plotting BLBM 1 to line 1 in reverse, because we are beginning at point 1 going to BLBM #1, instead of beginning from BLBM # 1 to point “1” should be done in actual relocation survey, since we are in reverse direction, the bearing of point “1” to BLBM #1 should also be reversed. That is the bearing of point “1” to BLBM #1 is N 43 deg. 03’W.

(52)

13. After plotting the lines, you now have to indicate the bearing and distance for each line on the paper.

14. To complete your plotting work, indicate the description of the adjoining properties and other needed date.
