Lesson 2.3 Survey plan preparation, standards and specifications for control, cadastral, and isolated surveys Lesson Summary A survey plan maps a parcel of land created by precisely examining and measuring the property. It determines and delineates boundary locations, shows physical features and other items of spatial importance. Furthermore, it is considered a legal document once registered and approved by a governing agency. In the Philippines, the Department of Environment and Natural Resources (DENR) has jurisdiction to approve such plans. Hence, DENR issued the Memorandum Circular No 2010-13 on adopting the manual on land survey procedures wherein the standards and specifications for plans are indicated. This lesson will discuss the standards and specifications for geodetic/project control, cadastral, and isolated maps.

Learning Outcomes At the end of the lesson, the student should be able to: 1. Enumerate the standards and specifications in making geodetic/project control, isolated, and cadastral plan

Discussion Definition of terms 1. Control Survey – survey conducted to determine the horizontal and vertical positions of points which will form part of a geodetic network or project controls over an area which will subsequently become the basis in determining the rectangular coordinates in an area (Section 4 of DAO 2007-29). Control survey can be classified as Geodetic or Project. a. Geodetic Control Survey - surveys conducted covering extensive areas which take into account the curvature and the geoid-spheroidal shape of the earth at sea level for the purpose of establishing basic network of reference points, covering the first and second order controls (Section 4.a of DAO 2007-29). b. Project Control Survey - surveys conducted to establish the positions of points of reference for projects with a limited geographic coverage such as a municipality, a large isolated tract of land, a group settlement, a barangay or group of Page 1 of 21 Vision: Mission:

municipalities, covering primary control (third order), secondary control (fourth order) and tertiary control (Section 4.b of DAO 2007-29). 2. Cadastral Surveys – survey made to determine the metes and bounds of all parcels within an entire municipality or city for land registration purposes (Section 5 of DAO 2007-29). a. Numerical Cadastre – cadastral survey wherein bearings and distances of the individual lots are determined from the computations based on the actual ground survey b. Graphical Cadastre – cadastral survey wherein bearings and distances of the individual lots are determined using transit and stadia, scaling from photo map, and other graphical methods c. Public land subdivision – subdivision of Alienable and Disposable (A&D) lands covering an area of more than 1,500 hectares 3. Isolated surveys – comprised of all classes of surveys of isolated parcels of land used for agricultural, residential, commercial, resettlement, or other purposes covering areas not more than 1,500 hectares (Section 6 of DAO 2007-29). a. Group Settlement/Townsite Subdivision Surveys – subdivision of A&D lands of not more than 1,500 hectares into 50 parcels or more b. Public land surveys – all original surveys covering A&D lands which has not subjected to private rights nor devoted to public use pursuant to the provisions of public land laws c. Amendment surveys – surveys covering untitled/undecreed properties by changing the number of lots without affecting the original technical description of the boundary d. Private land surveys – surveys covering lands claimed or owned by an individual, a partnership, a corporation, or any other form of organization, undertaken for purposes of original or subsequent land registration e. Government land surveys – surveys of parcel of lands administered by or belonging to the National Government of any of its branches and instrumentalities which include: i. Friar land estate surveys – surveys on lands purchased by the government from the Religious Orders and private corporations from 1904 to 1913 ii. National government lands surveys – surveys of all patrimonial properties owned by the government not intended for public use Page 2 of 21 Vision: Mission:

Conversion surveys – surveys conducted for the purpose of transforming/converting the lots covered by approved graphical cadastral surveys, cadastral mapping (Cadm) and photocadastral mapping (PCadm), into numerical or regular cadastral lots, with computation and plotting in the system of the cadastral project.

g. Other land surveys – surveys made for purposes of determining the metes and bounds of parcels not included in the enumeration above and intended for a specific purpose Each of these surveys requires the preparation and approval of plans from DENR to register such property formally. The following specifications and standards focus only on the information found in the survey plan. However, other requirements need to comply with the approval of such plan. Other requirements are listed in the DMC 2010-13.
