BASIS POINT MEASUREMENT AND MAPPING TECHNIQUE (Part II)

31 Desember 2010 - Surveyor Kadastral

Planning

In this installation technique is the basic point for refinement, planning placement basis point location technique performed with the grid system, with length and width of the grid is adjusted to the density as defined in article 2. Density referred to is the maximum density permitted and placement planning cultivated as much as possible close to the location of which can be reached (eg roadside, residential) to facilitate mobilization and measures to be undertaken.

Plan installation of base point on the map planning techniques available are also included technical base point number that will be installed. Numbering basic point technique done by referring to Article 6 and Annex 2.
Example:

09 002 - point second-order technical basis situated in the Province of DKI Jakarta with sequence number 2.
0901002 - technical base point order 3 is located in the Province of DKI Jakarta, Central Jakarta Municipality with sequence number 2.
2 points 4th order technical base in a region of villages with sequence number 2 with the national coordinate system.
3 point 4th order technical base in a region of villages with sequence number 3 with the local coordinate system.
- Point base refinement technique is temporary and serves as a point of help during the measurement of land took place. To facilitate the marking point of the basic techniques of data refinement in the form of measurement and calculation, measurement officers are given the freedom to provide with a record number must be unique / singular at every base point refinement technique for doing measurement of land.

Code of provincial administration and district / municipality in accordance with schedule 6 is the name of the provincial and district / Municipality of record at the time of this pearaturan determined. For new administrative regions that emerged after the enactment of this legislation, administrative code is made by continuing administration of the code contained in these regulations, in the order in which the relevant stipulation of local administration, for example, for the Municipality of Bekasi a predetermined after the publication of this rule will get a code 26 for the Regional Level II. For the purposes of coordination of the code of Provinces, the Directorate of Measurement and Mapping will establish codes of Provinces and the National Land Agency Regional Office at the provincial level will establish Regional Level II codes in case of addition of new administrative regions.

Numbering technical base point which will be installed conducted with respect to the serial number of basis points last technique in accordance with ordenya in the province / regency / municipality concerned (based on the results of the inventory amount of technical base points that have been installed). Example: the serial number of technical base point order 3 at the Central Jakarta District last one is 30, then the serial number of the basic point that the new technique will start at number 31 and so on.

In this installation technique is the basic point for the binding of parcels of land and parcels of land that does not have a base map sheet registration / map registration, at a location that will be installed technical base point marked on the planning map that had been prepared with the following criteria:

• When these parcels of land including agricultural areas, the applicant should prepare a measurement of at least 2 (two) basis point 4th order technique with maximum installation distance of 1.5 km (according to map sheet format 1:2.500 scale registration to be made).

• When these parcels of land including residential areas, measuring the applicant must prepare at least 2 (two) basis point 4th order technique with maximum installation distance of 500 m (in accordance with the format sheet map 1:1.000 scale registration to be made).

• When these parcels of land including a large plantation, measuring the applicant must prepare at least 2 (two) basis point 4th order technique with maximum installation distance of 6 km (according to the format map sheets 1:10,000 scale registration to be made).

• When pieces of land located at a distance measured more than 2 (two) miles of 2 (two) or national technical base points is a maximum 2 (two) miles to 1 (one) national technical base points, mapping the basic point that techniques will be used as binding should be done on planning maps.

Preliminary Survey

Preliminary survey is the phase of activity aimed at ensuring the basic point mounting location in accordance with the planning techniques that have been done by looking at actual conditions in the field. At this stage every point of which will be installed in the field and the point to be used as a bonding point must be reviewed his physical condition in the field. If the location that will be installed including areas within the administrative boundaries provincial / regency / municipality / district / village, where possible planning the installation of the basic point technique performed on the administrative boundary with respect to the administrative map of the area. If the point of basic techniques that will be installed is the basic point 4th order techniques, monuments of other agencies in the vicinity of the location should be checked for physical condition. This is done as a basis to determine whether the monument that other agencies can serve as the technical base point of order 4 or not.

For each of the points that will be installed (new points), if the measurement using satellite observation methods, must meet the following criteria;

1. The location was convenient.
2. Space-free view of the sky from horizon  15 .
3. Away from sources of electrical interference.
   

The points are fitted and measured with terrestrial measurements must meet the following criteria;

1. Each point on the network framework technical base point should be seen by a point before and after.
2. Angle to be measured should not be too taper (angle of not less than 30 and not too obtuse (angle not more than 330.
3. Are not on the ground with a steep slope and not swampy.
   

Remember basic point function techniques as fastening, Sought technical base point location should be on state land and soil conditions are relatively stable. Example; located in the offices of government / private sector. After considering all the above criteria, mark the location of the basic point of these techniques with wooden stakes in the field and on the map plan and attempted to obtain permission from the head of the installation of a local agency if the basic point is a technique that will be installed in government offices and private land owners if basic point of these techniques will be installed on public lands. Similarly to the agency owner of the monument when the monument that agency will be used as a base point 4th order technique. When the monument is used, specify the number of these techniques the basic point on the map plan in accordance with attachment 1. Numbering is as follows: if the court found the City Planning Department with monument monument number DTK-205, on the maps included plans DTK-205/101, where 101 is the serial number of technical base point 4th order in the village is.
