The density of the points is set according to the instructions of the network being created. During
the design process, it is necessary to ensure that the points are evenly distributed across the
object.
The following requirements must be observed when determining the installation location of the
projected point:
1. Ensuring that measurements are performed under normal conditions.
2. Ensure that there are no strong radio waves propagating sources around the point (1-2 km).
3. There should be no obstruction in most parts of the horizon around the point and the horizon
of the barrier should not exceed 15 .
4. Ensure that the point stays on for a long time.
5. Use the point at any time of the day and provide access.
When designing the measurement work, it is necessary to repeat at least 50% or 25% of the total
number of identified vectors. Repeated measurements should be determined on a different day
and at a different time (observation window). In addition to project control, the design of the
measurement of the vectors of the base points also increases the reliability of the design. When
determining the length of long vectors (20 km), meteorological parameters (temperature,
pressure, humidity) are measured and recorded in the log.
If the points in the state geodetic network are 5 km away from the projected object, it should be
included in the project network.
The graphic part of the project shows the base points and the points to be identified on the maps,
i.e. the project network is shown in full.
An explanatory letter in the final part of the technical project, ie the following information
should be fully presented.
1) the basis of the technical project, normative documents, the study of the geodetic network, the
study of the physical and geographical characteristics of the object, the design work and the
definition of the coordinate system.
2) The set of previous works, the name of the geodetic base points, the type of work, the year in
which the organization performed the work, the accuracy assessment report and the coordinate
system.
3) Scheme of work performed Methods of measurement work.
4) Technology, procedure and conditions of delivery of finished works.
5) Cost estimates of the designed works.
