Activities Required in the Preparation for Remote Sensing Control Measurement Work

17:41, 11/07/2024

The Ministry of Natural Resources and Environment has just issued Circular 08/2017/TT-BTNMT regulating the process for remote sensing image control measurements.

The preparatory work for remote sensing image control measurement is stipulated in Circular 08 as follows:

1. Determine the area for remote sensing image control measurement.

2. Collect documents including:

- Remote sensing images of the control measurement area;- Diagrams, coordinates, and elevations of national coordinate and elevation points within the remote sensing image control measurement area;- Technical designs and other related technical documents;- The latest topographic maps of the remote sensing image control measurement area.

3. Determine the method for remote sensing image control measurement, including: measurement using static GNSS technology or using transit methods with electronic total stations or electronic theodolites, depending on the technical design.

4. Inspect the equipment used for remote sensing image control measurement:

- GNSS signal receivers used in remote sensing image control measurement must have valid inspection certificates;- Electronic total stations, electronic theodolites, invar measuring tapes, and steel tapes must have valid inspection certificates;- The equipment must be inspected before conducting the remote sensing image control measurement. Inspection documents must be attached with the remote sensing image control measurement results.

More details can be found in Circular 08/2017/TT-BTNMT, effective from July 24, 2017.
