Hanoi-Vietnam: Technological labor norm in the preparation of road plans of remote sensing images

Technological labor norm in the preparation of road plans of remote sensing images in Vietnam (Illustrative photo)

The economic-technical norms issued together with Circular 08/2019/TT-BTNMT define the technological labor norm in the preparation of road plans of remote sensing images at scales of 1:5,000, 1:10,000, 1:500,000, and 1:1,000,000 in Vietnam. To be specific:

1. Task Content:

- Collect and take remote sensing images

- Measure photo control (applied only for thematic maps at scales of 1:5,000 and 1:10,000), as per the Circular promulgating the economic-technical norms for remote sensing photo control.

- Establish a digital elevation model (applied only for thematic maps at a scale of 1:5,000).

- Input initial data.

- Densify remote sensing image blocks.

- Geometrically correct remote sensing images.

- Enhance image quality.- Align, merge, and cut remote sensing image tiles.- Frame setup, coordinate grid, annotation, and outside frame elements of road plan of remote sensing images.

2. Difficulty classification:

- Type 1: Plains region, sparsely populated, simple structures; Low mountain regions, sparse vegetation and population, non-disrupted terrain; Easy judgment and point determination.

- Type 2: Plains region with relatively dense population, small commune-level towns, and industrial zones; Intermixed hill and mountain regions, relatively dense vegetation; Difficult judgment and point determination.

- Type 3: Densely populated plains region; Cities, district-level towns, large industrial zones, complex structures; Mountainous, high mountains, dense vegetation; very difficult judgment and point determination.

3. Staffing: 01 measuring cartographer III.4

4. Norms: Work/fragment

Details can be found in Circular 08/2019/TT-BTNMT effective from August 20, 2019.
