Khảo sát khu xây dựng theo ô lưới giữa sa mạc

Create one continuous 12-second drone video, aspect ratio 16:9, presenting a large residential construction site on flat arid terrain. The mood is orderly, technical, and quietly ambitious. Show a clear progression from serviced plots to slab foundations, blockwork houses, and finished roof structures. Every worker wears a hard hat, high-visibility vest, safety boots, gloves, and suitable eye protection. Maintain a safe survey altitude throughout.

[00-04s] Move laterally in a straight line with the camera pointed vertically downward and a distortion-controlled 35mm-equivalent lens feel. Workers inspect foundation edges from designated walkways. Crisp morning sunlight produces consistent shadows that clarify the plot geometry.

[04-08s] Continue the lateral survey at constant speed and altitude, keeping the same overhead lens perspective. A water truck advances along a separate haul lane, leaving a subtly darkened strip of damp soil. Bright natural light reveals tire impressions and compacted earth without excessive airborne dust.

[08-12s] Maintain the straight flight while gradually tilting to a shallow oblique view, retaining the 35mm lens feel. Repeating residential rows extend toward the horizon as workers continue ground-level inspections. Morning illumination remains stable.

Sound design: dry breeze, distant truck engine, low machinery rumble, and faint rotor noise.
