Mapmost

City-scale 3DGS Full-stack Solution

The solution covers the full pipeline from intelligent route planning → automated multi-GPU cluster modeling → high-performance web rendering and application development.

It supports 3D reconstruction of up to 100 km², with modeling efficiency as high as 1 hour/km². It also fuses and renders 3DGS models with traditional oblique photography models and vector base maps, and provides diverse application capabilities such as POI object management and spatial measurement — delivering a standardized 3D foundation for digital twins, smart cities and emergency disaster assessment.

3DGS VS Oblique Photography

Real-time visualization preview, efficient and intuitive, with minute-level rapid modeling

Efficiency

No real-time feedback on modeling progress; time-consuming, same scene takes hours to model

Visual quality close to real photos, high-frequency details fully preserved — fine structures like building ornaments and vegetation restored at >90%

Detail Preservation

Insufficient visual detail — fine structures like building ornaments and vegetation retained at <50%, with cracks and blur, weaker realism

Compact data size saves storage and transmission; only 10% of oblique models for the same scene

Storage & Transmission

Large data size hampers efficient transmission and cloud deployment; 10× the data of 3DGS for the same scene

Supports multi-temporal scene simulation, rendering monthly or yearly real-scene changes in continuous animation

Dynamic Scenes

Hard to show multi-temporal scene changes; layer-switches between models from different times
