3D MODEL OF YANGON (MYANMAR)
3D GEODATA OF YANGON
3D City model of Yangon covers 503 km2. The project was completed for 2 local telecom operators considering their specific RF planning requirements.
We use recent vintage stereo imagery 0.3 m resolution to create 2 m high-resolution geodata in LOD2 quality. 3D geodata accuracy – 2-3 m in x,y,z.
Digital Surface Model (DSM), Digital Terrain Model (DTM) and Digital Elevation Model (DHM) were produced based on 3D terrain features which were derived from overlapping satellite imagery is taken from two different locations (stereo imagery).
Highly accurate building vectors with associated height values as attributes are captured through three-dimensional feature extraction in our photogrammetric software.
Clutter/Land Use/Land Cover describe the surface and built-up features which influence on radio wave propagation. They are classified into different classes: classes of built-up areas, water classes, classes of landscape and vegetation. Urban Land Use map is produced from multispectral satellite imagery by the method of automatic classification with subsequent manual photo-interpretation and modification.
Usually, outside the areas of 3D city coverage, operators still require geodata for RF planning and optimization in suburbs. We propose 2D Urban Model, 2.5D Urban Models, 2D Regional Models with clutter height with 5, 10, 20 m resolution, with DTM, clutter (land use) and vector layers. Our geodata catalogue includes over 4000 cities and 60+ countries.
