What can you do in Nuwa with Vector Maps?
Vector data is the most common type of geographic data. Compared with raster data, which uses cell matrix to represent geographic data, vector data has better accuracy and display quality, which means no loss of accuracy and graphic distortion when scaling the vector maps. Generally, points, lines and polygons are used as vector data to represent geographic data. DXF, DWG, KML, KMZ, SHP, LandXML, etc, are commonly used vector data formats in the field of GIS.

Definition and Uses of TIN Surface
Triangular Irregular Network (TIN) surface, as the name explains, is a type of vector-based surface network data consisting of a series of irregular triangles. Digital Elevation Model (DEM) is more commonly referred to in the surveying field, to define regional elevation topographic data for data exchange between different software. And TIN is a typical type of DEM. In addition to this, DEM has various forms such as raster map, contour lines, and regular grid, etc.
