Technical note

Before you convert ASC to GLTF

ASC is made of pixels and GLTF is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a GLTF container.

FAQ

ASC to GLTF Conversion

What are ASC files?

The ASC (Esri ASCII Grid) format stores raster geospatial data as plain text. Developed by the Environmental Systems Research Institute (ESRI), it describes a rectangular grid of cells using a short header — number of columns and rows, coordinates of the lower-left corner, cell size and a no-data value — followed by the cell values themselves, written row by row as ordinary numbers. Because the entire grid is human-readable text, ASC is widely used for exchanging elevation models, slope maps and other continuous surfaces between GIS packages that would otherwise share no common binary format.

What are GLTF files?

glTF or GL Transmission Format is a vector extension developed by the non-profit consortium Khronos with the aim of improving interoperability between various types of software specialized in creating and accessing 3D content. The extension is compatible with several application programming interfaces (APIs) that offer 2D and 3D vector graphics rendering, including WebGL, OpenGL ES and OpenGL.
