Rethinking Amortized Neural Representations for High-Resolution Terrain Elevation Data
Rethinking Amortized Neural Representations for High-Resolution Terrain Elevation Data

A controlled benchmark of amortized neural representations on high-resolution (1 m/pixel) terrain elevation data, and HUVR+SIREN — a hypernetwork with a smooth, analytically differentiable decoder that attains the best height and derivative fidelity with no extra per-tile storage.

ImplicitTerrainV2: Wavelet-Guided Spatially Adaptive Neural Terrain Representation
ImplicitTerrainV2: Wavelet-Guided Spatially Adaptive Neural Terrain Representation

A wavelet-guided, spatially adaptive implicit neural representation for digital elevation models. A wavelet complexity field localizes high-frequency capacity to complex terrain, and post-training compression reaches 1.23 bpp — 66.25 dB PSNR on Swiss terrain tiles, +5.70 dB over prior work with 3.2x fewer parameters.

A Parallel Scale-Space Method for Critical Features Tracking on Triangulated Irregular Networks
A Parallel Scale-Space Method for Critical Features Tracking on Triangulated Irregular Networks

A scale-space pipeline for terrain represented as Triangulated Irregular Networks (TINs): scale-aware seam-free sampling, an improved TIN smoothing operator, and a fully parallel GPU algorithm for tracking critical points across scales without global sorting.

Critical Features Tracking on Triangulated Irregular Networks by a Scale-Space Method
Critical Features Tracking on Triangulated Irregular Networks by a Scale-Space Method

Best Paper Runner-Up at ACM SIGSPATIAL 2024. A scale-space method that identifies and tracks topologically important terrain features directly on Triangulated Irregular Networks, handling irregular point distributions and boundaries that grid-based DEM methods cannot.
