FastPro-Gaussian: Accelerated True Digital Orthophoto Map Generation with Progressive Densification and Spherical-to-Ellipsoidal Gaussian Transformation

Compared to state-of-the-art methods, the proposed FastPro-Gaussian achieves comparable TDOM fidelity with over two-fold acceleration in training time (notably more than two times faster than Tortho-GS), confirming its strong potential for practical deployment in geospatial production pipelines.
