Mathematical Digital Terrain Model (DTM) Data for Testing DTM Generation Methodologies and Software	2021	14	.pdf	application/pdf	4826	197	60	Actual DTM data points invariably have errors which affect the course of the computations and analysis and thereby make it difficult to evaluate which effects are due to the method used for the determination of X, Y, Z ground coordinates of DTM data points, which due to the geometry of the problem, and which due to shortcomings in developed software. Measured, or actual, DTM data points may not be available or invariably have errors which affect the course of the computations and analysis.	cache/american_scientific_journal-6640.pdf	txt/american_scientific_journal-6640.txt
