چکیده

The latest series of topographic base map Nepal were prepared by Survey Department during 1992-2001 A.D and preparation their digital database namely National Topographic Database started in 1999 A.D. Understanding the utmost need updating these maps database, department update process a rapid pace from fiscal year 2075/76 B.S based on ZiYuan-3 Mapping (ZY-3) satellite images with 2.1 m panchromatic 5.8 multispectral spatial resolution. overall procedure includes image processing, feature update, field verification, data compilation, finalization, approval Technical Subcommittee finally reproduction. technical aspects this whole is standard specification document “Specifications for 1:25000 1:50000 Base Maps”. First level verification all grid sheets covering was completed 2078/79 now phase At end 2079 B.S, around 250 number have been approved are made available department. With completion series, there further opportunities to produce thematic data/maps as well administrative smaller scales. Furthermore, availability higher resolution through LiDAR, UAV other resources, has work large scale mapping coming days.

Relational Generative Topographic Map

The generative topographic mapping (GTM) has been proposed as a statistical model to represent high dimensional data by means of a sparse lattice of points in latent space, such that visualization, compression, and data inspection become possible. Original GTM is restricted to Euclidean data points in a vector space. Often, data are not explicitly embedded in a Euclidean vector space, rather pa...
