What is ThaiSurf ?

In short, ThaiSurf is a computer program that helps users to create surface models and conpute spot heights for any part of Thailand and its neighborhood. Its users can do it all on their desktop without using paper maps that they might never have access to.

ThaiSurf can compute spot heights at any place, on lands and under seas within the extents that cover the whole kingdom and its vicinity. Moreover, ThaiSurf can generate contours and birdseye views of topographic terrain in several extents of users’ choice. In the optional measurement mode, users can click at any place on the display of contour to measure terrain height and draw line to generate a corresponding profile curve. Lines of sight and surface lines may be drawn between any two locations of users' choice. Labels for spot heights, index contour elevations, or users-defined texts may be added on the contour model and displayed on all types of terrain models supported by ThaiSurf.

The coordinates (latitude & longitude) of points where spot heights or terrain models are needed can be entered in degrees or degree-minute-second or by selecting from the lists of location names in the provided POI files which can be modified and expanded. An image map of Thailand on the main dialog box can be used by point-and-click to define locations where spot heights are computed for or terrain models are generated on the screen, printer or files.

ThaiSurf uses digital elevation data from GTOPO30, GLOBE and Terrainbase as its main sources of input data. Other minor data are:- location names, coast lines, state boundary, and provincial boundary lines which may be used to draw or drape on the terrain models as needed.

ThaiSurf was created to serve the need of scientists, geographers, and engineers in solving problems that involves the use of terrain models of the areas within and around the kingdom of Thailand.
