I am happy to provide what support I can. However, I am no longer an active user of any Microsoft Operating system. (I have been using Linux almost exclusively for many years now).  I have no plans to produce a new release of QuikGrid.


GENERAL DESCRIPTION

QUIKGRID is a program which will read in a set of scattered data points (x, y, z) which represents a surface. The program will generate a grid from this data and then display the surface as a contour map, or as a 3d representation. The left mouse button may be used to zoom in and pan about the display. The right mouse button may be used to display information about the generated grid coordinates and data points.

A 200 by 200 grid representing 235,000 data points may be gridded in less than 3 seconds on a Intel Atom powered computer (actual generation times may vary depending on how the points are distributed). The grid may be displayed as a wire frame or as a hidden surface grid, optionally with colours. The grid and contour lines may be output as a DXF file. The generated grid may be output to a file as a series of XYZ triplets, in the DXF 3DFACE format or as an ER Mapper Raster Dataset. QuikGrid may be used to view 1-degree USGS DEM files.

QUIKGRID is easy to use. It will run on modest hardware platforms. It is well suited in situations where it is desired to have a quick look at a set of data points, for example under field conditions where only a portable PC is available. QuikGrid is documented through its help facility.
