SurGe
gridding and mapping software

Introduction
SurGe is a computer program which enables to generate a surface as an interpolation (approximation) function of two independent variables. The program has the following basic features:

Implements the interpolation / approximation method ABOS.
Basic input is a simple ASCII file containing X, Y and Z coordinates of points irregularly spaced in some region.
The surface can be defined not only by points, but also by spatial (three-dimensional) polylines.
So called fault lines can define discontinuity in the generated surface.
The generated surface can pass through points exactly or can be approximative.
Smoothness of resulting surface can be controlled by one parameter.
Large data sets (with noise) can be effectively filtered.
Quality of resulting surface is comparable with a surface created by the Kriging or Minimum curvature method.
Command line utilities support import of DEM, GRASS, ArcGIS and Shapefile data formats.

Installation

Windows
SurGe was compiled under MS Windows XP and it was also tested under MS Windows 2000 and MS Windows 98. It should run under other MS Windows operating systems without problems. The system must have at least 64MB of RAM and 2.6MB of free disk space for installed files.

To install the program, follow these steps:

Download SurGe630.exe.
Run SurGe630.exe and perform standard installation steps.

The installation creates shortcut (link) icon to the SurGe Project Manager (SPM.EXE) at your desktop.

It is also recommended to edit your AUTOEXEC.BAT and add the full name of the SurGe directory (for example C:\SURGE) into the environment variable PATH. If your operating system does not use AUTOEXEC.BAT (for example Windows XP), modify PATH in the system dialog "Environment variables".

Linux
Linux users may try to download SurGeLin.zip and test the SURGEF interpolation engine (see SurGe User's Manual) as a stand-alone console application (graphical user interface SurGe is not available for Linux).

If you are a new user of SurGe, it is strongly recommended to go through the SurGe Tutorial, where the usage of SurGe is explained step by step.

Registration

This version of SurGe is a fully functional unregistered version - the string "Unregistered version of SurGe" is displayed in the upper left corner of every screen. Also SPM and FMEW have certain limitations in the unregistered version. If you want a registered version and to support future development of SurGe, send $20 (US dollars) and your e-mail address to me by ordinary mail (please, do not send a cheque). Then you will obtain a registered version of SurGe by e-mail. Registered users will obtain new versions of SurGe automatically.

If you have any problems or suggestions, contact me via e-mail.
