The SURPAC “Lite” Module

The SURPAC “Lite” Module provides a Stand Alone, Entry Level suite of Survey Software applications, that covers the fundamental calculation and CAD requirements for most Survey Offices.

The omission of specific applications found in the SURPAC Conversions, Least Squares, Topographical, Engineering, Mining and Cadastral Modules makes the SURPAC “Lite” Module a cost effective “starter” suite of Survey applications.

In spite of these cost reducing omissions, the SURPAC “Lite” Module is able to provide a suite of Survey calculation solutions, as described below. Click the Button below in order to view a detailed description of the applications included in the SURPAC “Lite” Module. 

Purchasers of the SURPAC “Lite” Module may expand their SURPAC Software at any time, by adding on any of the other seven Modules. This may be done simultaneously, or at a future date.

The SURPAC “Lite” Module is currently priced at R 7 100.00 in Southern Africa, and at US$ 550.00 for countries outside this region.

The SURPAC “Lite” Module includes the following applications :
