Expanding the possibilities of Geomatics and Survey Sciences.


Introducing PECA’s Survey Management System (SMS) software, a revised version of the successful Level Monitoring System (LMS).  SMS inherits the same interface and ease of use as the LMS with additional capabilities to support 3-D traverse network, triangulation network, and intersection network.  SMS is a suite of integrated system designed to cater for the needs of the surveyors and engineers in all aspects of leveling, traversing and tachometry. With options for GPS input, it is a model for day to day field and office activities that include data collection, processing, computing and management. SMS modules are comprehensive and offered to the user in a friendly and multi-tasking envi­ronment. It equips the user with tools and means to faster job execu­tion, and reduced costs by cutting down the duration of projects to essentially the period of field activity.

Our surveying software turns the once complex task of network levelling and adjustment, comparison of data sets and trends analysis into a straightforward operation that can be easily and rapidly performed at the site on a laptop computer or at the office on a desktop computer.

History of SMS

SMS was developed as a bid to meet versatile and very demanding requirements in the surveying and construction industry. Under the theme “Design and Implementation of a Level Monitoring System”, the software was the basis of a successful presentation to the Royal Institution of Chartered Surveyors in 1995, for test of professional competence.

Level Monitoring System (LMS DOS), as it was known, was evaluated and rigorously tested against on-going projects, such as Channel Tunnel Rail Link, at Engineering Surveys Limited (UK). Even at that early stage and as a DOS based solution, the software performed satisfactorily in handling large projects, including level monitoring project undertaken at Channel Terminal at Cheriton. Similarly, subsequent evaluations were carried out by Rail Link Engineering (UK) who certified the product’s simplicity of use and functionality as excellent.

LMS DOS evolved into Level Management System (LMS Windows) and running under Microsoft Windows. In 1995 Leica UK adopted LMS Windows to support the sale and use of Digital Levels. A comprehensive five-page report by Leica is available here. Through this marketing arrangement with Leica, many organizations purchased and adopted the use of LMS Windows.

The success of LMS Windows spurred further developments to broaden applications; such that at present the surveying software provides comprehensive tools and functions to support all requirements in levelling. LMS Windows transformed into Survey Management System to provide the same level of functionality in the use of digital levels, total stations and GPS with additional capabilities to support 3-D traverse network, triangulation network, and intersection network. Hence, the integrated system which is the hallmark of our surveying software today.

SMS is customer driven. The Dredge facility was written to meet the requirements of our contract with the Shell Petroleum Development Company, while Geodetic Transformations were developed at the instance of a government agency’s survey requirements. Similarly, Land Records System is evolving into a Land Information System to meet requirements of survey departments and surveyors in private practice.

We have the trust and confidence of our customers. We sustain this relationship by employing the best in technology, extensive research, listening to customers and creating solutions in surveyor’s familiar interface.

The SMS suite of surveying software is designed in modules to allow you, our customers, to start out with a combination that suits your current workload and resources; giving you the potential to add modules as your requirements change. With this arrangement, users can progressively acquire the whole suit and gain the full benefits of increased productivity, profitability and competitive advantage.
