Nowadays the profession of Land Surveying has changed name to Geometrics. ‘Geomantic is the science and study of spatially related information and is particularly concerned with the collection, manipulation and presentation of the natural, social and economic geography of the natural and built environments.’ (Royal Institution of Chartered Surveyors (RICS). So Land Surveyors are now Geometricians.

- General of Topographic Survey
We provide all types of topographic survey at scales from 1:50 through to 1:2500 using the latest robotic and reflector less total stations, GPS Station. These services are provided to Architects, Consulting Engineers, Property Developers, Utility Companies and Government departments.
Topographic surveying involves the production of maps and plans which are true to scale. Topographic maps are produced to accurately represent details of both the natural and built environment. They will also include symbols representing features or data too small to produce to scale.
Height information is added in most cases as spot heights and feature elevations; this height information is related to a control datum such as Ordnance
Datum or a fixed local datum. Height information is also used to generate contours to provide a better visual representation of the changes in terrain height across the site.
Our Survey team regularly carries out high standard site surveys for our clients. Topographical and Site Surveys are directed towards planning and design for Architectural and Engineering Precise control networks are established using GPS or Total station survey techniques. All survey data is digitally captured using LEICA instrumentation
Survey drawings are output via a range of hard and soft media and in any file format required to meet our client’s needs.
- Pipeline Survey
Our experience with pipelines ranges from pre-design topographical surveys and route mapping, through construction stake out and as-built survey, to the maintenance stage with pipeline mapping of anomalies. Our experience includes oil, gas, water and sewage pipelines.
- Airport Survey
We have surveyed numerous airports and airfields, both military and commercial including runways, taxi- ways, terminal buildings, navigation aids and obstacle surveys. WGS84 control to CAA standards
- Measured Building Survey
Dimensional building surveys for floor plans (re-furnish, re-design or to compute settable floor space), cross sections roof plans and elevations.
- Surveillance Management
GSMTL has performed and managed various projects in different provinces with professional surveying crews who are experienced and qualified staff being highly trained outside and graduated from Universities and can deal with various surveillance tasks in accordance to project management tasks with up-to-date equipment like Total Station and Station GPS within consideration to projects assumed standard and requirement.
- Surveillance Services
A Topographic map (‘Topo’) is a site map showing the topographic features of a site by way of contour lines. Topographic features could include drainage patterns, locations of rock outcroppings, hills and other natural features. The map may also include artificial features such as buildings, utility locations, detention ponds and other features which would affect engineering design on the site. Topographic contours can be shown at almost any interval that is specified by the client. In areas of steep terrain, a larger contour interval can show the topography without the crowding of contour lines that would be introduced by a smaller contour interval. In areas of relatively flat terrain, a smaller contour interval is necessary to show the small changes in topography in a meaningful way. The topographic map is prepared by gathering horizontal and vertical information in the form of XYZ coordinates. For smaller sites, the information may be gathered by traditional survey methods using a Total Station and data collector. For larger sites, it may be more cost- effective and produce better results to use aerial mapping methods. After the raw data has been gathered, it may be used to create a digital terrain model as an intermediate step to the production of contour lines.
- Terrain Modeling
GSMTL Company has professional engineers to provide Digital Terrain Modeling which is the electronic process of representing topography in three dimensions. Which requires converting gathered raw data (XYZ) into the data which is more suitable for the mentioned purpose. An example of this would be in the preparation of a topographic map. The surveyor will gather data at particular spots chosen to accurately represent the field conditions.
However, the finished product will need to represent information at places where raw field data is not actually gathered. By the process of digital terrain modeling, the information actually gathered can be converted to the information represented without loss of data integrity.
