About
E-TEK apply scientific and engineering principles to evaluate possible environmental impacts and develop mitigation measures and successful solutions.
As part of our Topographic Survey service offering, we provide assistance in the following fields:
Data Analysis and Visualisation
Data Management
Data Acquisition and Integration.
Data Analysis and Visualisation
Spatial analysis involves comparing the characteristics and the relationship between places and lends new perspectives to decision-making. Our team employs elevation data in conjunction with other geospatial information for visualisation, interpretation, modelling, and to support decision making. The analysis of topographic features include slope, aspect, viewshed, elevation, contour lines, flow, and flow lines, which enable us to carry out:
Water resource and water management studies
Contaminated land mapping
Land capability assessments
Visual impact assessments
Sensitivity analyses
Material cut and fill balances
Erosion studies
Social impact assessments
Data Management
Aerial photography, satellite imagery, data acquisition and transformation are some of the most powerful data-capturing techniques for the creation of GIS spatial databases. Our services include checking, mosaicking, georeferencing, and georectification of raster datasets for use in mapping.
Accurate data on land use and land cover change are crucial for liability forecasts, monitoring, and other environmental and remediation studies.
We identify, measure, and describe change in geospatial data, its features, and attributes captured with mapping software and imagery
Data Acquisition and Integration
The acquisition of quality data is one of the key variables in obtaining meaningful results. Our team gathers and verifies quality geospatial data through accurate desktop studies of imagery, maps, drawings, photogrammetry, and reports. We also execute detailed field data collection with GPS mobile capturing devices and survey equipment.
