GIS AND DRAFTING

SITE PLANS

Our site plans combine real-world geospatial data with detailed spatial representations of specific project areas. These plans are essential for planning, development, construction, and environmental assessment.

We integrate multiple datasets including aerial imagery, cadastral boundaries, LiDAR contours, and GIS shapefiles such as watercourses, utility networks, rail corridors, and sample locations. Site plans are georeferenced and may include overlays of construction drawings, mine workings, or historical imagery to identify potential conflict zones and establish buffer areas.

HISTORICAL AND AERIAL MAPPING

Using GIS to visualise change over time is a powerful tool for understanding shifts in land use, landscape features, and human impact. These maps are commonly used in heritage assessments, urban development, ecological restoration, and long-term environmental monitoring.

At RCA, we produce comparative aerial mapping series that track the evolution of a specific site and its surroundings — providing valuable insights to inform planning, investigation, and management decisions.

STRUCTURAL SECTION DRAWINGS

A structural section drawing provides a vertical cross-section view through a site or structure, revealing internal layouts and construction details not visible in plan view.

At RCA, we specialise in producing geotechnical section drawings that illustrate subsurface profiles based on data from boreholes, test pits, or cone penetration tests (CPTs). These sections help visualise soil and rock layers, groundwater levels, and geotechnical features critical to design and construction planning.
