Geographic Information Systems Analyst

We are seeking a skilled GIS Analyst with expertise in drone-based photogrammetry, LiDAR point cloud processing, and classification using TerraSolid software. The candidate will be responsible for processing UAV imagery, classifying point clouds, generating accurate geospatial datasets, and producing high-quality mapping deliverables for surveying, engineering, infrastructure, and topographic mapping projects.

Key Responsibilities

• Process and analyze drone imagery using photogrammetry software to generate orthomosaics, Digital Surface Models (DSM), Digital Terrain Models (DTM), and 3D models.
• Perform LiDAR point cloud processing, classification, and quality control using TerraSolid software, including TerraScan, TerraModeler, and related tools.
• Classify point clouds into categories such as ground, vegetation, buildings, power lines, poles, and other relevant features.
• Perform ground and non-ground classification, noise removal, outlier detection, and point cloud refinement.
• Generate accurate terrain models, contours, elevation datasets, and 3D geospatial products.
• Integrate UAV imagery, LiDAR point clouds, GNSS/GPS data, and other geospatial datasets within GIS workflows.
• Conduct georeferencing, coordinate system transformations, data validation, and spatial analysis.
• Perform quality assurance and quality control (QA/QC) to ensure classification accuracy and compliance with project specifications.
• Prepare GIS maps, reports, deliverables, and technical documentation.
• Collaborate with surveyors, remote sensing specialists, and project teams to meet project timelines and accuracy requirements.

Required Technical Skills

• Strong knowledge of GIS, remote sensing, photogrammetry, and spatial data processing.
• Hands-on experience with TerraSolid software, particularly TerraScan and TerraModeler.
• Proficiency in LiDAR point cloud classification and editing workflows.
• Experience processing UAV/drone imagery and generating orthomosaics, DSMs, DTMs, and 3D surface models.
• Working knowledge of Bentley MicroStation or compatible point cloud processing environments.
• Proficiency in GIS software such as ArcGIS or QGIS.
• Knowledge of LAS/LAZ, GeoTIFF, SHP, DXF, and other common geospatial data formats.
• Understanding of coordinate reference systems, georeferencing, GNSS/GCPs, and spatial accuracy assessment.
• Strong analytical, problem-solving, and data quality management skills.

Preferred Qualifications

• Bachelor's or Master's degree in GIS, Geomatics, Geoinformatics, Remote Sensing, Civil Engineering, or a related field.
• Practical experience with UAV LiDAR or airborne LiDAR datasets.
• Familiarity with ground control points, checkpoint validation, and photogrammetric quality assessment.
• Experience in topographic mapping, corridor mapping, infrastructure mapping, or digital elevation modeling.
• Knowledge of Python or other scripting tools for geospatial workflow automation is an advantage.

Key Deliverables

• Classified LiDAR point clouds.
• Drone orthomosaics and 3D reconstruction products.
• Digital Terrain Models (DTM) and Digital Surface Models (DSM).
• Contour maps, elevation products, and GIS datasets.
• QA/QC reports and project-ready geospatial deliverables.
