I recently processed over 100,000 drone images covering approximately 10,000 hectares for Bridgmick Global Services. I delivered a Digital Terrain Model (DTM), orthomosaic, and contour maps that contributed to $20,000 in revenue during our first year of collaboration.
I help engineering, environmental, research, and property teams turn messy spatial data, drone imagery, satellite and aerial imagery, LiDAR point clouds, survey-control data, and field-survey files into accurate, ready-to-use GIS, CAD, and mapping deliverables. My background spans SAR remote-sensing research, remote sensing and Earth observation, agricultural GeoAI, terrain modelling, and vegetation mapping, backed by end-to-end GIS automation. I work with engineering firms, surveyors, researchers, and environmental teams that need dependable, accuracy-first geospatial support, the kind of work you can hand off and trust.
Remote Sensing & Earth Observation
I work with Sentinel-2, Landsat, and other satellite and aerial imagery sources through Google Earth Engine, applying computer vision and object detection to identify, classify, and map features such as land cover, vegetation, and change over time. I also review, annotate, and quality-check imagery and geospatial datasets to defined accuracy and QA standards, work that translates directly to imagery review, benchmarking, and domain-expert evaluation projects.
Coordinate Systems, Datums & Georeferencing
I establish and verify coordinate reference systems, horizontal and vertical datums (State Plane, UTM, GDA2020/MGA, and others), and survey control before any processing begins, because a mismatched datum, not a "bad" point cloud, is often the real source of error. I georeference drawings and imagery against cadastral boundaries, survey control points, and check points, apply similarity/affine transformations without distorting geometry, and document residuals and QA in a clear report. I convert cleanly between DWG, Shapefile, GeoJSON, and GeoPackage with no geometry loss.
LiDAR, Point Clouds & Terrain Modelling
I clean, classify, and georeference point clouds in QGIS, CloudCompare, and Civil 3D-compatible workflows; build DTM/DSM/TIN surfaces; and extract contours, spot elevations, breaklines, and existing-condition/topographic linework. I validate every surface and elevation against supplied survey control and benchmarks rather than adjusting data to "make it fit", and I document any adjustment that is made.
GIS Automation & Analysis
I write Python workflows using GeoPandas, Rasterio, GDAL, and ArcPy to automate repetitive GIS and geospatial-processing tasks, including data cleaning, raster and vector processing, and GeoJSON exports. I build PostGIS/PostgreSQL pipelines for spatial ETL, and I handle digitising, spatial joins, buffers and setback analysis, cadastral and parcel mapping, and density/demographic mapping (population, income, and other attribute-based mapping) for clean, presentation-ready outputs in ArcGIS Pro and QGIS.
CAD-to-GIS & Deliverables
I move data reliably between CAD and GIS, including DWG, DXF, GeoPDF, KML/KMZ, Shapefile, GeoPackage, and map-report formats, while preserving geometry, attributes, coordinate reference systems, and clear layer organisation. I produce print-ready maps and interactive web maps in ArcGIS Online, Mapbox, and Leaflet, and I'm comfortable working alongside licensed surveyors, matching an existing CAD/plot standard so my output drops straight into someone else's project without rework.
Tools: ArcGIS Pro, QGIS, AutoCAD Civil 3D, PostGIS, CloudCompare, Global Mapper, Google Earth Engine, Python, Mapbox, and Leaflet.
I communicate clearly, document my methods, flag assumptions or data limitations early, and treat accuracy in coordinate systems, classification, and final deliverables as non-negotiable. I'm happy to start with a trial and can share relevant samples on request.
