I help engineering firms, researchers, and environmental teams turn raw spatial data — drone, satellite, LiDAR, or survey — into accurate, client-ready GIS and cartographic deliverables. My background spans SAR-based remote sensing research, agricultural GeoAI, and hands-on freelance delivery across topographic mapping, vegetation analysis, and geospatial automation.
What I do:
GIS Mapping & Cartography — professional maps for reports, publications, and engineering use; ArcGIS Online and Google My Maps web deployments; large-format, print-ready cartography with proper labeling, symbology, and visual hierarchy
Spatial Data Processing — polygon digitizing, georeferencing, coordinate system transformation, spatial joins, and clean Shapefile/GeoJSON/GeoPackage/DWG deliverables with full QA/QC
Remote Sensing & Environmental Analysis — LULC classification, vegetation mapping (NDVI, EVI, NDRE, TCARI/OSAVI), change detection, and flood/forest monitoring using Sentinel-2, Landsat, and drone imagery
LiDAR & Terrain Modeling — point cloud georeferencing, DTM/TIN generation, contour and spot elevation extraction, output to CAD (AutoCAD Civil 3D) and GIS formats with full X, Y, Z accuracy
GIS Automation — Python (GeoPandas, Rasterio, GDAL, ArcPy) pipelines for repeatable, scalable geospatial workflows, with results delivered in clean Excel reports
Tools: ArcGIS Pro, QGIS, Google Earth Engine, AutoCAD Civil 3D, CloudCompare, PostGIS, Python
I focus on getting the details right — coordinate accuracy, classification quality, and clean layer structuring — and communicate clearly from scope to delivery. Happy to share samples and talk through the best approach for your dataset.
