GIS Mapping | LiDAR | Georeferencing | Digitizing | Spatial Data

GIS Mapping Specialist experienced in creating, editing, validating, and processing spatial data for mapping, infrastructure, field operations, and location-based projects. I work primarily with ArcGIS Pro and QGIS, with experience handling vector data, georeferencing, digitizing, geocoding, spatial analysis, DEMs, KML/GeoJSON, and LiDAR-based mapping workflows. Core GIS services include: • GIS data creation and editing — points, lines, polygons, shapefiles, GeoJSON • Georeferencing and digitizing historical, scanned, and PDF maps • Geocoding and reverse geocoding • Spatial data cleaning, validation, and quality checking • LiDAR point cloud interpretation and BEV spatial segmentation • Driveable/non-driveable area classification from LiDAR data • Elevation, terrain, and DEM-related mapping • Infrastructure, utility, road, parcel, and land-use mapping • Traffic intersection and lane configuration mapping • OSM/JOSM-based building and infrastructure mapping • CAD drafting and topographic mapping • KML creation and editing for Google Earth • Mobile-ready GIS data preparation including GeoJSON and MBTiles • Location research and spatial data collection using Google Maps Tools: ArcGIS Pro | QGIS | JOSM | Google Earth | Microsoft Excel I focus on producing clean, consistent, and practical spatial data that is ready for analysis, visualization, or further GIS processing. Available for both short-term GIS tasks and ongoing projects.
