Hire the Best QGIS Specialists
in the United States

I'm a GIS analyst and cartographer with 8+ years of experience translating complex environmental, social, and operational data into maps and dashboards that actually get used. I've built interactive Tableau and ArcGIS Online tools for nonprofit disaster response, developed climate visualizations for international NGOs, and mentored students at Columbia University's School of Professional Studies and Climate School. My work has been featured at the Data Visualization Society's Outlier Conference. I work best with organizations where the data matters - environmental nonprofits, sustainability initiatives, climate advocacy groups, public agencies, and mission-driven teams. Whether you need a polished static map for a report, an interactive web map for stakeholders, or a Tableau dashboard that tells a story, I bring both the technical depth and the communication skills to get you there. My approach is equity-focused, collaborative, and delivery-oriented. I'll ask the right questions upfront so the final product fits your audience, not just your dataset.

I provide engineering-grade terrain models, quantity analysis, and spatial data used for pre-design, site feasibility, construction planning, and field verification. My work supports civil engineers, surveyors, developers, insurers, and property owners who need reliable surfaces, measurements, and documentation without overcomplicating the process. Typical deliverables include DTM/DSM surfaces, cut/fill and earthwork quantities, contours, LandXML/DWG files, GIS outputs, and drone-based mapping or inspection documentation. I regularly work with AutoCAD Civil 3D, LiDAR, photogrammetry, GIS/QGIS, and Virtual Surveyor–style quantity workflows, producing data that integrates cleanly into downstream engineering, planning, or decision-making. In addition to office-based analysis, I also perform drone and on-site inspection work, including property and insurance-related inspections, condition documentation, and site verification. These projects often involve rapid turnaround, clear photo and map deliverables, and defensible measurements that insurers, adjuster networks, and asset managers can rely on. With over 14 years of experience supporting surveying and engineering workflows, I’m known for accurate data, practical execution, and clear communication. Whether you need terrain and quantities for design, site intelligence for planning, or reliable field documentation for inspection or insurance purposes, I bring a no-nonsense, professional approach focused on getting usable results fast.

I’m a GIS Application Analyst with experience supporting both government agencies and private-sector clients, giving me a practical understanding of how spatial data is used in real-world decision-making. I specialize in automating GIS workflows, building ETL pipelines, and delivering accurate spatial analysis that saves time and improves data reliability. Whether you need help cleaning and transforming data, analyzing geographic patterns, or streamlining repetitive GIS tasks with Python and SQL, I can deliver efficient, scalable solutions.

I have a Bachelors in Geography and Masters in GIS. With 13+ years of experience I can confidentially do any GIS related tasks. Experienced in creating various thematic maps, GIS automatization with Python, 3D modelling, remote sensing (LIDAR, aerial and satellite imagery) etc. I am proficient with ArcGIS Pro and ArcGIS online applications and webmaps including but not limited to ArcGIS Online, ArcGIS Experience and ArcGIS Webapps. I am enthusiastic about what am I doing and always open to new areas. I like new challenges, which can push my knowledge and skills to new levels.

Hi, my name is Pete Coventry and I'm a GIS Professional with over 22 years experience in the GIS/Geospatial fields in both public and private sectors. Of my 22 years experience, 10 years have been at a County Assessor's Office where I was a GIS Specialist. I focused on parcel level analysis pertaining to legal descriptions, ownership, property valuations and data mining. I'm fluent in ESRI ArcMap 10x, ArcGIS Pro 2x, ArcGIS Online, QGIS 3x, Umap and Mapbox mapping platforms and python scripting. When not at my desk, I'm a FAA Certified Drone Pilot flying a DJI Mavic 2 Pro to cover a variety of aerial done photography. I'm using Lightroom, Photoshop, Hugin, and DJI GO 4 software. I have a Master's Degree and a Graduate Certificate both in GIS. I'm actively involved in several geospatial professional groups, presented my work at several geospatial conferences and continue to learn in this ever growing field. I'm a firm believer in finding the best solution, whether it's Open Source or proprietary mapping software. Please feel free to contact me with any questions. Thanks, Pete
