Shades of Blue is a complete property reality-capture and interactive 3D experience built for a luxury villa in Thailand. The project combined exterior drone photogrammetry, detailed 3D reconstruction and interior 360° capture into a single explorable property experience. I handled the workflow from capture and processing through to the final interactive presentation, including: • Exterior UAV photogrammetry • Detailed textured 3D property model • Interior 360° walkthrough • Spatial navigation between rooms • Floor-plan and dollhouse-style views • Terrain and surrounding landscape context • Optimisation for an interactive web-based property viewer The goal was to let potential buyers and clients understand the entire property remotely — both inside and outside — in a way that standard photography cannot.

Cover image for Complete UAV photogrammetry and geospatial
Complete UAV photogrammetry and geospatial processing project for a hillside property in Thailand. I processed 1,272 aerial images in Agisoft Metashape Professional and QGIS, producing a high-resolution orthomosaic, dense point cloud, ground-classified terrain data, DTM/DEM, 0.5 m contours, elevation analysis and a detailed 3D reconstruction. The dataset generated more than 376 million dense points, including over 121 million ground-classified points, with mapping outputs at approximately 1 cm resolution. The final deliverables were prepared for practical land and property analysis, with clear visual outputs showing terrain, elevation, slope and site conditions.

Cover image for Reserved Land & Reserved Forest
Reserved Land & Reserved Forest Map – Pandalur & Nadugani Ranges This project focuses on mapping reserved lands and reserved forests in the Pandalur and Nadugani ranges under the Gudalur Forest Division. Using QGIS, I created a detailed administrative map including division, range, beat, and survey boundaries. I integrated forest classification data with terrain (slope) analysis to provide a clear understanding of land distribution and landscape characteristics. The map also highlights human settlements within and around forest areas, helping in planning, management, and decision-making. This project demonstrates my expertise in administrative mapping, boundary digitization, and geospatial data visualization for government and environmental applications. 👉 Available for administrative mapping and GIS projects.

Cover image for Professional GIS Mapping & Asset Digitization Services
Utility Mapping & Asset Digitization using GIS Description Accurate utility mapping is essential for infrastructure planning and asset management. In this project, I developed a comprehensive GIS-based utility map by integrating field-collected GPS data with spatial datasets. I digitized utility assets such as pipelines, electrical lines, and infrastructure features, ensuring proper alignment and georeferencing. Using ArcGIS and QGIS, I organized the data into structured layers, making it easy to analyze, update, and use for decision-making. The final output included clean, high-precision maps and GIS datasets (Shapefile/GeoJSON) that can be used for planning, maintenance, and future expansion of utility networks. This project highlights my ability to handle large datasets, ensure spatial accuracy, and deliver professional GIS solutions for real-world applications. 👉 Available for utility mapping, asset digitization, and GIS data management projects.

Cover image for Human–Wildlife Conflict Map Human–wildlife conflict is
Human–Wildlife Conflict Map Human–wildlife conflict is a major challenge in forest fringe areas. In this project, I analyzed conflict incidents across the Nilgiris landscape to identify high-risk zones and support better decision-making. Using ArcGIS and QGIS, I mapped human death incidents, wildlife presence (leopard, tiger, gaur, wild dog), and hotspot villages. I integrated terrain (slope), forest boundaries, rivers, and reservoirs to understand patterns of wildlife movement and interaction with human settlements. The analysis revealed that most conflict incidents occur near forest edges and buffer zones, especially in villages close to protected areas. Leopard activity was widely distributed, indicating higher interaction risk with human populations.This project demonstrates my ability to transform complex geospatial data into clear, actionable insights for forest management and conservation planning. 👉 Available for similar GIS mapping and spatial analysis projects. Feel free to message me.

Technologies for the carbon market In the map below, hydrograph drainage was generated using satellite imagery (Copernicus Global DSM 30m). The satellite imagery reveals that, in many cases where rivers and springs occur, the required vegetation cover is not properly maintained. With climate change, issues like this are becoming increasingly relevant. The carbon market has great potential for growth and improvement with the use of these technologies.

Cover image for Recently completed a GIS-based desktop
Recently completed a GIS-based desktop study for a gold exploration project in Pahang, Malaysia, covering areas around Lipis, Jerantut, and Raub. As a GIS Analyst, I worked on compiling and integrating multiple spatial datasets to support preliminary assessment and planning of potential exploration areas. The analysis and mapping included: • Regional geological mapping • Geomorphological analysis • Satellite imagery interpretation • Gold occurrence and resource visualization • Accessibility and surrounding area analysis • Quarry/resource mapping • Project planning and infrastructure mapping • Permit application mapping The workflow involved combining geological and mineral occurrence data with terrain, satellite imagery, road networks, waterways, and project boundaries to create clear and structured thematic maps for desktop-level assessment. The maps were developed using ArcGIS with a focus on consistent cartographic standards, spatial accuracy, and presenting complex geospatial information in a format that can support further exploration planning and decision-making. This project was a great opportunity to apply GIS not only for visualization, but also as a tool for integrating geological, environmental, and spatial information into a more structured exploration workflow. 📍 Pahang, Malaysia 🗺️ GIS Analysis & Cartography ⛏️ Gold Exploration Desktop Study

Cover image for Geomorphological Mapping Project | GIS
Geomorphological Mapping Project | GIS Analysis Just wrapped up a geomorphological mapping project for a site located in Pasir Gadung Village, Pandeglang, Banten. This work focuses on identifying landform characteristics and terrain variation to support better spatial understanding and decision-making. In this map, I combined elevation data, contour analysis, and spatial interpretation to classify geomorphological units—highlighting areas dominated by undulating hill formations. The red polygons represent the project activity zones, supported by coordinate points collected from the field. I also included a cross-section (A–B) to visualize terrain changes more clearly, giving a better perspective of slope variation and landform structure across the site. Tools & Approach: - GIS processing and spatial analysis - Contour and elevation modeling - Geomorphological interpretation - Map layout and visualization This kind of analysis is essential for projects related to land development, environmental assessment, and infrastructure planning. Always open to feedback and collaboration—let’s connect 🚀
