Spatial Data Visualization & AI Workflow Systems
Cover image for From static maps → interactive
From static maps → interactive spatial experiences. 🚀 Recently experimented with building a Geo-inspired commute dashboard using Vibe Coding + geospatial visualization. The interesting shift for me: Instead of spending days moving between GIS software, frontend development, and UI iteration, ideas can become working interfaces much faster. Still early, but it opens up interesting possibilities: → spatial analytics that feel more accessible → interfaces ready for predictive layers and AI workflows → reducing the barrier between geographic data and end users Curious where GIS + AI + Vibe Coding goes next.

Cover image for One of the most interesting
One of the most interesting shifts in AI right now: Real estate AI systems are only as smart as the spatial data behind them. Just wrapped up a GeoAI-oriented automation project for large-scale parcel intelligence in Australia. Built a standalone workflow that automatically detects: → frontage roads → corner lots → parcel orientation → multi-road adjacency → spatial access relationships The interesting part wasn’t the GIS itself. It was converting messy spatial relationships into structured knowledge that downstream AI systems can actually understand. A lot of “AI for real estate” conversations focus on LLMs. But the real bottleneck is often: How do you turn geography into machine-readable reasoning context? Ended up packaging the entire workflow into a production-ready executable app for non-technical teams, with batch processing + configurable spatial rules. Feels like we’re moving from: “mapping data” to “building spatial reasoning infrastructure.” #GeoAI #PropTech #SpatialComputing #Automation #GIS #AIInfrastructure

Cover image for I create interactive 3D city
I create interactive 3D city visualizations showing how urban areas evolve over time. Using Kepler.gl (http://Kepler.gl), building footprint data is visualized in 3D with a time slider based on construction year, revealing the growth of a city. Each building is clickable and includes a direct link to street-level imagery in Google Street View, allowing users to explore the real-world view of the building. This visualization is ideal for urban planning, real estate analysis, city storytelling, and digital twin presentations.

Cover image for 🚀 Most people calculate driving
🚀 Most people calculate driving distances one route at a time. That doesn’t scale. I built an Excel-based tool that automates distance and travel time calculations for large datasets using an API. You can input hundreds of origin–destination pairs and get: ☑️ Distance (miles/km) ☑️ Travel time (minutes) ☑️ All processed in bulk, directly in Excel. This is particularly useful for: ☑️ Freight pricing models ☑️ Logistics planning ☑️ Route analysis ☑️ Location-based datasets What used to take hours can now be done in minutes. Happy to share more details or customize it for specific workflows. https://contra.com/s/eFoEEFRF-bulk-driving-distance-and-time-calculator-excel-api-automation

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 🚀

Cover image for 🗺️ Web GIS for Field
🗺️ Web GIS for Field Operations & Location-Based Data Collection I developed an interactive geospatial platform designed to help teams visualize, manage and update field-work information directly on a map. The application combines Web GIS, satellite imagery, spatial data management and field reporting in a single workflow. Key capabilities include: • Interactive field map with spatial work areas • Color-coded work / prescription classifications • Multiple GIS sub-maps and project views • Satellite and OpenStreetMap basemap switching • Work completion and status tracking • Location-based field-point creation • GPS coordinate capture • Field categorization and notes • Photo attachment support for field observations • Map-based project and team workflows The goal is to replace disconnected field records with a centralized spatial workflow, where teams can see exactly where work is required, record observations from the field, and maintain geographically accurate project information. Built around Web GIS, spatial databases and interactive mapping. Interested in projects involving GIS development, field-data collection, asset management, spatial dashboards and geospatial workflow automation.

Cover image for 🚗🌍 Can a navigation system
🚗🌍 Can a navigation system recommend the most fuel-efficient route instead of simply the shortest one? This project was developed as part of my MPhil Remote Sensing & GIS thesis. I designed and developed an intelligent Web GIS routing system that generates and compares four alternative routes between an origin and destination and recommends the most suitable route using a Multi-Criteria Decision-Making (MCDM) approach. Instead of considering only distance, the system evaluates multiple factors such as: • 🌱 Fuel-efficiency / environmental suitability • ⏱ Travel duration • 🚧 Road hurdles and route conditions • 📏 Travel distance The alternatives are evaluated using a TOPSIS-based decision model, allowing the system to identify the route with the best overall balance rather than simply choosing the shortest path. I also integrated an AI assistant that explains route recommendations in natural language, helping users understand why one route is preferable to the alternatives. Key features: • Interactive Web GIS navigation • Four-route generation and comparison • MCDM/TOPSIS route ranking • Fuel-efficient route recommendation • Route distance and travel-time analysis • Road-condition / hurdle consideration • AI-generated route explanations • Interactive route visualization • Decision-support interface for sustainable mobility Built with Python, Django, GIS, Leaflet/OpenStreetMap, MCDM and AI integration. This research explores how GIS + decision science + AI can support smarter and more sustainable urban mobility.
