Urban GIS & Location Intelligence

Turning Urban Data into Clear, Scalable Insights

GIS-powered urban dashboards • Big data & scalable systems • Cost-efficient, high-performance mapping

I design geospatial systems that help organizations understand cities from land and housing to infrastructure and accessibility. My work turns complex urban data into practical insights for planning, investment, and operations.

How I Solved the Urban Problems

Handling millions of building records can slow down systems and make maps hard to use. The original workflow relied on manual digitization in desktop GIS accurate, but slow and not scalable.

Step 1: Use Existing Open Data

Instead of manually digitizing buildings, I sourced data directly from OpenStreetMap using the Overpass API saving time and leveraging a maintained global dataset.

Step 2: Reduce Data Size

I applied bounding boxes to load only buildings within the user's area of interest, reducing payload size and improving load speed.

Step 3: Modern Web Mapping

I used MapLibre for its lightweight architecture, smooth rendering, and open-source flexibility which is ideal for large spatial datasets.

Step 4: Improve User Interaction

The map supports 2D and 3D views, geolocation, and search, allowing users to explore building data intuitively.

Step 5: Optimize Performance

By combining automated data, filtering, and modern rendering, the final system loads faster, scales better, and replaces manual GIS workflows.

This approach delivers a faster, cleaner, and more scalable solution compared to traditional desktop GIS digitization saving time and cost while improving usability.

About Me

Hi, I'm Joshua De Leon from the Philippines. I work remotely at the intersection of urban systems, real estate, and geospatial technology. I help organizations understand how cities function from land and housing to accessibility, infrastructure, and site visibility turning complex spatial data into actionable insights.

I design scalable WebGIS platforms capable of handling large datasets, making location intelligence accessible to decision-makers, analysts, and organizations. My solutions support site selection, housing analysis, land use planning, and workflow automation, bridging technical expertise with practical impact.

My mission is to empower real estate developers, urban planners, and organizations to make smarter, data-driven decisions using modern geospatial tools that simplify the complexity of cities into clear insights.

Urban GIS & Automation Services

I help organizations increase revenue opportunities, reduce operational costs, and improve efficiency by modernizing mapping and spatial data workflows through scalable, database-driven Web GIS systems.

City-Scale Mapping & Visualization
