At XYZ Mapping Agency we were tasked with visualizing population density for a regional planning report.

Create a clear, accurate thematic map that highlighted density variations across districts.

I cleaned the raw census shapefile, performed natural breaks classification in ArcGIS, chose a sequential color ramp for readability, added a legend and scale bar, and exported the map as a high‑resolution PDF.

The final map was adopted by the planning department, praised for its clarity, and helped prioritize infrastructure investments.

While working on a cross‑border transportation project, I received road network data in NAD83 and demographic data in WGS84.

Integrate both layers accurately for spatial analysis.

I identified the target projection (UTM Zone 15N), used the Project tool in QGIS to reproject the NAD83 road layer, and applied on‑the‑fly transformation for the WGS84 demographics, ensuring datum consistency. I then performed a topology check to catch any misalignments.

The integrated dataset enabled precise route optimization, and the client reported a 15% reduction in travel time estimates.

Our team was commissioned to create an interactive map for a city’s public transit app.

Design a map that loads quickly, remains legible on small screens, and supports touch interaction.

I simplified symbology to essential icons, used vector tiles to reduce file size, implemented responsive labeling that hides low‑priority labels at higher zoom levels, and conducted usability testing with a focus group of commuters.

The app achieved a 30% faster load time and received positive feedback for readability, leading to a 20% increase in daily active users.

During a flood response, the emergency management agency needed an updated flood risk map within 48 hours.

Produce an accurate, up‑to‑date map showing affected zones for rescue planning.

I coordinated with the hydrology team to obtain latest water level data, used rapid GIS scripting in Python to reprocess DEMs, applied automated symbology, and held briefings with the agency to validate key areas.

The map was delivered on time, enabling efficient deployment of resources and was credited with saving lives in the affected region.

A real‑estate developer wanted to understand site suitability analysis for a new project.

Explain the GIS‑based suitability model in plain language.

I used analogies comparing layers to transparent sheets, created a simple storyboard with visual examples, and avoided jargon by referring to ‘risk levels’ instead of ‘standard deviation’. I also provided a one‑page summary with key takeaways.

The client approved the project plan confidently and praised the clarity of the explanation.

A heritage organization provided 200 scanned topographic sheets for digitization.

Convert the raster scans into georeferenced vector layers usable in contemporary GIS applications.

I performed batch georeferencing using control points from known benchmarks, applied image enhancement to improve line clarity, digitized contour lines and features into vector shapefiles, standardized attribute schemas, and stored the results in a spatially enabled PostgreSQL/PostGIS database.

The digitized dataset became searchable, supported overlay analysis with current satellite imagery, and was incorporated into the organization’s public web map portal.
