Alberta, Canada
Han Zhang
I document survey, mapping and landscape work here as I build it — some pieces finished, some still in progress. Every project runs end to end from raw data to a checked, finished drawing, and I show the checks alongside the result, not just the polish.
How this works
Nine years of construction-drawing production in China taught the drafting discipline. After moving to Alberta, I've been rebuilding that discipline around Canadian data, standards and coordinate systems — the projects below are the result.
Open source first
Every project runs end-to-end on open tools (QGIS, PDAL/GDAL, Python) before I touch anything commercial, so the pipeline stays inspectable — I can show exactly how a result was produced, not just claim it.
Standards, not guesses
Design values come from the actual municipal and provincial standards, read before drawing starts and kept with their source document and page.
Checked, including the mistakes
Every automated step gets an independent check, and I publish the check results as they are — including where the first pass got something wrong.
Projects
Six pieces spanning survey drafting, geomatics and landscape construction. Two are finished with full drawing sets, interactive maps and downloads; the rest are underway.
Topographic survey to base plan
Survey & site topography
1,341 field shots checked, linework and TIN built, 1:500 topographic plan issued as DWG/PDF.
Real Property Report (RPR) sample
Property survey drafting
Building and fence positions relative to property lines, setback compliance check.
Wellsite survey plan sample
Wellsite survey drafting
Well centre, lease boundary and access road on the Alberta Township System.
Landscape construction drawings
Landscape design & construction drafting
Concept A for Wolfe Park: 284.9 m accessible loop, rain garden and planting on six ARCH D sheets; 0 trees removed, 28 of 36 QA checks passed.
LiDAR to DEM accuracy assessment
LiDAR & terrain analysis
Ground classification of public LiDAR compared with the source classification, and an accuracy report against check points.
GIS site analysis
GIS & site analysis
Slope, drainage, tree canopy and land-use analysis map set.
