Cheatsheet
This page is for quick recall during practical execution.
Use this when you are actively working, not for detailed theory.
60-Second Start Check
- Project folder is inside OneDrive sync path.
- Working CRS is set to
EPSG:32643.
- Units are meters in CAD, GIS, and reporting.
- Raw files remain unchanged in a separate folder.
- Target communication outputs are PDF and KMZ.
CRS Cheatsheet
EPSG:32643: default projected metric CRS for this workshop.
EPSG:4326: latitude/longitude for Earth-browser exchange.
EPSG:3857: web basemap display CRS.
Rule: if AOI is outside UTM Zone 43N, switch to the correct UTM zone and keep it consistent everywhere.
Elevation Source Rule (Critical)
- Preliminary analysis without detailed survey: use Copernicus 30m DEM.
- Detailed analysis with detailed survey: convert survey to DEM and use that for contour/slope/profile.
- Label outputs with source tag (
copernicus30m or survey) to avoid mix-ups.
