Wetlands Assessment
This environmental constraints project involved digitizing missing wetlands around a proposed factory site and producing a professional constraints map for rapid field-to-map traceability. Using color infrared aerial imagery as the base, the wetlands were digitized, symbolized, and attributed with WETL_ID and FLUCFCS codes, ensuring both scientific accuracy and usability for environmental decision-making. The map was prepared at a 1:4,800 scale with all standard cartographic elements, providing a clear assessment of ecological constraints in the area.
Key Metrics
-
Digitized eight missing wetlands from aerial imagery using ArcGIS.
-
Applied unique IDs (WETL_ID) and FLUCFCS codes to each polygon for standardized classification.
-
Calculated wetland acreage and ensured attribute accuracy via database joins.
-
Produced a map at 1:4,800 scale with neatline, north arrow, scale bar, and legend.
-
Exported final deliverable as a 300 dpi professional-quality PDF map.
Insights
Identification
How can digitized wetlands be classified and labeled for ecological assessment?
Mapping
How does cartographic clarity (scale, legend, labeling) support environmental review processes?
Planning
What acreage of wetlands exists in the project boundary, and how might this impact development plans?
