Geospatial & Environmental
Contour analysis, watershed calculations, and renewable energy land requirements
Contour Area Calculator
Measure area from elevation contours or map traces. Calibrate with a scale bar or import coordinates/GeoJSON/DEM. Get acres, hectares, m², perimeter, and error bounds with exportable charts and PDF.
Watershed / Catchment Area
Estimate drainage area from a pour point using DEM-based flow directions and accumulation. Snap to streams, tune thresholds, and export area, perimeter, hypsometry, slope stats, charts, and PDF.
Solar Land Requirement
Estimate land needed for a solar project from target MW. Model fixed-tilt or single-axis tracker with GCR, tilt, pitch, setbacks, roads, and exclusions. Get acres per MW, area breakdowns, charts, and PDF export.
Wind Turbine Spacing
Estimate optimal wind turbine spacing, layout density, wake losses, and AEP. Model downwind/crosswind spacings in D, staggered vs rectangular patterns, setbacks, exclusions, and wind climate with a simple wake model.
Stormwater Runoff Volume Estimator
Estimate stormwater runoff volume using depth × area × runoff coefficient. Convert results to cubic meters, cubic feet, gallons, and acre-feet for drainage planning.
Retention Pond Size Estimator
Calculate retention pond storage volume and surface area to capture stormwater runoff. Estimate pond dimensions based on design depth and target capture fraction.
Basic Erosion Risk Index
Estimate erosion risk (0-100) based on slope steepness, soil erodibility class, and vegetation cover. Get risk category and factor contribution breakdown.
Off-Grid Solar + Battery Size Estimator
Estimate off-grid solar array size (kW, panels) and battery bank capacity (kWh, Ah) based on daily energy use, peak sun hours, system losses, and storage autonomy.
Rainwater Harvesting Tank Size Calculator
Estimate rainwater harvest potential from roof catchment area and calculate storage tank size based on daily demand and autonomy days. Results in liters, m³, and gallons.
