1. Reclassify
Reclassify raster values into categories.
Reclassify [raster_layer] into categories: values 0-10 become class 1, 11-50 become class 2, 51-100 become class 3. Create a new classified raster.
2. Raster Calculator
Perform mathematical operations on rasters.
Calculate [raster_1] + [raster_2] and create a new raster with the sum of cell values. Handle NoData values by treating them as zero.
3. Slope Analysis
Calculate terrain slope.
Calculate the slope from [elevation_raster]. Output slope in degrees. Visualize with a color ramp from green (flat) to red (steep).
4. Aspect Analysis
Calculate terrain aspect/direction.
Calculate aspect from [elevation_raster]. Show which direction each cell faces. Color by compass direction: north=blue, east=green, south=yellow, west=red.
5. Hillshade
Generate hillshade visualization.
Create a hillshade from [elevation_raster]. Use sun azimuth of [degrees] and altitude of [degrees]. Apply to create a 3D terrain effect.
6. Contour Generation
Create contour lines from raster.
Generate contour lines from [elevation_raster] at [interval] meter intervals.
7. Zonal Statistics
Calculate statistics for zones.
Calculate [sum/mean/min/max] of [value_raster] within each zone defined by [zone_layer]. Add the statistics as attributes to the zones.
8. Raster to Vector
Convert raster to vector features.
Convert [raster_layer] to vector polygons. Create a polygon for each contiguous area with the same cell value. Simplify the resulting polygons.
9. Resample
Change raster resolution.
Resample [raster_layer] to [new_resolution] meter resolution. Use [nearest/bilinear/cubic] interpolation method.
10. Mosaic
Combine multiple rasters.
Mosaic [raster_1], [raster_2], and [raster_3] into a single raster. Handle overlapping areas by using the [first/last/mean] value.
