| SAGA Derivatives | Description |
| Aspect | Aspect is the compass direction that a slope faces, typically measured in degrees from north, and it influences microclimates and vegetation patterns. |
| Curvature | Curvature measures the rate of change of slope on a surface, indicating whether the terrain is concave (depressing), convex (elevating), or flat, which affects water flow and erosion patterns. |
| Distance to Nearest Drainage | Distance to nearest drainage measures the shortest distance from a given point on the terrain to the nearest water drainage feature, helping to identify areas of potential water flow and accumulation. |
| Flow Accumulation | Flow accumulation represents the total number of upstream cells or area contributing water flow to a specific point in a landscape, indicating potential water accumulation areas. |
| Flow Direction | Flow direction indicates the steepest path along which water moves from each point on a surface, typically represented as a grid of arrows pointing downhill towards the direction of water flow. |
| Flow Network | A flow network is a spatial representation of the interconnected pathways along which water flows across a landscape, including streams, rivers, and their tributaries, showing how water moves and accumulates through the terrain. |
| Height Above Nearest Drainage (HAND) 16000 Threshold | Height (meters) of each pixel with respect to the nearest stream that it drains to measures the vertical distance of each pixel’s elevation from the nearest stream or drainage feature, providing insight into the terrain’s gradient and potential water flow direction, with a threshold of 16,000 meters used to group and analyze pixels based on their relative height and proximity to these streams. |
| Plan Curvature | Plan curvature measures the rate of change of slope along a contour line, indicating whether the terrain is concave or convex in the horizontal plane, which influences water flow and erosion patterns. |
| Profile Curvature | Profile curvature measures the rate of change of slope along the direction of maximum slope, indicating whether the terrain is concave or convex in the vertical plane, which affects water flow speed and erosion. |
| Slope | Slope percentage represents the steepness of terrain, calculated as the vertical rise over the horizontal run, expressed as a percentage. |
| Stream Network 16000 Threshold | A stream network is a hierarchical system of interconnected water channels and tributaries that drain water from the landscape, with a threshold of 16,000 meters used to group and analyze the flow patterns and connectivity of these channels. |
| Topographic Wetness Index (TWI) | Topographic Wetness Index (TWI) quantifies the potential for water accumulation in a landscape based on the terrain's slope and the amount of upstream contributing area, indicating areas likely to be wetter or drier. |
| Solar Radiation | Solar radiation refers to the amount of sunlight received at a specific location and time, including both direct and diffuse components, which affects temperature, vegetation growth, and energy balance. |

Disclaimer
To ensure seamless and accurate data processing through our API, please adhere to the following rules and limitations:
- Interaction Limit: Each point or polygon query counts as a single interaction type.
- Coordinate Precision: ensure that the input coordinates are rounded to four decimal places and provided in Geographic Degrees using the WGS84 coordinate system.
- Multi-Point Selection: When selecting multiple points on the map, limit selections to fewer than 800 points.
- Polygon Draw: Limit the amount of polygons drawn on the map to fewer than 50 polygons, with additional area restrictions of 5km² per polygon.
- Upload Polygons: One file maximum upload, with the same limits as the polygon draw, applies.
- File Uploads: Uploaded CSV or Excel files must contain fewer than 801 rows including headers. Each file must conform to the following naming convention for columns: ID, custom unique identifier (optional), latitude, and longitude.
If these parameters do not suit your needs, please get in touch with the GeoSmart team directly for further assistance or a tailored package to suit your needs.
