What is Terrain Extractor Tool?
The Terrain Extractor Tool is a powerful, browser-based utility that connects to cloud-based GIS processing to extract specialized terrain features from global elevation datasets.
Instead of manually downloading heavy DEM files and processing them in desktop software like QGIS or ArcGIS, you simply upload your boundary, and our servers do the heavy lifting—returning ready-to-use vector KMLs and raster GeoTIFFs.
When Should You Use This Tool?
- •You need to quickly generate contour lines for a site plan without complex software.
- •You want to map the hydrological river network and stream flow of a specific watershed.
- •You need a color-coded slope map to analyze terrain steepness for construction or agriculture.
- •You require a fast, reliable source of SRTM 30m elevation data clipped perfectly to your project boundary.
How to Use Terrain Extractor Tool
- Upload your Area of Interest (AOI) boundary as a KML or KMZ file.
- Adjust the extraction parameters like Contour Interval, Slope Measurement, and River Extraction Level.
- The system automatically extracts the SRTM DEM data for your boundary.
- Once processing completes, your custom terrain data is ready to download.
- Click on the specific layer (Contours, Rivers, Slope, or Elevation) to download the file directly.
Real-World Use Cases
Hydrology & Drainage Planning
Use the extracted river networks and Strahler orders to understand water flow paths, plan drainage systems, and analyze watershed topologies.
Topographic Mapping
Download precise contour intervals to assist with 3D modeling, site surveying, and civil engineering project visualizations.
Agriculture & Land Management
Analyze the slope GeoTIFFs in degrees or percentage to determine land suitability for farming, planting, or machinery access.
