I provide expert GIS analysis using your or publicly available Digital Elevation Model (DEM) data to derive critical terrain and infrastructure features for any area. This service delivers a comprehensive geospatial package perfect for environmental planning, engineering projects, site selection, and landscape visualization.
My service includes a full workflow to transform raw elevation data into actionable layers:
Hillshade & Terrain Visualization: I will create high-resolution hillshade models to illuminate the terrain with realistic shading. This provides a 3D-like effect, crucial for map backgrounds, visual impact analysis, and understanding topography. Options for slope and aspect maps are also available.
Hydrological Network Delineation: Using advanced hydrology tools in ArcGIS or QGIS, I will process the DEM to accurately delineate the entire river and stream network. This includes calculating flow direction, flow accumulation, and defining the stream channels based on a specified threshold.
Road & Infrastructure Mapping: While roads are not derived from DEM data, this service integrates open-source data (like OpenStreetMap) or your provided datasets to extract the road network for your area of interest. The key value I add is conflating these layers—ensuring the roads and rivers are accurately overlaid on the hillshade terrain for a true-to-life representation.
You will receive a complete map package including:
A high-resolution, multi-layer GIS project file (e.g., .mxd, .qgz).
The processed raster and vector data layers (Hillshade, Rivers, Roads).
A professional, print-ready PDF map layout integrating all elements with a legend, scale, and north arrow.
My Key Differentiators:
Scientific Accuracy: My hydrological analysis follows proven terrain processing methods to ensure a realistic and accurate river network.
Efficient Data Fusion: I expertly combine the derived layers (hillshade, rivers) with external data (roads) into a single, coherent, and visually compelling product.
Clear Deliverables: I provide not just the raw data files, but also a finished map that is ready for immediate use in your reports and presentations.
Provide me with your area of interest, and I will turn elevation data into a clear story of the landscape.
