Enhancing Connectivity & Infrastructure

Coverage & Line-of-Sight

• Viewshed (Line-of-Sight) — maps where towers or repeaters can “see”; predicts shadowing by terrain/buildings; supports backhaul and RF planning.
  Products: Viewshed service using DEM or DSM.
• Terrain-based LOS for IoT/Smart-city — LOS modelling over dense terrain to ensure gateway coverage and sensor connectivity.
  Products: Terrain LOS modelling
• DEM/DSM/DTM — ground heights (DEM), surface incl. features (DSM), bare-earth terrain (DTM), feeding visibility and RF tools.
  Products:
  DEMSA2 L1 (2 m DEM),
  DEMSA2 L2 (DSM), DEMSA2 L3 (DTM),
  SUDEM5 (5 m).

Corridor Routing & Design transmission 

• Least-cost corridors — routes balancing slope, land-cover, wetlands and settlements for lines, ducts and roads.
  Products: Corridor suitability & least-cost path modelling
• Long-profile & grade checks — evaluate grades and turning constraints along candidate routes.
  Products: Add-Surface & profile tools (DEMSA2/SUDEM)
• Roughness | Position  — Terrain roughness describes variations in surface elevation, while position defines a location’s coordinates and relative height.  crucial for infrastructure design, autonomous navigation, and wind load analysis.
  Products: DEM derivatives (DEMSA2/SUDEM)
• Crossings & setbacks — stream order network, water-proximity and wetlands for crossing design & permits.
  Products: Stream Order Network; Distance-to water suites

Drainage & Water Management

• Flow Direction & Flow Accumulation — trace drainage paths and upslope contributing area to place inlets, culverts and attenuation.
  Products: Hydrology suite (DEM derivatives)
• Stream Network & Catchments — delineate channels, headwaters and sub-catchments for design & maintenance.
  Products: Stream Order Network; Catchment delineations
• HAND / FHI / TWI — screen low-lying and saturation-prone segments that threaten ducts, cabinets and platforms.
  Products: HAND, FHI, TWI

Earthworks, Contours & 3D

• Contours (50 cm vertical) — detailed contouring for alignment and platform layout; reduces cut-and-fill surprises.
  Products: Contours from DEMSA2 L3
• Slope | Curvature  — terrain derivatives for stability checks and constructability.
  Products: DEM derivatives (DEMSA2/SUDEM)
• 3D engineered model inputs — DTM, breaklines and surface packs for 3D design & machine control.
  Products: DEMSA2 L3 / SUDEM5 surface packs

Environmental & Compliance

• Protected & Conservation Areas — SAPAD/PACA overlays to flag no-go/low-impact zones for new towers, ducts and alignments.
  Products: Protected/Conservation Areas
• Land-use / Land-cover  — context for EIA, visual-impact and construction planning.
  Products: SANLC 2018 Land Cover
• Viewshed for visual impact — anticipate visibility to communities and viewpoints.
  Products: Viewshed service

Access, Admin & Integration

• Road networks — access and haul planning for construction and O&M.
  Products: Road Infrastructure layer
• Municipal districts/wards — reporting and permitting jurisdictions.
  Products: Admin boundaries
• API & CAD-ready delivery — web portal/API for live access; CAD/GIS formats for design tools.
  Products: GeoSmart API / Portal / CAD deliverables.
