Africa's most critical assets pipelines, bridges, reservoirs, forests, agricultural zones, coastlines cannot be monitored by putting a person on the ground every day. Remote sensing and IoT-based monitoring fill that gap, providing continuous, automated observation of conditions that matter, flagging anomalies before they become failures, and generating the long-term datasets that underpin sound evidence-based decision-making.
Dali Geotech Ltd designs and deploys integrated monitoring systems that combine ground-based IoT sensors, drone surveys, and satellite imagery analysis into unified platforms delivering actionable alerts and trend data to the people responsible for managing Africa's infrastructure and natural resources, wherever they are.
The most powerful monitoring systems combine what sensors on the ground measure with what satellites observe from above. Our platforms fuse IoT telemetry water levels, soil moisture, structural vibration, temperature, air quality with satellite-derived indicators such as vegetation health indices, surface water extent, land cover change, and thermal anomalies. The result is a multi-layered picture of reality that neither source alone can provide, updated continuously and accessible through a single web dashboard from any device.
A complete end-to-end remote monitoring capability from sensor hardware and satellite data acquisition through to alert systems, dashboards, and long-term trend analysis.
Design, procurement, installation, and configuration of IoT sensor networks for environmental, structural, and operational monitoring including solar-powered nodes with LoRaWAN, NB-IoT, or 4G connectivity suited to remote African sites.
Automated analysis of multi-temporal satellite imagery Sentinel-1/2, Landsat, PlanetScope to detect and quantify land cover change, deforestation, flood extent, coastal erosion, and urban expansion at defined intervals.
Scheduled drone flights for high-resolution visual inspection of infrastructure, crop fields, construction sites, and conservation areas with photogrammetric outputs including orthomosaics, DSMs, and 3D point clouds.
Configurable alert engines that trigger SMS, email, or in-app notifications the moment a monitored parameter crosses a defined threshold enabling rapid response before minor anomalies escalate into critical failures.
Custom web dashboards that display live sensor readings, satellite-derived indicators, trend charts, and alert histories with automated periodic reports for operations teams, management, and donor stakeholders.
Structured time-series data archives that grow in value over years enabling retrospective analysis, seasonal pattern recognition, and the longitudinal evidence base required for climate adaptation planning and impact evaluation.
Our monitoring systems are deployed across six core domains each with specialised sensor selections, satellite data products, and analytical frameworks tailored to the specific observational challenges involved.
Continuous monitoring of bridges, dams, retaining walls, pipelines, and buildings using vibration sensors, inclinometers, crack gauges, and strain monitoring detecting structural deterioration before failure occurs.
River level gauges, reservoir volume tracking, groundwater depth monitoring, rainfall stations, and satellite-derived surface water mapping supporting early flood warning, water utility operations, and catchment management.
Near real time deforestation alerts using Sentinel-1 SAR and optical imagery, combined with ground-based camera traps and acoustic sensors used by conservation organisations, carbon project developers, and government forestry departments.
Soil moisture probes, weather stations, and NDVI-based crop health monitoring from satellite imagery helping agri-businesses, irrigation schemes, and food security programmes track growing conditions in real time.
Distributed air quality sensor networks measuring PM2.5, PM10, NO₂, CO, and ozone deployed in urban centres, near industrial facilities, and in climate monitoring networks to track pollution exposure and regulatory compliance.
Smart metering, solar generation monitoring, grid fault detection, and transformer health tracking giving utilities and off-grid energy operators continuous visibility into system performance and loss identification.
A structured four-stage approach that takes you from defining what needs to be watched, to having a live, alerting monitoring system your team can depend on.
We work with your team to identify the critical parameters, risk thresholds, and reporting requirements then design the sensor network, satellite data layers, and alert logic that will meet those needs.
Our field engineers install and commission sensor hardware on-site, configure data transmission, and validate readings against calibrated reference instruments before going live.
Sensor streams and satellite data are integrated into a unified monitoring platform with dashboards configured, alert thresholds set, and automated reports scheduled for your key stakeholders.
We provide ongoing platform support, sensor maintenance visits, battery and calibration checks, and periodic analysis reviews ensuring data quality and system reliability over the full project lifecycle.
We have deployed remote monitoring solutions across a wide range of African operating environments — here are some of the problems we have been trusted to solve.
Continuous seepage, settlement, and piezometric monitoring for irrigation dams and hydropower reservoirs with automated alerts to operations centres when safety thresholds are approached.
River level sensor networks integrated with rainfall data and satellite derived catchment models providing downstream communities and civil protection agencies with 6–24 hour advance warning of flood events.
Near-real-time deforestation detection for REDD+ and voluntary carbon market projects providing the independent, auditable monitoring records required for carbon credit verification under international standards.
Satellite change detection and drone patrols along oil, gas, and water pipeline corridors identifying encroachment, illegal tapping, ground movement, and vegetation clearance that signal potential integrity threats.
Soil moisture and weather station networks across irrigation command areas combined with satellite crop health indices to optimise water allocation, detect waterlogging, and maximise yield per hectare.
Low-cost sensor networks deployed across city wards to map pollution hotspots, track seasonal trends, support public health research, and provide the evidence base for clean air policy and enforcement.
We select hardware and software based on performance in African field conditions prioritising low-power operation, ruggedised form factors, and connectivity options suited to remote sites.
