Remote Sensing & Space Sciences
City Survey uses satellite imagery from Landsat, Sentinel, MODIS, Maxar, Airbus and Planet, together with field data, to support engineering and planning studies. We process multi-spectral, thermal and time-series data to produce detailed assessments that can be directly used in planning, design and monitoring activities.
City Survey has built a strong reputation as a specialist provider of geospatial, surveying and engineering solutions. Over the past several years, we have expanded our technical capacity to support complex projects through satellite-based remote sensing, GIS analysis and integrated land information systems and are currently working with World Bank and Asian Development Bank .Our Remote Sensing Department consists of 126 dedicated specialists, including image analysts, GIS engineers & photogrammetry experts along with 500+ land survey professionals.
We specialize in the following types of studies using satellite data:
• Land use and land cover mapping for planning and environmental studies
• Monitoring changes in built-up areas, vegetation cover, barren land and water bodies
• Assessing urban expansion, encroachments and right-of-way developments
• Hydrological studies, including watershed delineation, flood mapping and sedimentation patterns
• Soil moisture and salinity analysis, terrain evaluation and environmental suitability studies
• Geological interpretation, lineament mapping and site-selection support for engineering projects
• Crop monitoring, NDVI vegetation assessments and water-stress analysis
• Urban heat-island assessment and thermal surface studies
• Shoreline monitoring, coastal erosion and mangrove health assessment
• Post-disaster mapping for floods, fires, landslides and other natural hazards
• Baseline environmental assessments and long-term change analysis
