Page: https://globalmapping.biz/en/sectors/territory-and-environment --- ## Territory and Environment Sector # Mapping and cadastre for environmental studies and land-use planning We produce the terrain models, orthophotos and thematic maps each study needs, and measure what changed from one campaign to the next. Since 1999 we have surveyed more than 5 million hectares. An environmental study, a cadastre or a land-use plan is discussed over a map, and that map is reviewed by the authority, the project owner and often the local community. So what we deliver is tied to the official geodetic network, inside a geospatial database another specialist can open and check. Then comes the follow-up: deforestation, land-use change, erosion, debris flows and landslides. Satellite imagery covers large areas and shows land-cover change well, but it cannot see the ground under the forest. To measure the ground beneath the canopy, we fly LiDAR. Experience and results 5M+ hectares surveyed 1200+ projects delivered 200+ clients ## Where we work in territory and environment ### Land-use planning Base mapping, terrain models and spatial analysis for the plan and its follow-up. ### Urban and rural cadastre Parcel surveys, land title regularization and a geospatial database. ### Land cover and land use Multispectral remote sensing and land-cover classification with change detection. ### Protected natural areas Boundary delineation, buffer zones and deforestation monitoring. ### Environmental liabilities and closure Inventory, volume calculations and multitemporal tracking of closure plans. ### Watersheds and risk zones Hazard, vulnerability and risk mapping for preventive management. ## Four business lines, from planning to monitoring Plan, design, build, operate and monitor. The same four lines in every sector, with the activities and deliverables that sector needs. 01 Levantamiento, Cartografía y Modelado ### Survey, Mapping & Modeling “From a single parcel to a whole watershed, we survey the ground and its vegetation” - Airborne, terrestrial, mobile and drone LiDAR of the ground and its vegetation cover - Surveying, geodesy, GNSS networks and precise leveling - Digital photogrammetry, orthophotos and DTM and DSM models - Remote sensing and multispectral satellite imagery for land-cover and land-use analysis - Digital mapping, thematic maps and terrain modeling - Hydrographic and bathymetric surveys of water bodies and riverbank buffer strips - 3D modeling and digital twins of the ground and its infrastructure - Urban and rural cadastre, land management and land regularization - Delineation of protected natural areas, concessions and buffer zones Deliverables Classified point cloud · DTM/DSM · High-resolution orthophoto · Thematic land-cover and land-use maps · Cadastral plans and maps · 3D models · Geospatial database (GDB) 02 Control y Aseguramiento de Calidad ### Quality Control & Assurance “We cross-check cadastre, maps and official sources until they agree” - Geodetic control and official georeferencing of land and environmental studies - Geometric verification and positional quality control of surveys and maps - Independent audits of topographic, LiDAR, photogrammetric and satellite surveys - Geospatial QA/QC to international standards and project specifications - Validation of geospatial databases and their topological consistency - Reconciliation of cadastral, land and environmental data across official sources - Validation of geospatial data for technical dossiers and environmental studies Deliverables Geodetic control report · Geometric verification record · QA/QC report (ISO 19157 / ASPRS) · Topological consistency report · Reconciliation drawings · Independent audit report 03 Monitoreo del Territorio y Gestión de Riesgos Ambientales ### Land Change & Environmental Monitoring “We measure how much forest was lost and how much soil eroded between campaigns” - Multitemporal monitoring with LiDAR, drones, GNSS and satellite imagery for change detection - Tracking of deforestation, erosion and land-cover and land-use change - Monitoring of slope stability, landslides and geological risk zones - Assessment and follow-up of environmental liabilities and closure plans - Hazard, vulnerability and risk mapping for land management - Monitoring of water bodies, riverbank buffer strips and flood-prone areas - Instrumentation, GIS and spatial analysis combined for preventive risk management Deliverables Multitemporal change reports · Deforestation and land-cover maps · Hazard, vulnerability and risk maps · Environmental monitoring reports · Threshold-based technical alerts · Risk management reports 04 Soluciones Digitales e Inteligencia Artificial ### Digital Solutions & Artificial Intelligence “We classify land cover with AI and publish the maps on your GIS platform” - Digital twins of the territory, updated with each monitoring campaign - GIS platforms and spatial data infrastructures (SDI) to manage and publish land information - Automatic land-cover classification and change detection with artificial intelligence - Geospatial dashboards to track land and environmental indicators - 3D virtual tours for inspection, planning and remote participation - Predictive analysis and AI to anticipate environmental risks and pressure on the land Deliverables Digital twin of the territory · Integrated GIS / SDI platform · Geospatial dashboard · Predictive models and automated reports · 3D virtual tours ## Who we work for - Environmental authorities - Regional governments - Local governments - Environmental consultancies - Project owners - Social and land-management teams - Banks and investors - GIS and remote-sensing specialists ## Brochure ## Download the sector brochure Leave us your details and download the sector brochure, with our lines of work, activities and deliverables.
