Frequently Asked Questions

Quick answers about land governance, GIS mapping, WebGIS publishing, survey services, and groundwater exploration.

Do You Provide High-Resolution DEM Data?

Yes. We deliver high-quality Digital Elevation Models (DEM) tailored to your project needs, including both Digital Surface Models (DSM) and Digital Terrain Models (DTM). Our elevation data supports precise planning, engineering design, and advanced spatial analysis across urban, regional, and infrastructure projects.

Can You Provide Bare-Earth and Surface Elevation Models?

Absolutely. We offer bare-earth terrain models (DTM) for hydrology and engineering applications, as well as surface models (DSM) that include buildings and vegetation for 3D analysis and infrastructure planning. You receive the exact elevation product suited to your objective.

Is Your DEM Data Suitable for Flood and Watershed Analysis?

Yes. Our hydrologically optimized elevation datasets improve the accuracy of flood modeling, watershed delineation, and drainage analysis. This ensures better decision-making for risk assessment, disaster management, and infrastructure protection.

Do You Offer Derived Products Like Contours and Slope Maps?

Certainly. In addition to base DEM data, we provide value-added terrain products such as contour maps, slope and aspect layers, hillshade models, and other elevation-derived analytics to support design, planning, and environmental studies.

Can DEM Data Support 3D Visualization and Infrastructure Planning?

Yes. Our elevation datasets are fully compatible with GIS, CAD, and 3D visualization platforms, enabling accurate terrain modeling, route profiling, and infrastructure analysis for engineering and development projects.

How Is DEM Data Delivered to Clients?

We provide DEM datasets in standard GIS-compatible formats such as GeoTIFF and other widely used formats. Data delivery is secure, efficient, and structured for immediate integration into your existing GIS or engineering workflow.
