01 · PREPARE
Imagery and control review
Review image sets, naming, overlap and available control information before production and flag gaps that could affect completeness.
IMAGE PROCESSING · ORTHOMOSAICS · ELEVATION PRODUCTS
Convert imagery into measurable mapping data.
We support photogrammetry production workflows using client-supplied aerial or terrestrial imagery and agreed project controls. Processing may include image preparation, reconstruction review, orthophoto outputs and elevation products for mapping and engineering use.

IMAGERY TO MAPPING
OUR APPROACH
A structured workflow from source data to usable deliverables.
Photogrammetry deliverables depend on image coverage, overlap, image quality, camera information and available control. We align the processing workflow with the intended map scale, ground sampling distance and downstream use.
02 · PROCESS
Reconstruction and mapping outputs
Support image alignment, dense reconstruction and orthomosaic or elevation-product preparation within the agreed software workflow.
03 · VERIFY
Coverage and deliverable QA
Check completeness, seam areas, obvious distortions, coordinate information and file naming against the delivery checklist.
FROM IMAGES TO MAPPING PRODUCTS
How photogrammetry becomes measurable data.
Photogrammetry reconstructs three-dimensional information from overlapping images. Output quality depends on image sharpness, overlap, camera geometry, surface texture, control and processing settings.
Image alignment and bundle adjustment
Detect and match image features, estimate camera positions, and review alignment quality before dense reconstruction. Weak overlap, blur or repetitive textures can create gaps or distortions.
Dense point cloud and surface models
Generate a dense point cloud or mesh, then prepare DSM/DTM products where the source data and terrain conditions support them. Water, shiny surfaces and vegetation can be difficult to reconstruct reliably.
Orthomosaics and deliverable QA
Produce georeferenced orthomosaics, review seams and visible artifacts, confirm coordinate reference and resolution, and document agreed checks. GCPs and independent checkpoints should be used as required by the project accuracy plan.
Useful inputs:
Overlapping source imagery, camera information when available, coordinate reference, ground-control/checkpoint files where required, target resolution, output format and the acceptance criteria for the final products.
VISUAL WORKFLOW / EXAMPLE OUTPUTS
See the data take shape.
Illustrative outputs from related geospatial workflows. Final deliverables are agreed to the project specification.
