GIS & Data Processing — geospatial layers and analytics

GIS & Data Processing

From raw imagery and survey data to clean, analysis-ready layers—orthomosaics, DSM/DTM, contours, vectors, and web maps—delivered in your coordinate system with QA and metadata.

GeoTIFF • LAS/LAZ • DWG/DXF GeoPackage • Shapefile • GeoJSON EPSG/CRS documented

Clean Data. Consistent Schema. Actionable Maps.

We standardize and QA every layer we produce—naming, fields, units, symbology—so your GIS or CAD teams can plug in and start analyzing immediately. Need a web map or dashboard? We package tiles and publish secure links for your stakeholders.

Typical workflows include orthomosaic creation, surface modeling, vectorization/digitization, feature extraction, spatial analysis, and publishing to web or enterprise GIS.

  • Orthomosaics

    Stitched, color-corrected GeoTIFFs aligned to control.

  • DSM/DTM & Contours

    Bare-earth models, surfaces & 0.25–1 m contours.

  • Vectorization

    Digitized features, breaklines, parcels & utilities.

  • Spatial Analysis

    Change detection, LULC, volumes, network/clip/overlay.

Capabilities

End-to-end processing—imagery, LiDAR/point cloud, vectors & analytics.

Orthos & Tile Packages

Cloud-optimized GeoTIFF (COG), MBTiles/XYZ/WMTS for web maps.

DTM/DSM & Contours

Surface cleaning, breaklines, hydro-enforcement and contouring.

Feature Extraction

Road edges, buildings, parcels, utilities, vegetation & water.

Point Cloud Processing

Classification, thinning, ground filtering, profiles & sections.

Spatial Analytics

Change detection, LULC, buffers/overlays, volume & cut-fill.

Web Maps & Dashboards

Secure links, role-based access, lightweight viewers for teams.

Process

How We Process

A consistent, audit-ready pipeline from ingest to publishing.

Step 01

Ingest & Align

Import photos/point clouds, apply control/checkpoints, set CRS.

Step 02

Clean & Derive

Denoise, classify, generate orthos, DSM/DTM, contours, vectors.

Step 03

Analyze & Publish

Run analytics, style layers, export packages, publish web maps.

FAQ

Quick Answers

Details on formats, CRS, and delivery options.

Which formats do you support?

Raster: GeoTIFF/COG; Vector: GPKG, SHP, GeoJSON; CAD: DWG/DXF; Point cloud: LAS/LAZ; Tiles: MBTiles/XYZ/WMTS.

How do you handle coordinate systems?

We adopt your EPSG/site grid and provide metadata with horizontal/vertical datums and units.

Can you publish a web map?

Yes—tile packages with a lightweight viewer and secure share link for stakeholders.

What about QA?

Checkpoint table with RMSE, schema validation, visual checks, and a PDF summary are included.
