Mobile mapping and 3D urban reality

SLAM and 3D LiDAR mapping for cities and infrastructure.

Dashify surveys streets and urban corridors, reconstructs the environment as a point cloud, and delivers poles, arms, trees, sidewalks, facades and signs as measurable georeferenced data.

SLAM locates the system while LiDAR measures the world around it.

The result is more than a sequence of photographs. It is a continuous three-dimensional representation of the surveyed corridor, linked to a trajectory and prepared for control, classification, measurement and geographic-system integration.

SLAM

Simultaneous localization and mapping

SLAM estimates equipment motion while registering new observations into the same map. It reduces exclusive reliance on GNSS and helps preserve continuity under trees, near buildings, in passages or where satellite signals degrade.

LiDAR

Laser pulse measurement

LiDAR measures the return time of light pulses to calculate distances. Millions of readings form a 3D point cloud that represents surfaces, heights, volumes and clearances.

FUSÃO

Sensors working together

LiDAR, an inertial unit, GNSS and panoramic imagery can be combined to stabilize the trajectory, add visual context, control quality and place the survey in the project's coordinate system.

Vehicle mobile mapping

More field coverage without reducing the urban corridor to isolated points.

The mobile system records complete geometry as the vehicle travels. Teams can review, measure and classify in the office, reducing repeated traffic exposure and making inventory updates more consistent.

Continuous acquisition

Streets and avenues are captured as connected corridors instead of requiring manual measurement of every asset during the initial pass.

Complete context

Poles, trees, facades, sidewalks, signs and pavement remain spatially related in one three-dimensional scene.

Auditable measurements

The point cloud supports review of height, diameter, tilt, distance and interference using a registered and controlled data source.

Comparable updates

New campaigns can repeat corridors to identify changes, removed assets, vegetation growth or road modifications.

Dashify SLAM

Mobile SLAM and 3D LiDAR mapping for streets, avenues, poles, luminaire arms, urban trees, facades and georeferenced asset inventories.

Six survey scenarios

Dashify combines vehicle and handheld capture across different environments.

Our operation combines vehicle speed, 360-degree coverage and handheld mobility to document extensive corridors and areas a car cannot enter.

Vehicle mobile mapping

Vehicle mobile mapping

Our team uses an integrated vehicle system to survey large infrastructure areas with a continuous trajectory and synchronized imagery and point clouds.

LiDAR + SLAM + GNSS + 360 imagery
Streets and neighborhoods

Streets and neighborhoods

The survey documents carriageways, gutters, sidewalks, access points, facades, visible utilities and street furniture in residential and commercial corridors.

Road geometry, sidewalks and urban frontages
Avenues and main corridors

Avenues and main corridors

The capture covers multiple lanes, medians, intersections, signals, shelters, drainage and lighting within one three-dimensional reference.

Wide corridors and connected assets
Urban forestry

Urban forestry

Processing records location, height, apparent diameter, canopy volume and proximity among trees, poles, facades, circulation routes and overhead networks.

Tree inventory and interference analysis
Poles, arms and luminaires

Poles, arms and luminaires

Technical extraction delivers position, height, tilt, arm length and orientation, plus distances among assets, canopy, roadway and buildings.

Public lighting and vertical infrastructure
Handheld SLAM and restricted areas

Handheld SLAM and restricted areas

Our team completes the survey in plazas, passages, stairs, interiors, alleys and covered areas using a handheld scanner or mapping backpack.

Useful geometry for engineering and inventories

Dimensions and spatial relationships calculated without revisiting every asset.

The point cloud preserves the scene's three-dimensional shape. After processing and control, it can support measurements, records, designs, inspections and maintenance decisions.

Poles and columns

Position, height, verticality, diameter and clearances.

Arms and luminaires

Length, projection, elevation and spatial orientation.

Trees and canopies

Trunk, height, canopy extent and interference.

Roadways and sidewalks

Edges, widths, level changes, ramps and corridor sections.

Signs and traffic signals

Location, height, orientation and relationship to the road.

Facades and envelopes

Planes, distances, apparent volumes and urban envelope.

Dashify defines and documents tolerances, calibration, acquisition conditions, control points and validation methods according to each project's required accuracy.

Controlled technical workflow

From the field route to an inventory ready for decisions.

Dashify conducts planning, acquisition, processing and control under one quality framework, with a methodology tied to the contracted products.

  1. 01

    Project scope and classes

    Our team defines corridors, assets, attributes, coordinate systems, tolerances and delivery formats.

  2. 02

    Calibration and control

    Sensors, synchronization, control points, control trajectories and acceptance criteria are verified before and during execution.

  3. 03

    Vehicle and handheld capture

    Routes are surveyed with controlled coverage, including handheld capture in areas hidden from or inaccessible to the vehicle.

  4. 04

    Trajectory and point-cloud adjustment

    Observations are combined to correct drift, register passes, georeference data and remove survey noise.

  5. 05

    Asset classification and extraction

    Ground, vegetation, buildings and objects are classified to generate records and measurements according to the contracted scope.

  6. 06

    Validation and publishing

    Delivery includes sample control, quality documentation, 3D data, GIS layers, inventories and reports.

Data products

Deliverables prepared for engineering, GIS and asset operations.

Delivery is structured around the contracted application, combining point clouds, inventories, models and reports with formats and levels of detail defined in scope.

3D point cloud

Registered, georeferenced and organized data in formats such as LAS, LAZ or E57 according to project requirements.

GIS layers

Points, lines and polygons with attributes in GeoPackage, SHP, GeoJSON or an equivalent integration.

Asset inventory

Records for poles, luminaires, trees, signs, signals and other elements with position and attributes.

3D model and corridor

Sections, profiles, meshes or simplified models for analysis, design, visualization and digital twins.

Quality report

Methodology, equipment, controls, coverage, limitations, samples and consistency indicators.

Temporal comparison

Repeated campaigns supporting change detection, vegetation growth analysis and record updates.

Technical execution and control

Dashify conducts every survey with measurable acceptance criteria.

Dashify's team plans routes, defines classes and tolerances, performs vehicle and handheld capture, controls coverage and accuracy, processes point clouds, and delivers GIS-ready integrations. Clients receive a complete, documented and scalable service.

Questions about SLAM and LiDAR

Documented technical criteria for every mobile 3D survey.

Clear information about the technology, positioning, accuracy, handheld capture and data products delivered by Dashify.

SLAM means simultaneous localization and mapping. The algorithm estimates the sensor trajectory while building and registering a map of the observed environment. It can maintain continuity when GNSS varies, provided there is sufficient geometry and the survey follows an appropriate methodology.
