Mobile Mapping

state-of-the-art, vehicle-mounted System

Martinez Geospatial owns a state-of-the-art, vehicle-mounted Optech Lynx SG1 Mobile Mapper™ system for acquiring high-density, survey-grade three-dimensional point data and digital imagery at highway speeds. This rapid, remote data collection allows potentially dangerous/hazardous locations, such as roadways, railroad corridors, and airport movement areas, to be surveyed quickly, safely, and accurately with minimal expensive and inconvenient traffic control measures.

Martinez Mobile Mapping

Our Mobile Mapping point clouds consist of x, y, z, and intensity values for millions, or more often billions, of points, resulting in a highly-detailed and accurate three-dimensional (3-D) record of the site conditions at the time of the survey. 

The data can also be seamlessly integrated with high-definition static terrestrial laser scanning (HDS), airborne LiDAR, and/or conventional survey data, allowing the point cloud to be referenced to a geographic or local coordinate system and/or vertical datum.

Feature Extraction

We extract the 3-D locations of the visible features from the processed mobile mapping point cloud for creating planimetric or topographic maps. Even 2-D features, such as paint markings, can be collected from the point cloud by using their laser return intensity values. Having a color point cloud can also aid in correctly identifying specific types of materials and underground utility markings.

The high level of detail apparent in a mapping point cloud, combined with the geo-referenced digital imagery, allows for accurate tree classification and sizing, sign inventories, catenary surveys, and bridge clearance measurements to be performed from the office rather than in the field. 

Deliverables

We provide clients with guidance for working directly with the mapping point cloud data or use the data itself to produce a wide variety of customized products in numerous industry-standard formats. Our team works closely with each client to ensure that every deliverable meets the specific needs of the client for that particular project.

Common deliverables include:

  • 2-D and/or 3-D Planimetric / Topographic CADD Drawings
  • 3-D Digital Terrain Models (DTM) / Digital Elevation Models (DEM) / Triangulated Irregular Network Files (TIN)
  • GIS Shapefiles
  • Area and/or Volume Calculations
  • Legal Exhibits
  • Point Clouds (LAS, PTS, LAZ formats)
  • Planimetric / Topographic CADD Drawings
