The firm is a global leader in tablet-based data acquisition technology and has deployed state-of-the-art tablets to all field crews in North America. The tablet systems provides advantages for every type of fieldwork, with benefits of increased speed and productivity in data collection, transmittal and management across the project cycle. For office operations our technicians use integrated CAD workstations equipped with the latest software, including AutoCAD, MicroStation, GEOPAK, BlueSky software, and PLS-CADD.
Mobile Mapping System
SAM uses two complete Teledyne Optech Lynx® Mobile Mapper systems as part of its broad inventory of advanced surveying and mapping technologies. The non-invasive, state-of-the-art Lynx Mobile Mapping system is ideal for civil engineering firms or government agencies managing rail surveying, road surveying, pipeline surveying, waterway, electric power line survey services and design-build projects. It incorporates the most advanced LiDAR (Light Detection and Ranging) sensors, digital cameras and a GPS navigation system to quickly and accurately collect survey-quality point data for corridor projects throughout North America.
Airborne LiDAR System
SAM owns and operates state-of-the-art Trimble and RIEGL Laser Scanners that can be deployed from helicopter, fixed-wing aircraft, or Unmanned Aerial Systems (UAS). These are the most advanced LiDAR scanning systems on the market and have impressive specifications, including a very high rate of data capture, extremely dense data capture (or point cloud), a 45-60 degree field-of-view, and and up to 80 megapixel medium-format digital frame cameras.
Digital Photogrammetry and LiDAR Aerial Mapping
SAM's fully digital Photogrammetry Department utilizes state-of-the-art workstations to develop Digital Terrain Models (DTM), Planimetric Mapping, and Digital Orthophotography. SAM's services include comprehensive LiDAR acquisition and data processing solutions. Using multiple data processing software systems, we tailor our LiDAR data processing to the specific need of clients. SAM provides aerial mapping services across North America to a wide variety of industries including infrastructure, pipelines, electric transmission, environmental, and rail.
Unmanned Aerial Systems (UAS)
We utilize multiple professional-grade UAS platforms, including both rotary and fixed-wind aircraft, to perform data acquisition tasks to meet a wide range of client needs in different market sectors. Our aerial platforms carry a variety of industry leading data imaging systems to capture high resolution photos, video, thermal images, LiDAR images, and other data types.
Geographic Information System (GIS) Services
As an Esri® Partner Network Silver Member, SAM provides complete turnkey solutions and custom purpose-driven applications developed for project planning, management, and implementation services. GIS application developers, analysts, and technicians utilize the latest in high-speed computational workstations, combined with high-resolution displays capable of 3-D visualization, and integrated with a high-capacity network storage system. All data products generated by the surveying, aerial mapping, SUE and utility coordination service divisions can be delivered in a variety of GIS and CAD formats. SAM also utilizes 3-GIS® software that enables a multi-user, browser-based interface for the management of GIS data by credentialed users, whether from the office, in the field, or on-the-go.
Subsurface Utility Engineering (SUE)
SAM uses the latest Subsurface Utility Engineering technologies: radio frequency, acoustic, sonic magnetic sensing, ground penetrating radar (GPR), subsurface LiDAR scanning, and non-destructive vacuum excavation equipment. These tools allow SAM’s SUE technicians to quickly and reliably designate, locate and accurately map underground utilities, as well as assist clients in utility coordination.
Terrestrial Laser Scanning
SAM provides experienced High Definition Surveying (HDS) data acquisition, project control, filtered data and complete schematic drawings and 3-D models for a variety of terrestrial laser scanning applications, including civil, mechanical, electrical, architectural, and archaeological. These services are performed using Trimble and Leica laser scanners for high-density data collection in the field. Each of these scanners can deliver highly-accurate data for different defined project parameters. These are backed by high-speed computational workstations connected to high-resolution displays and integrated with high-capacity network storage systems for data processing operations.
SAM-PRO™ and 360-Degree Video
SAM-PRO is software we've developed to provide access to spatially referenced image data through a user-friendly interactive interface. The GIS-based system delivers photos, video, and LiDAR images through a stand-alone application that operates in an Esri® software environment. The system can also utilize video from our proprietary camera array to deliver full 360-degree panoramic video in HD quality. For clients across several market sectors and project types, SAM-Pro has proven to be a very effective tool for navigating through large amounts of imagery and video data. Combined with SAM’s 360-degree video acquisition capabilities, we offer this exceptional new option to help manage your project assets.
Mobile Device Apps
SAM has developed its own proprietary mobile apps to support various client project information management needs. These apps are available for iOS and Android devices through their respective app stores. They enable SAM clients using mobile devices to access mobile forms and submit data pertinent to their projects. Built using an industry leading proprietary platform, they offer a cloud-based, paperless approach to field data collection, allowing our clients to utilize a workflow that maximizes speed, efficiency, accessibility of their project forms. SAM can customize mobile forms to meet our clients' unique project needs and all submitted data is stored in our own cloud with secure client access. With SAM mobile apps your project field data can easily be submitted and accessed using mobile devices you're already familiar with.
