Specialized experience in ground-based stationary or mobile laser scanning or FAA compliant UAS surveys
As a technology-motivated company comprised of innovative professionals, Arc Surveying & Mapping, Inc. has always been the leader. The object of Arc Surveying & Mapping, Inc. use of technology is to provide more data, more accurately and to reduce labor costs while enhancing safety in the process. Whereas in the 1990’s Arc Surveying & Mapping, Inc. crews rappelled down steep rock slopes colleting conventional xyz data points at 50 or 100 ft. line spacing, today we survey entire surfaces in a matter of minutes, laser scanning from static positions, from all-terrain vehicles, from survey trucks, vessel mounted surveys and recently collecting topographic data from unmanned aircraft. Arc Surveying & Mapping, Inc. is producing maps, models, videos and CADD files in amazing detail. Arc Surveying & Mapping, Inc. ability to laser scan shallow water canals and stream shorelines and structures from a Jon boat has provided the Department of Transportation with survey data under and around bridges never before available at an affordable cost.
Arc Surveying & Mapping has three drones (UAS) and a FAA Certified UAS pilot/Florida Professional Registered Surveyor and Mapper. It is anticipated that as a result of recent tests by Arc comparing conventionally collected survey data to data acquired by our UAS, Arc Surveying & Mapping, Inc. will be evaluating the cost/benefit ratios and procedures required to assure compliance with local, state and federal regulations. We look forward to adding another technology to our roster and are assured this system will assist in our goal of providing more visualization and precise topographic construction data to our clients.
Comprehensive use of HYPACK for acquisition and processing of dual frequency single-beam fathometer data, identifying bathymetry based on both frequencies
The company’s single beam dual-frequency capabilities include an in-house system consisting of a Knudsen Model 320M survey grade Echo Souder. This system is configured with a dual frequency transducer operating at 200 kHz and/or 28 kHz frequencies. Arc Surveying & Mapping, Inc. hydrographers have made comparisons in shallow water depths to the standards defined within the U.S. Army Corps of Engineers Hydrographic Manual with special attention to the dimensions and configuration of Lead Line Sounding Devices and the requirement to utilize such in the event of detecting unconsolidated or “fluff” bottom conditions. Processing of dual frequency sounding data is performed in HYPACK’s single beam editor module which allows for the inspection and editing of dual frequency sounding data. This module gives our hydrographers the ability to analyze each frequency separately, or together, in order to identify the bottom returns recorded and export individually for mapping and volume computations. Arc Surveying & Mapping, Inc. introduced dual frequency sounding to the Jacksonville District over twenty years ago, recognizing the disparity in dredging quantities due to the presence of both suspended and semi-consolidated sediments in estuary channel areas. Arc Surveying & Mapping, Inc., as is the ACOE Research and Development Center (ERDC), is experimenting with new survey techniques to establish nautical depths measuring viscosity to better define the interface of “Fluff” versus consolidated sediment.
