2017 was an exciting year for Nearview. We hit many firsts including photogrammetric mapping of a 200+ acre gravel and sand mine in freezing wintry conditions, documenting wetland restoration progress at a Superfund Site, and our first large-scale multispectral vegetation survey that processed over 25,000 images. We’ve successfully supported clients by providing accurate and high-resolution map products at low cost and with rapid turnaround. We are already gearing up for a busy 2018, and in the planning stages of a multi-year beach erosion study along the northern New England coast, mapping invasive species and eelgrass for conservation and land trusts, and providing aerial documentation and mapping services for environmental justice groups. Nearview has the experience and expertise to help you safely launch drone operations, all the while respecting privacy, and mitigating cost and risk. This year we plan to scale-up operations, bring on staff, and expand our hardware, software, and technological capabilities. We look forward to talking and working with you in 2018. Drones for Good!

Stefan Claesson was recently certified ‘UAS Mapping Scientist’ by the American Society for Photogrammetry and Remote Sensing (ASPRS). Pleased to be part of a small group of only ten individuals nationwide that have achieved this certification. If you looking to integrate aerial drone survey and mapping into your conservation, engineering, and environmental compliance projects, you can trust Nearview to deliver high-quality geospatial and mapping products you need quickly and at lower cost than any other traditional survey method.
NOAA’s Hydrographic Services Review Panel held its annual meeting earlier this week in Portsmouth, NH. Substructure was there to demonstrate our hydrographic and maritime archaeological survey capability on survey vessel Mintaka. We will be running multibeam demonstrations through next week. If you are interested in coming aboard to survey the Piscataqua River, and see what we can do for you, please contact Carol by email or phone (603-957-1045). Demos will be approximately 2 hours total time.

Liftoff! Nearview has successfully completed an UAS survey for Jacobs Engineering Group in response to a request for a survey demonstration at the New Bedford Superfund Site in New Bedford, Massachusetts. Jacobs is contracted by the U.S. Army Corps of Engineers (USACE) to perform remedial actions at the U.S. Environmental Protection Agency (EPA) managed New Bedford Harbor Superfund Site. These activities include excavation of impacted sediments within the intertidal and subtidal areas of New Bedford Harbor, and require surveying and monitoring to be conducted during remedial actions including pre-excavation, post-excavation and post-backfill activities.

The objective of this survey was to acquire drone-based photogrammetric data over several areas of interest, and to use the resulting point cloud topographic data and aerial imagery to create a variety of engineering data products needed to assess and plan for the ongoing remedial actions. By comparing this data to recently acquired land survey data, Jacobs was able to assess the accuracy, repeatability, and cost effectiveness of UAS photogrammetry for pre- and post-remediated areas.
Stefan Claesson of Nearview, with assistance from Andrew Kelly of Substructure, effectively acquired all photogrammetric data within a single low-tide period, and delivered a variety of survey-grade data products including 3D models, orthomosaics, and topographic point cloud data that exceeded USACE survey and engineering standards and project requirements. Notably, areas that required days to cover with traditional land survey methods, Nearview was able to survey over a period of hours by UAS, and at much greater point density and resolution. Jacobs engineers were able to confirm the accuracy of Nearview UAS survey data through comparisons to the previously acquired land survey data.

The ortho-imagery and resulting topographic data will be used by Jacobs to evaluate project progress, plan further actions, calculate the volume of remediated materials, and document surficial changes over the course of the project. The UAS methods were also noted by Jacobs as being advantageous in mapping the intertidal zone and wetlands, as well as areas inaccessible due to soft sediments and fragile ecosystems.
With its proven techniques and capabilities, Nearview is excited to be able to offer its expertise and services for complex engineering and soil remediation projects.
In addition to our proven aerial-marine survey methods, Nearview and Substructure offer unmatched expertise and survey capability for detection, mapping, and recovery of maritime archaeological resources. Stefan Claesson, founder and CEO of Nearview, has 25 years of experience in maritime archaeology. He is a leader in the fields of submerged prehistoric archaeology, intertidal and waterfront archaeology, shipwreck and submerged aircraft archaeology, military history, and marine GIS. Substructure provides world-class hydrographic survey, commercial diving, and customized marine fabrication services. Our maritime archaeology team has the capability and resources to deploy worldwide, and our survey products exceed IHO Special Order standards. We have a broad range of in-house survey technology including:
- Single beam, side scan, and multibeam sonar
- Sub-bottom profiling

Our commercial diving outfit meets OSHA and USACE diving standards and guidelines. We provide SCUBA as well as Surface-Supplied Diving support. Additionally, we deploy Seatronics ROVs including the Predator II and MK3 equipped with state-of-the-art positioning, sonar, and imaging systems.
Our survey vessels include:
We have an in-house fabrication unit, and can build work platforms and sediment containment units for dredging and underwater archaeological recovery operations to any specifications.

Nearview and Substructure developed survey-grade maps of the waterfront and intertidal zone of this marina using high-resolution aerial photogrammetry and multibeam sonar.
Capturing and developing seamless high-resolution nearshore, foreshore, and backshore topo-bathy digital surface and elevation models in the past has proved extremely challenging. Although NOAA Office for Coastal Management’s coastal LiDAR data sets provide critical elevation data required to produce datum-based shorelines, bathymetric points collected via Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) are spaced fairly wide in comparison to topographic points, and there are often large gaps in areas where there is significant wave action and high turbidity. With the collection of bathymetric point via multibeam sonar at sea by Substructure, and topographic points via small Unmanned Aerial System (UAS) LiDAR and photogrammetry of land by Nearview, we are able to provide continuous, consistent and accurate coverage across the land-water interface. Our methods are particularly well-suited for monitoring of coastal erosion, soil remediation surveys, survey of port and waterfront facilities, and mapping of nearshore, intertidal, and wetland habitats. Our aerial-marine survey approach provides an unparalleled level of detail of current and existing shoreline conditions, and can be used repetitively for detailed change analysis. Please contact us to discuss your project and mapping needs.

Hi everyone! The month of February is “Art ‘Round Town” gallery walk in Portsmouth, New Hampshire. Through the month of February, Ceres Street Bakery and Cafe (Portsmouth, New Hampshire) will be featuring my aerial photography on their walls. My goal is simple – create artwork and images that change the way we view and appreciate our natural and cultural landscapes. Aerial drone photography has fundamentally changed the way I see the world, particularly views of inaccessible and inhospitable coastal environments and places such as wetlands, marshes, and bogs. The unappreciated beauty of these places can often only be captured through low-altitude, high-resolution aerial photography. The exhibit will include framed and canvas wrapped images. If you cannot make it to the exhibit, but would like to buy a print, please contact me and I’ll get back to you with pricing and options.
