    Sharper Shape has used SimActive software’s distributed processing capabilities to complete utility corridor base maps in Montreal, Canada. In 2022, more than eight million images were collected in SimActive’s Correlator3D software to generate orthomosaics and colorized point clouds.

    Correlator3D, hosted on an Amazon cloud environment, enabled quick processing of thousands of images per day over a network of virtual machines. The resulting map products covered more than 34,000 miles of utility corridor and were imported into Sharper Shape’s artificial intelligence (AI) tools to extract infrastructure information.

    “The quantity of data that we capture to feed our AI tools for utility infrastructure deliverables is incredible and comes from various geographical locations at the same time,” said Petri Rauhakallio, vice president of business development at Sharper Shape. “Correlator3D allows our teams to easily import and process massive amounts of imagery for use in our digital twin production.”

    SimActive Inc., a developer of photogrammetry software, has integrated its Correlator3D product into lidar systems for drones developed by Lidar USA.

    Possible configurations include two side-by-side cameras that allow matching the footprint of the lidar sensor, a particularly useful setup for corridor mapping.

    SimActive’s Correlator3D software is used for automatically registering the imagery with the lidar data. Once a perfect alignment has been achieved, the point clouds are colorized using the photos.

    “The ability to directly use lidar as control for adjusting image positions really is a unique feature,” said Jeff Fagerman, CEO at Lidar USA. “Correlator3D allows our clients to quickly combine lidar with data from multi-camera systems and produce high-quality outputs.”

    Correlator3D software is a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including drones. Correlator3D performs aerial triangulation and produces dense digital surface models, digital terrain models, point clouds, orthomosaics, 3D models and vectorized 3D features.

    Powered by GPU technology and multi-core CPUs, Correlator3D’s processing speed supports rapid production of large datasets.

    Lidar USA, also known as Fagerman Technologies, is a family owned business just outside of Huntsville, Alabama. Lidar USA specializes in laser scanning, photogrammetry, instrumentation and all things geomatics.

    SimActive’s Correlator3D software is being used by by Dutch company NEO B.V. to assess solar potential in multiple cities. Digital surface models (DSMs) are generated from WorldView and GeoEye satellite stereo images and serve to calculate solar panel capacity.

    According to SimActive, DSMs covering hundreds of square kilometres are quickly generated by the software. Key metrics to estimate solar potential are then derived, including roof orientation, pitch and shaded areas.

    “We have been impressed by the quality of SimActive’s DSMs, especially considering the limited spatial resolution of the imagery”, said Rob Beck, managing director at NEO B.V. “Another definite advantage of Correlator3D is the simplicity of the workflow, making it easy to use by our team.”

    SimActive’s Correlator3D software is a patented, end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including UAVs.

    SimActive Inc., a developer of photogrammetry software, announces that its Correlator3D software has been used by Air Data Solutions (ADS) in Florida to determine financial assistance following Hurricane Dorian.

    Aerial imagery was collected before the storm for pre-hurricane assessment and after for damage analysis.

    A Phase One 100MP aerial camera owned by ADS was flown to gather high-resolution images of the affected areas. The data was then processed by SimActive software to create mosaics of orthophotos.

    The resulting geospatial data helped government authorities to calculate recovery aid funds.

    “We have been impressed by the accuracy and speed of Correlator3D to support such a time-critical mission,” said Don Cummins, President of ADS. “Combined with a high-end aerial sensor, SimActive provides the best tool for emergency response.”

    Air Data Solutions is an aerial, terrestrial, and aquatic data collection and modeling company.

  • SimActive software used with eBee X for shoreline mapping

    SimActive Inc., a developer of photogrammetry software, announced that Correlator3D is being used for mapping projects in Brittany, France, by Altimedias.

    An eBee X equipped with senseFly S.O.D.A. 3D camera is flown along the shoreline to produce high-resolution true orthomosaics and 3D models.

    “The quality of outputs from Correlator3D is exceptional and the mosaic renders the vivid colours of the Pink Granite Coast,” said Didier Wasselin, COO at Altimedias, which specializes in drone data collection and processing. “Such results are very useful for heritage conservation and decision making by local authorities.”

    “The combination of SimActive software and senseFly eBee Plus X is an ideal combination, due to the accurate RTK/PPK and optimized aerial triangulation,” said Francois Gervaix, technical advisor at SimActive. “The S.O.D.A. oblique imagery leads to outstanding 3D textured models.”

  • SimActive software speeds large-scale photogrammetry project

    Photogrammetry software Correlator3D was used for a large-scale project by First Base Solutions, announced software developer SimActive Inc.

    The software allowed the processing of 50,000 large-format images at 200 megapixels, collected at a 10-centimeter resolution, on a single standard PC, the company added.

    The size on disk for each image was 765 MB, for a total of 40 terabytes of raw data. Aerial triangulation was performed and digital surface models (DSMs), digital terrain models (DTMs) and orthomosaics were created, leading to more than 100 terabytes of output.

    “We are impressed by the software speed and capabilities on large datasets,” said Brian Leggat, project supervisor of First Base Solutions. “Another advantage is SimActive’s support to quickly help us during our projects.”

    First Base has been a user of the software for more than 10 years.

    SimActive Inc., a developer of photogrammetry software, has enabled the first government drone mapping project in South Korea.

    Asia Aero Survey (AAS), a SimActive regional partner, used Correlator3D for the public survey delivered to the Korean National Geographic Information Institute (NGII) and the Korean Association of Spatial Information, Surveying & Mapping.

    While such projects were previously conducted using manned aircraft, a drone was preferred because of the difficulty in accessing the area of interest through traditional aerial and ground surveying methods.

    The NGII officially published guidelines for public surveying and mapping with drones in March 2018, with the AAS project being the first delivered and accepted as adhering to the new guidelines.

    AAS is also deploying UAV solutions with hyperspectral and lidar for other projects in conjunction with SimActive software.
