    Verified photomontages for UNESCO World Heritage sites achieves accuracy with Spectra Geospatial SP80

    Verified photomontage is an important planning tool to envision how proposed surrounding development plans would affect UNESCO World Heritage sites. Verified photomontage demands the best accuracy for the best visualization to determine what a development may look like to a person standing at the photographic viewpoint.

    For MS Environmental (MSE), selected to provide verified photomontage for multiple UNESCO World Heritage sites, including in the UK Royal Botanical Gardens at Kew and the City of Bath, the Spectra Geospatial SP80 GNSS receiver enabled the highest quality visualization.

    “The one-centimeter accuracy delivered by the SP80 is essential,” said Mike Spence, a verified photomontage specialist and founder of MSE. “The highest level of accuracy in the relationship between the actual camera location and the 3D model camera gives confidence in the visualization. In addition, The SP80 offers both simplicity and a robust design though it’s taken a few knocks over the years, it gives us the confidence we can use the equipment anywhere in the world and get the best results.”

    At Kew Gardens, MSE was commissioned to produce accurate visualizations of views from within the UNESCO World Heritage Site. There was concern about development proposals for tall tower blocks in west London and how these might affect historic views from Kew Gardens.

    The work culminated in a public inquiry, where evidence was presented that showed how views would change as a result of the proposed development. “Without the level of accuracy provided by the SP80 together with a transparent technical methodology it would have been unclear precisely how these historic views would change,” Mike Spence said.

    At the UNESCO World Heritage City of Bath, the Bath and North East Somerset Council commissioned MSE to produce technical photography from strategic views around the World Heritage City to show how development proposals would affect strategic views across the city.

  • SP80 under cover in Chile’s rainforests

    In the temperate rainforest of the Los Lagos region of Southern Chile, where rainfall annually exceeds 1,500 millimeters and two-thirds of the days are rainy, the dense forest canopy poses a huge challenge for GNSS receivers.

    Motivazion, a survey firm based in Puerto Montt, just below the rainforests, makes its living surveying in the rugged terrain under the densely canopied forest. Motivazion works primarily for hydropower development companies, surveying contours, cross sections and longitudinal profiles, as well as staking out proposed facilities. To ensure it was using the best GNSS receivers for the conditions, Motivazion conducted field tests of several sets of equipment this summer. 

    Motivazion owner Jorge Mesias said he typically uses a combination of total stations and GNSS receivers for his work. “If understory performance could be improved, efficiency would increase dramatically and reduce the need for using the more time-consuming total station,” Mesias said.

    A light rain fell at all times during the two-day test. The test routine consisted of surveying a total of 21 points in two days. Results were compared to points established by a total station. 

    Base stations were set up in a small area cleared for the purpose, and the rovers moved from point to point under the canopy. Spectra Precision’s SP80 achieved fixed solutions in less than three minutes 95 percent of the time.

    “The SP80 achieved remarkable results,” concluded Mesias. Geocom S.A., Spectra Precision’s dealer in Chile, provided the SP80 and technical support.
