We combine publicly available archives with our own aerial imagery to help provide context. https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/003910ec-8707-4d3e-a211-61352545783e/portfolio1.jpg Portfolio - Environmental Assessment Current drone imagery captured by HollerTech reveals how the sediment deposit actively alters stream flow and surrounding terrain. Real-time data like this allows us to assess ongoing environmental impact and guide effective mitigation strategies. https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/491ca69f-d1dd-4473-84e8-45465e78178e/Slope+Analysis+Map.png Portfolio - Environmental Assessment This color-coded photo from our full scale QGIS map highlights slope severity across the watershed, pinpointing high-risk erosion zones. By visualizing terrain gradients, HollerTech identifies areas contributing to sediment buildup and supports data-driven land management decisions. https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/edad3821-fa8e-48ff-b76e-a051154e3ef3/portfolio3.jpg Portfolio - Environmental Assessment High-resolution drone imagery captures a hard-to-reach runoff drain feeding directly into the stream. HollerTech’s aerial perspective helps identify hidden contributors, such as this one. https://www.hollertechwv.com/portfolio/upariver monthly 0.5 2026-05-17 https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/a1444597-94b4-46d6-b477-c8f4be00a885/IMG_3117.JPG https://www.hollertechwv.com/portfolio/catchemall monthly 0.5 2026-05-17 https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/c2d445e2-dc14-4e47-882d-06cbb7c30476/IMG_2977.jpg https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/8f0a5054-057a-4ce4-9bc1-2b29539d5784/IMG_2968.jpg https://images.squarespace-cdn.com/content/v1/67e73104ea18071afd132499/df2e4ce6-c153-4811-b7a8-fadba70e5a90/IMG_2949.jpg
