KOMPSAT-3

KOMPSAT-3 is a Korean satellite operated by SI Imaging Services (SIIS). It provides enhanced 50 cm panchromatic and 2 m multispectral resolution imagery across visible and near-infrared bands. With a swath width of 16 km and single-pass stereo collection capability, KOMPSAT-3 is well-suited for government projects, large-area mapping, oil and gas operations, and frequent monitoring. Its 14-bit data depth helps retain image detail in shadowed areas and supports consistent colour representation.

"Our gold exploration project needed some special attention being located on a weather beaten island with lots of cloud, snow, fog and other items to consider. Pacific Geomatics understood this and provided a competent service and modern support tailored to our needs resulting in satellite images we could use quickly and effectively. Products were tasked with a constant view to weather windows and always delivered on time. New Found Gold would highly recommend Pacific Geomatics for mineral exploration needs and the wide range of products they provide."

"PacGeo makes locating and purchasing satellite imagery easy. Their online search tool and ordering process is intuitive and the end product is excellent quality. We have used them for multiple years to order high resolution imagery for disturbance mapping at a fraction of the cost of airborne surveys. We would recommend them to other exploration companies as it is the easiest and fastest way to get high resolution imagery for your project."

"The service provided by PacGeo was great. From the first time I contacted them to request quotes, through the purchasing and delivery of data, they were always responsive and helpful. One of the things that I liked the most was that they did not try to push any particular type of data, but rather worked with me to determine what was best for my needs, even when it meant going to providers to get solutions that were not off-the-shelf. Even after the data was delivered and we had technical issues with storage on our end, John made sure it was redelivered so our project could move forward. I would work with them again without hesitation."
