Quantum Spatial is at the Alaska Survey and Mapping Conference in Anchorage. We are excited to share some of our recent work in remote sensing acquisition and analytics, including thermal infrared imaging, precise point positioning acquisition, topobathy LiDAR, and eGIS solutions. Additionally we look forward to meeting new people, reuniting with old friends, and exchanging ideas with other attendees.
Come visit us at Booth 11 and be sure to attend our presentations on Friday morning and afternoon.
Title: Our Insatiable Quest for Higher Accuracy in the Middle of Nowhere
Presenter: Evon Silvia
Airborne mapping surveys have traditionally required static GNSS/GPS control proximate to the project area in order to meet established mapping accuracy specifications. However, access to remote, rugged, or heavily forested areas can make ground surveys prohibitively expensive, particularly when they must be coordinated to coincide with the airborne acquisition. The use of Precise Point Positioning (PPP) as an aircraft trajectory processing technique has evolved in recent years as a viable alternative to the current standard of differential GNSS processing. Quantum Spatial has extensive experience using PPP during our Alaska operations where establishing static base stations in remote areas prior to the flight was not feasible. This presentation will explore the accuracies associated with PPP processing and the considerations for applying these techniques for various applications.

Overview of Airborne Thermal Infrared Remote Sensing Applications in Alaska
Presenter: Mousa Diabat
Thermal infrared (TIR) imagery is an effective method for mapping features and processes based on emitted thermal infrared radiation at wavelengths that are not visible to the human eye. Airborne TIR has been used in Alaska for a wide range of applications and the utilization of this technology will continue to increase due to the development of the sensors for deployment on unmanned air systems (UAS) and the growing number of applications related to energy efficiency and climate change research. However, TIR imagery can also be difficult to interpret and process because of changing atmospheric conditions and the thermal properties of the features of interest. In this presentation we will explore the technology and considerations for data acquisition. We will provide examples of recent applications in Alaska including mapping thermal habitat for salmon, fire mapping, animal detection, building energy efficiency, and other relevant projects.
