This website directs visitors to remote sensing resources to accelerate their implementation of the technology for geologic and environmental applications.
The website Headings (Home, Textbook, Case Histories, Experience, Brooks Range) are at the top of your view or revealed by clicking the 3 short horizontal lines in the upper right corner of your view. The drop-down menus in the Textbook, Case Histories, and Brooks Range sections reveal more pages offering additional resources.
I (James Ellis, the principal of Ellis GeoSpatial) have been implementing remote sensing & GIS for four decades. In April 2020 I published the textbook shown below with the late Floyd Sabins. In addition, I created much free, digital educational material (also shown below) that can be downloaded and supplements the textbook.
Case histories that involved me and span the past 3-1/2 decades are provided at this website. The industry-focused case histories obtained their data from satellite and manned-aircraft. The case histories provide a historic perspective on the maturing of natural resource applications as remote sensing's location accuracy, spatial and spectral resolution, and sensor signal-to-noise markedly improved from the mid 1980s to present.
The widespread use of remote sensing by all sectors has significantly accelerated the past 1/2 decade with the rapid adoption, decreasing costs, and miniaturization of Unmanned Airborne Systems (UAVs or "drones") and sensors. UAV operators still need to understand remote sensing principles, types of available technologies, and limits of technology in order to create accurate, defensible, and useful UAV imagery, DEMs, and maps for their customers. UAV operators can acquire the necessary skills through online learning, attending geospatial courses at local colleges/universities, joining societies and groups (such as Drone U), and by exploringthe resouces provided at this website.
This website also contains a collection of Brooks Range Holocene Glacier publications, images, and maps developed during my graduate school field work between 1977 and 1982. The goal of this collection is to provide curious people easy access to information that can be difficult to find and view for those outside of academia and research agencies - and to inspire new field work and geospatial mapping of Arctic landforms.

Downloadable Case Histories
Remote Sensing Case Histories spanning the past 3-1/2 decades demonstrate how different projects successfully applied satellite and airborne imagery to improve mapping and understanding of features on the Earth's surface. The case histories demonstrate how the energy and minerals industries supported the use of remote sensing since the mid 1980s for mapping, logistics, exploration, and environmental baselines/monitoring.
