  • 3D Geologic Map of Moab and Surrounding Area (Redesign)

    This is a redesign and 3D rendering of “Geologic map of the Moab and eastern part of the San Rafael Desert 30’ x 60’ quadrangles, Grand and Emery Counties, Utah, and Mesa County, Colorado” by Hellmut H. Doelling. My source data was the linked map PDF, as well as separately downloaded copies of digitized versions of ...
  • Satellite Imagery: Arizona, Oct. 2020

    This image was prepared from all or parts of 19 different Landsat-8 scenes captured in October of 2020 (from 5 different orbital paths). I used QGIS for the initial sizing and alignment of the data layers, and did the rest of the work (merging, composing to RGB, color + light correction, seamline feathering, etc.) i...
  • Geologic Map of Nevada (Digitally Restored)

    This is a restoration of a scanned copy of Geologic map of Nevada 1978, by John H. Stewart and John E. Carlson, produced by the United States Geological Survey in cooperation with the Nevada Bureau of Mines and Geology.
  • Geologic Map of New Mexico (Reprint)

    This is just a slight design tweak and touchup of the excellent Geologic Map of New Mexico, published by the New Mexico Bureau of Geology and Mineral Resources, 2003, Scale 1:500,000. I fixed a few graphical glitches in the original, redid everything outside the state border, and tweaked the typography - keeping the...
  • Geologic Map of Arizona (Digitally Restored)

    This is a design tweak and touchup of a scanned copy of Geologic map of Arizona ca. 1988, by Reynolds, S.J, produced by the Arizona Geological Survey in cooperation with the USGS. I georeferenced the scan and projected it to WGS84 UTM12N.
  • Satellite Imagery: Utah, Sept. 2018

    This image was prepared from all or parts of 18 different Landsat-8 scenes mostly captured in September of 2018 (from 4 different orbital paths). I used QGIS for the initial sizing and alignment of the data layers, and did the rest of the work (merging, composing to RGB, color + light correction, seamline feathering...
  • Satellite Imagery: New Mexico, Fall 2020

    This image was prepared from all or parts of 23 different Landsat-8 scenes captured between September 27 and October 10 of 2020 (from 5 different orbital paths). I used QGIS for the initial sizing and alignment of the data layers, and did the rest of the work (merging, composing to RGB, color + light correction, sea...
  • Satellite Imagery: Nevada, Summer of 2018

    This image was prepared from all or parts of 21 different Landsat-8 scenes captured in June, July, and August of 2018 (from 5 different orbital paths). I used QGIS for the initial sizing and alignment of the data layers, and did the rest of the work (merging, composing to RGB, color + light correction, seamline feat...
  • Geologic Map of Utah (Digitally Restored)

    This is a restoration of a scanned copy of Geologic map of Utah 1980, by Lehi F Lintze, produced by the Utah Geological and Mineral Survey in 1980.
  • Satellite Imagery: Eswatini

    This image contains parts of 2 different Landsat-8 scenes captured in December of 2017. It shows the entirety of the African nation of Eswatini (formerly Swaziland) in Landsat-8’s full 15m pansharpened resolution.
  • Satellite Imagery: Baja California Sur

    This image contains parts of 12 different Landsat-8 scenes captured in the winter of 2018 & 2019. It shows the entirety of the Mexican State of Baja California Sur in Landsat-8’s full 15m pansharpened resolution. The ocean was filled in with a solid color during post-processing.
  • Satellite Imagery: Mojave Desert

    This huge image was prepared from all or parts of 12 different Landsat-8 scenes captured in September of 2019 (from 4 different orbital paths). I used QGIS for the initial sizing and alignment of the data layers, and did the rest of the work (merging, composing to RGB, color + light correction, seamline feathering, ...
  • Satellite Imagery: Denali, Alaska

    This was made from 3 different Landsat-8 scenes from July and August of 2017. I used QGIS to prep and trim all of my raster layers, and then used Affinity Photo to merge, compose, and color correct the final image. In these captures, Denali is so snowy and bright in contrast to the grassy green terrain around it, th...
  • Satellite Imagery: Gold Butte National Monument

    This image contains parts of 2 different Landsat-8 scenes captured in July of 2017. It shows Gold Butte National Monument and a large swath of the surrounding region in S. Nevada, NW. Arizona, and SW. Utah. To prepare the relief shaded version, I used Blender with the Blender GIS plugin to prepare a 3d mesh from 10m...
