This data from four Landsat satellites, shows the traditional rectangular patchwork of agricultural fields in the Texas panhandle being overtaken by the signature polka-dotted pattern of center-pivot irrigation. The bright red colors show healthy vegetation due to irrigation in this false-color composite. The data shows reflected light in the near-infrared, red, and green regions of the electromagnetic spectrum. Green and white colors are bare soil, fallow fields, and sparse grasslands. The X shows roads into the town of Dalhart. The final image is a natural color view of Dalhart today.
