Jensen (2018): Small Unmanned Aerial Systems (sUAS) for environmental remote sensing: challenges and opportunities revisited, GIScience & Remote Sensing, DOI: 10.1080/15481603.2018.1510088https://hdl.handle.net/1805/17419Hardin and Jensen (2011) presented six challenges to using small Unmanned Aerial Systems (sUAS) for environmental remote sensing: challenge of the hostile flying environment, challenge of power, challenge of available sensors, challenge of payload weight, challenge of data analysis, and challenge of regulation. Eight years later we revisit each of the challenges in the context of the current sUAS environment. We conclude that technological advances made in the interim (as applied to environmental remote sensing) have either (1) improved practitioner ability to respond to a challenge or (2) decreased the magnitude of the challenge itself. However, relatively short flight time remains a primary challenge to using sUAS in environmental remote sensing.en-USsUASsUAS challengessUAS powersUAS payloadsUAS regulationsSmall Unmanned Aerial Systems (sUAS)environmental remote sensingArticle10.1080/15481603.2018.1510088
