Briefly describe why/how in the text box below. 71% Likely or Very Likely • Very Likely • Likely • Unsure • Unlikely • Very Unlikely
    • Coordination in the Future Vegetation Mapping and Measurement using LiDAR Project Survey LiDAR Spatial Coordination Method and Applications INDUSTRY SURVEYMotivations Cognition in the Future Response Diversity by TOBY CLEWETT Barriers Feedback on this question was very strong, with 87% of respondents describing barriers that may exist to effectively utilise LiDAR derived maps, mapping products or GIS analyses in their work
    • Coordination in the Future Vegetation Mapping and Measurement using LiDAR Project Survey LiDAR Spatial Coordination Method and Applications INDUSTRY SURVEYMotivations Cognition in the Future Response Diversity by TOBY CLEWETT Barriers Knowledge Systems Cost “Time to barrier. When LIDAR data is purchased, or licensed, “In terms of utilising LiDAR derived Computing power.” “Cost is ado so - do the processing. maps for the purpose of riparian modelling, there is a bit of a knowledge/resource gap the full range of analysis products are seldom budgeted for by “Appropriate hardware to it. Often it is volumes of data” on project that purchasedmanage large necessary to wait for thehow to extract and utilise the necessary information from LiDAR to provide valuable a different product before the money another project to require inputs into other environmental models.” can be found. This approach ultimately wastes both time and money.”
