data - What to consider when hiring aerial LiDAR survey?



My organization is considering hiring a company to capture new LiDAR data to help with current stormwater issues that we are currently experiencing. I am a GIS analyst that has been assigned with this task.


Our current quote is for roughly 70 square km and the project deliverables will include:




  • 1m resolution orthophoto TIFF imagery.

  • 50cm resolution orthophoto TIFF imagery.

  • Tiled 11cm resolution orthophoto TIFF imagery - each image delivered in ATS sections.

  • LiDAR data collected with approximate 7 points per sq meter.

  • Raster bare earth DEM produced from the LiDAR data. Two files will be delivered:

    • 1 - 50cm grid spacing.

    • 1 - 1m grid spacing.




  • 6 new survey checkpoints.


We have been quoted roughly $30000 CAD (canadian dollars).



  1. Is cost of new LiDAR data reasonable for deliverables provided?

  2. What else should be considered when hiring aerial LiDAR survey?


Any feedback would be great. I have never had the luxury of being included in data purchases so this is all new to me.
