Raster Survey – The Cloud and Imagery Use

Here are a couple questions that some of our Imagery Team members were curious about.  Please feel free to use the “Comments” section to post your answers.  Thank you!

1) Do you use The Cloud in your imagery storage solution?

  1. Yes, for years. (Who doesn’t?)
  2. Planning to. (We are technology savvy.)
  3. As long as we have the money. (We are technology savvy, but we are on a budget.)
  4. No, prefer storing locally – security issues.
  5. No, what the heck is The Cloud?

2) What do you use imagery for?  (List all, in order of importance)

  1. Feature extraction
  2. Object-oriented classification
  3. Orthophoto production
  4. Quantitative analysis
  5. Pixel-based classification
  6. Visualization
  7. Other

    i like the esri basemap(s) for imagery. however we have to maintain internal tiled mapservices “in case the internet goes down”.

    I store my imagery locally but it is backed up at the State GIS clearinghouse so it technically is available in the cloud.

    2. 1,6,4,2,5

    Working for an Esri Distributor I see the following trends with our clients
    - They use cloud imagery for basemaps and then add their own local imagery for areas that they have higher resolution imagery
    - The major imagery format we deal with is ECW (as this is what the imagery providers use) and hence the usage is primarily visualisation and overlay. Slowly there is a move towards more image analysis, but as one of the concerns for imagery is storage space ECW is still a large part of the ongoing GIS landscape here in Western Australia

    Hope this helps,

    We create and serve multiple web applications requiring aerial photography, albeit cached, but why use the cloud when Terrabytes are so easy to come by and becoming so much cheaper.

    4 – except bandwidth issues.
    6, 5, 4, 1, 7

    Q1: No, prefer storing locally – security issues and on a budget
    Q2: Feature extraction, Visualization

    1) 4 maybe 3 also
    2) 4,6, 1

    ‘Cloud’ is a loaded term, which means different things to different people, so for clarity a couple of years back we agreed enterprise wide to not use ‘cloud’ but rather ‘moon’. We see several benefits to moon based imagery storage. All newly acquired imagery is loaded straight onto the moon. It can be seen within 24 hours in any of our offices world wide, so we reduce the risk of duplicate imagery purchases. Security is a concern, other people could have access to the moon, but the reality is most moons are hard to access.

    We’re looking forward to seeing more imagery (and image service) support in the ESRI AGOL moon soon.

      MOON computing!!! I like it.

      But I figure Cloud will still be a very popular word, because its growing vagueness in semantics makes people feel comfortable using/misusing it. Just like DO is always a more popular word than EXECUTE… :)

      Anyway, thanks for the interesting input.

    Q1) 4, reliability, access, budget, security
    Q2) 6, 1

    1) 2. We gave our imagery to the Community Basemaps program, but it was never ingested. We also submitted it to AlaskaMapped.org, but it was never published.

    2) 1, 4, 6
