Cannot import GE KML/KMZ

Can't seem to import a KML or KMZ exported by Google Earth. A number of other apps import this same file, but caltopo gives me "Sorry, no importable features were found.". Seems to be somehow specific to this file, I can import other KML/KMZ files from GE.

    We'll take a look at the file and get back with you!

    Somehow this fell off the queue and was totally missed. I'm now working on it! So sorry.

    I'm not the original submitter but have been experiencing the same problem
    with kmz/kml files. I have several that I can give you or suggest if you

    On the original file the issue could be the custom style IDs, we can parse custom styles on the object itself but run into problems when the styles are listed as they are in this example file. There are also some characters that may be causing issues within the item names (URLs, etc). This is likely why you're running into import issues. Feel free to send any other files over, but KML is a huge file spec and there are features of KML not supported by CalTopo.

    Cool. I figured it was probably formatting problems in the file itself that
    may have changed since last year. The files I am sending you are KMZ files
    of active Fire Perimeters that I want to include in my map. What I expected
    to see was something like when I download the KMZ for Colorado Wilderness
    areas where I can select any individual wilderness area that I want to
    include, but in this case for specific fires. Then hopefully as the
    perimeter changes it would update automagically on my map.

    I get the files from

    The GEOMac, activefireperimeters, and for reference the Colorado
    Wildernesses files are attached to this email. Note that there is a kml and
    kmz version of the activefireperimeters for comparison.

    Maybe there is a way to just make it a toggle layer like the active fire
    layer already in the app.

    Thanks for such a great product and responsive help!! You guys are doing
    great work!

    Hi Ben, I have found a workaround. A other app was able to import it, then
    I exported to GPX and imported in Caltopo. You can close this request.

    Here is the other thread I mentioned a few minutes ago.

    In your closing email you mentioned some issues with importing KML files
    because of the extensive standard. I understand that dilemma and can live
    with it. I think that what I am looking for though is in the KMZ files.

    Maybe it would be easier to include the Active Fire Perimeters as an
    included layer in the SARTopo menu along side the Active Fires layer?

    Did some investigating, as you state the Colorado Wilderness areas imports totally fine, the Active Fires layer doesn't. I'm going to have a developer look at this since both use style ID (KMZ files are just KML files zipped). I see a null pointer exception when I go to import the active fire layers but not sure why that is occurring. We'll do a little more digging.

    Hey guys,
    We found the bug in the KML importer. We're deploying a fix likely later tonight and you should see this issue resolve in the next couple days.

    With that fix all these files EXCEPT the Fire Activity file seemed to work. It looks like the fire activity file has a white space between the latitude and longitude which is not allowed in the KML spec. You could probably reach out to the publisher of that file and let them know its not in alignment with the spec, they may be willing to fix it...

    Thanks for working with us to fix this!
