How Prefetch feature works ??

Posted by Sonia Kouassi Eba Kaudjhis on April 10, 2012 at 7:32pm

I would like to know how prefetch works ? I click prefetch button hold atl click on maps do download this maps after i don't know how can i reload this map downloaded when i don't have internet connection because prefetch settings permit to cache map data so you don't need Internet access at the field 

I would like to known how to load my cache maps on fields where this is not internet connection on APM mega Planner

Do you you know how can i do that ?

Second question about scripting python how can i test it on APM megaplanner This kind of script is used for test  (in simulation mode ) only or for it can used it in fligth mode ?

Thanks u for your answers

    Michael,

    I want to prefetch a very large are up to zoom level 18, and then some time later fetch a smaller subset of that area up to max zoom. Does MP replace what was already there or just fill in the gaps in the higher zoom levels?

    Also, if I keep adding areas I don't already have, will the cache just keep growing infinitely or will MP reach a limit at some point? Or would it be better to keep separate cache folders for different locations and swap in the one I need at the time?

    Thanks

    1. prefetch just downloads the images to a cache. you just need to hold down alt and draw a box on the map, then click prefetch.

    2. you can use python scripting in real flight, but you need a very reliable telemetry link. as it overrides your rc transmitter.

    use with CAUTION
