Modularization of export code #341

Re: #298 just starting here!

This is looking really good but there are a lot of warnings in the log, and a couple of the steps seem to have a "no directory found" error. But it can start to be pulled into a separate utility now! @icarito should we make a gem out of /lib/exporter.rb, called mapknitter?

icarito · 2019-02-17T06:01:38Z

Great! About the Gem, we ourselves don't have an immediate need as the container will likely continue to pull from git directly.

jywarren · 2019-02-19T22:44:58Z

I guess i'm thinking of breaking this out as a separate Ruby library and independent repository so you don't have to include the whole MapKnitter container to use it, but we can start by just using this container, i guess. Can you try setting this up in a Google Cloud container so we can start trying to use it? Thanks!

I'm going to look for the 900913 error first as it might have cascaded to cause the others.

jywarren · 2019-02-19T23:18:17Z

So, i deleted the geotiff since we generate it twice in the tests.

Then i moved the 'delete directories' test to the end

I changed assert_not_nil to assert for a lot of assertions.

Finally, i added 3857 to try to bypass the 900913 error as per https://gis.stackexchange.com/questions/162767/gdal2tiles-py-gives-error-6-about-epsg900913-on-fresh-ubuntu-14-04-install

icarito · 2019-02-20T06:22:49Z

Okay, I see. I'm building a container with gdal 2.4.0 from the Debian repositories for the Testing distribution "buster". I'll put the Dockerfile in a pull request here when it works. I'll be adding Ruby and ImageMagick. I see buster has Ruby 2.5.1 - hope this is fine? Otherwise I can downgrade to Stretch (current stable, with Ruby 2.3.3 and GDAL 2.1.2).

icarito · 2019-02-20T07:24:22Z

Okay I've built a container including GDAL, Imagemagick and Ruby, and pushed it to the Docker Hub.
That means you can run it right now by using docker run icarito/gdal_ruby_imagemagick:buster - it'll pull directly from the Docker Hub. I've also pushed it to GCE but now it needs an interface to interact with the world.

@jywarren this should be ready for integrating, check out with docker run icarito/gdal_ruby_imagemagick:buster to begin integration with the export.rb script!

Regards,
Sebastian

jywarren · 2019-02-20T22:04:41Z

Thanks Sebastian - linking there now: #349 and I left some thoughts there too. Awesome!

jywarren · 2019-02-26T19:39:59Z

I believe everything but gdal2tiles.py is working and it just needed an API key, which I added.

jywarren · 2019-02-26T23:59:14Z

Great, only a couple small things left:

I think this may have to do with the GDAL version; this is a post by me:

http://osgeo-org.1560.x6.nabble.com/gdal-dev-gdal2tiles-py-cannot-find-EPSG-900913-sees-only-GDAL-1-6-1-td3748343.html

jywarren · 2019-02-28T23:32:22Z

I'm running GDAL 1.11.3, released 2015/09/16, on my local. Not sure what's in Travis though!

jywarren · 2019-02-28T23:36:48Z

+    key = "AIzaSyAOLUQngEmJv0_zcG1xkGq-CXIPpLQY8iQ" if key == "" # ugh, let's clean this up!

Hi @icarito if you have a moment, i'm a bit stuck here; i think we're down to the GDAL version on this last command. I've been trying to run it locally.

Here are the files that this should be runnable on: https://publiclab.org/i/29584.zip

gdal2tiles.py -k --s_srs EPSG:3857 -t "saugus-landfill-incinerator" -g "AIzaSyAOLUQngEmJv0_zcG1xkGq-CXIPpLQY8iQ" /app/public/warps/saugus-landfill-incinerator/saugus-landfill-incinerator-geo.tif /app/public/tms/saugus-landfill-incinerator/

And Mapknitter.org uses:

$ gdal2tiles.py --version GDAL 2.1.2, released 2016/10/24

Travis was same: GDAL 2.1.2, released 2016/10/24

Awesome I'll look at linking it to the Sinatra app for the API

sashadev-sky · 2019-03-28T11:34:29Z

@jywarren when I run mapknitter locally with rake test my output is the same as one of your earlier travis builds posts here: https://travis-ci.org/publiclab/mapknitter/builds/494340774#L2542. (I get the errors about removing files that don't exist, gdal2tiles.py doesn't exist). I made changes locally to fix these problems then realized your most recent PR https://travis-ci.org/publiclab/mapknitter/builds/507274672?utm_source=github_status&utm_medium=notification didn't have them in the first place. Any idea why?

Wanted to make sure I understand this PR before looking at @icarito new export API

@icarito

sashadev-sky · 2019-03-28T13:58:38Z

also am I remembering currently that the exports are supposed to export the images with the map background, not just the image overlays?

jywarren · 2019-03-28T21:20:37Z

Oh do we need to open a PR to solve the missing files errors as a distinct PR? And no, the export is just the overlays not the background. Thanks!!!!!

@jywarren hmm I don't know. Locally the tests wont pass if your root directory name has spaces in it, like for ex. on my computer I have the Mapknitter repo in a folder "Public Lab". Then it tries to run the commands 2 times: first on **/public then on lab/mapknitter/**. But if the root is https://mapknitter.org then it's fine.

To make it pass locally I just did root.gsub(" ", "\\ ") where appropriate. Would it make sense to add a PR with this change?

jywarren · 2019-03-29T01:14:42Z

ahhhhh, that makes sense. Or we could refactor this to use relative paths... what about that?

sashadev-sky · 2019-03-29T01:25:20Z

@jywarren would relative paths still work if the root is https://mapknitter.org? These could get more confusing because the files locally are nested at varied levels 3 or 4 levels deep

jywarren · 2019-03-30T00:01:29Z

Hmm. Which PR didn't have them? I believe we were able to resolve them all by re-creating the directories in the tests at the right moments. Can you share your test changes? I do think relative paths may still work, like ../../ should work in URLs as well... see how https://mapknitter.org/maps/../maps/cranston-test just goes to https://mapknitter.org/maps/cranston-test?

jywarren · 2019-03-30T00:02:42Z

But i just started making some changes to the extracted code here, that'll have to be refactored back in this repo once it stabilizes: publiclab/mapknitter-exporter#6

I am taking notes on the changes in publiclab/mapknitter-exporter#5 but I think you don't have to worry too much at this point... we're hoping to make all of that run itself externally.

sashadev-sky · 2019-04-03T02:48:43Z
