Reset a docker image to initial state

Is there a good way to display map tiles dynamic and real time?

How can I check what version of mapnik I am using in python?

QUESTION

Reset a docker image to initial state

Asked 2019-Aug-27 at 06:12

I'm new to docker and recently I tried to use setup openstreetmap-tileserver. I tried a manual installation by cloning the project and run docker build -t SampleMap and docker run -v openstreetmap-data:/var/lib/postgresql/10/main SampleMap import and then run the proper command to run the container. I got three images using docker image ls:

When you create a container from your image, you mount a volume, using the -v option: docker run -v openstreetmap-data:/var/lib/postgresql/10/main SampleMap import

Your persistent data is stored in openstreetmap-data. That file/folder is not in your container (that is created every time), it is mounted from your host's filesystem. That's why it persists

QUESTION

Is there a good way to display map tiles dynamic and real time?

Asked 2018-Nov-15 at 09:03

Ⅰ using python-mapnik(linux)+postgis

I've tried using mapnik to show big data(aboult more than 600,0000 polygon features with much points in postgis),I display it real time from python service without cache. but i meet the problem： 1.At the beginning，load table from database lost much time 2.when I zoom to 12level,map tile will loading slowly

Ⅱ using python(flask)+postgis(MVT)+mapbox-gl

1.display 100,0000 features(simple polygon) so fast,but display big data(aboult more than 600,0000 polygon features with much points in postgis),i find selet query need much time. it's slowly than mapnik

Now I don't know how to complete my research about displaying big vector tiles fast and realtime!!

Is there a persion like me who are interested in quickly displaying data??Any help or suggestion would be appreciated! At last ,forgive my poor English descrption.

some information about vector tiles I've found,maybe is useful to somebody like me：

You may want to reduce as much as possible the amount of data being transferred from your database to your rendering engine.

This blog post from CARTO may give you some ideas even it's focused in point data.

For polygon datasets, in order to reduce the amount of data moved to the renderer you may want to create simplified versions to use based on the zoom level. Mapshaper is a nice tool to simplify polygons but still retain their topology. And in any case, always combine ST_RemoveRepeatedPoints with ST_SnapToGrid to be sure you are not wasting rendering CPU with wasted pixels.

I am using Python 3.5 and the mapnik library bindings available through the python-mapnik project. I have multiple versions of the mapnik library on my machine, how can I do a sanity check to see which version of mapnik the is being used by the python bindings?

There may be a better way but the package in question has a module paths which can be inspected to reveal what is being bound:
