Download the daily improvement files in OSM from: http://planet.openstreetmap.org/replication/day/000/000/
https://github.com/Rub21/osm_osm_visualization/blob/master/data/retrieve-day
Run:
$ ./retrieve-day arg1 arg2 Where:
- arg1 is: 01/09/2014 = 484 (start file)
- arg2 is: 04/09/2014 = 574 (end file)
The Script is based in : https://github.com/ericfischer/ebola/blob/master/retrieve-hourly
Example:
ruben@rub21:~/osm_visualization/data$ ./retrieve-day 448 574 we use: https://github.com/Rub21/osm_osm_visualization/blob/master/data/get-edits: modified from: https://github.com/ericfischer/ebola/blob/master/get-mamou-edits
Run:
$ ./get-edits file minlat minlon maxlat maxlon > newfile.geojson Example: Bounds from San Francisco:
$minlat = 37.716045; $minlon = -122.51781; $maxlat = 37.817006; $maxlon = -122.34924; Process a file
Example: ruben@rub21:~/osm_visualization/data$ ./get-edits 485.osc.gz 37.716045 -122.51781 37.817006 -122.34924 > sf485.geojson Is possible to execute all the files:
Run:
$ ./process_all start_file end_file minlat minlon maxlat maxlon
Example:
ruben@rub21:~/osm_visualization/data$ ./process_all 484 574 37.716045 -122.51781 37.817006 -122.34924 It will take a while depending on the number of files are.
If you want to process the file for some especific user use the file, you have to edit the file: https://github.com/Rub21/osm_visualization/blob/master/data/get-edits-by-users, exactly the line https://github.com/Rub21/osm_visualization/blob/master/data/get-edits-by-users#L64 and add more users, then
Run
$ ./get-edits file minlat minlon maxlat maxlon > newfile.geojson Example:
ruben@rub21:~/osm_visualization/data$ ./get-edits-by-users 499.osc.gz 37.716045 -122.51781 37.817006 -122.34924 > sf499-users.geojson You need to install Tilemill, and clone Projectmill
git clone https://github.com/mapbox/projectmill.git In this case we need satelital imagen :
we use ericfischer' project tile-stitch, cloning in your machine an run:
ruben@rub21:~/tile-stitch$ ./stitch -o sf.png -- 37.6787 -122.5171 37.8270 -122.3338 13 http://a.tiles.mapbox.com/v3/openstreetmap.map-4wvf9l0l/{z}/{x}/{y}.png then we check the size of imagen: in my cas is : "width":1068, "height":1093
I create a project in Tilemill called sfbuildings: https://github.com/Rub21/osm_visualization/tree/master/tilemill-project/sfbuildings
We need to configure this file https://github.com/Rub21/osm_visualization/blob/master/make-config.py, the exact lines are:
project={ "source": "sfbuildings", #name of projet in Tilemill "destination": "sf"+ str(x), "format": "png", "minzoom": 1, "maxzoom": 16, "width":1068, #it is a width form satelital imagen "height":1093, #it is a height form satelital imagen "mml": { "Layer": [ { "Datasource": { "file": "/home/ruben/osm_visualization/data/sf"+str(x)+".geojson" #directory of files for process } } ], "advanced": {}, "name": "line"+ str(x) } } Run:
$ python config.py arg1 arg2 where: arg1: is the number of the first file that we dowload before. arg2: is the number of the last file that we dowload before.
Example:
ruben@rub21:~/visualization/projectmill$ python config.py 484 574 and then execute:
ruben@rub21:~/Apps/visualization/projectmill$ ./index.js --mill --render -c config.json -f -t /usr/share/tilemill After:
That files are created in: /home/ruben/Documents/MapBox/export.
Copy and paste the satelital imagen from folder tile-stitch to /MapBox/export and renamed the file a smaller number of the first file that was created by Tilemill:
my first file is called: sf484.png, I renamed the imagen file to sf483.png and then run:
Example:
ruben@rub21:~/Documents/MapBox/export$ mogrify -format gif *.png && gifsicle *.gif > anim.gif ruben@rub21:~/Documents/MapBox/export$ gifsicle --loop=0 --colors 256 *.gif > anim.gif The result is:
