OSM Statistic Tiles

OSM Statistics Tiles

The goal of this dataset/project would be to generate geospatial statistics based on OpenStreetMap data and stored as JSON and PBF formats. These pre-computed tiles would enable data scientists to perform complex geospatial analysis at a country wide scale with minimal CPU processing.

Geospatial statitics

There could be thousands of different geospatial statitics that could be generated from a simple OSM dataset within a given BBox, here's a list of the most useful geospatial statitic that would be defined:

  • highway=* (path, residential, secondary, etc...)

Geocode as many addresses as you'd like with a powerful Python and Google Geocoding API combination
"""
Python script for batch geocoding of addresses using the Google Geocoding API.
This script allows for massive lists of addresses to be geocoded for free by pausing when the
geocoder hits the free rate limit set by Google (2500 per day). If you have an API key for paid
geocoding from Google, set it in the API key section.
Addresses for geocoding can be specified in a list of strings "addresses". In this script, addresses
come from a csv file with a column "Address". Adjust the code to your own requirements as needed.
After every 500 successul geocode operations, a temporary file with results is recorded in case of
script failure / loss of connection later.
Addresses and data are held in memory, so this script may need to be adjusted to process files line

notes on OpenMapKit (OMK), specifically mbtiles and osm files

#OpenMapKit (OMK) https://github.com/AmericanRedCross/OpenMapKit/wiki

  • install node
    • install the following packages tl, mbtiles, tilelive-http
    • npm install -g tl @mapbox/mbtiles tilelive-http
  • go to http://bboxfinder.com/ and box your area
    • should return your cooridinates in the following order: lng-min, lat-min, lng-max, lat-max
  • open terminal/command line and cd to your project folder and run the following:
  • tl copy -z 13 -Z 20 -b '{{lng-min}} {{lat-min}} {{lng-max}} {{lat-max}}' 'http://a.tile.openstreetmap.fr/hot/{z}/{x}/{y}.png' mbtiles://./{{myFileName}}.mbtiles
