Script to download all layers from SimpleGeo storage to CSV files

gistfile1.rb

# The following script allows to export a SimpleGeo Storage layer to a CSV
# You have to change the credentials and the layer that you want to export
# It will generate a CSV file with the name of the layer
#
# Author: Javier de la Torre ([email protected] @jatorre)

#Adapt the following to your SimpleGeo credentials. Get it from the UI.
oauth_token="token"
oauth_secret="secret"


#-----------------
require 'rubygems'
require 'simplegeo'
require 'csv'

SimpleGeo::Client.set_credentials(oauth_token, oauth_secret)

#get all layers for user
layers = SimpleGeo::Client.get_layers()[:layers]

layers.each do |layer|
  CSV.open("#{layer[:name].gsub(".","_")}.csv", "wb") do |csv|
    next_cursor=""
    header=false
    #loop until next_cursor is nil  (pagination)
    #the query basically look for all records within the whole world as I couldnt find a way to download a full layer
    while next_cursor do 
      puts "."
      res = SimpleGeo::Client.get_nearby_records(layer[:name], 
          :lat => 0,:lon => 0, :bbox=>'-90,-180,90,180', :limit=>500,:cursor=>next_cursor)
      next_cursor = res[:next_cursor]
      res[:records].each do |row|
  
      #add headers
      if !header
        csv << ["id", "lat", "lon","created"] + row[:record].properties.keys.map(&:to_s) - ["layer"]
        header=true
      else
      #add records  
        csv << [row[:record].id,row[:record].lat,row[:record].lon, row[:record].created.strftime("%Y-%m-%d %H:%M:%S")] + 
          row[:record].properties.values - [layer[:name]]
      end    
    
      end
    end
  end
end

Great!
