search for: zipcodes

I am regularly running into a problem where I can't seem to figure out how maintain correct data order when selecting data out of a dataframe. The below code shows an example of trying to pull data from a dataframe using ordered zip codes. My problem is returning the pulled data in the correct order. This is a very simple example, but it illustrates a regular problem that I am running into.

Quick question. Say I have a geographical database with counties and zip codes where counties have and belong to many zip codes. zip_codes (id, zip_code) counties (id, name) When I create the association table, the Rails way says to do the following: counties_zip_codes (county_id, zip_code_id). However, given that zip_codes.zip_code is itself a candidate key, I would much prefer to do the

i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data. For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population,

Is there any package that I could use for zipcode search. I want to display schools that near a particular zipcode. I have no idea how to do this.

I am interested in locating a script to implement a sampling scheme that would basically make it more likely that a particular observation is chosen based on a weight associated with the observation. I am trying to select a sample of ~30 census blocks from each ZIP code area based on the proportion of women in a ZCTA living in a particular block. I want to make it more likely that a block will

This is a stupid question I know, but it is driving me crazy - I am missing something simple and basic here. I am trying to update missing zip codes on a data table. I am doing something incorrectly as the data in the Source table is not being updated, only the value in the array is changed. How do I get this to update the actual DB record instead? def add_missing_zips #find all records in

...I have an excel sheet containing all the 51states of amerika devided by zipcode. the columns are : zip,city, state, latitude,longitude,count so now I want R to make a new table that I could use to draw a map. The table should consist the name of the state plus the count. Like I said I have all the zipcodes and the count for the zipcodes, so now I would like to calculate the numbers from the zipcodes of one state. .can anyone help me?I've been trying and seraching trough other blogs and pages but I fail to find something that helps me.

Hey, Does anybody know of a good Geocode library for Ruby, similar to Perl''s Geocode::Postal, that i could use in my rail app? I need to do some "within 5 miles" calculations of zipcodes and i dont have a nice ruby (or gem) utility to do it. any help would be appreciated. thanks adam _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

...ng problem that should be simple, though i am stuck with it. Please note that this is not a specific geonames problem, though i use it as an example - it´s just a basic problem with lapply. I use the geonames webservices with the R geonames packages which works almost smoothly. I have a vector of Zipcodes and i want to do a geonames lookup for all of them, which should not be a problem. Of course i could create a loop for that one, but i think lapply should be possible, too. The problem is to hand over the variable to the lookup function. lapply(zipcodes,GNpostalCodeLookup(postalcode=zipcodes,c...

I''ve looked through the messages regarding implementing a ZipCode search and I have a few questions to make sure I have my head wrapped around this. Here''s what I have. I have a database table called zipcodes with the following info (for example) 30310 Atlanta GA 33.727807 -84.41983 -5 1 That''s zip, city, state, latitude, longitude, timezone, and dst. So when a user comes to my site and they enter in an zip code, I want it to find all stores within a 20 mile radius of the zip code entered....

...index zip = params["zip"] @zip1 = Zipcode.find(:first, :conditions => ["zip = ?", zip]) lat = @zip1.latitude.to_f long = @zip1.longitude.to_f radius = 50 @bookstores = Bookstore.find_by_sql ["SELECT * FROM bookstores WHERE zipcode IN ( SELECT zip FROM zipcodes WHERE degrees(acos( sin( radians(zipcodes.latitude) ) * sin( radians(?)) + cos( radians(zipcodes.latitude)) * cos( radians(?)) * cos( radians(zipcodes.longitude - ?) ) ) ) * 69.09 < ?)", lat, lat, long, radius.to_i] end This is a proximity search by zip code.

I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank". This works fine until I introduce some more logic. What I''m trying to do is to validate

I see several mapping libraries but cannot find how to do a simple task. Starting with a vector of zip codes (in the United States and in Canada) I would like to automatically lookup the corresponding coordinates. Can you suggest a package and function that I should turn to? I would also like to automatically pull in the altitude, and some climate data. -- Farrel Buchinsky [[alternative HTML

Hi, I have two model say- ZipCode < ActiveRecord::Base belongs_to :state_provinces end StateProvince < ActiveRecord::Base has_many :zip_codes end if I do @zip_code.update_atribute(:city, "My City") its giving Undefined method updated? for StateProvince if I remove belongs_to specifier in ZipCode class then it work fine. Any alternate solution?? Thanks -- Regards, Himanshu
