Geo Tags & Headers

  • Geobytes Headers
    This method allows you to access the geographical information at the server-side and use it with PHP, ASP, Perl or any other kind of server-side script. GeoSelect inserts the viewer’s location into the HTTP headers before the request is passed to any applications. There are more than 20 Geobytes headers to choose from. You can also use the HTML-style <geo> tags in conjunction with the Geobytes Headers.
    There are quite a number of headers that you can use to customize data within your web application, a list of the available headers is included below.
  • The following section contains a description of the supported Country, Region, City, DMA and Subnet tags and headers.

    Description of headers
    The purpose of each of these fields is documented below.

    • RegionId; this field is an internal key used to relate a specific row in this table to related rows in the “Cities” table.
    • Region; this field is the character representation of the sub-country geographical region. For example, the value of this column might be the state “Florida” in the USA or “New South Wales” in Australia.
    • Code; this field is a 2 character code used to represent the general abbreviation for a sub-country geographical region. The were referenced from http://www.mindspring.com/~gwil/statoids.html#codes Each region has a unique code within a given country, and existing official codes were used where possible. “Official” can mean various things, but the ISO 3166-2 codes have been favored http://www.iso.org/iso/en/prods-services/iso3166ma/04background-on-iso-3166/iso3166-2.html. The codes are mnemonic. They consist of the first letter in the subdivision name, followed by a letter that occurs later in that name, unless it was impossible to assign unique codes by that rule.
    • ADM1Code; this field is related to the “FIPS104” field in the “Countries” table. Where the “FIPS104” code is used to identify a geopolitical region at country resolution, the “ADM1Code” is used to identify a geopolitical region at a sub-country region.

    Description of city headers
    The purpose of these fields is documented below.

    • CityId; this field is an internal key used to relate a specific rows in this table to related rows in the “Subnets” and “NearbyCities” table. This is the primary key and is unique. The number “1225” for example is the key for Melbourne, Australia.
    • City; this field is a character representation of the actual name of the city. For example “New York”, “London” or “Paris”. This field should not be used as the key for queries since the names of cities are not globally unique.
    • Longitude; this field is used to store the approximate longitude of the city specified by the rest of the row.
    • Latitude; this field is used to store the approximate latitude of the city specified by the rest of the row.
    • TimeZone; this field is used to indicate which time zone the city is in. For example, the “TimeZone” field value for Sydney, Australia is “+10:00” being UTC (or GMT) plus 10 hours. The time is represented in UTC (Coordinated Universal Time). UTC was formerly known as GMT (Greenwich Mean Time). See ISO8601:2000(E) for further information on time zone representation. The ISO is available at http://www.pvv.org/~nsaa/8601v2000.pdf
    • LocationCode; this field is a 4 character alpha code used to represent a city within a given country and region. The code consists of the first letter of each word, then followed by the next 2 characters in the last word. If the city has only one word, then the first 4 characters would be used. When generating these codes if there was a duplicate code generated, then the next letter in the city name would be used. If a duplicate code is still found, then the last character of the code is replaced by a letter from the alphabet in descending order.
