Math.sin(Math.toRadians(270)) * Math.sin(distance/radius)* s(Math.toRadians(latitude)) When using the databases with IPv6 support (1.3.12, 1.2.7), IPv4 addresses are looked up as IPv4-mapped IPv6 addresses. , s(Math.toRadians(distance/radius)) - Math.sin(Math.toRadians(latitude))* Math.sin(Math.toRadians(latN)) ) ĭouble longW = Math.toRadians(longitude) + The ngxhttpgeoipmodule module (0.8.6+) creates variables with values depending on the client IP address, using the precompiled MaxMind databases. Math.sin(Math.toRadians(90)) * Math.sin(distance/radius)* s(Math.toRadians(latitude)) s(Math.toRadians(latitude)) * Math.sin(distance/radius) * s(Math.toRadians(180))) ĭouble longE = Math.toRadians(longitude) + s(Math.toRadians(latitude)) * Math.sin(distance/radius) * s(Math.toRadians(0))) Math.sin(Math.toRadians(latitude)) * s(distance/radius) + this you will get by querying the database against the zip codeĭouble latitude = Double.parseDouble(zipCode.getLatitude()) ĭouble longitude = Double.parseDouble(zipCode.getLongitude()) Double latN =Math.asin( Hello everyone, Are you using a GeoIP database service provider I have been using MaxMinds paid GeoIP2 Databases, the problem is that it seems to work. Here is the calculation in java if you really if you do not want to work with php This is the website which helped me a lot. ThenĬalculate co ordinates within the radius you want to search.
#MAXMIND GEOIP DATABASE DOWNLOAD ZIP#
After much research i found that you will have to download zip codes along with their latitude and longitude positions into a table. You may find a data sheet comparing our various GeoIP2 databases here and a high-level overview of our GeoIP2 solutions here. I could not find any service which offers API. This demo contains data found in the following GeoIP2 databases : GeoIP2 Country database.
