Search & Lookup Website Hints and Shortcuts, by GizmoGuy411.

This website is a comprehensive list of switches and parameters that can be used to construct URLs, to extract just about any kind of information. Or as GizmoGuy411 puts it, "a wealth of info in how to use in interesting ways".

Geocaching Quick Search by Jeff Boulter

A powerful and flexible search engine for caches & trackables, but best of all it has a "smart" mode which will try and interpret any input intelligently. For instructions to use it, click the help link on the page.

Coordinate Conversion

GPS Coordinate Converter by Jeff Boulter

Takes coordinates in a variety of formats, and spits out decimal degrees, degrees/minutes/seconds, decimal minutes, and UTM

Secrets of The West Coordinate/Datum Conversion

Converts between different coordinate representations, and between a number of datums (but this is only optimised for North America).


GPS Visualizer

"An online utility that creates maps and profiles from geographic data. It is free and easy to use, yet powerful and extremely customizable. Input can be in the form of GPS data (tracks and waypoints), driving routes, street addresses, or simple coordinates."

Plot tracks, waypoints, elevation profiles; elevation lookup; coordinate calculators; and more.


geo-*: Rick Richardson's Linux tools for geocaching

" ...various tools for geocaching. Some are designed to turn the clickly-clicky-scroll-clicky-clicky messes that are and into a set of tools which you can use in a batch or cron mode to establish your normal caching routine, backup your caches and cache logs, etc. Others are used to enter new waypoints, a free geocoder, create custom maps of waypoints, etc"

Coordinate Checkers

These are websites that are typically used with puzzle caches, to allow geocachers to confirm the final coordinates for the cache. These sites typically provide a customised link which can be placed on the cache listing, allowing easy access to the checker. Some of the more popular checkers are listed below. Each has it's own advantages and disadvantages, so experiment and use whatever feels right.

Evince - Simple checker that only allows one guess avery 10 minutes, which is good for preventing attempts to use "brute force" guessing to identify coordinates. You can either require an exact coordinate match, or allow a small error (by specifying a distance from the coordinates).

Geochecker - Similar to evince, but allows each user 10 attempts every 10 minutes.

GeoCheck - More powerful checker, allows you to provide "not quite right" messages for certain inputs, and to display the total number of correct & incorrect attempts. Also allows the owner to see attempt statistics, and plot attempts on a map. Allows each user 10 attempts every 10 minutes.

Certitude - Provides the ability to register your attempt with your geocaching account, to "certify" that a particular user entered the correct coordinates. Allows each user 10 attempts every 10 minutes.
