Includes two apps for testing browser-based geolocation on different devices. It lets you track your location as well as play with the different Geolocation API properties. This can be used on a desktop browser, mobile browser or within a PhoneGap project.

index.html - let's you experiment with all the different settings as well as accumulating track points.

field-location-template.html - is an experimental mobile app that demonstrates one approach to helping field workers determine the best single location. The app uses visual clues, averaging and center point averaging. It's built using bootstrap.

html5-geolocation-tool-js's Issues

why are you computing median values?

Was there a reason you are calculating median values? You don't seem to use them in the app @ https://esri.github.io/html5-geolocation-tool-js/field-location-template.html

Geolocation broken - update to https

Update sample apps to https.

geolocation fails on Chrome when used with mock location provider

Related to the following Android OS error: E/LocationClientHelper: exception when setting module id java.lang.IllegalStateException: Unable to get current module info

Reference the following Chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=737327

Average distance between updates not working

Need to capture NaN's

Update code

Update to latest JS API and implement jQueryHelper library.

Geolocation not working over HTTP

The latest versions of Chrome and Safari 10, including Safari on iOS 10, will block geolocation unless the web application is served over HTTPS. Also note, all your content will have to be served via HTTPS, you won't be able to mix HTTPS with non-HTTPS.

Screenshot links broken

Change to relative pathnames

share location is not given in this code

please update the code with share location option

Any methods to detect geolocation spoofing?

I have been searching online for established methods for checking for geolocation spoofing but could not find any detailed explanation of the techniques. One comment on StackOverflow suggested to detect extreme speed or distance changes but Isn't that also spoofable and how to account for the case when user spoofs directly to the location and then turns on the app.
