How often do we find ourselves with poor or no mobile Internet connectivity?
* Even in big cities wi-fi coverage can be very spotty.
* Many mobile devices lack 3G/4G all together, so outside of the office/home means no Internet.
* Data plans are expensive, if you are pulling data from the Internet using your plan, that can end up being costly. Many thus choose to limit the use of their data plans.
Imagine viewing interactive maps and overlay layers regardless of internet connectivity. Continue to collect and edit data even in the most remote of areas. There are now some excellent offline mobile ArcGIS solutions available. Most are canned, installed mobile apps. They do what they do, no more no less. We’ve been looking into developing a more flexible approach. One that provides the ability to customise the look and feel, and add or alter existing tools to fit your workflows.
That could mean custom forms or redline tools which work online and offline.
Need your ArcGIS App to Work Offline?
As the diagram above shows base maps tiles and feature layers from ArcGIS are copied to a database which is on your mobile device. When poor or no Internet connectivity simply switch to this local data source and continue working. If you are editing, all you changes are stored in the local database to be pushed to ArcGIS when you are back online. Simple.
Below is a short demo showing an offline editing application which uses this approach. Notice the intuitive workflows. This is ideal for those without GIS experience.
We have built a library called DisconnectedJS which makes it easy to build an ArcGIS application, or extend an existing app, to provide offline capabilities. use this library yourself, or have us build an application for you which leverages the offline capabilities provided by DisconnectedJS.
