This application can operate in full without Internet connectivity. The only requirement is to cache required data in the browser before offline use.

1. Application (including GIS vector data)
This is cached automatically just by visiting this page. To obtain the latest updates, be sure to re-visit and refresh the page when online.

2. Basemap
The basemap is too large to cache at full extent in all scales. While online, zoom and pan to all required areas and scale levels. Everything you see will be cached for offline use. You may also use our tool for this.

3. Test
Test the application in offline mode before use.
