Map Options Icon
At the bottom right of every map view is the Map Options Icon. If the icon has a diagonal line it indicates you are using an offline map.
Tapping this icon will allow you to select which map type is used as the background to your map view. This screen gives you the option to Download Offline Maps, Select an offline map or standard map type.
Other than the offline maps you have downloaded all maps require a data connection.
Premium Offline Maps
If you are likely to be in an area with bad coverage or want to save your data then you should download an offline map for the area you will be caching in. There are premium offline maps and standard offline maps. The standard ones are the free ones available in versions of Cachly before 5.0. The premium maps are a one time purchase cost and provide faster drawing, contours, hillshades, county/region boundary lines, 3D buildings and have frequent updates. The different layers to be downloaded for Premium maps can be set in Settings. You can preview how this sort of map looks the first time you tap this action. To remove the preview map, switch to any other map type and swipe left on the preview entry and choose Delete.
If you only want to use the original free offline maps, look for the Standard Offline Maps option further down the Map Types list.
After purchasing the one time, lifetime usage of premium offline maps, tap your continent and country and the map will download. In the case of larger countries there is a further level, viz state or multiple state regions.
After you have downloaded the map it will be available for use as the background map.
The Map Types available are:
- Premium Offline Maps
- Apple Maps
- Satellite Flyover
- Hybrid Flyover
- Google Maps
- Standard Offline Maps (free)
