You can convert map images to GPS maps, and you can use the created maps completely offline. Custom Maps works on phones, tablets, and on Chromebooks.Custom Maps can use maps in JPG and PNG images and PDF documents.
You can find useful map images in national and state park brochures, many of which are available online. You can also take pictures of paper maps. You can create your own GPS map for the park from those before you get there, so you will know where the trails lead and where the facilities are.
Watch the short video above to get a quick tutorial on how to use the app.
For those who don't like to watch videos, here is a brief summary on how to create a map:
- Before opening Custom Maps, download a map image or PDF to your phone
- With Custom Maps, select the map file on your phone you want to turn into a GPS map
- Select two points on the map image and find the corresponding points on Google Maps
- Preview the map image overlaid on Google Maps to verify the map image is accurate
- Save the map to your phone
If you want to get creative, you could draw your own additional annotations on the jpg or png map image using some drawing app. Custom Maps does not provide image annotating features.
Privacy Policy
Custom Maps does not collect any personal information, and does not send any information from your phone or other Android device to any servers. All the functionality is performed on your phone without any data being sent to any servers.
Google Maps API is used in aligning the map images, so Google Privacy policy applies to that part. But Google Maps API is used anonymously to only display a map of the area on the map image. No personal information is sent to Google either.

I rated this a 5 because when it works it is literally awesome. BUT, all my old maps are gone and need to be rebuilt. I tried stopping the app, clearing cache, allowing access to storage but it doesn't seem to notice. **I fixed this by clicking on each of my maps in the "Files" app and opening them with Custom Maps. This seems to have loaded all the maps into the new local storage. It only took a couple of minutes.

It works exactly the way it's supposed to. Pick points on your map you can also find on Google Maps, line them up, and accept them. If you have internet data access, you can also view the map you've created on Google Earth. One always wishes one could have more. For example, a user might know the coordinates of points from his GPS receiver and it would be a convenience to input the points instead of depending on Google Maps. Also, it would be valuable to see track points plotted on the map, as one sees on GPS devices. Until such an app exists, this is the best one I've tried.

This app is fantastic! I've been using it to get realtime location on a scanned copy of an old paper map. It's approximate, of course, but it's far better than trying to do it manually with few obvious visual markers. The GPU acceleration makes a big difference with large images (as you'd expect). I particularly like that once you start adding alignment markers they are used to help aligning subsequent markers. The option to display the current location details, including the GNSS accuracy, is really useful. Is there a way I can show my appreciation for your work? I'd gladly pay for this app, or at least like to buy you a coffee, beer, etc.

This app did save my life. I used it for hiking in Hokkaido where an electronic map was not available to me and Google just didn't work as there's no mobile reception in the mountains. All I had was just a picture of the park topo map and this app. I would have lost in the winter snow storm and died there if it's not this app. Thanks!

I've been doing some offroad/woods driving using maps from whatever park I visit. The problem is some trails are easy to miss just looking at a static map. Google maps gps mapping is great but it doesnt match the park map. Google maps is either missing valid park trails or has ones which are not valid trails. This looks like exactly what I need to take a park map and use the gps position on THAT map. I havent tried it anywhere except at home, but this seems to do exactly what I need. Thanks!

This is really cool. Grab all your maps in one month from the OS for £5 then load them into here. No more aggro when you're offline. Just one request: when I zoom out it should show all the maps within the area I've zoomed to. At present it just shows grey in places it has a map for. That calls for a map style property e.g. 25k, 50k, for deciding between multiple options. For overlaps, remove equal amounts from each map.

Fantastic for Georeferencing images using Google Maps satellite view and then saves it as a .kmz file, which is super handy. One shortcut that took me a while to discover is you don't really need to spend time rotating and zooming the map as long as you match up the point on the map with the point on the satellite. But the rotating and zooming is very handy for confirming if you are unsure.

Very easy and intuitive to use. Please pretty please put a geo tracker, and it would be perfect. Works with pdf maps. Marko thanks for the prompt reply. I don't know how to use the custom map with a different geo tracker app. I really would like the ability to see my track on your custom map app. Another way would be to convert the custom map into a .kap or .bsb file so I can use Opencpn to create tracks on the .kap map
