Offline Maps: A new version (bugfix) and update of the base URL’s

I just posted release 1.4.1 of my OfflineMaps application.

There was an error in the 1.4.0 verszion which prohibited the downloading of tiles, which is what the application is all about.

I also noted that Google updated their base-URL’s, so if you download the above version, start by updating the base-URL’s.

You can download it on the project page

Hope you enjoy it !!

Offline Maps: Added automatic URL updating – version 1.4.0

I released version 1.4.0 of the application last weekend.

What’s changed

Not much actually, but I think that what did change will make the application more usefull.

It is now possible to change the base-URL used by the Google Server for obtaining the tiles. Google has the habbit of changing those URL’s quite frequently. And allthough nothing fundamentally changed about how the URL is composed ever changed, it did result in not being able to get the tiles and thus making the applicatio rather useless.

All that has changed now. For those who now how to get at the base-URL (and I will post on how to do this later on), they can just adapt the base-URL used and save the new values.

For those less technical, they can retrieve the latest base-URL from the Offline Maps page on this blog by the click of a button.

Enjoy !!!!

Offline Maps: oops, fixed small/severe bug – version 1.3.1

I recently released the 1.3.0 version of my Offline Maps application. This weekend I started preparing for our holidays and noticed several crashes: there was an error in the tile caching.

The error affeced only the desktop application and is now fixed so everything should work fine now. The corrected version is now version 1.3.1

And what do we learn from this: test thouroughly !!! I urgently need to setup some automated testing for this application. It started of to be a quick application to download some tiles from Google Maps so I thought I wouldn’t need any testing but it is quickly expanding with other functionality.

Visit the Offline Maps page to download it.

Offline Maps: Added Import Layer and corrected version for Windows Mobile 6.0 – version 1.3.0

I’ve just released version 1.3.0 of the application.

The application allows you to download tiles served by google maps and openstreetmap to your harddrive and then view them offline, thus without an internet connection.

What’s changed

I have added a layer which allows you to import other maps like bitmaps and calibrate them with Google Maps or Open Street Maps.

I also fixed some bugs in the mobile version. It now works faster (allthough on my HTC Touch not fast enough yet) and GPS functioanlity is working.

You can get it at the Offline Maps page

Any remarks are always welcome.

Oh yeah, if you go look at the Offline Maps page: guess where we are going on holiday this year 🙂

These are some links I used for implementing the Import layer. Allthough it turned out I didn’t need the transformations for scaling.

Offline Maps: Updated user interface and released version for Windows Mobile 6.0 – version 1.2.0

I’ve just released version 1.2.0 of the application.

The application allows you to download tiles served by google maps and openstreetmap to your harddrive and then view them offline, thus without an internet connection.

I’ve updated the user interface which is now much user-friendlier (I think)
There is also a preliminary version for Windows Mobile 6.0 with the offline server functionality and the routing and gps layers. It is however very slow but I’ve not tested it on an actual mobile device, only in the emulators provided by Microsoft.

Any remarks are always welcome.

Offline Maps: released version 1.1.1.3

I’ve just released version 1.1.1.3 of the application.

The application allows you to download tiles served by google maps and openstreetmap to your harddrive and then view them offline, thus without an internet connection.

Google changed the base URL for the map-tiles which made the previous version unusable.
People with programming knowledge could change the code, but those using the binaries could not use the application for map-tiles.

That problem has now been solved.

Offline Maps: added GPS layer – version 1.1.0.2

I finally added the GPS layer. It allows you to know where you are but it is NOT a routing application. This means you can not find the shortest route between to locations.

So what can you do?

You can:

  1. do everything you could in the previous version.
  2. View tiles served by Open Street Maps (thanks to Michael Collinson)
  3. Find your position using a GPS
  4. Trace a route on the map and save it
  5. Display a previously saved trace
