Sri Lanka Maps in Garmin GPS

Recently I received a Garmin GPS (nuvi 50) from my brother who is studying in China. The GPS looks fine but there are no Sri Lanka base maps installed in it. Then I tried to find a Sri Lanka road map that supports to the device. As I went through the articles I got to know that the format of the maps used in Garmin devices is a proprietary one. The map blocks are archived in to a single file which has the extension ".img" but not similar to DVD or floppy image file.

I found there are three methods to get Sri Lanka map to Garmin devices.

  1. Download from the Garmin map resources
  2. Download Sri Lanka maps from UMP (Unofficial Map Project)
  3. Download and convert maps from OpenStreetMap 
(PS: I found this link of OpenStreetMap which seems to support routable maps and very easy to download maps of any country including Sri Lanka. http://garmin.openstreetmap.nl/)

The first method is bit expensive and I don't think that it is worth to buy map from Garmin because they don't give enough details such as traffic details that is worth for the price. But if you need accurate and less-bugs maps you will like to use their maps. You can buy an updated Sri Lanka map from GPS Travel Maps. The following image is a screen shot of Sri Lanka nuvi GPS map from GPS Travel Maps.


The second method is free but totally worthless because the map has no actual road name other than the code of it like A1, B5 etc. Although it has code names for all most all major roads the rest of the map has only the map polygons but no further details. The only advantage is that it is much compatible with  nuvi 50 device. But if you are interesting you can download this old map from UMP Map of Sri Lanka  For details of how to install these maps with Garmin Mapsource software check this thread of Lakdasun forum.

The third method which I preferred is use Sri Lanka map from Open Street Map project and then convert it to the Garmin map format. This map includes all most all roads including the recently developed express ways with their terminal locations, POIs (branches of most Banks in Sri Lanka, Schools, filling stations etc.) and many more. And the best part is we can download and convert these maps for free. for more details about how to bring the open street maps in to a garmin gps device you may check OSM on Garmin. Anyway I'm going to share the map which I converted recently (2013), which can be used directly with your Garmin devices. 

You can download the map from here. 

(Yes it is incredibly small in file size yet have lots of details in it). 

Note that no software requires to setup this map in your GPS. Just plug your Garmin device to you computer using the USB cable and open the storage drive of it using my computer. Then replace the file "gmapsupp.img" in the device (deviceLetter:\garmin\ or deviceLetter:\garmin\Map\ or some where in the device, you better search for the location of this file with in the device) with the one you downloaded (you may backup the existing file before replacing if you think that you will need the existing map again). 

I installed this open street maps to my Garmin GPS without any problem. If you have any question regarding this feel free to ask me. This is the first post of my new blog and I hope to share my experience and other ideas which I think may common to many of you onward.

  4. Ravi, thank you so much for this. I am cycling around Sri Lanka at the moment as part of my world tour.
    I just found this page and downloaded the map. I don't know about other Garmin units but I'm using a bicycle Edge 800 unit. On this you can have multiple maps. I changed the name to SriLankagmapsupp.img and copied it to my memory card and BINGO! it works.
    Thanks so much, a good start to the new year.
    I'm in Jaffna now and heading down east coast and south coast back to Colombo.
    I'll buy you a Lion Stout or a tea or a short eat if I'm in your neighbourhood :)
    Cheers Richie

  6. Iresha,
    What is the brand and model of your car? is that factory fitted GPS? Most of car OEM GPSs works only for their own map file formats and it is very hard to convert our maps into their types. I may able to give a suggestion if you can share the type of your car GPS.

  14. All together for your GPS to work you should be in an area where you can get the radio signs from various distinctive satellites with the goal that they can be cross referenced. Excessively few satellites and the precision goes down, none, or one, and it's pointless. http://gpscustomerservice.com/update-a-garmin-streetpilot-c330

  15. Aside from its navigational capacities, numerous a wearing aficionado has likewise made utilization of GPS usefulness to help them accomplish more engaged activities. For instance, you can utilize your GPS beacon to compute how far and how quick you've voyage. https://purr-dev.lib.purdue.edu/members/1708/blog/2016/09/garmin-camper-660lmt-the-best-value-for-money

  17. The observing system or the operation control section is worried with following and holding the satellites in space. It screens battery control levels and charge levels. It likewise keeps a tab on the soundness of satellites and the uprightness of signs.http://www.talkmarkets.com/content/stocks--equities/should-you-buy-fortinet-on-the-dip?post=110428

How to Send Executable (.exe, .ocx, .dll, .com, .bat) Files in Gmail Without Changing the File Extension?

Why Gmail doesn't like exe files? If you use gmail as your email service probably you should be getting frustrated with it when you want to send files with the extensions exe, ocx, dll, com or bat. These executable stands for some files which can be executed independently within a typical operating system and there is a huge probability to contain computer viruses or malware in these types of files. Since these kind of files can be executed independently any virus that the file carried will infect our computers very easily.

Although this is not a problem in other free email services like yahoo, as Google has grabbed a big part from the services which we use for our day to day cyber needs, we can't move in to another service just because of this problem.

What happen when we are trying to upload an executable file in Gmail? When we attach an executable file first it upload the whole file and check on several criteria such as file extension (whether it contains .exe, .dll etc) a…

What minHessian, Octaves and Layers mean in SURF (Speeded-up Robust Feature)? QA

My previous article in this blog is about a discussion on measuring image similarities with BOF in a large database. It is an extracted part from a forum of an article posted in CodeProject "Bag-of-Features Descriptor on SIFT Features with OpenCV (BoF-SIFT)". This article is also an extracted part from the commenting section of the same article in the code project. As I described in my previous article, many people who used visual features do not have a proper understanding over the feature extraction and description algorithms because of these algorithms contain a lot of mathematical procedures which are difficult to understand with an average mathematical knowledge. The question which is about to discuss in this article has proved the above said fact and also the fact may cause the users to limit the usage of such features in their studies and applications.
Lets begin the discussion.

Q. I just wanted to ask why the minHessian value is 400, the number of octaves is 4, and th…
