Map Making Support / Issues with State Lands Borders-Only Map
« on: December 06, 2010, 04:40:43 PM »
I am trying to make a map which shows ONLY LA state wildlife management area boundaries for use in conjunction with an existing La State Topo. My efforts are thwarted at the second-to-last step: Making the preview file in Mapset toolkit (v 1.77 Beta).   I get a "convert failed" message.

I have the shape file to start the process, and I followed the process for converting the area data into line data, using How To Create Garmin Topo Maps - Part 7 - Borders . I think I am getting through this part of the process OK, but it should be noted that instead of converting a single area to a line (a single state border in the tutorial), I am working with multiple areas as one file.  In any case, I am able to save the converted .shp.

I then move on to  How To Create Garmin Topo Maps - Part 8 - Combining Data, where I successfully build an .mp file.  One thing I am doing when I create the MP is I am selecting "all loaded data", instead of limiting to some Lat/long for the Export Bounds. I am also NOT using any gridding; just one data file. I am using the template and all of the suggested scripts. 

Next, I create the image file using How To Create Garmin Topo Maps - Part 9 - Compiling Data    Of course, there's not much to compile, as i am only using a single data source for the .img. This step seems to work fine.  Then I open Mapset toolkit (v 1.77 Beta), and the interface looks quite different than the one on the tutorial. (I don't see any place to download anything BUT the Beta at the Mapset Toolkit site).  And I do hit "START", not "compile".  That is when I get the convert failed error message. 

Obviously, there is more detail.  If someone want's to PM me with an email address, I could send some screen-shots of various settings.

Any thoughts ???

Much appreciation,


GPSr Units / Memory Format Quesiton on Etrex Vista HCx
« on: November 18, 2010, 12:14:46 PM »
I am looking to buy a Vista HCx, and I have been looking at memory.  I see the unit takes the micro sd cards up to 4 mb, but it seems that what is MOSTLY available for purchase online - at least in 4gb - is the microsdhc format.

according to this site: http://www.mobileburn.com/definition.jsp?term=microSDHC

MicroSDHC cards are a faster, higher capacity version of the microSD memory card standard. Any microSDHC compatible device can read both microSDHC and older microSD cards, but a microSD compatible device cannot read microSDHC cards.

Does anyone know if the Vista HCx can use the microsdhc cards?



General Discussion / A Couple of Newbie Questions Here
« on: November 17, 2010, 01:20:33 PM »
Hi All,

New here, and trying to get the basics. I have a Garmin 276c, which takes only the proprietary Garmin data cards. I currently have only a preloaded Garmin Marine map card in the unit.  However, I plan to purchase an Etrex Vista HCx, and I want to prepare and practice for loading data to an SD card for that unit. 

I have Garmin Mapsource loaded. I have also downloaded the following map from GPSFileDepot:


I have run the .exe and the files are all in a folder titled Lousiana Topo. There is a .tbd file and  .img files, one of which has the same name as the .tbd There is no .typ

Of course I do not want to overwrite the data on the preloaded Garmin datacard I have, but I want to make the above map data visible to mapsource, so that it can be selected for later use. I have read the following tutorial: 


which says:

It could be easy: If you downloaded the map from GPSFileDepot and it had a setup wizard (where you kept clicking next to install the map) the files are already loaded into MapSource so you can just load the maps onto your GPSr with this tutorial.

Here is the tutorial referenced above:


The map does not appear, even though I used the .exe I therefore assume that I need to place the data somewhere so that mapsource can "see" it.  Can anyone tell me where that is, and what structure the data should take?

Also, I cannot seem to see the data on the installed mapcard on my 276c using mapsource. Should I be able to see that data, or view the maps in mapsource?
