General Discussion / Re: usgs maps

You can get USTOPO in Mobile Atlas Creator with this code :

<?xml version="1.0" encoding="UTF-8"?>
<customMapSource>
   <name>USGSTopo Basemap</name>
   <minZoom>0</minZoom>
   <maxZoom>16</maxZoom>
   <tileType>png</tileType>
   <url>https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer/tile/{$z}/{$y}/{$x}</url>
   <tileUpdate>None</tileUpdate>
   <backgroundColor>#000000</backgroundColor>

The tiles are already Spherical Mercator and MOBAC will write a Garmin Custom Map directly.

But it seems your maps are out of date - the railroad is no more!  ;)

MAPC2MAPC will reproject from most existing projections, doing the calculations automatically.

[I declare an interest : I wrote it]

I suspect Garmin get roads etc from USGS. I have been working with USGS data and there are several errors - the worst was a road running through the middle of a lake!

Map Making Support / Re: SD card to PC, searchable?

CGPSMapper creates IMG and IMG.IDX files when it compiles a MP. Using Mapset Tool KIt, you need to copy the IMG.IDX files into the Mapset directory before you start the process of building the map.

C:\ProgramData\Garmin\Maps\ sometimes works for me!

Mail me if you would like to try a vector map for WV - usable with BCNav, Locus and Orux.

If you have the track as a GPX file and load it into GPSU that should tell you what you want. The free version should suffice. www.gpsu.co.uk

The TYP file is only needed to change from Garmin defaults. The contours are types x20, x21 and x22 (minor, intermediate and major).

By adding entries to the TYP file you can override the default display.

There is no way to flex this according to altitude with an existing map. To do that, the map would need to have been compiled with different line types - such as 'minor contour over 5000 feet'.  Possible in theory but impracticable unless you have the source data or can write code to decompile the map and have the rights to do it.

GPSr Units / Re: Best big screen GPS for custom maps

There is a Windows program - MAPC2MAPC that will convert your existing custom maps to various formats for Android and iPad Apps.

And there is an App called EasyTrailsGPS that says it will use the Custom Map KMZ files directly (but I have not tried it).

MapPlus will accept downloaded maps but not in Garmin format. To load Garmin maps into any iOS app will need conversion which raises technical and licence issues.

If you had an Android then the Orux app will display Garmin maps but not (IMHO) bery prettily.

Another combination that might be useful is the Vectorial Map app and downloadable OpenAndroMaps (which work on iOS)

There's no reason why you should not run more than one app at the same time to get the result you want.

I sell MAPC2MAPC for $20 - but I have still had to put in a lot of work to stop hacking and the generation of fake codes. Being cheap is no protection!
#59
Reprojection is only relevant to Raster data as Vector data has no associated projection.

Reprojection is one of the functions I incorporated into MAPC2MAPC.

It is straightforward to convert the Raster NOAA charts to 'Garmin Custom Maps' (with limitations on size) or to maps that can be used with many smartphone apps.

With power available on a boat the smartphone battery worry disappears.
