You will have as shown in the image above a file N48E001 When all tiles downloaded you will have many files in the folder So you’ve downloaded the tiles I called it franceDM (you will need to dezip them later or extract them while downloading) my folder and VRT file in my DEM folder Now I download these tiles to a folder that I had created in my DEM folder. Only one tile to be downloaded at a time. In my case France, so loads of tiles and you have to download them one at a time, doh. I then open from where you can download the DEM tiles for the area that you need. I have or created (I can’t remember which) a DEM folder Mine is in /home/trevor/qmapshack DEM folder in the QMapShack folder So how to use DEM filesįirstly in your QMapShack folder. So here is how to add DEM data to QMapShack, so that when you modify an existing GPX trace you don’t lose the elevation details. I finally realised that this was due to QMapShack not having the elevation info, and also realised that I would need to get this from somewhere, using DEM files. Either use Basecamp or drop the kmz in the custom map folder on you gps.After quite a while. Then change Draw Order to 50 and JPG quality to 100. Now copy the North, South, East, and West values from Google Earth to KMZFactory. Hit Select Image File and browse to the jpg you saved from QGIS. Leave the New Image Overlay dialog box open and go to the location tab. Change Show Lat/Long to Decimal Degrees Then hit OK. Select a location you will be able to find later. Select Raster from the Menu Toolbar at the top then select Conversion then Translate (Convert Format). It can be saved as a temporary file or you can change the name and location. In the window that opens you want to change the Target CRS to Project CRS which should be EPSG:4326. Select Raster from the Menu Toolbar at the top then select Projections then Warp (Reproject). Warp (Reproject) and convert to a GeoTIFF The image will probably stretch and distort a bit. Select EPSG:# located in the bottom right corner of the screen. Once it has been loaded you need to change the projection. You can simply drag and drop the downloaded geo-referenced image into QGIS. Use the link to download geo-referenced maps, Google another other source or geo-reference a regular map. Copy coordinates from Google Earth to KMZFactory, Save KMZ SOLVED? According to the Keyhole Markup Language docs, a KMZ file is just a ZIP file with a modified extension. Yesterday's hike would have been much more comforting if I could have seen exactly where I was at in the park.Įdit: I forgot about MapTiler, tried that as well! I am hoping someone can help me find a way to load custom maps into my GPS so that I can use maps like ones you find on State Park sites. No resizing, skewing, rotating pictures like in Google Earth. The thing I like about the GIS tutorials is that, to georeference, you just click on correlating points. I have seen many tutorials about using QGIS, ArcGIS, Qmapshack, etc.but nothing about how to make a custom map for a Garmin device. In the extracted files, I saw that the images were actually png files. So, I decided to try to unpack some kmz files I had made using Keka. Today, while reading around the web, I came across (maybe not the first time?) Garmin's General Guidelines for Creating Garmin Custom Maps. The 66st came out recently and I convinced myself that an updated unit would help (actually, just wanted something new). I followed many guides on Garmin and other places to do this, but none work. When I have loaded it into my 64s, it has never actually worked for me. Hello, I have tried for many years to take a State Parks PDF, load it into Google Earth, georeference it, and export it as a KMZ file.
