Oruxmaps Dem Files Download
Zelda Diomede
They are files that contain the altitude of a grid of points in a certain area of the Earth. They allow you to know the altitude of any point of the map, without needing to be at that point, where you would get it from the GPS.
These files are used by OruxMaps for various functions:
thank you for a file! It seems that José ( developer of Orux ) use here similar system as to DB map files. So every layer has defined own configuration with calibration parameters, that needs to be used for correct placing of the map.
Hi Massimo,
the GPS accuracy may vary from phone to phone. But on my phones/OruxMaps i use only DEM files, with the setting activated, show in your screenshot.
And, if available in the region, i use the more accurate DEM files from Sonny: -forums/topic/precise-lidar-elevation-files-for-use-with-openandromaps-locus-orux
The following files (for the OruxMaps application) are for use on an Android smart phone or tablet with GPS. They allow informed hill roaming with all entrances, some heavily vegetated depressions and surveyed cave passage centre lines shown on the screen map. The app and data has been tested on various devices.
Vector maps (.map) should be installed on the sd card in the folder /sdcard/oruxmaps/mapfiles. The vector maps now come with additional style files that should be also installed. You can also create subfolders to organize the maps. In the map dialog you can then go to offline maps and chose you map.
Ready to go topographic maps for outdoor activities are available here 4UMaps DownloadSimply copy the files into the /oruxmaps/mapfiles folder on the sd card, and select offline map from the main menu.
If you want to see all of your waypoints, you can go to Waypoint >Manage. From this page you can change the properties, delete and export the waypoint. To see all of your waypoints in map, select the waypoints and go to show in map (1) and if you want to export your waypoints press Export (2). All of your exported waypoints will be stored in internal storage (by the default it stored in oruxmaps/geocaches).
1. Offline map location on phone
For the new K3 App Offline map development, would it be possible to use the same map location as Oruxmaps uses?
Because Oruxmaps und Kurviger using the same maps, and Orux stores the map in Android 11+ in Android folder /android/data/com.oruxmapsDonate/files/oruxmaps/mapfiles an its not possible to change it from android folder, just possible to add another subfolder.
With the K2 app I can not access the /android/data folder while selecting the map. I would be nice this would be possible to safe storage space on the phone.
We'll take two approaches. The first is the 'easy' option in that you don't need to configure too many options on your device to get things up and running. If you want a little more control over what goes where, then you might look at the second approach. This might be the case, for example, if you have limited internal memory on the device and want - or need - to put the (large) map files onto a microSD card. You may also wish to install additional themes, or 'skins'. Essentially, you'll need an app, a map and at least one theme...
If you're going to try this yourself, then you need to be comfortable navigating around your phone's file system, copying/moving files and so on. You will also need to be able to unpack a zipped file on your PC and transfer files to your phone or other device.
There are questions as to where you want to install the map files, which can be quite large. If you have an SD card, then that will likely be the best option. If so, then create a folder on it called, say, Maps. So, in general, the app is on the internal memory and the map(s) will be on the card. If you don't have a card then you'll need to create the directory in another location. Wherever it is, you'll now need to search through the app's settings so that you can set the map folder location to the one you've just created. We'll explain that process shortly.
1. swipe right from the top left of the screen
2. tap the 'cogwheel' icon at the Maps section
3. tap the Maps Directory section at the top and navigate your file system (not always intuitive!) to locate the Maps directory, or whatever you called it
4. tap the OK button to set it as the new preferred option
5. repeat steps 1-4 to set the DEM files directory
You now need to install some themes. To make life a bit easier, we've prepared the files you need for each of the themes into three .ZIP files. You've done a lot of work to get this far so I'd suggest installing all three and trying each one. If you don't like a particular theme then just delete the files and it won't appear in the list.
To install them, you can download them to your PC, unzip the files and then copy them across to your Android device or you can download the zipped files to your device and unzip them there. So, for example, to use the first method:
1. on your PC download the three files to a temporary location
2. unzip each in turn to that location, or another of your choice
3. copy the files to the Themes directory on your device, making sure to preserve the file structure - subdirectories and so on
4. restart OruxMaps and it should now list the different themes (see 11 & 12 in the previous section)
5. you can either save the zipped files somewhere or just delete them entirely
You'll probably also have come across options to show hill shading and/or 3D map views. This process requires downloading additional DEM files. They will be in .HGT or .HDR format and it is these files that will go into the DEM folder that you created earlier if you use those features.
Tracks & routes are essentially the same in that both can be represented as collections of waypoints in GPX files. It may be useful, however, to consider a track as being a record of a journey that you, or someone else, has already completed. A route, on the other hand might be thought of as a journey that has yet to be undertaken. This is not a strict definition, but you may gain a better understanding if we consider the sort of information that the route or track file contains.
Firstly, GPX files are simply text files and you can open them in any text editor. Other than the header information at the start of the file, you'll see that the track or route is just a collection of waypoints. A waypoint, at its most basic, will clearly contain the coordinates of the point in question; in other words, the latitude and longitude. These two figures may appear in a number of different formats but they all specify the location.
You'll probably have come across an option in Orux to offer hillshading to create a 3D image of the landscape. This, however, requires that Orux downloads DEM files which contain a grid of elevation data. Orux can do this on the fly for the area that you're looking at but, of course, you need to have a network connection to do this; not always convenient if you're out and about.
1. navigate to _org3.htm
and choose the areas that you wish to download
2. clicking any one of the grid 'squares' will download a zipped DEM file for that area - about 9 or so will cover most of the UK
3. unzip the file to a suitable location - you should find another folder with maybe 18 .HGT files in it
4. copy the individual .HGT files into your DEM directory - do not put them in a subfolder of it.
5. repeat for as many zipped files as you wish
Locus maps has been mentioned as well as OruxMaps. Both apps have a wealth of features and both have pros and cons. The good news is that if you want to use both apps then you only need to install one version of any particular map as it can be used by both apps if you tell each one where the map is located. There seem to be a few differences in their use of themes, however, and it might be best to keep separate copies of those files for each app.
Starting with Cartograph 2.0.7 Oruxmaps SQLite raster maps are supported. Oruxmaps SQLite maps consist of two files, the map database "OruxMapsImages.db" and the map control file "*.xml". On iOS and Windows Phone both files have to be copied into the Cartograph map's directory (using the Wifi uploader or iTunes file sharing). The .db file has to be the same name as the .xml file. For instance if the xml file is named "MyMap.xml" then the db file's name must be "MyMap.db".
With the macOS App Store version of the Cartograph app both files have to be located in the user's downloads folder (due to sandbox restrictions). The download folder is located under "/Users/your_user_name/Downloads".
I have big plans to create a nice web service that allows anyone to download anoffline map file for any trail of his or her choosing. Since I am a terribleprocrastinator (or a great one), I decided to start by adding some value,instead of planning too big. So here are some map files I already made, for yourpleasure:
I am experiencing upload problems, but cannot say since when.The recorded file is on my Sony Xperia Go smartphone at /sdcard/gpx as filename.gpxWhen I connect the smartphone to my lapto under Win7, the recently recorded file is not visible at all. Hence I cannot browse the smartphone's filesystem to get it uploaded to OSM.
So check where you are saving your files. It seems that many apps will say saving in external storage, but actually save in the sdcard directory. It is worth getting a file explorer on the phone so you can see where files actually are - ES File Explorer is a good free option.
Using my android I record trace on a third party mapping app and the track or waypoints can be emailed. I sent them to myself, open the mail on my Win PC and the GPXes get saved in downloads. Using Potlatch2 ( which i think you use) I select backgrounds and Vector files, browse to downloads and select the track or waypoints and the track or waypoints should be seen in the edit screen.
