Hello, today we shall show you how to configure BGMountains with GaiaGPS
or any other mapping service which uses tiles and available online
First you will need to have an account in GaiaGPS. In our case, we've made it with our Facebook account
From our profile, we select Map Sources
Then we go to Import an External Map Source
From this page, you can read more about the importing process.
We click on this link here.
We are going to create so called TileJSON file.
Our next step would be to generate our TileJSON file.
We will do that with a tool called TileJSON Tester
You will need to pass it the needed parameters, and it will generate you the needed TileJSON
In order to generate the file, we will need to acquire the link for the mapping service
We open the BG Mountains site, where the mapping is generated
Then we select the layer that we want to use
In our case, we've already configured BGMountains, so now we will demonstrate it how to do it with OSMap
We need to find the URL which is generated for each tile
For this purpose, we use Developer Tools of the browser (by default, it is accessible by pressing the F12 button)
We find the generated URL and copy it into the computer's memory.
Our next step would be to place the URL in the respective TileJSON Tester field.
We will need to change some parameters to be dynamic
These are the parameters for zoom level, longitude and latitude
In order to find it, you can simply zoom into the map and inspect the newly generated URL
In our case, this would be the first parameter - therefore that would be the Z index
Resectively, that would be Z, then Y, then X
In order to test the result, we click on the Update Map button
Obviously, these parameters are not correct.
Let's fix them.
That could be X and then Y
We update the map again, and we could see that it looks as expected now.
We have OSMap
Our next step would be to name our map layer, give it a description, and finally a source (attribution)
All is generated dynamically, so let's copy the result and save it on our Desktop via Notepad / Notepad++ in JSON format.
Our next step would be to upload the TileJSON file.
We already have our map, we could make it public for others to use, or to check if it has synced to our mobile phone
Here we can check the sync status
Let's switch to the mobile phone
We are already operating with our phone. Let's start GaiaGPS
Now we shall see if the map has correctly synced
From the upper right corner, we click on the layers icon, which brings the layers menu.
From here we could change our layers
Let's switch to OSMap layer and insect if we get the expected results
It looks fine for now
Now let's switch back to BGMountains so we ensure that we could use both layers.
Our next step would be to update the map tiles. This is done via Map Downloads -> Check Downloads
Now let's show how we could prepare maps for offline usega.
Click on the Circle with a Plus sign in the upper right corner (next to the Layers icon), then click on Download Map
Now by using the red rectangle, we select the area which we would like to download the tiles from for offline usage
I've already downloaded some
Now I select Strandja Mountain, because I have an upcoming expedtion there.
I click the Save button and type a name of the area.
And we are done, the app starts to download the tiles in the selected area for offline usage.
When the download completes, I will be able to use the map offline.
