Come creare una mappa JNX con le ortofoto di Google Earth.
In many after reading the previous post where he spoke of the release of the maps of JNX Birdseye (who had lost the location here), have written to me asking if I could explain a simple procedure that would allow him to create a map Birdseye staff.
So I welcome the invitation and I'll show you a simple method, where you do not go mad with various programs or puzzling until the merger, but just follow these simple instructions.
Do 'for granted that you have already taken steps to patch the firmware of your GPS as explained above and then passes directly to how to create the map.
programs we will use for this procedure are:
Creator Atlas Mobile, available here and Mobat2jnx downloaded here.
program as you will notice is divided into two windows, left one with the settings and controls, and right to display the map.
select from the drop-down menu in the "Map source" map the source from which we want to take our pictures. For example Google Earth.
Well, now nellafinestra the map looking for the area that interests us and when we found, tenendopremuto the mouse select the area of \u200b\u200binterest.
We get a red box of nostraselezione, the mouse only allows the selection of the area, if by chance dovetemuovervi window you must use the arrow keys on the keyboard.
In 'image was selected as the area of \u200b\u200bMonte Castelberto.
back in the left window pane we have the "zoom levels.
along these If the maximum is 20 disponibileche detail to gradually decrease.
Quidobbiamo select the zoom level that we need, whereas in the case of Google Earth images taken from different levels of zoom are enabled in the browser as reported quisotto:
Livello 20: appare allo zoom di 5m ma l’immagine è sfuocata.
Livello 19 : appareallo zoom di 12m, a 8m e 5m sfuoca.
Livello 18 : appare a 20m, a 12m la visibilità è buonaa zoom inferiore sfuoca.
Livello 17 : appare a a 50m, buono dettaglio a 30m e20m da 12m in poi sfuoca.
Livello 16 : apparea 80m, sufficiente la qualità a 50m azoom inferiore sfuoca.
Livello 15 :appare a 200m e resta good up to 120m, the 80m is sufficient qulità poisfuoca.
Level 14: appears at 300m and is good at 200m, 120m already a blur.
Level 13: appears at 800m, 500m to good at lower zoom blur.
Level 12: appears at 1.2 km, 800m blur.
notatebene If you will be just below shows the number of tiles that verrannoscaricate.
Keep presenteche map JNX damassimo 50,000 tiles can be made, and the navigator, memory permitting, accepts JNX than 199 maps.
A consideration on the level of zoom.
A consideration on the level of zoom.
leortofoto For Google Earth satellite, in my personal opinion, I find that the levels 19 and 20 are virtually unusable because leimmagini already delivered are blurred.
level 18 would give itself a buondettaglio but in addition to increasing significantly the number of tiles, does not offer more than the livello17 which I think is the best choice, since it unbuon detail the levels of zoom 50m , 30m, 20m.
16E good level to get good images to zoom 80m, while a level 15 or 14 are an obvious choice for a good 120m and 200m in detail.
inbase Do you see the display of your GPS and what level of zoom worked normally percapire what are the best choices on my 62S for mappamultilivello 3 or 4 levels, the choices are 13,15,17, or 13.14 , 16.17.
In Layersettings fondamentalespecificare instead is the size of individual pieces, although they seem not to riscontranoproblemi with tiles larger is better to set these parameters a256px to 256px.
In Atlassetting set the tile storage format OSMTracker
inAtlas After the content item name enter the name you want and then clicchiamosu "Add selection"
The window will bring our choice indicated ilivelli zoom selected.
Well at this point click on the button right below:
start so ilprocesso Creation
After he resides within the program folder Mobac dentrola Atlases we even made our very folder from "nome_data_ora" where you downloaded the map.
Within it, in the 'Google Earth "we have the folders of our downloaded zoom levels, in this case 14, 17, 19.
Per comodità vostra vi suggerisco di copiarvi le cartelledegli zoom in una destinazione più comoda, ad esempio nella root di C:\ possiamo creareuna cartella MiaMappaJnx , questo perchéil comando che invoca Mobat2jnx bisogna lanciarlo da un Prompt del Dos e vi verràquindi più semplice in seguito specificarlo.
Ora apriamoci un Prompt dei comandi e andiamo all’internodella cartella dove è stato installato Mobat2JNX.
Il comando da lanciare sarà il seguente:
mobat2jnx \u0026lt;folder> \u0026lt;options>
where \u0026lt;folder> is the location where our resident livellidi zoom, if you have made will be shown as C: \\ MiaMappaJnx.
E 'can also specify the quality of jpeg, perdefault is 4, the highest quality is the minimum 5 1.
Well now launching the command as you see below:
mobat2jnxC: \\ MiaMappaJnx-jpeg5
Mobat2jnx recognize how many levels within and proceed zoompresenti allascrittura of creating the map tiles are JNX.
NB: The maximum zoom levels that are running JNX 5.
When completed, we will find in our directory MiaMappaJnx also our map Birdseye just creatacol name JNX.jnx
rename it at will, , there is at this copiarloall'interno point that the GPS folder \\ GARMIN \\ Birdseye.
