Thank you. can you also post the Value of the "self.geoResources" dictionary in the navigator class. and the list of files in the 'FrederiskbergCentre/positions' folder

[Katherine-NHansen]

I used your full code and just add my files, possibly my files are not correct in the positions, can I send them to you? In the first phase of your code ithe file.geojson works perfect, but the second one does not work, the errors follow.

[Katherine-NHansen]

I tell you that I am very excited and motivated to do this project, because I am a student of Artificial Intelligence (3-month course), and I find this project very interesting to develop, it would be interesting to work with the different plans of the place that I have chosen for this project, which is Frederiskberg Centret (4 floors). Do you think it is possible to continue developing it with this code? What do you recommend me?

[Katherine-NHansen]

I am amateur! :-)

[Fuenfgeld]

Hi
It would help me if you could share all your code in a github repository including the geojson files.

There are two things that you can do to develop the code further. You can add geojson files that add the internal map of the shopping center. Also, you can implement a real navigation system using a graph pathfinder algorithm (for example, https://en.wikipedia.org/wiki/Dijkstra%27s_algorithm)

the best way of learning programming is to program. Just continue to what you are doing :) .

[Katherine-NHansen]

Hello, what is your original name? :-)

I tell you to use your code and I made minimal changes, there is a file by GeoResources and path folders. Strange that I used the same files for the first part, however, the second part doesn't work.
What do you do to write the name of each polygon?
I draw the polygons, I am using an application called indoorAthlas where I can export the plans and make the drawings and then export each polygon to Geojson as .json and then I rename them With .geojson format

I'm very motivated to keep going :-)

I also added the files for two floors(Plan_G.png and plan1.png), but they are 4 floors.

Thank you for your support me, and I will be attentive to your comments.

I look forward to hearing from you.

Katherine.

[Fuenfgeld]

At the moment you only have two .geojeson resources in your repo w17.geojson and Haus22.geojson. And your code expect that the names of the file is w1.geojson and shop1.geojson. The folder with the geojsons must be named FrederiskbergCentre/positions. You need to understand this code better. it loads all the geojson resources

for root, dirs, files in os.walk('FrederiskbergCentre/positions'): for file in files: self.geoResources[file.split('.')[0]] = root+'/'+file

especially this dictionary is important, it contains all paths and outlines:
self.geoResources

my original name is really Maximilian Fünfgeld https://www.linkedin.com/in/fuenfgeld/

[Katherine-NHansen]

Hi Maximiliano,

Thanks for your help, you can see the code that I made the replacement, I looked at it in detail but the last part where the path connects to the store does not work. I've only stored a few of those files for testing.

https://github.com/Katherine-NHansen/FrederiskbergCentret/

Thanks you again,

I look forward to hearing from you.

Katherine.

[Fuenfgeld]

I checked your code. The problem is the naming of your geojson files. The naming convention Is that a path name is composed by the entrance (which is encoded by a letter) and the destination (which is encoded as a number). For example, w23 is the path from the west entrance to house 23. The naming conventions for the outline has to be House23.
If you change this naming convention in your files, you have do adept the code in the navigator class. The easiest way to fix your navigator is to change the names of the geojson files to match the conventions. You can still adapt the displayed strings in your selectors. I hope it helps.

[Katherine-NHansen]

All that was changed, but I will prove what you tell me :-) Thank you very much!

[Katherine-NHansen]

Hi Maximliano!

I have fixed the problem, it was access to the files, I had to put full access to the folder.

    for root, dirs, files in os.walk(r'C:/Users/Bruger/Desktop/FrederiskbergCentre/GeoResources'):  
        for file in files:
            self.geoResources[file.split('.')[0]] = root+'/'+file

Thank you very much for your time.
I have other questions:

-How do you trace or track the path to get from floor A to floor B (access to stairs and elevators)?

• What do you recommend me to show the maps (graphics) on a web page ?, Another student is confused in creating the web page to show the map.

I look forward to hearing from you.

I am very grateful for your help.

Katherine

[Katherine-NHansen]

Hi Maximiliano,

Could you suggest me how I can make the change from origin "w" to the same destination?
Everything is working very well , but making the change from a new origin (entrance) to the same destination shows me the same route of the previous selection, since I have 2 entrance.

Your help would be great, I am learning a lot!

Katherine.

[Fuenfgeld]

you have to change the navigator class . You need to remove the #. I deactivated the picking of an entrance because I was to lazy to draw all the possible paths.

[Katherine-NHansen]

Ok, I will try to do.... Thanks. Yes it is a lot job :-)

May I mention you in my document as part of the help you provide me? I appreciate your time.

thanks thanks Maximiliano :-)
