Powerapps, maps and polygons

Hi There,

 

i've built an app that displays road works.

it works fine, i've even managed to display polygons of the areas of this works thanks to this site.

 

my question is : is there a way to display at a high level zoom multiple polygons ?

 

"http://dev.virtualearth.net/REST/V1/Imagery/Map/Road/"&Gallery1.Selected.Latitude&","&Gallery1.Selected.Longitude&"/" & lbZoom.Value 
&"?mapSize=750,600&pp="&If(tglGPSActivé.Value;tiMaPosition.Text;"44.7777,-60.5555")&";82&drawCurve=p,64009900,FF009900,2;enc:"&Gallery1.Selected.encodage&"&key="& tiClé

 

in other words, can i add several enc: ?

 

thanks for your help.

Hi @GeekAlf_Pro :

I suggest you use a combination of concat and AddColumns.

I think this link will help you a lot:

This is possible through the new feature of Geo spatial features annoucned in Power Apps.

You can read about the preview details in the official blog: https://powerapps.microsoft.com/en-us/blog/new-geospatial-features-in-power-apps/

Hi @GeekAlf_Pro :

Do you want to add multiple polygons in a map?

Please try this code:

 

"http://dev.virtualearth.net/REST/V1/Imagery/Map/Road/"&Gallery1.Selected.Latitude&","&Gallery1.Selected.Longitude&"/" & lbZoom.Value 
&"?mapSize=750,600&pp="&If(tglGPSActivé.Value;tiMaPosition.Text;"44.7777,-60.5555")&";82
&drawCurve=p,64009900,FF009900,2;enc:"&Gallery1.Selected.encodage /*First polygon*/
&"&drawCurve=p,64009900,FF009900,2;enc:XXXXXX"/*Second polygon*/
&"&drawCurve=p,64009900,FF009900,2;enc:XXXXXX"/*Third polygon*/
&"&key="& tiClé

Hi @v-bofeng-msft , @Rahber ,

 

thanks both for your responses, i will study them closely !

 

have a nice day

Hi @v-bofeng-msft , @Rahber 

 

@Rahber i've asked my administrators to allow this experimentals features !

 

@v-bofeng-msft 

i've tried your suggest, and it works fine (i'll mark your reply as a solution) thanks again.

now, i'd like to grab from a collection the encoding value and display them on a map.

do you know if there is a way, with e.g a forall function, to pass the parameter to the url ?

 

/*ne garder que les encodage du jour */
ClearCollect(
    EncodageGlobalToday;
    Filter(
        listeTravaux;
        And(
            DateTimeValue(
                Text(
                    Date_x0020_de_x0020_fin;
                    "[$-fr-FR]dd/mm/yyyy"
                );
                "fr"
            ) >= Today();
            Today() > DateTimeValue(
                Text(
                    Date_x0020_de_x0020_début;
                    "[$-fr-FR]dd/mm/yyyy"
                );
                "fr"
            )
        )
    )
);;

 

 

to be clear with my EncodingGlobalToday collection, I would like to define a variable that will be enriched by each line of the collection

 

Thanks

Thanks @v-bofeng-msft,

 

it works very fine.

i've juste another little question

 

i've noticed that there is a limitation of 5 &Drawcurve parameters. i used FirstN function. so far so good.

but, when i display the map in powerapps, i only have one polygon returned, but if copy / paste the url generated in my browser, i've the five road worksMap in powerappsMap in powerapps

 

and the same url in a browser

 

url in a browserurl in a browser

 

My code is : 

 

"http://dev.virtualearth.net/REST/V1/Imagery/Map/Road/49.43594,1.09484" & "/" & lbZoom_1.Value & "?mapSize=2000,1000&pp=49.43594,1.09484;82" & Concat(
    AddColumns(
        FirstN(EncodageGlobalToday;5);
        "enc";
        "&drawCurve=p,7cfc0001,7cfc0001,2;enc:" & encodage 
    );
    enc;
    ""
) & "&key=" & tiClé

 

and the restitution of the code is 

 

 

http://dev.virtualearth.net/REST/V1/Imagery/Map/Road/49.43594,1.09484/15?mapSize=2000,1000&pp=49.43594,1.09484;82&drawCurve=p,7cfc0001,7cfc0001,2;enc:extlHwwrEvBiL{@cW|CqCfBhIbExAjDaDGdIyDjCsDbHoCnK&drawCurve=p,7cfc0001,7cfc0001,2;enc:q|xlHaevEpAwKpBkHrC_HhFdA}Jf`@kBbHxDvMuEpCaBgQ&drawCurve=p,7cfc0001,7cfc0001,2;enc:exrlHc}rEcAcFrBoBrAfF??&drawCurve=p,7cfc0001,7cfc0001,2;enc:kjwlHoczE]mUzE_R~OEt@`j@??uItD??&drawCurve=p,7cfc0001,7cfc0001,2;enc:_yqlHufsEoF_JkGsJgEeEuK`@}GrBaB|A[w@xGyE~F{@lNGzPz\|OpTu@z@&key=PutYourOwnKey

 

 

hi,

 

it's even stranger.

Since i only had 1 polygon returned, i set the number in the firstN function to 1, then 2 and so on.

it is as if the function returns only one line of the collection... instead of the numbers of lines

 

and last but not least, with the parameter 2, i've.... 2 polygons.

it drives me crazy...

Hello,

 

i keep on looking for a solution.

i've tried with google maps, but it seems to be the same issue.

the url's displayed in a browser shows the polygons but not in Powerapps.

has anybody an idea ?

a transparency parameter ?
