how to color parts in google map

[wewtalaga]

Good day!

I want to ask how can I color some parts of the Google Map.

I'm a bit of a beginner in LabVIEW (still learning the ropes) that's why I searched about putting a google map in LabVIEW and I found some. The question is, how can I add colors to them? In a specific place? Not exactly a pure color but just a shade to them?

Here's what I'm planning to do.

That's the Google Map of NCR (some place here in the Philippines) and I'm planning to add colors to some parts. How can I do it?

 

Thank you very very much for the help.

Have you tried doing the same thing as changing the color in an image, but would use the Hilite Color VI instead of replacing with green?

LabVIEW is just the host.

 

You need to create a KML file then get Google Maps to load it.

I tried but I got confused for a bit so I erased it. So I tried changing a color of an image by replacing a new color (example, looking for a color green and changing all green to white) but I'm still not sure if I'm on the right track.

I looked at the link you said and I have a question. If I'm going to make a KML file to load it on Google Map, will the coloring part be done through the map's coordinates?

Check out the LabView <-> google maps code on the code repository. It translates LV variants to Google maps JSON objects, and sends them via web socket to a browser. You can easily draw a polygon wherever you want with those VIs.

Thank you very much. I will try it and post the results here.

I could not open the VI properly. It has some errors where subVIs are missing.

Not sure what you are asking here, but KML has the ability to define the colour of a polygon (or line). The polygon is defined by map coordinates 

 

Here's a simple example that I found by Googling that enables you to turn on and off a coloured KML overlay.

Okay okay. I will check the link. Actually, I searched about KML and I found some sites on how to make them.

Thank you! I will post here the results soon.

You need few packages, OpenG and JSON Labview, both available from the code repository here, or better yet, via the VIPM.

I made a KML file. How can I put it in Google Map and put it in LabVIEW? Should I download the packages you mentioned?

You can use that software if you are using Google Earth (never used it, so don't know if it works or not). But if you are using Google Maps from a web browser as an activeX (or.NET) component in LabVIEW it's even easier.

Log in to Google Maps with your google account. Click on My Places and that will take you to a page where you can create maps.

Create a new map, add your KML overlay file and then just point your LabvIEW thing (browser?) to that map.

How can I put the browser to the LabVIEW? Is there some kind of URL?

Well. You you won't be able to use Google Maps without a lot more experience with web applications and JavaScript.

This is the easy way, but you will have difficulty updating the map, online, programmatically from you application..

You will have to download and install Google Earth instead of using Google Maps and use the library previously linked (if it works) to add your KML to the Google Earth interface.

Oh thank you. Actually, that is what I'm looking for, an easy way to show it. I also don't have plans on changing it from my VI. I just want to show the KML file. 

Thank you.

I'll post here if I have questions.

What if I'm planning to change the KML file shown. In what part of the path will I edit it?

You don't.

What I'm saying is I would like to replace the KML file I provided. In what part in the path below will I change?
