LabGIS for using carthographic maps in LabVIEW

Recommended Posts

Hi everyone,

I was forced to insert google (or equivalent) maps in a project and, for some time, I used Mohammad Garousi version (that I found the most complete version freely available on the web). It uses the GMap.NET dlls. After some time I noticed a recurring random issue at dll level, after which a red cross appears in the .net container without any chance to correct or avoid the error.

After some time I decided to create a new map container that might solve the issue. I decided to use a picture instead of the .net container. I was able to add new functions too, like creating a route, customize its behavior (such as changing the route color to spectrum), or add another image moving with map position or zoom change and so over.

The result is attached below.

This is a full-working example that can be studied or modified at will, but still a demo and not a library or final release.

User can move map dragging it inside the picture, can zoom with the slider and so on. Coordinates and cursor positions are updated live any time the cursor is in the picture area.

You can draw a route enabling the draw button. Remember to set it off when drawing is over.

You can add a third party image (the default one is a drone image) in the picture 0,0 position. You can easily customize the default position acting on the block diagram code. Any time you set the image button to on, the image will be placed to the 0,0 position, recalculating its latitude-longitude coordinates.

You can dynamically change map representation, route color or zoom.

 

I hope this example can be useful for those who need a more stable GIS representation. If any issues are discovered, please contact me.

Bye

 

Flavio

      I am implementing a TCP connection between MyRio(client) and Python(server). The goal is to send data from the server to the client, perform some calculations, and send the result to the server. I need to keep changing the data being sent to the client. I noticed the first data works fine and the result returned to the server, but the client could not read subsequent data. I debugged and was able to detect that the error is coming from the first read function is the "Reading values subvi"  but I don't know how to correct it. How do I go about it?
      I have attached the files below.

      The Threshold Hysteresis VI allows an input (for example, a sensor) to drift out of an inner limit without generating an invalid flag, but if it drifts outside an outer limit it then becomes invalid. For the reverse, when the input crosses back into the outer limit it remains invalid until the value falls inside the inner limit.
      For simplicity, only one input parameter is provided for both the inner & outer limits, and is negated for the lower limit, as generally tolerance limits are equidistant from the nominal.

      Hello I am quite new to labview and I have some questions regarding labview. We have came up with a simulation build in labview as shown in the folder. However, we will be making use of Myrio to connect current and voltage sensors to send the data to labview when labview is running. We are currently having difficulties trying to search if it is possible to send the wave files and the popout messages ( messagebox.vi and Player2Wins.vi) to NI Dashboard for Labview in Ipad by using myrio. Is it possible for myrio to store wave files and the additional VIs and sending these to NI Dashboard for Labview? 
       
      Otherwise, it is possible for Labview to send the entire program.vi, messagebox.vi and Player2Wins.vi to cloud and people are able to see the GUI in program.vi remotely? ( We have found information like Labview web services etc. We hope that people are able to view our GUI and press the " Press start" button as well as closing the popout messages in a website not from our local network). 
       
      I sincerely apologize if what I am asking does not make sense to people who are reading this. I hope that someone will help me with this as it is very difficult for me to do and I need some guidance from people who are familiar with these. Thanks for taking your time to read and your reply.
