I have a bit of a situation. I was assigned a task to create a system that will take a KML file and update markers dynamically on a map. I'm currently generating the KML from a Wireshark Dissection and now need a way to take said data into a mapping tool. There are a few situations:
The PC that will be running the system will not have internet access, so I will need to cache de map data.
Each marker might move location so I need to erase said marker's previous location and update it with a new marker location. I do have a sequence ID I can identify it with, but I don't know how I'll update the new location.
It needs to be dynamically updated. A system will send data, my Wireshark Dissector will dissect the data and export it into a KML. This KML will need to be dynamically loaded into the system.
The basic idea in mind is like looking at Google Maps and watching your car move as it tracks your GPS location. But I need to make this tracking system work for a lot more targets than just one.
I'm sorry I currently have no foundation on where to start, but that's why I ask for your guidance. I've researched on ArcGIS, QGIS, Google Earth and Maps, but I haven't found a way to upload dynamically nor refresh the system.
Anything that could help me start finding a solution for this task will be appreciated.
Thank you for your time.
I had experience using leaflet js which allowed you to use bing map, google map, or opensource MapQuest to display mobile-track and car-tracking (for GM OnStar). I am also coding for kml to display flight-tracking on google earth now.
First, I am not sure it is possible or not :
you have a machine not connecting to internet
you want to use those map resource on internet
SO that I will assume that your machine can access internet. Then, there are many solutions.
You may try to see the simple tutorial on http://leafletjs.com/
You will have idea how to do it.
Plus, you have search for examples for Google earth (on which, I can display 3D tracking route).
Hope this help.
Other than map, see my sample to " Dynamic update data on Google Earth " in the following :
https://sites.google.com/site/canadadennischen888/home/kml/auto-refresh-3d-tracking
hope this help ....
(The following are copy from my link which talking about KML for 3D Google Earth. But I believe you can make it into 2D if you have to "not-use-google-earth".)

How to make a dynamic Auto refresh 3D Tracking :
prepare a RestFul service to generate KML file from DB
(sample as in https://sites.google.com/site/canadadennischen888/home/kml/3d-tracking)
My other jsp code will generate a KMZ file which has a link to my Restful service. KMZ file has onInterval ( as in the bottom)
Jsp web page allow user to download KMZ file.
When Google Earth open KMZ file, Google Earth will auto refresh to get new data from that Restful service
Everytime refreshing, server will send the latest update KML data with new data to GE.
KMZ sample:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2"
xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">

I'm trying to create a vCard containing the text below:
BEGIN:VCARD
VERSION:3.0
PHOTO;VALUE=uri:https://upload.wikimedia.org/wikipedia/commons/2/25/Intel_logo_%282006-2020%29.jpg
N:Raven;Test;;;
END:VCARD
according to this documentation (
screenshot of the part I'm talking about ) I tried base64 and it's working fine ( Contact app loads the image ) but in the URI situation it's not working ( Contact app does not load the image ),
To avoid making a large file, my goal is to have a url in my vCard.vcf file not a base64, I'm stuck understanding what's wrong with my vCard.
basically what I'm trying to make is a vCard containing a photo that gets fetched by the url given and shows the photo in contact app of whatever OS the user will open it on (Windows/Android/IOS/macOS).
I'm not using base64 because it makes my vCard file so big.
External urls are probably blocked by most programs, same as loading external images are blocked. It's a massive privacy concern.
Maybe hosting it on a service like Google Cloud would help, in that you can edit the CONTENT-TYPE and CACHE meta data attributes? It’s my novice understanding that smartphone OS is particularly wary of “unknown” file properties - probably for good reason.
While playing the game War Thunder if you use the address http://localhost:8111 you can access a website that shows the current parameters of your plane that you are flying.
I want to access this data and automatically export it into files. For example the power performance of the engine at certain heights.
I use beautiful soup and urllib to access the data. However I have no clue how to send the data from my game with it. Without that however the website does not show any data.
Does anyone have an idea how I can send this data with my request?
If you're writing your script in Python, you can use this module. Once you have the data, you can write out the data like so:
with open('logger.txt','a') as outFile:
outFile.writelines(data)
Obviously, it'll take more effort to get things working, but it's a good start.
I am trying to create a Shazam like service that works over the phone,
I was able to use Inspect Element to dig around and find an API call for WRIT FM.
I am trying to do the same for WKLH FM but I have not been able to find any references to any code that points to the currently playing song metadata.
The now playing page is here: http://player.listenlive.co/41851
It doesn't come up when doing View Page Source either,
Is there any tool I could use to pinpoint where the metadata is coming from? I need to be able to extract text in real time using a custom-made API so I can use that in my application (Asterisk PBX),
On the song history page, there IS some of this information available but it doesn't seem like it's offered in any predictable way which could be parsed: http://player.listenlive.co/41851/en/songhistory
Thanks!
I am trying to implement this function with ArcGIS Server JavaScript API:
I have a web map created by ArcGIS Online (or a web map created on the fly using JSON). Within the web map, I have a point feature layer (or MapServer layer). Initially the entire layer is shown on the map.
Now I am receiving a list of feature IDs received from another server, and I need to hide those points with the feature IDs on the map whilst maintaining the visibility of other points.
I am receiving the lists of feature IDs every 5 mins. Once a new set of IDs is received, I need to make the corresponding point invisible. If a previously hidden point is not included in the new list, they need to be turned back on again on the map.
Any ideas on how to startthis?
Thank you!!
Eric
It sounds to me that you are trying to implement an AVL system.
Anyway, the best way for receiving data for another server is using AJAX. Then, every time you receive new points, you'll need to clear the feature layer point and then to add the newest information from the server.
If you put your code in a fiddle, I'll help you.

I work with a company who outsources their website. I'm trying to retrieve data from the site without having to contact those who run it directly. The table data I'm trying to retrieve can be found here:
http://pointstreak.com/prostats/scoringleaders.html?leagueid=49&seasonid=5967
My methodology thus far has been to use google chrome's Developer Tools to find the source page, but when I filter under the network tab for XHL, only the info of the current games can be found. Is there anyway to scrape this data (I have no idea how to do that; any resources or direction would be appreciated) or another way to get it? Am I missing it in the developer tools?
If I had to contact those who run the website, what exactly should I ask for? I'm trying to get JSON data that I can easily turn into my own UITableViewController.
Thank you.
Just load the page source and parse the html.
