Another Google Maps Extension

[Alexander_Thor]

UPDATE 2013-03-23

It's great to see the support from the community around mapping! This thread has been great to follow and lots of fun contributions has been added.

It has however become quite crowded with different versions being discussed and it's hard to find any useful information anymore.

So I have decided to kill off this thread and at the same time I have updated the extensions and split them into 3 parts with each extension having it's own thread.

Hopefully this will make it a bit easier to find information, ask questions and share new implementions of the extension between each other.

Google Maps - Cluster

Google Maps - Marker

Google Maps - Heatmap (New!)

If there is interest for a more collaborative development let me know and I will host the extensions up on Git.

Sure, you could use google maps with other plugins and integrate that into QlikView.

However this extension and thread focuses on the cluster plugin.

If you want to use the routing box plugin together with QlikView you would have to create your own extension to handle that. The base code in this extension, or any other Google Maps extensions, should get you started. Good luck!

Great work on this subject, Alexander and guys!

I hve been trying to find a way to turn coordinates that come in this format: (xx° xx' xx" N), to that one:  -xx,xxxxx, no luack so far,

any ideas?

Thank you!

Qouting Wikipedia

Conversion from MinDec to Decimal Degree

Given a MinDec (Degrees, Minutes, Decimal Minutes) coordinate such as 40°26.7717N, 79°56.93172W, convert it to a number of decimal degrees using the following method (for example for 79°56.93172W):

1. The integer number of degrees is the same (79)
2. The decimal degrees is the decimal minutes divided by 60 (56.93172/60 = 0.948862)
3. Add the two together (79 + 0.948862 = 79.948862)
4. Negate the value if it is South or West (in this case, West, so -79.948862)

Attached is a sample qvw to help you with the conversion.

Hi,

I am opening Google map cluster but still get a stack overflow error. How can I address this?

Also, how can I plot data points on my map corresponding to certian latitude and longitude values? Can I only do this with google cluster or can I also do it with the normal Google maps?

Thanks.

Hi Alexander,

I have gone through ur extensions and they are very helpful.

i have few questions with Heat maps.

i want to use the heat maps is there a way that i can pop up the labels when i hover on the bubble.

i want to display like 5 things example, state,city, street address,revenue.

i am using the heatmaps not figuring out how to popup the labels..

Thanks

Julie,

Thank you for posting this sample app - using the image plotting. It gave me some cool ideas for our call centers.

Hi Alexander,

Its map is divided by states rather than by country?

In google maps it was divided by a given state could harness and use the states as a filter.

Thanks.

Hi Alexander,

  I have downloaded your extension for heat map and it is working fine

  how can i show the heat map for US regions?

[#11]

I created duplicates on each data point in order to show all of them as clusters on a map regardless on whether you zoomed in on a  point or not, but that was not successful. I additionally altered the extension property's max zoom, but I am still able to see a few clusters. Is there part of the extension that disables duplicates? Any ideas of how to edit the extension in order to display all data points as clusters rather than as markers? I edited the markers so they're defined as the sum of total sales in a given area rather than the count of the markers, so the clustering is ideal for a US map view.
