I was looking around the internet and couldn't find a perfect algorithm for this particular problem: Our customer have a set of points and weight data along with each point as can be demonstrated by this image: Of which, we have a GIS program that could generate a "heightmap" or a sort of terrain data from these points and their weig...
I want to create some heat-map style tiles to overlay over our base maps using Open Layers. Basically, I want to divide some some bounding box into a grid, and display each square of the grid using a different color based on how many points of a sample fall within that grid square. The technologies involved are C#, OpenLayers, SQL Serv...
Are there any JavaScript libraries out there that allow you to create heatmaps using in-browser graphic rendering features such as <canvas> or SVG? I know about HeatMapAPI.com, but their heat maps are generated on the server side. I think that in the era of <canvas> element we don't need that anymore! If there is nothing like this yet,...
Is there a way to create a heat map in google earth, so areas with higher values (of some specified parameter, such as population) appear as hotspots? ...
(I hope this is a valid question) As I stated in my title, I'm looking for a fairly easy to moderately easy idea for some sort of online raster analysis map. I'm familiar with ESRI and their really awesome API, as I'm hoping to tackle something on that front. I'm also open to using the mapstraction lib. Does anyone have any ideas f...
I want to create a simple infographic in python. Matplotlib seems to have a lot of features but nothing that covers off my simple heatmap grid example. The infographic is a simple 5 x 5 grid with numbers inside ranging from 0 to 1. The grid squares would then be coloured in 0=white 1=blue 0.5 being a pale blue. Matplotlib could probabl...
Hi All! I’m at a very basic level with Flex and with programming in general. I am working on a project where I have data in an Excel (.csv) format, it’s a large Excel plot/matrix where each cell has a temperature number. I want to import this matrix into Flex somehow, or parse the data in Flex, so that this matrix turns into an interact...
I am trying to reproduce the heatmap effect Bungie uses to show kills/deaths on specific halo 3 maps using PHP and GD. (Example: http://www.bungie.net/stats/halo3/heatmapstats.aspx?player=gatts007 - pick a map like "Guardian" for a better example.) I have all the data and background map images from my game, but I am having trouble comi...
I am interested in creating a heat map of the stock market using internal data, in much the same way as the following site: http://www.smartmoney.com/map-of-the-market/ We have all the data necessary to do so, as well as a C#/ASP.NET front end and a C#/SQL Server 2005 back end. Can anyone recommend any resources for creating this type ...
I want to creata a heatmap (density map) on images. The examples like the one in http://www.heatmapapi.com/Sample%5FGoogle.aspx are good examples of what I try to do. Is there a GWT way of achieving this? Or any good (flash or js) solution you can suggest (other then the ones mentioned http://stackoverflow.com/questions/357721/heatmap-t...
SpatialKey generates some really nice looking heatmaps, and we're looking into what's involved in doing this for an internal project to visualize large amounts of points. I'm looking for feedback on some ideas on where to get started (and it's just a really interesting problem). We know that they're using Flash, and from what we can t...
I have a list of values each with latitude and longitude. I'm looking to create a translucent heatmap image to overlay on Google Maps. I know there are server side and flash based solutions already, but I want to build this in javascript using the canvas tag. However, I can't seem to find a concise description of the algorithm used to...
I am looking to build a static KML (Google Earth markup) file which displays a heatmap-style rendering of a few given data sets in the form of [lat, lon, density] tuples. A very straightforward data set I have is for population density. My requirements are: must be able to feed in data for a given lat, lon must be able to specific th...
Are there any tools out there, for MFC apps in particular, which can be used to gather data on how users use dialogs... of primary interest is which controls are accessed most often. I'd guess one could write something that would plug into an existing dialog without too much fuss, but perhaps something (preferably free) already exists t...
I want to convince some clients to use MapServer and OpenLayers. Please can anyone suggest attractive websites to show off the possiblities! The clients will be impressed by: A density map (otherwise known as a heat map, colour-shaded grid coverage, contour plot...). The ability for the user to download the underlying data for the ...
I'd like to create a Google Visualization API intensity/heat map based on UK counties. To do this, it appears that I need to use a custom KML/KMZ file that contains the county mapping data (which I've located). Could anyone provide me with a sample of how I can display an intensity map based on a KMZ file? I know how to display Google ...
The new FusionTablesLayer in Google Maps API version 3 has an option to display as a heatmap instead of points. Here's the example. Is there a way to get the heat map display without using Fusion Tables (but still using the Google Maps API)? I already have my data in my own PostgreSQL/Postgis database. Having Google do the heatmap a pref...
Hi stackoverflow-pros, I need your help again :) I wrote an R script, that generates a heatmap out of a given tab-seperated txt or xls file. At the moment, I delete all columns I don't want to have in the heatmap by hand in the xls file. Now I want to automatize it, but I don't know how :( The interesting columns all start the same i...
Using GDI+ I've made a heatmap bmp and I'd like to superimpose it on top of my bmp map. I've saved the two bmps to disk, and they look good, I just need a way to put them together. Is there any way to do this, perhaps using the Graphics object? How is transparency/alpa involved? I'm very new to GDI programming so please be as specifi...
I'm trying to plot heatmap in ggplot2 using csv data following casbon's solution in http://biostar.stackexchange.com/questions/921/how-to-draw-a-csv-data-file-as-a-heatmap-using-numpy-and-matplotlib the problem is x-label try to re-sort itself. For example, if I swap label COG0002 and COG0001 in that example data, the x-label still c...
