Hi-

I'm putting together a map of a peer to peer computer network (still a work in progress). I was given lat-long locations with the number of hits on the network, per location. The customer wants more than a gradation of color distinguishing the number of hits on the network. I had envisioned a DEM using the number of hits for elevation. However I have been unsuccessful in making what I envisioned. I'm using ArcInfo with 3D Analyst, I also have Illustrator and Photoshop. I have made a TIN, however it is very awkward due to the data points. Are there any suggestions on ways to show this data? Thank you

Tanya

Hi Tanya - that sounds like an interesting thing you are working on.

What is the message that you/client wants to communicate?

A DEM or TIN would be very odd, then you would interpolate hits in the spaces inbetween your computers. The density of nodes on the network would also be relevant information, wouldn't it?

If you are not satisfied with the bars (which looks ok to me) you might want to look into proportional circles or squares (or spheres).

Could it also be that (physical) space is of less relevance, and it should more be organised in some other space?

If it is peer-to-peer - do you have any information on the relationship between the nodes (how they are connected, traffic), and would that be relevant?

This is a very cool project that I'm working on for a forensic lab. I have received a spreadsheet with 3 columns Latitude, Longitude, and Numbers (number of hits). I'm not getting anymore info than I need to make the map they want! They want to show the number of hits per location, I have no info on how the network is actually connected. So, no interpolation or density info is relevant to this map.

I wanted a graph-like map that was more of a continuous graph, like a DEM. From what I envisioned, what I have looks boring!

Hi Tanya,

Have you thought of using interpolation calculations to "smooth" out the data between your data points? While this would create potentially meaningless data between your data points, it might improve your map aesthetically. To keep the data accurate, you could label the data locations with the values they represent. It may look a bit better than having individual "data sticks" poking out of Maine and you would have to make sure that the 3-D effect you are using does not hide any of the data (no overlap of data points like you have in your current map), meaning you may have to alter your angle of elevation to a more vertical orientation (but not totally vertical).

Hope this helps.

I'd go with what you have but maybe graduate the color scheme along some natural breaks.

How about a proportional circle/symbol where the size is proportional to the number of hits. I just think the concentration of the data means the vertical bars overlap a bit too much.

Tanya,

I think what you have is good. The visual would be helped quite a bit if you used a more generalized coastline for your state/county boundaries.

New member here,

Just thought I would add a couple of my thoughts. I like what you have started with but I agree the coast of Maine has too much detail for this scale. Have you tried to classify the data by the number of hits? You can then use a graduated color scheme or spectrum, increase the size of the data cell to be a little thicker and try making a little transparent, about 20%. I think I would like to see it viewed a little more North-South also.

Just my 2 cents. :)

Mike

Rich,
Great idea, I think more generalized boundaries would work much better too, especially the coast. Thank you
