12/9/2011 Traffic Cams, part 2

A quick follow-up on yesterday’s “Traffic Cams” post. I am trying to keep my code-writing “skills” buried, so I like clicking/double-clicking/cut-and-paste. I made a spreadsheet of the four traffic cams, but I needed their Latitude/Longitude coordinates (or so I thought).

To get the Latitude/Longitude, I open ArcGIS Online
ArcGIS Online
(note: you do not need to Sign In for this feature)

Click Map, then change the BasemapBasemap to Bing Maps Road. Zoom-in on the area north of Washington, DC. Click the Measure button, then click the Location tool.

Position your cursor over the intersection of I-495 and River Rd and Latitude/Longitude appear on the fly (work off the Camera Locations map identified in yesterday’s blog):

Fill in the spreadsheet for the four cameras, and copy-and-paste their urls:

Highlight the 20 cells and Save As TrafficCams.csv
In ArcGIS Online, close the Measure box. Click the Add button, then click Add Layer from File:

Go choose the csv file, then click the Import Layer button. The file is uploaded, and the program determines the locations from the Latitude/Longitude fields, and zooms appropriately:

Change the symbols by clicking the little arrow in the Contents and going down and selecting Change Symbols:

Then click the Change Symbol button. In the Change Symbol popup window, I like the camera in the People Places font:

Select it, click Apply, click Done, and click the X to close the Change Symbols section:

When you click on a camera, you get its info window:


The program is smart enough to include the url field – click on More info and the traffic cam appears in a new tab (if you right-click on More info, you can select Open link in new window, allowing you to have multiple windows open at the same time).

Additionally, I can Embed in Website or Make a Web Application – sounds like tomorrow’s blog!
