Figure 1. A map showing all gas and oil wells with core photographs for West Virginia available from the State Geological Survey.
Click on markers on the map or on API numbers in the table to obtain basic data about the wells and to link to photographs.
Photographs will open up in a new window or tab.
The map was generated using Google Maps API.
Code was adapted from that developed and provided by J. Detwiler (Detwiler 2009(a)).
Icon was obtained from CoolClips (CoolCLIPS 2009).
Icon shadow was generated at Google Map Custom Marker Maker (Powerhut 2009).
Data were obtained from the West Virginia Geological and Economic Survey (WVGES 2009).
Data were converted into an XML file using a tool developed and provided by J. Detwiler (Detwiler 2009(b)).
Overall Thoughts About the Lesson
For my project this week, the data set that I selected is from my work--I work at the West Virginia Geological and Economic Survey in Morgantown. The data set contains data for 11 gas and oil wells that have core photographs. I selected a rather small data set to keep the data, map, and sidebar manageable. However, I am confident that I would be able to apply everything that I learned this week to handle a larger data set. With respect to layout, I had a bit of trouble initially with my text showing up behind the map and sidebar. I tried several techniques to remedy the situation and the "div" tag seemed to work best. I am not quite sure that what I have done is totally robust because although I have specified the absolute position for the map, sidebar, and text below the map and I know the size of the map and sidebar; I do not know the exact size of my header information (page title, student name, and date). Maybe I missed something somewhere? I really like the Google Map Custom Marker Maker which I used to make the icon shadow. I tried to create the shadow manually but I was less than thrilled with my results so, I'll just stick with the marker maker in the future. One question that I have as a result of the project is--is there a way to do scale-dependent rendering with Google Maps API?
