Interactive Google Maps Shows Locations of all the US Shale Oil and Gas Wells

Rating:

Post Carbon Institute has created an interactive Google Maps that shows over 63,000 locations of the U.S. shale gas and shale oil (tight oil) wells, using data from Drilling Info.

Regions for different plays (i.e. shale oil plays, shale gas plays, oil and gas plays) are highlighted in various colors on the map, however, there in no mouseover infobox for these regions. Details for individual plays (e.g. production date, well ID, gas production status) can be seen by mouse hovering the red points.

Presenting detailed information is always the main purpose of informative map, however, this Google Maps got a mistake in infobox design causes the low rating in our map reviews. The size and the position of infobox are fixed that there will be a scroll bar when the text content a bit longer for several points. However, the infobox is a mouseover event that the popup box would disappear once the mouse hovering off the point. So, how can the map users see the full infobox content by scrolling the scroll bar? The issue can be easily tackled by changing the event to mouse click box or re-size the infobox.

Interesting Heat Map Shows How Popular Your Name Is Across the United States Over the Past Century

We just found an interesting heat map that you could check the popularity of your (or your family and friend’s) name(s) across the U.S. in the past 100 years. Simply enter your name in the search box, select the gender, and then wait for the GIF heat map tells you the answer. interactive us heat map popular baby names

You could see the heat map about popularity of your name from 1910 to 2012, and detailed statistics can be found in mouseover box of each state.

Map Reviews: 3.5/5 Stars
This map is interesting for us to search how popular our names are in the past century. However, a timeline is omitted that we would not select specific period as the heat map is some kind of a GIF image. As there are so many regions in the heat map, it is impossible for me to mouseover all the boxes within one second for detailed information, therefore, I have to refresh the map and wait for the specific year again. It sounds a bit silly.
This heat map will be better if a timeline or a pause button is enabled.

Map Reviews: 3.5/5 Stars
We like this map, includes the map theme, the usages, the map color settings, and present of the marker list. However, it would be better if there is clustering feature, and improved performance for the filtering function.

Since there are over 600 points on the map, it would be better present those points with clustering, which is a way to group markers on the map based on factors, such as proximity or map data that makes the map leaner and cleaner without flooding with overlapping markers. You can get more idea about clustering in the following video:

Map: US Gender Pay Gap

We all know that there is gender pay gap that women get less salary than men on average, and we have shared an interactive Google Maps about this phenomenon in New Jersey before. Here we have found another U.S. for showing a wider picture of this issue.

heat map us gender pay gap

According to the above chart and map, we can see that women make 77 cents for every $1 earned by men in average, and women in Washington, D.C., Marland, Nevada, and Vermont can even earn more than 84 cents for every $1 the men make. However, the gender pay gap still exists, that happens in every county, and even female employees working in the White House make less dollar than men.

So you think the gender pay gap is an issue that has to be solved? Share your views with us.

This heat map is not user friendly to read as the color setting is a bit complicated. We would suggest using continuous color rather than the current discrete range color since the former can better present the differences of data values in various counties.

Usable Restroom Along MTA NYC Subway

Few weeks ago, we have share an NYC Subway map about best coffee by stop, and today we would like to share another one about usable restroom along the subway.

nyc-subway-map-all-subway-bathrooms-youtube-affixion96-untapped-cities-02

This MTA New York City Subway map about usable restroom is created along with a YouTube video created by Eron Watt to show those 48 subway restrooms he visited from 2009-2014. Out of NYC’s 468 subway stations, only 129 of them claim to have restrooms, and many of them are locked, though MTA spokesman claimed that the only times restrooms are locked is from 1 a.m. to 6 a.m. for cleaning purposes and prevention of crime, except when they are under construction.

Here is the video produced by Eron Watt:

Interactive Heat Map: Global Slavery Index 2013

According to the Walk Free Foundation’s Global Dlacery Index 2013, there are nearly 30 million slaves in the world, and almost 60,000 of them are living in the U.S. Here is an interactive world map about the index.

According to the Walk Free, slavery defines as one of the following: human trafficking, forced labor, debt bondage, forced or servile marriage, and the sale or exploitation of children including in armed conflict.

The index ranks 162 countries based on a combined measure of three factors: estimated prevalence of modern slavery by population, a measure of child marriage, and a measure of human trafficking in and out of a country.

The index is mapped into two maps: an interactive heat map & an interactive bubble chart. In the heat map, country with higher slavery prevalence is highlighted with darker red while country with lower slavery prevalence is highlighted with yellow. Map users could see details of each country by mouse clicking the region, or select specific category in the category legends.

In the bubble chart, countries are being plotted on the chart according to their prevalence rank vs human development index/financial service index/corruption index. However, there is no popup box of each bubble for detailed information, and no map legend to indicate various bubble sizes that a bit confuse the map users.

interactive heat map the global slavery index 2013

According to the index, 10 countries with the highest prevalence of slavery are Mauritania, Haiti, Pakistan, India, Nepal, Moldova, Benin, Cote d’Ivoire, Gambia, Gabon. Among all the above mentioned countries, India has the most slaves in the world, with an approximated 14 million. 

However, even countries like Iceland, Ireland, and the United Kingdom rank 160 in the index, it does not mean these countries are slavery free, for example, it is estimated there are between 4200 to 4600 “slaves” in the UK.

Map Review: 4.5/5 Stars
We love this map as the map design is simple but informative with clear instruction and indications for users to filter related information in seconds.
There are just minor suggestions to the bubble chart:

  • add a map legend to indicate the bubble sizes
  • insert infobox for each bubble for detailed information

Alternatively, showing data of each country with bubble can be presented on the world map rather than on the chart. Bubble chart map can be easily created in mapping software that you may take following video for reference:

Interactive World Map About Deforestation

According to the World Resources Institute (WRI), it’s estimated 500 soccer fields of forests are lost every minute. WRI cooperated with about 40 organizations, and has created the following Global Forest Watch (GFW), an online forest monitoring system, to see where are we losing the forests in real-time.

You can see related data by selecting specific items in the category legends, for example see the forest changes, forest cover (heat maps), forest use (e.g. logging/mining/oil palm). Using this map, we could track the effects of using forest illegally, for example the illegal gold mining in Peru’s Amazon.

We understand it is a sensitive issue to mention about the fate of France’s Jews in World War II, this map is an important tool for better understand the history, which we have to face.

Map Reviews: 3/5 Stars
You cannot see how “interactive” this map is until you zoom in to each point and mouse click for the details. In the popup box, you have to mouse click the inserted URL in order to read detailed information in the information column that on the right side of the map. This process is a bit unnecessary as popup infobox with detailed information can be directly shown once the map users mouse click the bubble. Here is a video for reference:

Please note the map supports French currently, and let see if versions in other languages would be released in the future as this map is an informative tool for related research and educational use.
