Is Color Always Better? Maybe Not (Kelso)

Friday, January 23rd, 2009

[Editor's note: This beautiful example of strong graphic story telling printed grayscale in The Washington Post on January 12, 2009. The strong contrasts in tones of black ink were very successful. Sometimes we rush to colorize graphics unnecessarily. Just because we can, doesn't mean we must. This is a follow-up to my earlier post last year. I quote from there:

"Color graphics can fall into the trap of treating every category as equal. Doing so can create graphics without any focus or visual contrast. Often one category is more important than the other. Or colors used to symbolize nominal or ratio choropleth categories are so close together they are indistinguishable and create little or no visual appeal. There are also legibility problems associated with impaired color vision."

In the color version (below) that was converted for the web, color-blind compatible blue, orange, and red hues, but I think this and many other grayscale graphics that already exhibit strong figure-ground contrast could stay grayscale when posted on the web.]

Bush Econ: A Legacy of Little Growth (view original).

Economy Made Few Gains in Bush Years, Eight-Year Period Is Weakest in Decades

President Bush has presided over the weakest eight-year span for the U.S. economy in decades, according to an analysis of key data, and economists across the ideological spectrum increasingly view his two terms as a time of little progress on the nation’s thorniest fiscal challenges.

The number of jobs in the nation increased by about 2 percent during Bush’s tenure, the most tepid growth over any eight-year span since data collection began seven decades ago. Gross domestic product, a broad measure of economic output, grew at the slowest pace for a period of that length since the Truman administration. And Americans’ incomes grew more slowly than in any presidency since the 1960s, other than that of Bush’s father.

Bush and his aides are quick to point out that they oversaw 52 straight months of job growth in the middle of this decade, and that the economy expanded at a steady clip from 2003 to 2007. But economists, including some former advisers to Bush, say it increasingly looks as if the nation’s economic expansion was driven to a large degree by the interrelated booms in the housing market, consumer spending and financial markets. Those booms, which the Bush administration encouraged with the idea of an “ownership society,” have proved unsustainable.

“The expansion was a continuation of the way the U.S. has grown for too long, which was a consumer-led expansion that was heavily concentrated in housing,” said Douglas Holtz-Eakin, a onetime Bush White House staffer and one of Sen. John McCain‘s top economic advisers for his presidential campaign. “There was very little of the kind of saving and export-led growth that would be more sustainable.”

“For a group that claims it wants to be judged by history, there is no evidence on the economic policy front that that was the view,” Holtz-Eakin said. “It was all Band-Aids.”

Comic: Converting to Metric (XKCD)

Tuesday, January 6th, 2009

[Editor's note: Helpful hints on how to go metric if you never had a science class in the US since the 1970s. I don't yet dream in metric but I ain't afraid of it ;) Thanks Jo!] 

Republished from XKCD: A webcomic of romance, sarcasm, math, and language.

The key to converting to metric is establishing new reference points. When you hear “26° C,” instead of thinking “that’s 79° F” you should think, “That’s warmer than a house but cool for swimming.” Here are some helpful tables of reference points:

KML to Shapefile File Conversion (Zonum)

Friday, December 12th, 2008

[Editor's note: Useful free tool for converting KML files to Shapefile for use in the GIS. Thanks Mary Kate!]

Republished from Zonum Solutions. Kml2shp file conversion

Need of transferring Google Earth Data to a GIS? Kml2shp transforms KML files into ESRI Shapefiles.

Download. Windows program. No Mac version.

The KML file could contain Points, Paths and Polygons. When creating SHP files the information is separated into thematic layers.

For each shapefile (shp), an attributes table (dbf) and index file (shx) are created.

The kml to shp conversion consists of three steps:

1) Open KML file
2) Choose Shape Type
3) Select output Shapefile name

Optionally, you can change from WGS84 to a local datum and from Lat/Lon to UTM.

Also, Kml2shp can export to AutoCAD (DXF) and GPS (GPX)

kml2Shp is a beta freeware tool. This program doesn’t need to be
installed, just unzip it and run it.

kml2shp.zip contains the executable file (kml2shp.exe) and some bpl files. If you receive a message error about missing bpl files, come back here and get them.
