Previously I have shown how to use colored pushpins to make your Map-O-Matic maps more visually appealing. In this tutorial, I will demonstrate a couple of scenarios where you can use color to not just “prettify” a map, but also to convey information.
Specifically, in the first instance, I will show the capitals and most populous cities of selected western States. In some cases, the two are the same, so there is only one pushpin for those States. The capitals are red, the most populous cities are blue, and when both are the same city, the single pushpin for that State is purple.
The list is:
Red~California Capital: Sacramento;38.534495;-121.481287
Blue~California Most Populous: Los Angeles;34.086480;-118.393615
Red~Oregon Capital: Salem;44.928005;-123.047920
Blue~Oregon Most Populous: Portland;45.511790;-122.675600
Red~Washington Capital: Olympia;47.043090;-122.891057
Blue~Washington Most Populous: Seattle;47.599403;-122.314394
Purple~Utah Capital and Most Populous: Salt Lake City;40.774091;-111.936952
Purple~Arizona Capital and Most Populous: Phoenix;33.535540;-112.072800
Purple~Colorado Capital and Most Populous: Denver;39.668473;-104.912296
Red~New Mexico Capital: Santa Fe;35.674948;-105.946240
Blue~New Mexico Most Populous: Albuquerque;35.111758;-106.638014
Red~Montana Capital: Helena;46.597192;-112.020513
Blue~Montana Most Populous: Billings;45.786751;-108.551273
Purple~Idaho Capital and Most Populous: Boise;43.596422;-116.225672
Purple~Wyoming Capital and Most Populous: Cheyenne;41.144247;-104.799184
Red~Nevada Capital: Carson City;39.157693;-119.766313
Blue~Nevada Most Populous: Las Vegas;36.219565;-115.285569
And here is the map that is created from that list, along with a caption segment I added:
The second, similar, example, is of county seats and most populous cities (or towns) in selected California counties. Here is the list for that:
Red~Calaveras County Seat: San Andreas;38.194456;-120.684333
Blue~Calaveras Most Populous City: Rancho Calaveras;38.127613;-120.857564
Purple~Tuolumne County Seat and Most Populous City: Sonora;37.982940;-120.382100
Purple~Mariposa County Seat and Most Populous City: Mariposa;37.509667;-119.968671
Purple~Madera County Seat and Most Populous City: Madera;36.981002;-120.088219
Purple~Fresno County Seat and Most Populous City: Fresno;36.725396;-119.809702
Purple~Monterey County Seat and Most Populous City: Salinas;36.684398;-121.636134
Purple~San Benito County Seat and Most Populous City: Hollister;36.852510;-121.402100
Purple~Merced County Seat and Most Populous City: Merced;37.325343;-120.542425
Purple~Stanislaus County Seat and Most Populous City: Modesto;37.654714;-121.004200
Purple~Santa Clara County Seat and Most Populous City: San Jose;37.314219;-121.910986
Purple~Santa Cruz County Seat and Most Populous City: Santa Cruz;36.969127;-122.040009
Red~San Mateo County Seat: Redwood City;37.486460;-122.225700
Blue~San Mateo Most Populous City: Daly City;37.688614;-122.472697
Purple~Alameda County Seat and Most Populous City: Oakland;37.808899;-122.282800
Purple~San Joaquin County Seat and Most Populous City: Stockton;37.957540;-121.292400
Red~Contra Costa County Seat: Martinez;38.016890;-122.135200
Blue~Contra Costa Most Populous City: Concord;37.979100;-122.031300
Purple~San Francisco County Seat and Most Populous (and only) City: San Francisco;37.781488;-122.461959
Purple~Marin County Seat and Most Populous City: San Rafael;37.974580;-122.531900
Red~Mono County Seat: Bridgeport;38.255790;-119.228900
Blue~Mono Most Populous City: Mammoth Lakes;37.647190;-118.967400
Purple~Kings County Seat and Most Populous City: Hanford;36.330040;-119.640000
Purple~Tulare County Seat and Most Populous City: Visalia;36.332609;-119.324306
As you can see, most of the county seats are the county’s most populous city or town, in which case the county has a solitary purple pushpin. Where the most populous city or town is not the county seat, the county seat is red and the most populous city or town is blue.
Here is that map:
Next week I will show another example of using color to convey information on maps.
