Syntax

lon=number

the longitude, in decimal degrees, of the center of the map. Remember that longitudes for the Western Hemisphere are negative numbers. Longitudes for the contiguous U.S. range between about -67 and -125 degrees.

lat=number

the latitude, in decimal degrees, of the center of the map. Latitudes for the contiguous U.S. range between about 24 and 49 degrees.

wid=number

the desired width, in decimal degrees of longitude, of the coverage of the map. The actual coverage of the map may vary slightly from this number, due to fitting the requested coverage to the shape of the image.

ht=number

the desired height, in decimal degrees of latitude, of the coverage of the map. May turn out slightly different, for the reason above.

iwd=number

the image width, in pixels. If none is specified, the default is 512.

iht=number

the image height, in pixels. If none is specified, the default is 256.

legend=on

if included, the legend graphic is returned rather than the map.

mark=lon,lat,symbol,label;...

if included, places one or more markers on the map at the longitude and latitude given. The label, if included, is the text to be displayed adjacent to the marker (the label must by URL-encoded, i.e., replacing spaces with +). The symbol is the graphic symbol used to mark the location. Currently, the following symbols are supported:

smalldot (default if none specified), bigdot, home

redstar, bluestar, cross

interstate-1, ushwy-1, statehwy-1

interstate-3, ushwy-3, statehwy-3

redpin grnpin blupin, orgpin, purpin, magpin, brnpin lgrpin, cynpin, grypin, whtpin,

redball grnball, blueball,

red5 green5, blue5, purple5, brown5, black5

red4 green4, blue4, purple4, brown4, black4

red3 green3, blue3, purple3, brown3, black3

More than one marker can be placed, by separating the marker parameters with a semicolon (;). However, the allowable number is limited by the 256-character URL limit (which amounts to about 6-8 points).

murl=URL

this gets over the above marker limit by allowing the requestor to submit an entire list of points. This list is placed in a separate file, which must be in a place visible to the world via HTTP (i.e., on your own web server). The URL given is the address used to retrieve this file. The format of the file is as follows:

#tms-marker        (a flag on the first line to identify the file type)
lon,lat:symbol:label  #optional comments after a pound sign
lon,lat:symbol:label  #labels are optional, but you still need the colon
lon,lat:symbol:label  #  after the symbol.
lon,lat:symbol:label

where lon, lat, symbol, and label are defined as above (except that the label is not URL-encoded). An example marker file might be useful.

on=layer,layer,layer

off=layer,layer,layer

forces individual feature layers to be displayed, or not displayed, respectively. These fields override, but don't replace, the natural layer selection (i.e. layers not mentioned may still be displayed or not, depending on the default scheme). The following layer names are valid:

• GRID (graticule, along with margin labelling)
• BACK (blue background)
• CITIES (labels on places)
• states (state boundaries, which also form white land fill over BACK)
• counties (county boundaries)
• places (cities and towns)
• majroads (expressways and other highways)
• streets (normal streets-don't turn this on when zoomed way out)
• railroad (railroads)
• water (water bodies, including linear streams and areal features)
• shorelin (lines bordering areal water bodies)
• miscell (miscellaneous features, including parks and schools)

tlevel=level

selects a geography level for drawing thematic statistical maps (must be used with tmeth and tvar). The available level codes are:

• states
• counties
• msa (1991 Metropolitan Statistical Areas)
• con_dist (1992 House Congressional Districts)
• places (cities, towns, and CDP's)
• mcd (Minor Civil Divisions-New England only)
• tracts (Census Tracts: 15-20 city blocks)
• censusb (Census Block Groups: 4-5 city blocks)

tvar=variable

selects a statistical variable to use in thematic maps (must be used with tlevel and tmeth). So far, not all the 1990 census variables are in the database, but the following can be used:

• famsize (Family Size: persons per family)
• hhsize (Household Size: persons per household)
• density (Population Density: persons per sq mi)
• income (Median Family Income)
• p0-4 (% of Population Age 0-4)
• p5-9 (% of Population Age 5-9)
• p10-19 (% of Population Age 10-19)
• p20-49 (% of Population Age 20-49)
• p50-64 (% of Population Age 50-64)
• p65- (% of Population Age 65 and over)
• white (% of Population White)
• black (% of Population African-American)
• indian (% of Population American Indian)
• asian (% of Population Asian)
• hispanic (% of Population Hispanic)
• other (% of Population from other ethnic groups)
• owners (% of Households Owner-Occupied)
• renters (% of Households Renter-Occupied)

tmeth=q or i

selects the classification method to use in thematic maps (must be used with tlevel and tvar). Can either be "q" for Quintiles (5 classes of equal size) or "i" for Equal Interval (5 classes with an even range of values). These classes are calculated over the entire country, not just the map area. Quintiles tend to provide better contrast between values around the average, while Equal Interval tends to emphasize the extremes (but this is not a hard and fast rule).
