This field allows a polygon to be provided in order to constrain results geographically. The polygon must be provided in a closed format of comma-delimited coordinate pairs.
Example:
-109.35 36.7875,-105.525 40.725,-104.5125 37.0125,-107.1 35.4375,-109.35 36.7875

Northern bound of a geographic envelope used to constrain results geographically.
If a northern bound is provided, an east, south, and west value must also be provided.

Eastern bound of a geographic envelope used to constrain results geographically.
If an eastern bound is provided, a south, west, and north value must also be provided.

Southern bound of a geographic envelope used to constrain results geographically.
If a southern bound is provided, a west, north, and east value must also be provided.

Western bound of a geographic envelope used to constrain results geographically.
If a western bound is provided, a north, east, and south value must also be provided.

Desired type of search query. Possible values are "count", "rowdata", and "distinctitems"

count: returns count of results from query.
rowdata: returns table of results from query in the format of "outputtype" below.

Desired output type from query. Possible values are "html", "csv", "xml", "json", "jsonp" and "staticmap".

html: returns HTML table of results from query.
csv: returns CSV table of results from query.
xml: returns XML document of results from query.
json: returns JSON document of results from query.
jsonp: returns JSON string wrapped in a Javascript function call defined by "jsonpfunction" below:
staticmap: returns map image of results from query.

Please note: When a searchtype of "count" is set, "html", "csv", and "staticmap" will return a plaintext integer count of samples from the query.

Desired Javascript function to be wrapped around JSON in the event that "outputtype" is set to "jsonp"

These values determine which rows of query will be displayed. The first row is always 0 and the last row is always the count value minus 1 (n-1).

Important: A maximum of 50 rows are allowed to be displayed at a time. Any start/end values that exceed a difference of 50 will result in the start value and start value + 50 values being displayed. If start/end values are not provided, rows 0-49 will be displayed.

Control display of column names in CSV and HTML output modes. Possible values are yes and no. Default value is no.
