Description:
Trophic Status Index (TSI) for a water unit.
Search parameters:
One or more of the following search parameters need to be specified in order to retrieve data:
| wid |
Yes |
The ID for the water unit.
|
Additional parameters:
The following, optional, parameters may be specified:
| format |
The desired return format. Valid formats are: {json, jsonp, text, csv, xls, ods, and tab}. The default is json. |
| callback |
The JSONP callback function name (Note that format needs to be "jsonp"). |
| fields |
The comma-separated-list of the field names to return from the query. The default is to return all available fields. |
| nullValue |
Value to substitute in place of null values. The default is to return null values as "null" (per JSON.org). |
| limit |
The number of records to limit the result set to. Behaves like the SQL standard LIMIT clause. |
| offset |
Used with Limit-- the record number to start retrieving from. Behaves like the SQL standard OFFSET clause. |
