Define Search Criteria and Filtering
There are many ways to search for the stations using the Advanced Search feature in Report Generator. In the top left quadrant of the Advanced Search page is a Station Selection Criteria section. Each of the text fields accepts a comma-separated list of wildcard patterns (only the asterisk '*' and '?' wildcard characters are understood).
The following table describes the different search criteria fields:
|
Search Field
|
Description
|
|
Station ID
|
The station id of the stations. This can include wildcards and can be a comma separated list of station ids. If wildcards are used, the '*' can be used to match any number of characters and the '?' can be used to match a single character.
|
|
Station Name
|
The name of the station. This can include wildcards and can be a comma separated list of station names or station names with wildcards.
|
|
State
|
The two-character state FIPS alphabetic code (such as 'OR' for Oregon or 'WA' for Washington). This can be a single state code or a comma separated list of state codes.
There is also an undocumented feature that allows you to search for stations under the jurisdiction of a particular Data Collection Office (DCO) by entering the 2-character state code of the DCO followed by the letters 'DCO'. For example, if you want to search for stations in the Oregon DCO, type 'ORDCO' in the 'State' search field. You can enter more than more DCO in the same way that you enter more than one state. You can also enter a state and a DCO, but what results is the intersection of the DCO and the states entered (if you enter ORDCO and OR, you'll get only the stations that are in OR and in ORDCO)
|
|
Network
|
The network code of the station(s). Zero, one, or more networks can be selected. To select a single network, just click on the item. To deselect a network or to add another network to the selection hold down the CTRL key and click on the network to select or deselect.
|
|
HUC
|
The hydrologic unit code. You can enter one or more 2, 4, 6, or 8 digit HUCs separated by commas.
|
|
Min/Max Elev
|
The minimum and maximum elevation of the stations. None, one, or both of these filter fields can be specified.
|
|
Active Sites Only
|
If this box is checked, only stations that are still active will be returned. If this is unchecked, any station that matches the search criteria will be returned, even if the station is no longer in service.
|
|
Elements
|
Used to select the elements that a station should have data for. If multiple elements are selected, a station will be returned if it has at least one of the elements selected
|
When the filter is executed, there is an "OR" operator placed between the comma separated items in a given field and an "AND" operator placed between the various filter fields.
Following are some examples which illustrate how to use the filtering capabilities:
Example 1 - Find station 10360900
Station : 103060900
State :
Network :
HUC :
Min/Max Elev :
Example 2 - Find all stations in California or Nevada
Station :
State : CA, NV
Network :
HUC :
Min/Max Elev :
Example 3 - Find all streamflow or reservoir stations in California or Nevada where the station name begins with "LAKE"
Station : LAKE*
State : CA, NV
Network : USGS (STREAM), BOR (RESV)
HUC :
Min/Max Elev :
Example 4 - Find all SNOTEL stations whose elevation is between 1000 and 7000 feet and are in HUC 18
Station :
State :
Network : SNOTEL/SCAN
HUC : 18
Min/Max Elev : 1000 to 7000
Example 5 - Find all stations in Oregon that have incremental precipitation
