logo Calflora Group Observations Help
The Group Observations application lets you search for plant observations associated with any group of which you are a member, and see them on a map.

This application is similar to Observation Hotline (see Observation Hotline Help for details), but has some additional features which are useful for managing the records of a single group. For instance, Group Observations will show unpublished records associated with a group, where Observation Hotline will only show published records.

If you have any questions about this application, please contact Calflora support.

Search Criteria

Start Date and End Date are inclusive. Dates are entered in the format YYYY-MM-DD so that February 20, 2017 is written as 2017-2-20. If you enter 2017-2-20 as the end date, the result will include records that were entered on or before 2017-2-20. If you put the same date in both Start Date and End Date, the results will only include records entered on that date.

Other search criteria in this application are largely similar to Observation Hotline. These additional criteria are available:

shape Return only those records that have a line or polygon.
point Return only those records that do not have a line or polygon.
no treatment records Return only those records that do not concern treatment of a patch.
only treatment records Return only those records that concern treatment of a patch.
only herbicide records Return only those records that concern herbicide treatment of a patch.
under management Return only those records marked as under management. By default, all records that concern treatment are marked as under management.
History Filter
0nly the most recent This option is relevant when there may be multiple records concerning the condition of a single patch over time. When this option has been chosen, a single record (the most recent) will be returned for each patch, even if there are many records describing that patch.

When this option has been chosen, two columns appear at the beginning of the result set: Root and Most Recent. When historical information is available about a patch, the Root record will be the oldest, and the Most Recent record will be the newest. Click on either one to view it in Plant Observation Entry.

When historical information is not available about a patch, the record ID appears in the Root column. (When there is only one record of a patch, that record is both the earliest and the most recent.) In this way, the record number in the Root column serves as a unique identifier of a patch.

0nly root records When there may be multiple records concerning the condition of a single patch over time, this option will return only the root, or oldest, record.
Project (Weed Manager organizations only.) Return only those records associated with certain projects.


The results appear simultaneously as points on the map and in a table below the map. This application will display both published and unpublished records.

If you click on a point on the map, an InfoWindow opens at the point, the table scrolls down to the corresponding record, and the record ID is highlighted. If you click on a record ID in the table, an InfoWindow opens at the corresponding map point, and a short menu opens up under the record ID.

Press DETAIL in this menu to see a page showing full details of this record (including any comments that Calflora contributors may have made about the record).

Press edit in this menu to edit the record with Plant Observation Entry.

The results can viewed through one of several column sets, such as Basic Data and Weed Data Export. You can also make up a custom column set: open customize, and choose the columns you want.

If you are part of a Weed Manager organization, additional column sets are available, one for each of the data collection forms that your organization uses.


To download the result data onto your local computer, open TOOLS / DOWNLOAD RESULTS, and choose a format. Supported formats include various kinds of flat files, and three kinds of shapefiles.

With respect to shapefiles, if you choose Shapefile: polygon, the shapefile will include only those records that have a polygon. If you choose Shapefile: point, the shapefile will include all records.

Shapefiles suffer from the limitation that an attribute name cannot be longer than ten characters. (The other available formats do not suffer from this limitation.) When you extract a shapefile with this application, attribute names are deliberately shortened, The meaning of the shortened names is explained in this Data Dictionary.


You can save a Group Observations search and run it again later. To save the current search, open TOOLS / SAVED SEARCHES. Choose a name for the search, and press .

To see all of your saved searches go to MyCalflora / Searches. For Weed Manager organizations, to see all searches associated with your organization, go to Organization Options / Searches.


Once you have used customize to choose exactly the right set of columns, you can save that set by name, and use it again later. Open TOOLS / SAVED COLUMN SETS, choose a name for the column set, and press . Any column set you save will be available to other members of your organization.

To bring back a previously saved column set, open TOOLS / SAVED COLUMN SETS, and choose a column set by name from the drop down.


The Multiple Record Editor is a feature of this application which can make changes to many of your group's records at the same time. It is a powerful and potentially dangerous tool.

Using the editor is a two step process. First, you use the criteria on the left hand side of the page to search for matching records. Then you open the editor, and specify a change to one or more fields.

To open the editor, enter some search criteria, press , and then open Tools and press .

In the editor panel, you can specify changes to the records that match your search. Once you have entered the changes you want to make, press . This action wil ask you to confirm, and then apply the changes to all of the records that match your search, even if you cannot see them in the result table.

For instance, to publish all matching records, set Access by other users to published. Press to make the changes happen.

Note that changes made by the Editor are not recoverable.
