Custom Observation Query


iMapInvasives allows any user with Level 1 or higher access to query the database and view a subset of observation records. As user level increases, additional query and view options are available. Users can choose between different query types (Full Data Query, Common Invasive Species, Early Detection, or Approaching Region), with the default query type set as Full Data Query.


Users can select the query criteria, and can choose how to view the results.


Query Fields by User Level


The fields displayed on the Full Data Query tab will change depending on your user level. Most of these fields are represented by drop-down menus or pick lists on the query form, allowing the user to build the query from predetermined values. A few fields allow you to pick multiple values (e.g., you can select more than one species from the drop down list).


By choosing different values from the drop-downs, you can craft very specific queries to view or display a subset of the iMap observation dataset. Some examples of queries that can be performed are listed below:


Example 1: all plant, animal, and insect observations in a certain county for a certain year

Example 2: all observations made by your organization

Example 3: all Garlic Mustard records that have been confirmed by an iMap administrator, within a specific watershed


The following chart summarizes what fields can be queried at which user level.


Types of Results


After setting your query parameters using the drop-downs and pick lists in the Criteria section, click one of the Results buttons.


  • View Table will produce a table of the observations that match your search; you can then click on a record in the table to view the full observation record.

  • View Report will produce a summary report of the matching observations (the report lists observations per species and the organizations reporting these observations).

  • View on Map will take you to the map screen and show the matching observations on the map. You can then click on the clusters or points on the map to pull up the observation ID and species name for those observations, which will then link to the full observation record.

Common Invasive Species Query


The Common Invasive Species query is a simple form with only one criteria: Geography. Choose a geography type from the drop-down (e.g., Waterbody, County) then the geography value (e.g., waterbody name, county name). You can then click the View Report button to generate a report for all the common invasive species reported in that geography. Common species are designated by your iMap Data Administrator and generally include commonly encountered or easily identified invasive species. These species often make good targets for citizen science, volunteer, or student groups for surveying and reporting invasive species in their area.

Here is a section of a Common Invasive Species query report:

By clicking on the View Species List link from the Common Invasive Species report, you will generate a quick list of common invasive species reported in that geography, or you can scroll down to the Species Found section of the report:

Early Detection Query


Early Detection queries will only show species that have one to three observation records in your chosen geography. The intent is to provide a list of species that are present in your area of interest but have not yet become widely established. Once you choose your geography of interest (e.g. county, conservation area, waterbody) you can also give a buffer distance. For example, if you give a buffer distance of 2000 feet, your results will show species that have three or fewer reports intersecting or within 2000 feet of your area of interest.

Here is an example of the resulting Early Detection report:

You can open a list of the observation records with links to the detailed records, or click on View Species List to open a list of the species reported from the Approaching Region query, or scroll down for the species list:

It’s likely you’ll get some reports for species that simply haven’t been reported much but that are not Early Detection/Rapid Response (EDRR) species. This could encourage you to enter a couple quick observations to put these species over the EDRR threshold. Or you can simply ignore those species in the report and focus on the ones you know are priorities. While the Early Detection query does not display results on a map, once you have noteworthy species in mind from the report you can use the Map Query to locate the precise locations of those observations.

Approaching Region Query


The Approaching Region Query can also be used as an early detection tool. This type of query shows what species have been reported in your surrounding geographies but have not yet been reported in your geography. For example, if you choose your home county as your geography in an Approaching Region query, the results will show the species that have been reported in adjacent counties but that have NOT been reported in your county. Here too you can provide a buffer distance, which in this case will search that area inside your chosen geography (i.e., a buffer of 50m for Crook County will report from surrounding counties and 50 meters inside of Crook County’s border).
