Viewing the Map


The map is available for the public to view, it does not require an iMapInvasives account. Species reported in your state/province are chosen by your iMap program, so the public map may not include all the species tracked by your iMap program. In order to see additional information you must request a User login.


When viewing species distributions, please note that these represent data that have been submitted to iMapInvasives. Absence of data does not always indicate absence of the species.


To view the map go to the iMapInvasives login page and scroll to your state of interest.

Login:  Goes to the sign in page for iMapInvasives where existing users can login and new users can request a login. 


Find Record: Allows the public to look for a confirmed presence record by the record id.


Filter Records: Allows the public to search for confirmed presence by species.


Identify/Measure: This button allows you to draw an area (polygon) or distance (line) to identify the records in that location.  After an area is defined, you can "see what's here" and view the basic details of each record.  

Close Layers:  This button collapses the layers on the upper right corner of the map.

As a registered individual iMapInvasives user, you will have more tools available to you. Along the top of the map, six buttons will appear for your use.  As a registered iMapInvasives user, in addition to the tools mentioned above, you will be able to create a record and export data.

Create Record:  Allows the user to add Presence, Not Detected, and Search Areas records.  

Export Record:  Allows the user to export spatial data.  The available data types are geodatabase (gdb), shapefile (shp), or CSV.
