Troubleshooting Tips


Map View

  • If something is not showing up on the map, move the page slightly or zoom in and out. Be patient, data can sometimes take a while to appear.

  • If the points or polygons are taking a while to load on the map, try turning off all layers, zooming in to the location you are interested in, and then turn on your point or polygon layers.



Data Entry

  • If you are unable to enter or edit data in iMapInvasives, one of the reasons may be due to your user level. Check out the User Level section to learn about the user level system and the data types you can enter with each level.

  • Once an observation is confirmed by either the state administrator or a project leader, that record is now locked and uneditable. In order to edit your confirmed observation record, contact your state administrator and request that the record be unconfirmed so that you can make any necessary edits.

  • When entering an observation, at Step 5, the calendar defaults to the date of data entry. If you need a different month or year click the month or year at the top of the calendar box to scroll more quickly back in time. You can also use the arrows to scroll to your date











  • Having trouble saving your record or drawing polygons? Perhaps it's due to the browser you’re using. FireFox, Chrome, and Safari are preferred web browsers. Older versions of Internet Explorer (older than IE 10) are not compatible with iMapInvasives.


User Login

  • If you’ve forgotten your username, contact your state administrator and he or she will provide you this information. In many instances your username will be the first three letters of your first name and all of your last name with no spaces in between (Example: Leroy Brown = lerbrown).

  • If you’ve forgotten your password, go to the login page for your state or province and click on “Forgot Password.” From there, type in the email address or the username tied to your account. An email will be sent to you with a link to reset your password.

  • Sometimes the email address linked to your user account is out-of-date (e.g., the email address on file is from a previous job and is no longer active). In this case, you will need to contact your state administrator directly so he or she can change the email associated with your account.


General Inquiries

  • After a version update, you must clear your browser’s cache before logging on to iMap. An easy keyboard shortcut is ctrl + shift + delete and select clear your cache and then hit the F5 key to refresh the page.

  • Look at the documents under the “Resources” tab to see if your question can be answered.

  • When reporting any issues to your Data Administrator, be as detailed as possible when describing what you were doing. Screenshots and URLs are very helpful, as are step-by-step descriptions of what you were doing before the issue occurred.
