During 2021 existing AISAP data and personal projects will be migrating to the AISAP-Cloud site, https://aisap.usacegis.us/aisap_portal. All users are encouraged to create AISAP-Cloud accounts and start new projects on that site.

This version of AISAP (http://ais-portal.usace.army.mil) will be unavailable after January 1, 2022.
AIS Analysis Package (AISAP)
AISAP provides access to the USCG NAIS archive of AIS records. To search the AISAP library, go to Data Requests: Find Requests above. To request data from the USCG NAIS archive, use the Query Tool available under the Data Requests menu.
Once the data is available within the AISAP library, create a folder and project below. Select a data source for the project. Draw or import shapes for your areas of interest (AOIs) on the map.

Query Tool for NAIS Archive
Complete the form below to retrieve data from the USCG NAIS archive for use in AISAP. Each submission constitutes a request in AISAP. Please note that position reports more than three years old are not retrievable.
An email will be sent to the provided email address when the request is complete. The time from submission to completion varies from minutes to days depending on the amount of data requested.
Before submitting a new query, check to see if data is already available in the data library. Go to Data Requests: Find Requests above.
If a large time period of data at a high sampling rate is required, break the request into multiple, shorter time periods. Use the Reload Request Parameters button at the bottom of the page to quickly fill in the request fields, then change the date range and request description appropriately.

Download Files
After a submitted request is complete, the files listed below will be available. To verify that the request is complete, select the Request Status Lookup link under the Data Requests menu.
Enter the associated request number to download the desired files.
Find Requests in AISAP Library
Search for completed requests in the AISAP library that are available for use as project data sources in AISAP. If no requests are found based on the criteria you submit, broaden your search or select the Query Tool link from the Data Requests menu above to retrieve data from the USCG NAIS archive.
