Yes and no. Drawing a large amount of data on a screen at one time is a drain on computing resources and drastically slows down viewing and querying data on the iMapInvasives map. For this reason, when you are zoomed out to a large area on the map, the exact point and polygon records stored in iMapInvasives are summarized to a hexagon layer. A hexagon with a larger circle represents an area with more records, while smaller circles represents fewer records.

​

iMapInvasives also provides Web Map Services which can be used with your own GIS programs such as ArcMap and Google Earth. This may be a better method for viewing large numbers of records at large scales.

​

As far as downloading records, users can download up to 10,000 records at a time. This number is set to limit the drain on resources to other users and prevent the site from being bogged down by large requests. If you need a large amount of data you can download smaller amounts at a time, or you can contact your iMapInvasives Administrator for a custom export.
