Select Region

To confine your GeoPackage to a specific bounding box, you can either draw a region on the map, or enter the region's boundaries in the Longitude Min, Longitude Max, Latitude Min, and Latitude Max fields. 

  • Coordinates should be entered in degrees.

Drawing a region:

To draw a region on the map, position your mouse at the top-left corner of your desired region, single-click, drag to the bottom-right corner, and single click again. This will automatically populate the Longitude Min, Longitude Max, Latitude Min, and Latitude Max fields.

Select Scale

You may set a minimum and maximum Scale value for the GeoPackage. Scales from 1:74,000,000 (least detail, smallest file size) to 1:2,222 (most detail, largest file size) are supported.

By default, the Min and Max Scale is based on the map's current magnification. You can adjust the map's magnification by using the + and - buttons to zoom in and out.

Setting Min and Max Scale:

To set the min/max scale fields:

  1. Zoom the map out the desired Minimum Scale using the - button

  2. Click the SET button for the Min Scale field

  3. Repeat the process by zooming to the desired Maximum Scale using the + button.

  4. Click the SET button for the Max Scale Field

Notification Email

Profiles

The Profile dropdown menu allows you to use a profile other than the default NSG GeoPackage (EPSG:4326).

If there's more than 1 GeoPackage server required for your selection, then a profile dropdown will be displayed for each server.

Size Limit

This optional field allows you to set a maximum limit on total estimated size of your GeoPackage. GeoPackage generation is disabled if the current configuration exceeds that limit.
