How can I download 3D Elevation Program (3DEP) standard DEM data in bulk?

1. To request bulk elevation data, please email and provide the following:

  • Your contact information (address, phone number, and email address).

  • Product(s) you are requesting.

  • Requested data format(s).

2. An email will be sent to you containing the following information:

  • Job ID Number.

  • Size estimates for requested data.

  • External drive minimum specifications.

  • Shipping address.

3. Once you receive the email, you will then ship the following to USGS:

  • Correct number of external hard drives based on the estimated size of the data requested (specifications for hard drives are listed below).

  • A copy of all correspondence emails – please highlight the Job ID Number.

  • Return shipping address and phone number.

  • Return shipping account number (FedEx only) or pre-paid return shipping labels (UPS or FedEx only). Sorry, we cannot ship via USPS.

Specifications for external hard drives:

  • USB 2.0 compatible and higher.

  • PC compatible.

  • Capacity – large enough for estimated data, usually 30 to 40 gigabytes (GB) for system use. For example, a 300 GB external hard drive holds 277 GB of actual data; 500 GB hard drives hold 460 GB; 1 Terabyte (TB) hard drives hold 930 GB; 1.5 TB hard drives hold 1386 GB; 2 TB hard drives hold 1860 GB; 3 TB hard drives hold 2790 GB; and 4 TB hard drives hold 3725 GB.

  • Accepted capacity range of 8 GB to 8 Terabytes.

  • Cache Buffer – 8 megabytes or higher.

  • Spin Rate – 7200 RPM (can be less but this is preferred).

  • Drives are reformatted to NTFS; any existing data already on the external hard drive will be lost.

Please note:

  • We cannot process your request unless we have the correct number of drive(s); a listed Job ID Number; and return shipping account or pre-paid shipping labels.

  • Data will be written to hard drives in a compressed (.zip) format.

  • Turn-around time will depend on our current workload when an order is placed, but in most cases you will receive the data in 1 – 2 weeks.
