JAN 3 1 1978

Mr. Olin E. Teague, Chairman
Committee on Science and Technology
House of Representatives
Washington, D.C. 20515

Dear Mr. Teague:

This is in further response to your December 19, 1977, letter in
which you asked for our views on future-space programs.
The enclosed statement, is submitted for the consideration of
you and your Committee.

We appreciate the opportunity to present our thoughts on future space programs as they relate to the Foreign Agricultural Service. Mr. Howard W. Hjort, Director of Economics, policy Analysis and Budget, has overall responsibility for Remote Sensing Policy coordination for the Department of Agriculture. If the Committee wishes additional information concerning the total Department of Agriculture remote sensing activities, plans or policy, Mr. Hjort should be contacted in the future.

FAS Programs and Information Requirements

As the primary program and policy support arm of the U.S. Department of

Agriculture in international affairs, the Foreign Agricultural Service (FAS)

has a special interest in utilizing space-acquired data. FAS's mission is

to help develop and expand foreign markets for U.S. agricultural products;

to provide representation for the Secretary of Agriculture and the U.S. farm community in foreign countries and international forums; and to assist in

formulation and execution of u.s. agricultural and foreign policies.

To accomplish this mission, accurate and timely information regarding world agricultural production and trade conditions is needed. FAS employs

analysts both here and abroad to gather this information and to provide the

analysis needed to carry out the agency's responsibilities.

Utilization of space-acquired data would amplify the ability of FAS to

assess world crop conditions.

For example, world agricultural production

could be monitored more accurately in-season, and changes due to drought or

crop diseases could be detected more quickly. Used in conjunction with weather and climate data and traditional agricultural information resources,

space-acquired data could provide a better basis for FAS policy and program


USDA's Interest in Remote Sensing

The Department of Agriculture is a long-time user of remote sensing, beginning with the use of aerial photography more than 40 years ago. It

uses remote sensing in a wide var iety of ways, including land measurements;

- 2

crop, forest and soil inventories and condition assessments; mapmaking;

land surveying; and fire detection and monitoring. Since the early 1970's,

beginning with the launch of ERIS-1 (later renamed Landsat-1), we have been

interested in the potential of space technology as a new and valuable source

of data which could help this and other Executive Branch agencies to meet

their statutory responsibilities.

Two satellites, Landsats-1 and 2, have been providing multispectral

data over large areas since mid-1972. The Landsats cover the same areas

at frequent intervals and deliver data in computer processable form.

A third satellite, Landsat-C, to be launched this year and its new ground processing capability will make Landsat data available to users

in a matter of days instead of weeks.

Landsat-D, to be launched in 1981,

will provide substantially improved spacial and spectral resolution. We believe that these current and planned Landsats are providing us with an opportunity to develop, test, and evaluate ways to exploit space technology

as an additional source of data for the Department's information systems,

Consequently, FAS and other agencies are actively engaged in developing

and testing applications of Landsat data. Examples of these efforts

The Large Area Crop Inventory Experiment (LACIE) is a joint

effort of USDA, the National Aeronautics and Space Administration (NASA),

and the National Oceanic and Atmospheric Administration (NOAA). The LACIE

objective is to develop, test, and evaluate a system to forecast foreign

Because of its responsibilities in the collection, analysis, and dissemination of foreign commodity supply/demand information, FAS has USDA lead responsibility for LACIE. However, other Departmental agencies are also participating in the experiment, including the Agricultural Stabilization and Conservation Service (ASCS), Economics, Statistics and Cooperative Service (ESCS), Federal Crop Insurance Corporation (FCIC), Science and Education Administration (SEA), and the Soil Conservation Service (SCS). Phase I of LACIE, which began in November 1974, was devoted primarily to assembling and testing the various components of the experimental system. Phase II (1976 crop year) was a test of LACIE's ability to make in-season estimates of acreage, yield, and production for the wheat crop in the U.S. Great Plains, Canada, and two indicator regions in the Soviet Union. While spring wheat in the Northern Great Plains and Canada was significantly underestimated, LACIE at-harvest production estimates in Phase II were very close to final official estimates. Phase II LACIE research was directed toward development of techniques and procedures to overcome problems discovered in Phase I. During Phase III (1977 crop year), LACIE produced in-season wheat estimates for the U.S. Great Plains and the Soviet Union; directed research and testing efforts toward problem solving; and procured the first components of a USDA system which will test and evaluate technology developed through the joint USDA/NASA/NOAA program. Final Phase III evaluations are not yet complete, but we have determined that the LACIE estimates for the U.S. Great Plains were within 9 percent of the official SRS estimates. Comparisons of LACIE estimates for USSR with official estimates are not possible at this time since official estimates available so far for 1977 are for total grain, whereas LACIE estimates are for wheat. However,



is significant that the LACIE successfully picked up indications of the

statistics are made available later this spring. The current LACIE pro

ject will end with the completion of the final evaluations in mid-1978.

USDA, NASA, and NDAA are currently planning a follow-up to LACIE, which

will begin 1979.

This new program will build on LACIE experience and will

expand research, development, and testing to additional crops, regions, and
