of tbl• pbotoaraphy. the Def aency (DMA) baa produced 

about 53.000 different maps and of a current requirement of 

10,000 levied by the Unified and Specified Commands. the Military Service■• 

and the lntelllaence Community. These maps and chart■ have been produced 

at variou■ cale■ for air, ground, sea. and space operations, intelligence. 

and military plannin1. The geocletlc c1=dbv the military mapping 

community have provided the many t ;lcc:ur·ate point locations 

needed for operation of strategic. and tactical missile and air strike tern■• 

At the pre ent time, 95 percent of all photography uaed in military mapping 

application■ is of satellite ori1in.

military mapping, charting, and geodetic production activitie■ have several 

different pecta. They include coveraae of various areas of the 'WOJ'ld by

(Circular Error -- 90\ probability) with reference kl the World Geodetic 

System la the drivin1 future requirement for the horizontal accuracy portion 

of the military MClG products. Thia technical objective. which would be 

hi. aupport of the Advanced ICBM (MX). would require repositioning all of 

the 2,400 Cateaory 1 targets in the National Strategic Target Data Base 

(NSTDB). The NSTDB currently conai1ta of approximately 24,000 targets, 

predominantly in Communist areas. At the present time, OMA has a major 

production effort under way to po•ition the Z,4.00 Category I targets, plus 

some Category II targets, to the current requirement of 205 feet horizontal 

accuracy by early 1975. The present KH-9 mapping camera •ubaystem is 

1enerally exceeding this accuracy requirement. Table 2 indicates that 

the maximum horizontal accuracy with reference to map grid or to local 

datum ■ 40 feet for U.S. 1:24,000 line map• -- however, this figure is 

not a clrivlna factor lor the NRP. The next most rigorous current accuracy 

requirement with referenee to map &rid or loc:al datwn is 66 feet for the 

Deployable Point Po&itionina Data Ba•e. which includes such specific 

application• as the Lance Missile and the calibration of Loran C and MSQ 

Radar, for the western border of the USSR, Central Europe, Korea. 

Sou.theaat Aaia, and Cuba. 

B. Drivinl Vertical Accuraciu 

5. Drivin1 vertical accuracies with reference to the World 

Geodetic Sy tem all relate to the National Strateaic Taraet Data Base and 

are concentrated in the built-up Communi•t areas. Pre•ent validated 

requJ.rementa call for 9S feet vertical accuracy in the poaitionina of the 

Cate1ory I tar1eta in the FY 76-79 period, and 9S-300 feet for the remaining 

Cate1ory II tar1eta after FY 75. The technical objective for the Advanced 

ICBM for FY 80-on is 75 feet for the Cates:ory I taraet1 <••• Tables 3 and · 4).

lar1e scale maps. However. these requirements are :not driving: factor■ 

for the application and deaia;n of NRP satellite syatems. and are mentioned 

for information only. The most stringent vertical technical objective 

applicable to NRP systems is 20 feet (Linear Error: -- 90\ probability) over 

ten n:>.utical mil•• with reference to map arid or local datum for TERCOM 

in the Communist areas. The most rigorous currently validated requirement is 33 feet over a distance of 20 nautical mile■ for the l: 2S. 000 and

China. the North African coast. and Southeast Asia. Other military MC.C

8. Stereo Coverase 

9. In areas where accurate ground aurvey data are not 

available, stereo tri-lap MCS photo coverage is required for pTeci e 

po•itloaiaa of points on the around. Areas where accurate ground survey 

data are available include portions of the US and most of Europe. Stereo 

ICH-4 or KH-9 panoramic coverage is al110 required to permit automated 

development of contour line• in areas where large scale topoaraphic maps 

are produced. Monoscopic KH-4 or KH-9 pan cov'!lraae is acceptable for 

revision of metrically accurate but culturally out-of-date mapa. However, 

stereo coverage from the KH-9 pan, tbe KH-8, or the KH-ll syatem is 

required for obtaining data on which to base radar reflectance patterns 

and .for performing radar analysis for revision of Joint Operations Graphic■ 

(Radar) and Target Charts. 

C. Obllguity Constraints 

10. For high prlarity areas and those with billy or mountainous terrain, MCIG requirement• limit photo obliquity to 45°. In fiat 

areas, and areas -..·here only small acale map• and charts are required. 

photographs with obliquity of up to 60° cnn be ueed for MClG purpose■• 

D. Ti.me SensitivitI 

11. Only when crises ariae in areas where map coveraae ie 

lnaufflcient and imagery is lackina; i• it necesaary to levy special MCIG 

t-equirement• with short deadlines. Normally DMA production planning 

procedures permit relatively long range advanced scheduling and increased

of once-over metric: imagery coveraae. Thia la essentially a worldwide 

requirement -- with the exception of certain ice-covered areas such as 

the interior of Greenland and Antarctica, and l.Z million square nautical 

mile• of the U.S. which are well surveyed and mapped. The 37 million 

tlOt:a1 does include 1. 6 million square nautical milea of the U.S., which is 

alao a U.S. Geological Survey requirement. 

13. The 37 million fiaure initially was &ubdivided into 

four aeneral pricrity categories. Priority 1, for example, included the 

hiahly developed areas of the Sino-Soviet area and Western Europe. In 

September 1973 DMA re-prioritized the 37 million mile requirement into 

five categories. By utilizing a combination of ex.iatina; KH·4B and KH-9 

panoramic materials, and def erring production in low priority areas, 

DMA indicated that the collection of 11. 0 million miles could be def erred 

temporarily -- thii!,t is, until after FY 78 -- with low riskY • The original 

total requirement of 37 million suqare nautical miles of stereo, 90 percent 

cloud-&C!e imagery was reaffirmed as valid for the longer term. 

14. Current Status of Collection. Tables 6 and 7 summarize 

the current statu• of collection •i•inst MCltG metric requirements. They 

show in detail the currerit requirements divided by major world areas and 

by priority. The attached world map (Fia;ure 1) shows the requirements 

specifically levied for Mis ion 1208 collection. This map shows by various 

color• the five levels of MC•G collection priorities. Priority 5 designates 

the approximately 11 million square nautical miles of temporarily deferred 

areas. The irregularly-shaped white strips within the colored areas 

indicate the amount of MCS coverage for military and civil MCa.G needs 

•atlafied prior to Mission 1208. Collection priorities reflect the current 

importance of the variot1s areas to map production programs and may 

chan1• from misaion to mission. 

15. E•tlmated 1978 Sati•faction Levels. Table 8, which 

i• ba•ed on the May 1974 NRO simulation, shows the estimated coverage 

which can be achieved. with the remaining nine MCS up to Mission 1216.

16. This elmulation aasumed a continuation of two KH-9 

MCS mission■ a year of 60 days each, of current film load■, and of the past 

record of succe•• in launch and recover of missions. It is under tood that 

the po aibilities of increasina the MCS film load by 20 percent and of 

extendina MCS mission life from the current 60 days to 90 days are beina: 

studied by NRO to determine whether the increased coverage obtained 

would warrant the expenditures fol'. these modifications. Initial simulation 

result■ indicate the impact of these two· measures will be rather limited. 

17. Thi• simulation shows that, by focusing collection only 

on Priority 1 through 4 requirements, which totalled 21. 9 million quare 

nautical miles, the remaining: KH-9 missions would yield 15.2 million 

square nautical miles. This would leave a balance of about 6. 7 million 

qua.re nautical miles shortfall in the higher priority requirementa. Of 

this shortfall an estimated 1. 6 million square nautical mile• i• in the 

Sino-Soviet area. 

18. The temporary deferral of 11. 0 million square nautical 

miles of the original total of 37 million square nautical miles tend• to 

reduce the collection efficiency of each MCS mis&ion -- both because 

the total requirement decreases and the rcmainina areas become amaller 

and more fraamented. 

19. tlmated Post-1978 Sati faction Level■• The NROestlmated post-FY 1978 shortfall of approximately 16. 9 million quare 

nautical miles requires metric coverage of varlou■ degree■ of accuracy, 

some of which at present can be satisfied only by the MCS. Lower dearee■ 

of accuracy can be satisfied by the exlsting data bank provided by the 

already collected KH-48 materials. One altemattve to preclude a sap in 

metric capability to meet the still-remaining requirement -- and to ensure 

havlna a metric capability to meet the potential increaae in MX positioning 

accuracy requirement ag:ain1t Category l taraet■ in Communiet areas --

would be to obtain additional MCS. To fully satl1fy the potential increased 

tarset accuracy requirement, an improved KH-9 vehicle po1ltionin1 

capability would also have to be available for these additional MCS. Other 

pos ible alternative• include the development of (1) a metric pan camera 

system, or (2) a metric capability for the KH-11 -- both of which must be 

demonstrated to be technically feasible.

20. USIB - Approved. The current USIB-validated KH-9 

panoramic requirement is shown in Table 9. Thia requirement both extends 

the base of worldwide coverase besun in the KH-4 missions, and includes 

annual recoveraae to μpdate MCIG products. The collection parameters 

are for 90 percent cloud-free coverage, in •tereo, taken at no more than 

45° of obliquity for target cluster•• and no more than 6d' obliquity for 

the remaining areas. Thi• requirement wa• not subdivided into priority 

areas: however, the compilations of pan requirements submitted for each 

KH-9 mi•sion are prioritized. 

21. Th••• USIB-approved MCIG requirements exclude the 

hlah priority Sino-Soviet area ince MCIG needs on this area are routinely 

satisfied by panoramic photography collected in response to lntelliaence 

Community requirements. The standing KH-9 panoramic intelligence 

requirements provide virtually complete coverage every two years of the 

entire Sino-Soviet area and impo1;tant areas of the Middle East . 

22. Current Status of Collection. Table 10 summarizes 

the current status of collection against the USIB-approved KH-9 pan. 

requirement• for MCIG. This table excludes both the Sino-Soviet area and 

the most important part of the Middle East, for which MCIG requirements 

are fully met by standing intelligence requirementa for periodic coverage. 

The !ollowin1 map (Fiaur• 2) shows by variou■ color• the four levels of 

MCIG collection prioritie• that were eatabli•hed for panoramic collection 

for Mi• ion 1208. 

23. Estimated 1978 Satisfaction Levels. The extrapolation 

in Table 11 of pan collection by Missions 1208 through 1216 is based on 

the pre ent allocation of about 8.000 feet of I0{-9 pan film per mis ion 

for military MCI.G. the current film rewind rate. a continu:ition of two 

KH-9 mission• a year, and a continuation of the pa t record of aucce11s in 

launch and recovery of missions. Thi■ extrapolation would more than fulfill the remainlna pan recoverage requirement. Whether or not the KH-4B 

covered areas are included in the first-time requirement. there would 

atlll be an tima.ted shortfall of about two million. Of course. a somewhat 

better collection performance could be achieved by additional allocation.a

of film for MClG purposes. It is assumed that the remaining USIB-approved 

USGS requirement for first-time panoramic coverage of the U.S. will be 

e•sentially fulfilled by 1978. 

24. Estimated Post-1978 Satisfaction Level ■• After FY 1978 

military MClG panoramic: requirements will consi•t of 2. 0 million •quar• 

nautical miles of recoveraae annually of areas previously photographed to 

permit the revi•ion of out-of-date maps and cha.rt•. Areas covered and 

their priority would vary from mi•sion to mia•ion depending on the revision 

cycle on map• and chart• in each part of the world. It ls •••umed that 

MCIG needs for periodic recoverage of the Sino-Soviet area will continue 

to be met by intelligence requirements for coverage of this area. In 

addition, the poat-FY 1978 requirement would include the shortfall of 

about two million square nautical miles of first-time covera.ae. On the 

ba i• of current collection rates. most of the 2. 0 million square nautical 

miles of panoramic recoveraae required annually for military MCIG 

requirements could be met. 

C. Non-Metric Hl&h Resolution 

25. Mllitary mapper• have requirements for non-metric 

hlah re olutf.on imaaery of •mall areas •uch as is now provided by the 

KH-1 y•tcm. The imagery is used for complllna large scale product• 

•ucb as port and harbor charts, airfield information, and city maps. The 

orlalnal KH-8 military MCIIO requirement totalled 3.176 tar1ets scattered 

throughout the world as followa: Sino-Soviet area - 559; remainder of 

Eurasia - 1,078; North America - 107; South America - 413; Africa - 796; 

and Au tralia/Oceania - 1!53. Of thi• total the KH-8 mls•lon• &om 1968 

throuah October 1973 have collected im•a•ry on 2,179 targetll, leaving 

a remainder of 997 to till be collected. Only a very small percentaae 

of the KH-8 capability has been used for military MCliO purposes. 

26. On occa lon such hiah resolution imagery has alllO bffll 

required for U.S. civil appllcatloas, but the total magnitude of th••• requirement• baa been even less than the military requirement•. 

27. It ls therefore reasonable to believe that the future collection re ulta agat.n t the•• hlah re•olution imaaery requirement• on mall 

areas will probably continue to be hl1~, tf not fully, ■■tl factory -- unl••• . there ls some unexpected marked lncrea e ln the level of requirement■•
