I G"NR LIT"S
On the "type I R-E.ort" which corresponds to the Jiun-October 1972
period within the sphire of the objectives of the "itTS Program,
it was promulgated th' preparation of photomaps at difernt scales,
with the objective of evaluating thn geom-tric raSolution which was
the "RTS imagery prosented by "RTS volume, forth* preparation of the
first phisical pam of Bolivia, once that the entire images of the
country was completed.
As a result of this planning the first "Space Photomap" of th- Sucra-
Bolivia zone was prepparnd, utilizing th- "RTS-1 imagery which corres-
ponds to the section, as an fxperimntal new provisional cartographic
product.
The "Space Photomap" includes part of the Sn-19-12; SPr-20-9; S'-19-16
and S1-20-13 sh ets of the CUTM distribution, corresponding to the
Bolivian Republic, reproduced at an approx imate scale of 1:250,000.
II. M"THOD OF WOdK:
For the elaboration of this first ,Spacen Photomap" of the Sucre region,
we utilized 'arts of the 7-1008-13522-1 imagery of the RBV system,
which was amplified in two parts: the first one, the format 70 x 70 mm.
to 23 x 23 cm., obtaining as a result the 1:1,000.000 scala, and later
passing to 1:250,000 scale. Forthis purpose, we utilized the controls
available on the Sucre and adjacent sheets, which consists of a deter-
mined cartometric positions, localized in photoidentified cartographic
details.
The specific projections are ones utilized in large scales. in this
work we utilized the CUTM, as well as a series of squares according to
the MT-5241-1 specifications; the marginal datum according to the model
sheet TPC-25-50-100 with some modifications corresponding with the
reproduction of impresion colors and with "Intensified colors" in
accordance with the I.P.G.M.'s publication No. 321. Space Photomap of
the Sucr^-Bolivia region - YRTS PROGRAM - Bolivia (Cont'd).
Il. CONCLUCIONS:
The present cartographic productions was completed as an exppriment.
That is the main reason why the present photomap has marny errors In
its representation, among them is the lack of relation between the
distribution of sh-e ts at an 1:250,000 sealo; the quality of the
reproduced imagery is not perfect: the format has to be studied again;
the assigned colors werw put on the dry zone, and the pre^n color
was operput on the regon covered by xerophile v^gtation.
All of these errors will be considerd for th- next new map production.
Due to the forementioned facts, the cartographic sub-program, the
pertinent studies concerhing MRTS imagery processed by precision has
been realized, that is to produce a new "Space Photomap" which will be
reproduced with the use of the three RBV bands, utilising the system
of "Irregular Small Points".
Once thmsp an future problams that tmay appnar in tho present inves-
tigations are resolved, we can draw tho conclusion that tha "RTS
Imag ry can be an -xcallont product applicablo in cartography
Uwhpn onn applies rnsprctive control of the grohndpoint.
