Indonesia, are mentioned for their huge contributions.
2 DISCUSSION
To compare between image and map in the same format of
presentation is not easy part of work. Indonesian Atlas from
Space is one of the BAKOSURTANAL’s product to provide
information on general object of national geographic features in
the same format. The atlas serves both on image and map. By
using this Atlas, reader or user can check directly and appoint
where the area need to be obtain its information.
Atlas Indonesia from Space use several sources of data. High
and medium resolution satellite images provide pictures of
tourism objects from space; map served as direction to the
tourism object locations; text/ narrations help in explaining
tourism objects how to reach them as well as provide
information on the type of available facilities; and various
photographs in supporting Atlas with further detail beautiful
pictures of tourism objects.
Displaying of satellite image tries to show real condition of
interesting places. The view of images presents the tourism
objects from satellite where the user can be known exactly how
the real location about the object will be visited. Most of the
images was taken by oblique system, hence it is still hard to
know more clearly about the tourism object. Nevertheless,
generally view can be known. To support the visualization of
satellite imageries in displaying tourism objects, some terrestrial
photographs may be needed, make this atlas presentation more
detailed and better picture. Meanwhile, topographic map is
commonly used to help readers in understanding the interesting
places. Information completed with narration about the objects
will also assist reader to reach the objects. As shown on Figure
1 as a sample of tourist objects in Sumatera (Toba Lake)
visualized by both satellite image and map.

2.1 The Process of Making the Atlas
The process of making of Atlas Indonesia from Space can be
divided into 4 parts: preparation, data compilation, data
processing and data presentation.
1. Preparation.
This stage of activities involved preparation of base map,
inventory of potential tourism objects, identification of
tourism objects location on the map, preparation of field
survey, determination of interesting places and providing
of satellite imageries.
2. Data Compilation.
The use of data for making this atlas consisted of primary
and secondary data. Primary data was acquired from field
survey including geographic coordinates, photograph and
video recording of tourism objects and related information.
Meanwhile, secondary data were derived from government
institution (i.e. Office of Tourism Department).
3. Data Processing.
Data processing was done with the following steps:
a. Image joining (fusion), image enhancement and image
cropping,
b. Photograph processing such as enhancement, brightness,
contrast, etc.,
c. Map preparation for administrative location of object
tourism,
d. SRTM imageries processing for Indonesia islands and
administrative location of object tourism,
e. Textual narration to describe tourism objects.
4. Data Presentation
Satellite image, topographic map, photograph pictures and
narration were combined into one media. This presentation
or visualization had been designed (layout) with art and
design.
2.2 Visualization Analysis
This 260 page Atlas from Space actually contains 205 images,
10 aerial photographs, 152 maps/ topographic maps, 144 object
pictures and 153 texts, as seen in Table 1.
The ideal Atlas would be in balance composition among those
contents. By definition, Atlas is a collection of maps; therefore,
ideally, this Atlas should be predominantly presented in remote
sensing and cartographic visualization. At least, content
domination of remote sensing products could be accepted since
‘space’ as the theme of this Atlas.
Additional visual supports such as terrestrial pictures are needed
for describing and picturing the interesting point objects.
However, atlas as cartographic product will have a minimum
standard of map contents. It is understood that for the purpose
of tourist promotion, this atlas would be interesting product if it
provides more beautiful and sharp pictures. It will help in
promoting tourism. However, in the context of atlas definition,
those objects can always be represented by cartographic
symbols on maps. In fact, it isn’t sufficient for simple symbols
to explain any information for the readers. Again, to show more
understanding for the readers, terrestrial pictures are still be
required.
Presentation of images, aerial photos and maps are grouped as
cartographic content while terrestrial pictures and texts are
