Abstract: Land boundary map and land contour map for large scale areas are very difficult to obtain, because these

maps in a certain area have not been made or are not owned, while the initial planning can be done without

having to wait for all these requirements to be available, such as time constraints, cost, weather and ground

measurement equipment. To quickly get a map for planning the development of tourism accommodation at

the Tukad Banyuraras estuary in Kalisada Village, Seririt District, Buleleng Regency, Bali, a map of land

boundaries and land contours was made from processing satellite image data using the Quantum Geographic

Information System (QGIS) software application and ground control point using the Global Positioning

System (GPS). Certain objects such as beaches, rivers, roads, houses, rice fields, gardens and others that were

previously in raster format in a satellite image are converted into digital format, the suitability of the name of

the element according to the object/element being plotted, drawing lines according to image appearance. The

land boundary before deducting the coastal and river borders obtained an area of 194,666.8496 m2 or

19.46668496 hectares. While the land boundary after deducting the coastal and river borders obtained an area

of 144,819.7910 m2 or 14.48197910 hectares.

1 INTRODUCTION

Indonesia is an archipelagic country consisting of a

land area of 1,922,570 km2 and a water area of

3,257,483 km2, thus requiring the government to

continuously carry out development for the benefit

of the population in Indonesia. This development

activity cannot be separated from a form of spatial

use

at the district, city, sub-district and village

levels. Of course, the use of space in the vast

territory of Indonesia must be supported by good

spatial

planning. One of the planning steps is to

prepare

geospatial information in the form of maps

of land boundaries and land contours needed for an

activity in space utilization (Rumampuk, 2013).

In the current era of development, to direct

development by utilizing regional space in an

efficient, effective, harmonious, harmonious,

balanced and sustainable manner in order to improve

community welfare and security and defense in

accordance with the mandate of the law, it is

necessary to prepare a Regional Spatial Plan. One of

the components of the Regional Spatial Plan is the

development of residential areas. As a proper

development planning effort, especially the need for

spatial data to support settlement planning, it can be

obtained quickly, cheaply but accurately, using high-

resolution satellite imagery (Parmadi, 2016).

Utilization of remotely sensed satellite images

for mapping activities is a common activity

nowadays. Spatial information presented in satellite

image maps is raster data sourced from the

continuous recording of satellite images. The stages

in mapping using the results of this sense are by

making a pattern using the sensed data which begins

with satellite processing with reference to ground

control points to limit the area to be mapped. One

example of the use of sensing technology for

activities in the field of mapping is for mapping the

coastal area at the Tukad Banyuraras estuary which

supports tourism accommodation planning activities.

Some of the advantages of mapping using remote

sensing technology include: results can be used to

map very large areas quickly, whereas manual

mapping is usually only used to map very narrow

areas, remote sensing technology is cheaper and can

2 RESEARCH METHODS

The research implementation is generally carried out

in the form of information collection (secondary and

primary data collection), field surveys, problem

analysis, and inventory formulation and performance

evaluation of digital data processing.The research

work steps are outlined in the form of a research

diagram that describes the complete stages from

beginning to end sequentially to the end with a

duration of one year of research. More research

flowchart can be seen in the figure 1:

Seririt District, Buleleng Regency, Bali).

Conducting field surveys, including among others:

Initial survey data collection

Data collection by measuring ground control

points in the field using the Global Positioning

System (GPS) tool

Data calculation and satellite image processing

2.1 Measurement of Ground Control

Points

Prepare the Garmin GPS 60 (Global Positioning

System) GPS device, including the completeness

of the battery to be used

Set GPS coordinates to UTM (Universal

Transverse Mercator) coordinates

Prepare an existing initial base map to make it

easier to find points in the field

Measure coordinates in the field so that UTM

coordinates are obtained (x, y and z)

The analytical work carried out includes analysis as

a whole. The analysis carried out includes:

Analysis of the tools used

Measurement analysis of ground control

points

Analysis of the accuracy obtained in the

digitization of the map

2.2 Research Sites

District, Buleleng Regency, Bali.

3 RESULTS AND DISCUSSION

3.1 The Result of Ground Control

Points

As for the results of the measurement of coordinates

with a GPS device, the ground control point data is

generated as shown in table 1:

Village, Bali

Research Site.

3.2 Data Input and Map Digitization

Before importing into QGIS, it is necessary to make

arrangements first so that the coordinate data from

the GPS as the Ground Control Point can be read by

the QGIS software. Coordinate data stored in excel

is saved to a CSV (Comma delimited) file type. The

satellite image used is ESRI Satellite and the next

step is digitizing the land boundary map.

3.3 Delineation and Calculation of

Land Boundaries

Based on the Bali Provincial Regulation No. 3 of

2020 concerning Amendments to Regional

Regulation No. 16 of 2009 concerning the Bali

Provincial Spatial Plan for 2009-2029, it is regulated

regarding the existence of a coastal border for the

estuary of the Banyuraras estuary, which is 100

meters from the high highest water level and

embankment river border for rural areas which is 5

meters from the edge of the river embankment

(Peraturan Daerah Provinsi Bali No 3 Tahun 2020,

2020). Elevation of high highest water level in this

area is 0.668 m (Wicaksono, 2020) From this

regulation, it is obtained that the land limit is

allowed to be built for tourism accommodation

purposes. The boundaries and land area in question

are:

3.4 The Land Boundary before

Deducting the Coastal and River

Boundaries

The land boundary before deducting the coastal and

river boundaries is 194,666.8496 m2 or

19.46668496 hectares. The shape of the land

boundary is as shown in figure 4 :

boundaries of beaches and rivers.

3.5 The Land Boundary after

Deducting the Coastal and River

Boundaries

The land boundary after deducting the coastal and

river boundaries is found to be 144,819.7910 m2 or

14.48197910 hectares. The shape of the land

boundary is as shown in figure 5:

Figure 5: The land boundary after deducting the coastal

and river boundaries.

3.6 Land Contour Drawing

From the DEM (Digital Elevation Model) data, then

adjusted to the coordinates of the research location,

the contours of the land are obtained with contour

intervals of 1 meter. Soil contour drawings will be

needed for cut and fill soil and for other planning

purposes. The resulting land contour images are as

shown in figure 6:

Figure 6: The land of the contour.

4 CONCLUSION

The conclusions of this research are:

1. The land boundary that can be used to build

tourism accommodation buildings is the land

boundary that has been cut off by the beach and

river borders. The land boundary after deducting

the coastal and river boundaries, we get an area

of 144,819.7910 m2 or 14.48197910 hectares

2. The resulting land contour map is with a contour

interval of 1 meter, where the contour map can

be used for spatial planning purposes and cut and

fill the land
