Possible Habitat of Firefly in Ube City using GIS

I. BACKGROUND

Firefly is a type of insect that can give off light clearly visible at night. Light is produced by

"cold light" which not containing ultraviolet or infrared rays and has a wavelength of 510 to 670

nanometers. The fireflies are included in the class which is a family of Lampyridae in the beetle order

Coleoptera. There are more than 2000 species of fireflies. Firefly is one of the most popular insects

in Japan. The purpose of this assignment is to know the area of firefly habitat in Ube city. The

fireflies habitat be divided by three category are within 500 meters from fresh water, more than 1

kilometers away from urban area and buildings, more than 50 meters away from road. To know the

area of firefly habitat is using ArcGIS program.

II. PROSEDURE ANALYSIS

The following will explain the procedure of data analysis to obtain the area of habitat of fireflies

in the city of Ube using ArcGIS.

2.1 Change the projection of coordinate system to the zone 52N of UTM

The original data is use coordinate system in WGS 1984. Ube city is located within the zone

52N of UTM. To change the coordinate system is using command “Project” in the Arc Toolbox.

Figure1. Coordinate system projection to the zone 52 of UTM

2.2 Boundary zone of each characteristic for firefly habitat

Make a buffer zone appropriate of each characteristic for firefly habitat. The characteristics of

firefly habitat are within 500 meters from fresh water, more than 1 kilometer away from urban area

and buildings, more than 50 meters away from road.

A. Buffer for open water/fresh water

To create buffer polygon for 500 meters from open water is using command “Buffer” in

the Arc Toolbox.

Figure2. Procedure of buffer for 500 meters from open water

Figure3. Result of buffer for 500 meters from open water

B. Buffer for urban area

To create buffer polygon for 1 kilometer away from urban area is using command “Buffer”

in the Arc Toolbox.

Figure4. Procedure of buffer for 1 kilometer away from urban area

Figure5. Result of buffer for 1 kilometer away from urban area

C. Buffer for buildings

To create buffer polygon for 1 kilometer away from buildings is using command “Buffer”

in the Arc Toolbox.

Figure6. Procedure of buffer for 1 kilometer away from buildings

Figure7. Result of buffer for 1 kilometer away from buildings

D. Buffer for road

To create buffer polygon for 50 meters away from road is using command “Buffer” in the

Arc Toolbox.

Figure8. Procedure of buffer for 50 meters away from road

Figure9. Result of buffer for 50 meters away from road

2.3 Creating layer a combination of roads, buildings and urban areas

Make become one the layer buffer of roads, buildings and urban area is using command

“Merge” in the Arc Toolbox.

Figure10. Procedure of merge for roads, buildings and urban areas buffer

Figure11. Result of merge for roads, buildings and urban areas buffer


7


After process of merge the layer is not become the one polygon. To make one polygon is

using command “Dissolve” in the Arc Toolbox.

Figure12. Procedure of dissolve for roads, buildings and urban areas merge

Figure13. Result of dissolve for roads, buildings and urban areas merge

2.4 Wedge between open water buffer with combination of roads, buildings and urban

areas.

To create an incision between open water buffer with combination of roads, buildings and

urban areas is using command “Erase” in the Arc Toolbox.

Figure14. Procedure of erase between open water buffer with combination of roads, buildings and urban areas

Figure15. Result of erase between open water buffer with combination of roads, buildings and urban areas


9


In the result of the slice for the open water buffer with combination of roads, buildings and

urban areas, some area are located in outside of Ube City boundary. To cut some area which

located in outside of Ube City boundary is using command “Clip”.

Figure16. Procedure of clip between the result of erase and Ube City boundary

Figure17. Result of clip between the result of erase and boundary of Ube City (Habitat area of firefly in Ube City)

Figure17 shows the area to live fireflies in the city of Ube. To find the area we need to create

new field in the attribute, the process can be seen in the figure below:

Figure18. Create new field in the attribute

Figure19. Calculate the area of habitat firefly

Figure20. Area of habitat firefly in Ube City

From Figure20 shows the total area of habitat firefly in Ube City is 48,837,400.00 m2.

III. HABITAT AREA OF FIREFLY MAP

Map of the area where fireflies live in the city of Ube made using six layers are open water,

roads, buildings, urban areas, Ube City boundary and habitat area of firefly. Map of the area where

live fireflies can be seen in Figure21.

IV. CONCLUTION

Firefly is the one of popular animal in Japan. The simplify condition they live in the three of

characteristics place are within 500 meters from fresh water, more than 1 kilo meters away from

urban area and buildings, more than 50 meter away from road. The total area of habitat firefly in Ube

City is 48,837,400.00 m2. The area of habitat firefly is about 23.34% of the Ube City area (Ube City

area is 209,204,501.89 m2).

GIS is very useful in various fields, given the variety of purposes will the information system.

GIS can be used to create maps of flood prone areas in a place. It required some basic data, such

as: land use, slope, soil type, topography, rainfalls and watershed conditions.
