ABSTRACT

This project is based on the use of geospatial techniques for precision farming. Precision farming

is an approach to farm management using information technology which gives plant actual

information it needs for its optimum productivity and health. To enhance any farming production

and activities, precision farming is needed. Weather affects plants a lot in agriculture, in other to

know the actual weather information (map, wind speed, sunrise and sunset) needed on crop for its

healthy production, siting a farm house, and so on; precision farming/agriculture is a need for

adoption. Based on this, there was a need to develop an android application that will predict

current weather and get its information; basically (maps, wind speed and sunrise and sunset) based

on the user’s current location. The implemented package was tested on available mobile devices;

and analyzed how the mobile application developed can be used to enhance precision farming and

help the farmers boost their output.

To achieve this, the thesis focus on how geospatial data is collected, analyzed and used in the

decision making process (decision support system) to enhance agricultural productivity on yields.

To make this successful, geospatial data, an agro-meteorological monitoring application using

geo-spatial techniques for precision farming was developed. The growing of plant is important

where weather environment is favorable to crop for good harvest, because some crops need to be

protected against unfavorable weather condition from time of sowing to harvest time. The use of

this application developed enables the farmer or the user of the application to have the knowledge

and idea in order to make wise decision on which crop to plant on the farm from the data obtained

from the app developed for wind speed and sunrise and sunset in Ekiti State. Statistical tools used

to analyze the data were ANOVA and chart which shows the results are at variance and this is due

to the location of the Automatic weather station because some sited theirs around river, hill, snow,

farm land e.t.c.

1. INTRODUCTION

As the world's population grows, farmers will need to produce more and more food. Yet arable

acreage cannot keep pace, and the looming food security threat could easily devolve into regional

or even global instability. To adapt, large farms are increasingly exploiting precision farming to

increase yields,

In the past, precision agriculture was limited to larger operations which could support the IT

infrastructure and other technology resources required to fully implement and benefit from the

benefits of precision agriculture. Today, however, mobile apps, smart sensors, drones and cloud

computing makes precision agriculture possible for farming cooperatives and even small family

farms.

Every year copious technologies have been applied by many researchers, agronomies, scientist and

engineers to increase agricultural production with low cost, but it has adverse impact on

environment. Precision agriculture deals with the study of the application of technology to improve

agricultural practices as compare to conventional agricultural method and lower adverse impact on

environment. Remote sensing technology plays an important role in precision agriculture and its

application in the precision agriculture introduces new opportunities for improving agricultural

practices. With the help of global positioning system (GPS), it is possible to record field data

(slope, aspect, nutrients, and yield) as geographically latitude and longitude data (bonvioganmi and

lowenberg-deBoer, 2004; Roberts et al., 2004; Torbett et al., 2007; Watson et al., 2005).

It has capability to determine and record the correct position continuously, so therefore, it can

create a larger database for the user. For the further analysis, geographic information system (GIS)

is required, which can store and handling these data. This thesis highlights about remote sensing

technology, GIS, GPS and give you an idea about, how it can be valuable in precision agriculture.

Accurate and timely information is necessary to evolve strategies for sustainable management of

natural resources. Today’s “Space Age” supported by computer and communication technologies

offer great scope for efficient planning and management of agricultural resources on scientific

principles. The satellite data hitherto was considered as sensitive and used mostly for defence

purposes. However, the space scientists are now willing to share the satellite data, although on a

high cost basis, for civilian use.

For the precision farming, remote sensing (RS) and geographic information system (GIS)

technologies have been great of use to planners in planning for efficient use natural resources.

Also, agricultural meteorological encompasses meteorological, hydrological, and biological factors

that have an effect on agricultural production. It is also concerned with the interaction between

agriculture and environment. Agro-meteorological method therefore uses information and data

from different key sciences such as soil physics and chemistry, hydrology, meteorology, crop and

animal and others. For examples, new method for spatial applications involves GIS and remote

sensing for spatial data presentation and generation.

There is a need of knowledge and skill on how to transform, through geographic information

system (GIS), data collected by different sensors and geo-spatial into maps to provide on crop

physiological status and soil condition status.

Therefore, a development of an application for an android software was done in which its work is

to give exact and accurate information of map, wind speed, sunrise and sunset.

In this research android mobile application software that will be able to predict the actual and get

the correct weather information to make farming system easy was developed and tested.

2. Precision Agriculture (PA)

Precision agriculture (PA), satellite farming or site specific crop management (SSCM) is a farming

management concept based on observing, measuring and responding to inter and intra-field

variability in crops. Perhaps the easiest way to understand precision agriculture is to think of it as

everything that makes the practice of farming more accurate and controlled when it comes to the

growing of crops and raising livestock. Precision farming allows the precise tracking and tuning of

production. Precision farming makes farm planning both easier and more complex. This support the

IT infrastructure and other technology resources required to fully implement and benefit from the

benefits of precision agriculture. Today, however, mobile apps, smart sensors, drones and cloud

computing makes precision agriculture possible for farming cooperatives and even small family

farms.

2.1 Wind speed

Wind speed is the speed of the weather related air movement from one place to the next. Wind

speeds usually mean the movement of air in an outside environment, but the speed of movement of

air inside is also important in many cases, including weather forecasting, aircraft and maritime

operations, construction and civil engineering. High wind speeds can cause unpleasant side effects,

and strong winds often have special names, including gales, hurricanes, and typhoons. The highest

wind speed ever measured on earth, 231 miles per hour, was recorded on Mount Washington (New

Hampshire). You can measure wind speed and wind direction with a variety of wind vanes and

anemometers (wikipedia.org).

2.1.1 Importance of wind speed to agriculture

Wind speed has great benefit on agriculture, some of which are stated below:

• Wind increases the turbulence in atmosphere, thus increasing the supply of carbon- dioxide

to the plants resulting in greater photosynthesis rates.

• Wind alters the balance of hormones.

• Wind increases the ethylene production in barley and rice.

• Wind decreases gibberillic acid content of roots and shoots in rice.

• Nitrogen concentration in both barley and rice increase with increase in wind speed.

2.2 Sunrise and Sunset

Sunset colours are typically more brilliant than sunrise colours, because the evening air contains

more particles than morning air. Sunset occurs when the upper edge of the Sun – called the upper

limb sinks just under the horizon; sunrise occurs when the upper limb rises just above the horizon.

Sunrise or sun up is the moment when the upper limb of the sun appears on the horizon in the

morning. The term can also refer to the entire process of the solar disk crossing the horizon and its

accompanying atmospheric effects.

Sunset or sundown is the daily disappearance of the Sun below the horizon due to Earth's. The time

of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below

the horizon.

2.2.1 Importance of sunrise and sunset to agriculture

Sunrise has great benefit on agriculture as stated below:

• Solar energy provides light required for seed germination, leaf expansion, growth of stem

and shoot, and flowering, fruiting and thermal conditions necessary for the physiological

functions of the plant.

• Solar energy plays an important role as regulator and controller of growth and development.

• Solar radiation also influences assimilation of nutrient and dry matter distribution.

2.3 Basic Programming

A program is a set of instructions written in a language (such as BASIC) understandable by the

computer to perform a particular function on the computer.

Programming languages are artificial notational languages created or developed to be used

in preparing coded instructions on the computer for later execution by the computer. When

programming, we relate directly to the computer and also coding the software application to be

developed. There are two types of applications: (a) System applications: these are applications

embedded on a system (phones) e.g. calculator, message, radio, etc.

(b) Software applications: these are basically installed for personal use, e.g. AutoCAD, PowerPoint,

etc.

2.4 Applied Geospatial Techniques

Geographical Information Systems (GIS) links location based information (spatial) to database

information (tabular) enabling the user to visualize patterns, relationships and trends. This means of

analysis grants a new perspective to information, which is practically absent from exclusively

tabular data. Using GIS, we can manage, analyze, query and interact with geographically

referenced information using Spatial Analysis techniques. Spatial Analysis itself is the study of the

distribution and clustering of events and/or objects in space, in conjunction with their attribute

characteristics.

Geospatial Techniques. Geographers employ a number of different techniques for collecting,

studying, and analyzing spatial data. These techniques include both quantitative and qualitative

approaches, while also stressing important computer-centered technologies. Geospatial techniques

together with remote sensing, geographic information science, Global Positioning System (GPS),

cartography, geovisualization, and spatial statistics are being used to capture, store, manipulate and

analyze to understand complex situations to solve mysteries of the universe.

Geographical Information Systems (GIS) links location based information (spatial) to database

information (tabular) enabling the user to visualize patterns, relationships and trends. This means of

analysis grants a new perspective to information, which is practically absent from exclusively

tabular data.

3. METHODOLOGY

This work started on the premise of the previous work done in 2016 by Akerele et al., (2016).

These authors have successfully developed Gumbel Mathematical model for predicting

meteorological data in agriculture.

3.1 Development of an Android Software Application

This is the process by which new applications are created for devices running the Android

operating system. Officially, apps can be written using Java, C++ or Kotlin using the Android

software development kit (SDK).

But in this case, java programming was adopted using the Android software development kit

(SDK) as shown in Plate 1. The Android software development kit (SDK) includes a

comprehensive set of development tools. These include a debugger, libraries, documentation,

sample code, and tutorials. Currently supported development platforms include computers running

Linux (any modern desktop Linux distribution), Mac OS X 10.5.8 or later, and Windows 7 or later.

3.3 The Development Step Using Android Studio

In order to complete the development action for the app, the followings were considered:

(i) A weather API key was gotten from the openweathermap which is an online service that

provides weather data, including current weather data.

(ii) After this API key was gotten, it was parse into the java programming used in order for the

android device debugging, this was done; enabling USB debugging in the developer options was

done by enabling the developer options.

Note: A developer mode in Android phones that allows newly programmed apps to be copied via

USB to the device for testing and a gps enabled phone with internet permission.

The following activities were developed in the android studio which each has enabling functions;

• Get location: this shows the latitude and longitude of exactly where the user is with the help

of the enabled GPS on the device alongside with the java programme language.

• Weather information: this is also shows the weather information of the location of where the

user is, which works together with latitude and longitude, and also with the help of the

registered agriculture API gotten from the openweathermap. The java language

programmed weather information is wind speed, sunrise and sunset.

• Map: this shows the exact map of the location where the user is.

On android studio, the Google map activity was chosen, this activity enables to be able to view real

time map on our device alongside the user location. The map activity code was written as well.

The above was done in the android studio in which each of the above button code was written and

in java programming language.

3.4 Layout

A new android project was chosen in the android studio where Application Name was changed to

"ABE one”, Company Domain: "example.com", preferred Android version was chose like API: 16

Android 4.1 (Jelly Bean), while maximum and minimum SDK was chosen. After all this has been

done, it should be in this following files; app > java > com.example.ABE one> MainActivity.

3.5 Editing the Manifest

The app will need a permission in which the next activity will be able to function, because we are

getting our data online, internet permission will be needed, to edit the manifest, go to app >

manifests > AndroidManifest.xml

The only permission this app needs is android.permission.INTERNET, and the java code was

written to enable internet permission.

4. RESULTS AND DISCUSSIONS

4.1 Results

an average of 3.36m/s wind speed for the application developed, 3.26m/s wind speed for

yandexweather, while 4.95m/s for freemeteo.

In the month of August, the android mobile application developed has an average data of 3.79m/s

wind speed for the first week, 3.28m/s for yandexweather and 4.43m/s wind speed for freemeteo.

For week 2, the mobile app. developed has an average data of 3.33m/s wind speed, 3.3m/s, and

3.84m/s for freemeteo. For week 3, the android mobile application developed has an average data

of 3.49m/s wind speed, 3.34m/s for yandexweather, and 5.74m/s wind speed for freemeteo.

For the last week for month of august, the android app developed has an average data of 3.27m/s,

3.15m/s for yandexweather, and 4.83m/s for wind speed.

For the month of September, in the first week, the app has an average of 3.57m/s wind speed, while

yandexweather has 3.15m/s wind speed, and 4.16m/s for freemeteo. For week 2, the app has

3.07m/s, 3.28m/s for yandexweather, and 5.09m/s wind speed for freemeteo. For week 3, the app

developed has an average data of 2.57 m/s wind speed, yandexweather has 3.21m/s, while

freemeteo has 4.17m/s wind speed. Week 4 has an average data of 2.86m/s wind speed for the

application developed, yandexweather has an average data of 3.35m/s wind speed and 3.85m/s

wind speed for freemeteo.

For October, the application developed has an average number of 2.52m/s wind speed, nimet has

the average data of 1.24m/s wind speed, yandexweather has 3.25m/s, freemeteo has 4.63m/s win

speed. For week 2, app developed has 3.30m/s average wind speed, NIMET has 1.75m/s,

yandexweather has 3.25m/s wind speed, freemeteo has 3.35m/s wind speed. Week 3, the app

developed has 2.48m/s average wind speed, NIMET has the average data of 2.66m/s wind speed,

yandex has 3.54m/s, and freemeteo has 4.75m/s wind speed. Week 4, the app developed has the

average data of 2.69m/s wind speed, NIMET has 1.34m/s, yandexweather has 3.4m/s, and

freemeteo 3.80m/s average data for wind speed.

For the ANOVA Table, The significant value or the statistical difference between the groups

(ABE-Openweathermap, yandexweather, and freemeteo) which is represented as p-value is 105E-

13, which is lower to the alpha level (0.05) for test for differences, and also the f-statistic is higher

than the f-critical, with this, there is a significant difference between the groups and null hypothesis

can be rejected. Therefore, the differences between the mean are statistically significant because the

p-value is less than or equal to the significant level (0.05).

For correlation Table, the correlation between the obtained data from the application developed

from the registered agriculture api key (openweatherMap) and yandexweather is 0.010827.

Technically there is a positive correlation between the two, the relationship between the variables

are weak.

Also, the correlation between the data obtained from the application developed and the data

obtained from freemeteo is 0.086045. Technically there is a positive correlation between the two.

With all the results shown from Figure 2 to Figure 6 from the graphs above, for the month of July,

there are little variance from the average data gotten for each weeks with the other data gotten from

other automatic weather stations for wind speed.

Same variance applicable to the month of August, September and October, the cause of this little

variance was due to where the automatic weather stations were sited at different locations, i.e. some

automatic weather station were located on hill, some at the river banks, some on snow area, while

some on a dry land, and so on. Therefore the wind speed, the sunrise and sunset data obtain from

different automatic weather station location will be at variance, so for the data obtained from the

weather stations in comparison with the weather information obtained from the application

developed are so close to each other.

The android mobile application developed has performed its function in enhancing precision

farming, thereby providing accurate information which the farmer need on the farm in other to

ensure smart farming.

5. CONCLUSIONS AND RECOMMENDATIONS

5.1 Conclusions

The application that get current weather information basically for wind speed, sunrise and sunset

and map for ado Ekiti in which the average data of the weather information will be obtained has

been developed.

The developed android application is a decision support tool (will give a solution to this problem)

and it is also a current technological advancement free API service and location based mapping

services with low cost sensing capabilities. It will provide correct details for the sunrise and sunset

and wind speed.

The application has been tested on an android mobile device; the application was developed to

work on an android device, which works well on the android phone tested with. The use of this

mobile application will encourage youth to go into agriculture, enhance and boost farmers’ crop

productivity, because this application is a concept of precision farming.

Precision farming is about an approach to farm management which uses information technology,

that gives precise information about what crop or plant needs for its optimum health for better

agricultural production.

This work shows the significant effect of the development of the android mobile application,

enhancing and encouraging farming in a modernized way because it will make it easier for farmer

to be able to study and know the specific and correct weather data and all other things incorporated

to farming system.

With the use of this application developed, it will allow farmers to make a wise decision on their

farm land, on what to plant, for siting of their poultry house, pig pen and other farm activities

because the two parameters of weather in the case plays significant roles.

5.2 Recommendation

Based on the findings and the results of this project, farmers who face problems on their farm based

on irregular or poor yield of their crops should adopt a precision farming method so as to boost

their crops yield and enable the farmer to make wise decision and engage in smart farming.

This project serves as a basis for which agricultural methods and practices can be enhanced using

computer which is a common, efficient and flexible machine relatively useful in agriculture and

other meteorological related fields, as well as geo-spatial techniques which is widely becoming a

very useful tool in every developing sector.
