Utilisation Of Mobile Technology For Field Data

Published Date: 02 Nov 2017

Developments in mobile technology and communication and the location-based services (LBS) sector offer new options to realise fast and cost effective field data management in the areas of land management and more specifically land administration.

To reduce the time needed to acquire data in the field by hand, returning to the office, processing the data and eventually return to the field to do the indispensable measurement adjustments for optimal results, the improvements in wireless technology and the LBS sector are beneficial. Data acquired in the field by a mobile fieldworker is transmitted to a remote system immediately using GSM or wireless LAN technologies. On the remote system, the data will be processed and the results will be sent back to the fieldworker in the same way. Depending on the capabilities of the remote system, the mobile fieldworker is able to integrate the knowledge obtained by the processed data into this current field operation instantly.

Data management will play a future role for future utilization of wireless technologies. The data, their collection and updating will be limitations for many possible applications. There exist big amount of potential applications and research in this field.

This project comprises an investigation into the utilization of mobile technology / mobile GIS for field data management in land administration. It reviews the use of wireless technology and Geographic Information Systems, in order to improve the quality of data management - land related information in land administration - in the field. It focuses on making processed data available to fieldworkers in the field.

The project consists of the following components:

Introduce and describe the use of mobile technology for data management in the field: Modern mobile technology and GIS techniques are combined in a complete revised updating methodology leading to a fully digital processing and management of the data.

Location based services in land administration fieldwork: Using new telecommunication technologies (e.g. GSM, GPRS and GPS) in combination with mobile devices (Personal Digital Assistant, Handheld), fieldworkers of land data and information will be supported in their daily work by receiving information in combination to the actual location via GPS or GSM.

Customising IntelliWhere OnDemand for wireless learning in land administration: Mobile technology can form part of the environment that mediates learning. By compiling a fieldwork procedure – collecting and managing data in the field – it is possible to educate/assist the fieldworker in the use of mobile GIS for wireless fieldwork.

Case study: Evaluating the use of mobile GIS in field data management and applying it to land administration in Hungary

Value of the study: Improve the quality of data management in the field and facilitates the development of wireless learning via mobile devices

Future research: Describe the use of mobile multimedia as new data collection and management techniques. This includes the use of voice input/recognition and digital imagery in the field.

The use of new mobile technologies in combination with mobile mapping devices offer new opportunities for the provision of high quality databases and their management in the field.

MOBILE DATA MANAGEMENT IN THE FIELDWORK CONTEXT

Data management is one of the four core components when working with geographical data. It includes those functions needed to store and retrieve data from the database. The methods used to implement these functions affect how efficiently the system performs all operations with the data (Aronoff, 1989).

Many wireless applications also need data connection with geographical information systems. Wireless technology offer new tools for data management, mainly for data collection and data updating in the field. Therefore data management can be more effective and also secure using wireless connection.

MOBILE DATA MANAGEMENT IN A LAND ADMINISTRATION CONTEXT

Land administration is more than just a data capture, storage, retrieval and display system but to be managed. The data that are recorded about land and property are not only a valuable resource in their own right; they are also something to which value can be added. Mobile technologies allow this fact to be recognised and exploited.

Modern portable pen computers (handhelds and PDAs) allow updating of (cadastral) maps during the field session and make geometric quality management possible in the field, so that detected errors can be investigated and rectified right on the spot. Data communication facilitates the transmission of work files of maps from the field to the office in order to establish an efficient work process.

PROBLEM STATEMENT

The most time consuming and expensive task in building a modern land administration system is the collection of new data and the conversion of old records into digital form. Data capture is not just a technical survey operation since there must be agreement on the ground as to what is being measured, who owns the land and where the boundaries lie. Although technology can help to speed up some of the processes of creating and updating a cadastral system, it is essential that land-owners are consulted and are confident in the results of any data acquisition programme.

The key issue is to get neighbours to agree on the ground as to who owns what land. Every boundary must be identified correctly and whereas a synoptic view may meet the needs of general land administrators, remote sensing techniques do not normally satisfy the requirements of land-owners or development control officers.

The crucial issue then becomes one of maintenance and the need of cost effective ways of keeping the data up to date, carrying out subdivisions or retracing old property boundaries.

On the determination side of the land administration process, the fast moving property market and public administration together with the fast developing IT world, have developed the need for more efficient and effective ways of data management, especially in the field. Land administrators need to manage the captured and revised data with the aid of wireless/mobile devices. It has to facilitate data management functions by means of download and uploading data to and from the device respectively.

Overall, new field working technologies have re-awakened the debate about appropriate standards of precision in measurement and how these standards should evolve over time, but the emphasis for fieldworkers has moved from measurement to the management of data in the field.

RESEARCH GOALS AND OBJECTIVES

There is a growing need for mobile data management systems, which are able to store, manipulate, retrieve, most importantly , manage the large quantities of geo-referenced data that are available today. Should land administrators decide to incorporate mobile technology as a tool for mobile data management in the field, it will have to add value to the overall strategic and operational management approach.

In view of the problem statement and research questions, the study will interpret the questions asked and motivate the benefits of using mobile devices in a land administration environment. The goals and objectives formulated are to:

Explain and describe the theory behind wireless technology, location-based services (LBS), land administration, and field data management.

Optimise field data management in land administration by using mobile technologies and LBS

Improve the quality of data management in the field

Effective and efficient data transfer from the server station to the fieldworker and back

Facilitate the development of wireless education in land administration

Customise mobile GIS software (IntelliWhere OnDemand) for faster and effective data capturing and management in the field

Describe the use of mobile multimedia as new data collection techniques in the field as a future research

RESEARCH QUESTION

Looking at the problem from a GIS perspective to support the data management process, it is possible to formulate the following research question:

How can land administration data best be managed in the field using mobile technology and location-based services?

Sub Questions

How can LBS support data management in the field?

How is data managed in land administration?

How can mobile technology together with LBS improve the quality of field data management?

What field data management procedures in land administration exists?

Is it possible to customise mobile software (like IntelliWhere OnDemand) for data management in the field?

RESEARCH DESIGN AND METHODOLOGY

TYPE OF STUDY

This study is designed as an exploratory investigation into the utilisation of mobile technology and mobile GIS techniques for field data management in a land administration. This implies that no hypothesis for the study will be defined. The study will be supported by a case study.

PURPOSE OF THE STUDY

The project will investigate and evaluate the use of mobile technology and location-based services for field data management in land administration and to facilitate the development of wireless learning in the field. It evaluates whether this new technology can be used for the specific purpose. The value added to land administration in Hungary will also be explored.

RESEARCH DESIGN AND METHODOLOGY

This research will involve doing a case study on only one study site in Hungary. I will consult with the Prof. Dr. Bela Marcus, director of the College of Geoinformatics, University of West Hungary. This study is particularly useful because I as researcher and also the land administrators lack a clear idea of the outcome and impact of new technology used in the study. Through the exploration one can develop concepts more clearly, develop operational definitions and improve the final research methodology (Cooper & Schindler, 2001).

The study will also include a data collection and data analysis phase. This research is designed to take in account whether there is a demand for a mobile data management in land administration fieldwork and can the new system function independently; will it be a value-added process? When designing a strategy framework and customising the survey process on the mobile devices, I have to consider the before mentioned criteria.

The research methodology that will be used comprises of the following steps:
