Chapter I
INTRODUCTION

A century ago almost all maps were printed on paper. With advances in technologies we now find maps in any other formats. Mapping activities are on the rise as more and more data become available and computer software takes over the tasks of processing the data. The methods used for creating maps have changed dramatically during the past ten years. The map production process consists of several discreet components from an initial design concept through the completion of the map in its final form.

The functionality of maps has been greatly advanced by technology. In electronic maps having local information within the map allows more efficient analysis and better decision making. Usually traditional maps are used for general reference but in our digital world many local and regional governments maintain databases for the storage of information. In this environment maps are generated as they are needed because the database is updated constantly.

Information System (IS) is a part of the development of electronic mapping nowadays. IS are set of components for collecting, storing, and processing data and for delivering information, knowledge, and digital products. Hence, mapping system is said to be classified as a Geographical Information System (GIS).

A Geographic Information System, or GIS, is an organized collection of computer hardware, software, geographic data and functionality, accessed by the GIS user capture, store, update, manipulate, analyze, and display all forms of geographically referenced information. GIS allows us to view, understand,

question, interpret, and visualize data in many ways that reveal patterns and trends in the form of maps.

Making decisions based on geography is basic to human thinking. Where we shall go, what will it be like, and what shall we do when we get there are applied to the simple event. By understanding geography and people’s relationship to location, we can make informed decisions about the way we live on our planet.

1.1 Background of the Study
The barangay is the smallest administrative division of our government and the barangay officials are the first unit responsible for their constituents. Municipalities are the urban local governments that deal with civic functions and local development functions in the municipal area. In order for them to give the necessities to their jurisdiction, usually they are conducting mapping and survey within the area. As for the duties of barangay officials they are responsible for giving the information needed by the local government.

Taguig City under the administration of Mayor Lani Cayetano, recently, initiated the integration of Geographic Information System (GIS) and Business Mapper into their Survey System. The goal of the said GIS integration into Taguig’s survey is to facilitate business licensing, assessment, zoning, public safety and crime mapping, urban planning, health disease mapping, risk assessment management, and many other uses. House to house survey is conducted to gather information needed and drawings of map to locate houses are done manually by the enumerator of the barangay. As the requirements are completed transferring of all gathered information are forwarded to the local government.

For the enumerator of the barangay who does the fieldwork of survey and mapping, usually problem occurs when collection of data is kept manually. If there is only a system that will provide them to collect data and storing of files using technology, then it will be easier for them to update such records and transferring of records in a possible secured way.

The proposed system is an Electronic Mapping Information System wherein it has a collection of map images, information, and methods that process data and make it available for Graphical User Interface (GUI). The system is classified as Geographical Information System (GIS). On the computer screen, map users can scan map in any...
