1. Primary data is the data that is captured for the purpose of GIS itself and the data has not been use multiple time. For example, digital aerial photograph

Secondary data is the data that is captured for other purposes and it has been used multiplr times. For example, scanned map and photographs.

2. Data maintenance take a lot of time and effort, which takes time away from more important tasks. Keeping maps and spatial data up to date can be challenging, especially if multiple applications are being used and downtime is to be minimised. Accuracy and precision go hand in hand, and as accuracy and precision improve, so do the costs of collecting and storing the data. An aerial photograph with a 1-meter resolution, as an example, will be more expensive to collect and store (due to the higher equipment resolution) than one with a 30-meter resolution (due to the larger pixel volume). Neither high precision nor high accuracy necessitates the presence of the other kind of high precision. These are two different measurements that cannot be compared. The quality of GIS data is determined by its relative accuracy and precision, as well as the inherent error in both precision and accuracy.

1. Geodatabase will read all the errors in line and polygon. Set up the geodatabase either usign cluster tolerance, ranks from 1 to 5 and set the rules, for example: must not be intersect and must not be dangle. Error can be found by using Error Inspection tools. It have find errors for all rules, find errors for a particular topology rules, find errors in visible extent and find exception.

2. From the geodatabase topology, once you set up all the rules, the software will shows all the errors in the colour of red  Use Fix Topology Error in Error Inspector to fix the errors.  Click on the map or right click one of the available fixes. The fixes listed depends on the typr of error. Validate the topology again to ensure the edit was correct. It is to check the features to identify any violation of the rules.

1. Project activites, the design, implementation, and administration of a project are complicated since they don't entail a lot of simple, repetitive tasks, but rather demand specialised knowledge and abilities. An introduction to project management, including its goals, essential elements, and the integration of GIS projects into wider organisational and even societal cultures, can be found in this chapter.

2. Resource requirement is the project's tasks necessitate the use of resources. In other words, whatever it takes to complete a project activity can be included in these resources.

4. Initiation phase findings are summarised in a document known as a project proposal, also known as a project overview statement or project description form, which is submitted to the organization's top management for approval. A template can be used to create a Project Business Case (PBC). Templates are popular because they are simple to produce, change, read, and standardise, making it possible for all projects within a company to be presented to management in a uniform format for consideration. As an alternative, a form called a Proposed Solution (PS) might be employed. The PBC form offers information that top management can use to better comprehend the project's rationale. The content of the form should be prepared in clear and unambiguous commercial terms. There is a clearer description of possible remedies in the PS form, though. If multiple approaches to solving an issue are suggested, the benefits and drawbacks of each strategy, as well as the factors that led to the final decision, must be clearly stated.

1. This software application, often known as a database management system (DBMS), is responsible for defining, manipulating, retrieving and managing data contained within databases. In order to identify the possible values that can be put in a column, data types are categorised. GIS DBMS data types includes Long Integer, Integer, Single, Double, Text, Date/Time, OLE Object, and Number.

2. A Database Management System (DBMS) is a set of computer programs that controls the creation, maintenance, and storage of data in a database. A database is a collection of tables; GIS incorporates much of the functionality of DBMS. Businesses and government agencies rely on extensive databases for their billing, payroll, inventory, and marketing operations.
