**3. Methodology**

#### **3.1 Main phases**

Given that GIS and database are meant to respond to a specific need, it is imperative that, objectives of the task ahead should be clearly outlined to suit expectations most accurately. In an early stage of mining projects wherein stream sediment sampling and large scale mapping is carried out, there are three main phases which are Planning, Field work, Assessment and data validation as seen in **Figure 3**. Each phase has special tools, expertise and logistics. This chapter is design going through those phases of the work laying emphasis on the Meiganga toposheet.

#### **3.2 Technical settings**

Every project has its specifications when it comes to choosing the types of tools and software in order to achieve the work. In this case the equipment used include: the GIS and database equipment which consist of a laptop, notebooks, and GPS. GIS software like ArcGIS 10.5 can be chosen to build maps and make geospatial analysis. Basecamp is also used with the aim to send maps and planned points inside the GPS.

The same software can be used to extract prospectors' tracking and recorded points, the coordinate system used in the building of maps can be WGS 1984, with UTM as units. As regarding database, Microsoft Access can be used to build tables and record related field information. The software is also used to record all the codes employed during the work i.e. rock codes, initials of the geologists, abbreviations of the targeted
