Geomaticians create digital maps and 3d geological models for resource exploration and environmental and engineering applications; they collect, organize and analyze the geographic data in digital form. Select a methodology: to collect data in order to help solve problems. Analyze and interpret the information: can use maps or computer graphics to come up with a solution. Hypothesis: a theoretical explanation (may use multiple hypothesis) Theory: a hypothesis that passes through repeated testing.
