To make a good geological map, a geologist must have good skill in geological mapping and know well about how to read geological map. Basic step of geological mapping consists of observation and measurement in field, taking samples, and analyze samples in laboratory. Geological mapping is a multidisciplinary method that combines all geological disciplines such as petrology, structure geology, geomorphology, paleontology, stratigraphy, sedimentology, etc. Geological mapping consists of two kind based on selection trajectory, they are:

Basic steps of geological mapping consist of observation and measurement in the field, taking samples, and analyzing samples in a laboratory. Geological mapping is a multidisciplinary method that combines petrology, structural geology, geomorphology, paleontology, [[stratigraphy]], sedimentology, etc. Geological mapping consists of two kind based on selection trajectory:
* Systematic mapping is done by mapping technically only, without considering geomorphology, distribution of geomorphology, or geological structure pattern. While smart mapping is done by considering the results of
satellite image or topographical maps analysis, so it would be more efficient in geological mapping according to the desired scale. In this paper we are more focus on the method of smart mapping because this method is most often used by geologists.

The key points of smart mapping are:
* Smart mapper will start by looking at aerial photos to determine where the available outcrop is and then make 2-3 traverses across [[strike]] to ground the photo interpretation
The key points of smart mapping are :
* Searching patterns will focus in on key areas of interest e.g. [[shear]] zones
* Smart mapper will start by looking at aerial photos to determine where the available outcrop is and then make 2-3 traverses across strike to groundtruth the photo interpretation
* Searching patterns will focus in on key areas of interest e.g. shear zones
* Less time is spent in areas where the rocks are uniform and a lower density of observations will serve.

* Most useful observations are the predictable geometrical relationships between bedding, cleavage, lineaments and [[fold]]s as well as movement indicators for brittle and ductile shear zones
