Subcidation 1. Drones will provide new dimensions in large scale mapping and small scale. The width distance is able to reach the places that previously cannot be reached easily by humans. On the other hand, with a fairly sharp photo resolution, small-scale mapping using drones can provide a coverage area and a good level of observation in researching certain objects on the surface. In this case the drone can serve to retrieve visual information from 3D objects in the form of rock outcrops to be modeled in the software. In tropical climates such as Indonesia, rock outcrops can quickly turn weathered and overgrown with vegetation. This causes geological information on rocks cannot be saved. Using information drones can be easily accessed in the future. The first phase of this study was conducted last year by utilizing rock outcrops in the Silokek area, West Sumatra as an experimental project area. The result is still in processing, but while it can be seen the relationship between the type of rock and distribution of intensity and density of the fracture. To model it requires more data that records heterogeneity on rocks from many places so that the database will add a lot and it is expected that the model will be consistent. Retrieval and recording of direct data from the field will still be carried out while starting the second stage of the job, namely building algorithms for software recharge automatically. Subcidation 2. The quality or ranking of coal coatings containing coal methane or CBM can be estimated one of them through proxymatic analysis. In addition, the proximate value can be used as one of the parameters in the equation of calculating coal methane resources (Kim and Douglas, 1973; Kim, 1977; and Mavor et al, 1994) and also used in the correction of the Langmuir Sorption Isotherms equation (Langmuir, 1918) for Calculating the ability of a material stores gas at certain temperatures and pressures and calculates the volume of local CBM gas (gas in-place). But because the proximate analysis and gas content (gas content) must be carried out in core rock samples causing the price to be quite expensive so that not all coal layers and CBM wells have the data and sometimes the analysis is only limited to one time on a thick coal layer. Therefore, a method is needed to estimate the value of proximate analysis and gas content in wells that do not have the data.
