Aerial photogrammetry is one of the Alternative technologies for more detailed data, real time, fast and cheaper. Nowadays, many photogrammetric mapping methods have used UAV / unmanned drones or drones to retrieve and record data from an object in the earth. The application of drones in the field of geospatial science today is in great demand because of its relatively easy operation and relatively affordable cost compared to satellite systems especially high - resolution satellite imagery.  This research aims to determine the stage or overview of data retrieval process with DJI Phantom 4 (multi - rotor quad - copter drone) with processing using third party software. This research also produces 2 - dimensional high resolution image data on the research area. Utilization of third party software (Agisoft PhotoScan) making it easier to acquire and process aerial photogrammetric data. The results of aerial photogrammetric recording with a flying altitude of 70 meters obtained high resolution images with a spatial resolution of 2 inches / pixels.

Lubis MZ, Anurogo W, Hanafi A, Kausarian H, Taki HM, Antoni S. 2018. Distribution of benthic habitat using Landsat-7Imagery in shallow waters of Sekupang, Batam Island, Indonesia. Biodiversitas 19: 1117-1122. Shallow sea waters are one region thathas high dynamics and an important role both economically and ecologically. Batam Island one of the islands in Indonesia is rich in theocean in Riau Islands Province, Indonesia, and surrounded by small islands.We conducted classification and correction of water columnusing Lyzenga formula, to see benthic habitat in Sekupang waters, Batam Island, Indonesia. This research uses remote sensing method withLandsat-7 image data, on data recording that is dated December 16, 2016. The purpose of this study is to obtain information on thedistribution and extent of sand, dark sea, and coral reefs on Batam Island shallow waters of Sekupang. By using the formula of Lyzengaalgorithm, the value of ki/kj is 0.404, by looking at the color change corresponding to the channel. Research result of classification in theshallow coastal waters of the island of Batam in Sekupang with the area is sand with 27.64 % (3.443 ha), cloudy sea with an area of 30.94%(3.854 ha), and coral reefs with an area of 41.43% (5.161 ha).

3D modelling of buildings in Google Earth in Batam city, Indonesia is very important for knowledge about facility, infrastructure, and others.Three-dimensional (3D) visualisations are an interesting method for representing model outcomes. This research In Tunjuk island with coordinate, at Latitude: 0.984123°, and Longitude: 104.225606°, with technical terms, there are two alternative routes for implementation, and they both share the same starting stage. In (Figure 5) visible visual measurements of the master plan that has been made has a length 141.99 metre and width 54.25 metre with location at Latitude 0.984593° and Longitude 104.228073°. In (Figure 5) visible visual measurements of the master plan that has been made has a length 92.96 metre and width 135.46  metre with location at Latitude 0.984593° and Longitude 104.228073°. This paper presented a rapid visualisation tool for supporting the joint decision making in evaluation of design/renewal proposals in Batam City, Tunjuk Island, Indonesia. 3D building using Google Earth (GE) and combaining Geographic Information System (GIS) system be done officially on a sampling or auditing basis by a professional body or by researchers, or it could be done by volunteers and user groups.

APPLICATIONS OF REMOTE SENSING TECHNOLOGY IN COASTALAND OCEAN Many remote sensing applications are devoted to the coastal and ocean sector. Representative case studies are presented in the special issue "Advances in Remote Sensing of coastal and ocean". Remote sensing techniques represent a powerful tool for landslide investigation: applications are traditionally sea surface temperature, marine habitat into three main classes, although this subdivision has some limitations and borders are sometimes fuzzy in coastal and ocean. Remote sensing combined with geographic information system (GIS) can be used as a technology tool to obtain information about the object quickly and accurately, including objects in coastal and ocean areas. Remote sensing data on coastal and marine areas specifically for the region in Indonesia have been widely practiced. The use of remote sensing data and GIS in coastal and marine areas can be used to determine sea surface temperature, determination of fish catchment area, and coastline morphological changes by adding other influential parameters. It can also be used to monitor a regional change by using multi-temporal recording data such as disaster monitoring, monitoring of land cover changes in coastal areas etc. Remote sensing data essentially can be used as an alternative technology in obtaining information at a cheaper cost when compared with the conventional way.
