GCP is a point that is used to give coordinates and geometric corrections in satellite images or aerial photographs. We carried out this survey using GPS at points that can be identified both on an image and on the field, whether it’s from existing objects such as the corner of the basketball court, the center of the basketball court, or by pre-made mark.
Topographic survey is a method to collect coordinates of natural and man-made features and their elevations on a large scale in an area. This survey can produce a base map that will be used as a reference or analysis material in project planning. With our competent people in spatial technology, we have helped clients in various projects such as infrastructure development, land clearing, making an RBI Map (Peta Rupa Bumi Indonesia), and so on.
Toponym survey is a survey consists of taking photo of objects, toponym data of a place, and coordinate data using mobile devices such as Handheld GPS and apps such as Survey123 or CarryMap. The result of this survey is a database containing informations of various objects in an area for further analysis. This survey needed specially to obtain attribute information for GIS Map of a city.
Well survey is an activity to determine the relationship between the transformation parameters of the old coordinates and new coordinates, which refers to the national coordinates system. This survey is conducted using Geodetic GPS dual frequency to confirm the fixed points of exploration or exploitation wells (especially in oil and gas industry) have been tied to a reference point from Geospatial Information Agency (BIG) or to an existing point that user already had in the field.
