Activity Measurements are typically performed to determine the boundary of an area. Results of the measurement boundary is generally in the form of point coordinates X, Y and Z. The point coordinates are then processed into a map to determine the position on the field. On this learning activity you will map the coordinates of digital teodolite measurement results into a picture of a map by using the program ArcGIS 10.1,
Follow with a good and conscientious step input, store and retrieve data because the result will greatly influence the success in displaying the object map. Knowledge of geographic information system is needed to support the technique of making maps, therefore, before discussing technical making of the map will be presented in advance the concept of a geographic information system to help you understand more deeply the concept mapping.
Geographic Information System can be utilized to facilitate in obtaining the data that has been processed and stored as an attribute of a location or object. Data were processed in GIS basically consists of spatial data and attribute data in digital form, These systems relate spatial data (geographical location) with non-spatial data, so users can create a map and analyze the information in different ways.
GIS is a powerful tool to handle spatial data, wherein the data in GIS is maintained in digital form so that the data is more dense than in the form of a printed map, table, or in other conventional forms which will ultimately speed up the work and alleviate the costs involved. Some of the reasons underlying the use of GIS by Anon is:
1. The use of GIS spatial data and attribute terintergarsi
2. GIS can be split between the form of presentations and databases
3. GIS has the ability to decipher the elements that exist on the surface of the earth into several layers or spatial data coverage
4. GIS has a very good ability to visualize spatial data following attributes
5. All operations can be done in an interactive GIS
6. SIG easily generate thematic maps -peta
7. GIS greatly assist the work in close relation with
8. The field of spatial and geoinformatika.
SIG position with all its advantages, the longer growing increase and bervarian. Utilization of GIS widespread covering various disciplines, such as health sciences, economics, environmental sciences, agricultural sciences, military and others.
Application of GIS in digital mapping
Digital mapping is a process of map-making work in a digital format that can be saved and printed according to the manufacturer desires either in number or scale maps produced. Digital mapping is done by using the Geographical Information System. GIS is a system of management of geographically referenced data that can be used for data input, data manipulation, so as to obtain new data or information.
GIS can be used in mapping forest boundaries, forest governance, and monitoring of forest resources. GIS can generate a map from multiple sources such as field measurements, interpretation of remote sensing imagery, and aerial photographs. GIS can generate a map briefly, automatically, and repetitive quickly. Here are a few examples of GIS applications:
1. Management Facility: Map of large-scale network analysis, usually used to refineries town facilities. Examples of applications are the placement of underground pipes and cables, planning of maintenance facilities, telecommunication network services
2. refineries Natural Resources and Environment: For the purposes of this commonly used satellite imagery, Landsat images digabungankan with aerial photographs, with the overlay technique. Example applications are feasibility studies for peranian plants, forest management and environmental impact assessment
3. Transport Sector: For this function to use medium and large-scale maps and spatial analysis, especially for management planning transit routes, pengirimsn technicians, analytical services, marketing management and so on.
