MANAJEMEN DATA SPASIAL

GEOREFERENSI DALAM ARCGIS 1. MENGGUNAKAN DATA SPASIAL LAIN YANG BERGEOREFERENSI 1.Add the layers residing inmap coordinates and theraster dataset you want togeoreference. 2.In the table of contents, right-click a target layer (thereferenced dataset) and clickZoom to Layer. 3.From the Georeferencingtoolbar, click the Layerdropdown arrow and clickthe raster layer you want togeoreference. 4.Click Georeferencing andclick Fit To Display.This will display the rasterdataset in the same area asthe target layers. You canalso use the Shift and Rotatetools to move the rasterdataset as needed. To see allthe datasets, you may haveto adjust their order in thetable of contents. 5.Click the Control Points toolto add control points. 6.To add a link, click the mousepointer on a known locationon the raster dataset, then ona known location on the datain map coordinates (thereferenced data).

ou may find it useful to use aMagnification window to addin your links.

toevaluate the transformation.You can examine the residualerror for each link and theRMS error. If you’re satisfiedwith the registration, you canstop entering links. 9.Click Georeferencing andclick Update Georeferencingto save the transformationinformation with the rasterdataset.This creates a new file withthe same name as the rasterdataset, but with an .aux fileextension. It also creates aworld file for .tif and .img files.

PROYEKSI DATA UNTUK DISPLAY DI ARCMAP:

A data layer's coordinate system information can be found by viewing its spatial metadata. When data sets have the same coordinate system they are correctly positioned with respect to each other in the data frame. If a data set is added to an ArcMap display that has a different coordinate system from those layers that have already been added to the data frame, ArcMap automatically changes its display so that it matches the existing layers. This change is only temporary and only exists within a particular data frame. The underlying coordinate system information DOES NOT change.

Projecting and Defining the Coordinate System or Spatial Reference:

Though one of the principal features of ArcGIS Desktop is the ability to change a dataset, feature class, or raster file's projection "on the fly" for display and analysis purposes, if the user acquires data sets

[email protected] – Diklat BAKOSURTANAL

with different coordinate systems or projections, the user may wish to change them so that they all match. A user can project data to a new data set using ArcToolbox™ Project for features and Project Raster for raster files, or the user can define or change the projection and coordinate system of a data set using Define Projection.

To project or define a projection or project data, the user must click the plus sign next to Data Management Tools, followed by a click on the plus sign next to Projections and Transformations.

Project and Project Raster reproject input data and saves it as a new data set. Project allows the user to define or project feature classes and geodatabases. Project Raster allows the user to define or project coverages, grids, or TINs. The Define Projection tool applys coordinate system information to data sets and feature classes.

For example, if the user wishes to project a feature class the Project tool (shapefiles, geodatabases) should be opened by double-clicking on the option in ArcToolbox. Once the Project dialog box opens, the user must select the data set to define. This can be done by clicking the folder icon and navigating to the shapefile or geodatabase of interest.

Once the data set name has been added to the dialog, the Output Coordinate System must be selected. To select a coordinate system click on the Spatial Reference Properties button highlighted by the red circle in the graphic above. The Spatial Reference Properties dialog box appears.

Within this dialog box, the user can select a predefined coordinate system, import a coordinate system from another data set, or create a new coordinate system. Once a coordinate system has been

selected, the Spatial Reference Properties dialog box will be updated with the details of the selected coordinate system.

When the user clicks OK, the Output Coordinate System name appears in the Project dialog box.

Clicking OK produces a new data set with a different coordinate system. The new data set is automatically added to the list of layers. Though the new data set is a different coordinate system than the other layers it has been reprojected on the fly to match the other layers on screen.

UPLOAD DATA MEMBUAT GEODATABASE BARU 1.Click the ArcCatalog buttonin the ArcMap Standardtoolbar to open ArcCatalog. 2.Click a folder or create a newfolder to create the geodata-base in. 3.Right-click the folder, point toNew, then click PersonalGeodatabase. 4.The folder name is already highlighted so you canchange the name to some-thing more appropriate.

MEMBUAT FEATURE CLASS 1.Right-click the geodatabasewhere you want to create thefeature class. Point to New,then click Feature Class. 2.Enter a name for the feature. 3.Choose the type of featureclass to create. 4.Click Next. 5.Specify the database storageconfiguration. ChoosingDefault is often sufficient. 6.Click Next. 7.Click Shape under FieldName. 8.Under Field Properties,choose the Geometry Type byclicking in the space beside itand clicking the option youwant from the dropdownmenu.If you do not choose aGeometry Type, the default isPolygon. 9.Click Finish.To add this layer to ArcMap,you can click and drag it aspreviously described in‘Adding a layer fromArcCatalog’.
