First, the classic technique is the raster clip tool in Data Management of ArcToolbox. This has been around for awhile.And second, the ArcGIS 10 Image Analysis Toolbar can clip rasters as well. The main advantage of the Image Analysis Toolbar is that you can visualize the end-result before you export it.Sounds neat? Let’s take a look at both techniques to clip rasters in ArcMap. Raster Clipping Techniques in ArcGISAs shown in the image below, we will clip a “Shaded Relief” raster to the state of Wyoming which is a polygon boundary. Wyoming in CenterHere are step-by-step instructions how to clip rasters using two techniques in ArcGIS.Of course, if you are looking for more time-saving tools in ArcGIS, check out our section for more.
Creating polygons from polylines Start ArcMap. On the main menu, click Customize Toolbars Production Editing. On the menu bar, click Customize Toolbars Production Feature Builder. Click the Feature Builder button on the Production Feature Builder toolbar. Verify that the feature builder. Created polylines can be stored either in a new shapefile or in the geodatabase feature class. If no polygons are currently selected, all polygons in the layer will be processed. Source layer may include single part, multipart or complex polygons. The output polyline attribute table will consist of the same fields as one of the input polygons, except ID field that can be optionally added.
1 ArcToolbox Clip Raster ToolIn the first example, we use the Raster Clip tool in the Data Management toolbox.Here are the steps to follow to clip raster using this method. If you want to follow along, you will need a raster image and a polygon boundary.In this example, we are using the. Alternatively, you can use GIS data in our. Step 1 Select Clip Tool in ArcToolboxIn ArcToolbox ( Data Management Raster Raster Processing Clip ), double-click the clip tool.Step 2 Fill in fieldsINPUT RASTER (REQUIRED): This is the raster you want to clip. We want to clip the “Shaded Relief” raster.
OUTPUT EXTENT (OPTIONAL): This is the polygon boundary you want to clip to. You can select specific records in the polygon dataset and it will only clip this boundary. In our case, we would select the polygon of Wyoming before dragging and dropping it in the field. If you have coordinates instead of a polygon extent, type the maximum and minimum X and Y values.USE INPUT FEATURE FOR CLIPPING GEOMETRY (OPTIONAL): This checkbox clip rasters to a polygon boundary. We want to clip to the state of Wyoming so insert a checkmark in the checkbox.OUTPUT RASTER DATASET: This is the name of the output (clipped raster). Add an extension for the output such as.TIF,.IMG, or.JPG.NODATA VALUE (OPTIONAL): This means all the pixels with the specified value will be set to NoData in the output raster dataset.
You can change this value in this field.Step 3 Run toolRun the “clip” tool by clicking OK. Finally, the tool will clip the raster to the polygon extent. Clipped Raster of Wyoming Shaded Relief 2 Clip Raster with the Image Analysis ToolbarFor the Image Analysis Toolbar method, the main advantage is that you can visualize the end-result before you export it.Essentially, you create a temporary raster. If you like the temporary result, you can save it to memory.Here are the steps to clip rasters using the Image Analysis toolbar in ArcGIS: Step 1 Enable Image Analysis ToolbarEnable the Image Analysis Toolbar ( Windows Image Analysis ). After, this will display the image analysis window pane in ArcMap. Image Analysis Toolbar Step 2 Select Raster to ClipIn the image analysis toolbar, select the raster that you want to clip. Make sure you select the checkbox and highlight the raster.
If you don’t highlight the raster in the image analysis toolbar, the clip button will be greyed out. Select Raster in the Image Analysis Toolbar Step 3 Select Polygon Boundary to Clip ToSelect the record of the polygon that you want to clip the raster to. Attribute table of the United States polygon boundaries Step 4 Click Clip IconClick the “clip” button in the image analysis toolbar. This will create a temporary raster. You can view the temporary clipped raster for an idea of how it will look when exported. All you have to do now is save this clipped raster. Image Analysis Toolbar Clip Button Step 5 Export RasterIn the Image Analysis Toolbar, highlight the new clipped raster the tool creates.
Save the new clipped image by clicking the export button. Export raster buttonChoose the location and name of the file that you want to save. You can also change the cell size and the format of the clipped raster. Finally, click save to export the raster.
Are the pixels actually shifting? For example, the input raster will have different values compared to the output raster in different locations of the raster? Or is the shift associated with how/where the shapefile is clipping the raster?If you were to resample your raster to a finer resolution and then clip the raster, what would be the result? Would there still be a shift?Is the shapefile used to clip the input raster in the same coordinate system?Sorry, but I’m a bit confused with the question.
.In the Create Features pane, polygon construction tools create single-part and multipart polygon features. Segment construction tools appear on the construction toolbar when a tool allows you to sketch connected straight lines, arcs, and curves.Vertices for z-enabled features are assigned z-values based on the current elevation input mode setting. To learn more, see.The following sections include steps for polygon and freehand polygon features. For steps to create circular or square polygon features see the following topics:.PolygonTo create a polygon feature, clickPolygon and click the map, or right-click and specify a coordinate location for the first vertex. Right-click and use the context menu to specify coordinates or apply constraints, and use tools on the construction toolbar to create straight and curved segments.
