DEMs stored as band interleaved by line (.bil) files Note that the output raster dataset will not have a projection associated with it – in order to assign one, use the Define Projection tool (ArcToolbox > Data Management Tools > Projections and Transformations > Define Projection). flt into another format, you can use the Float to Raster tool (ArcToolbox > Conversion Tools > To Raster > Float to Raster) to convert it, simply by specifying the input dataset and the output path and filename. However, should you need to convert your. flt files like any other raster datasets, allowing them to be added directly to a map document via the Add Data button, or used in Spatial Analyst operations, without the need for conversion. It can now be used in raster-based spatial analysis, or as an elevation surface in ArcScene.ĭEMs stored as floating-point value (.flt) files The resulting raster dataset will automatically be added to your map document.
Click OK to begin the conversion process. ArcMap will set a cell size for the output raster based on the extent of the input dataset, which can be adjusted in the Cellsize field – depending on your desired cell size, you may wish to adjust the Cell assignment type and Priority field settings accordingly. Indicate the desired location and filename for your output dataset in the Output Raster Dataset field, noting the specifications for particular raster file formats in the Tool Help pane. In the Value field dropdown, select Shape.Z. In the Input Features dropdown menu, select the shapefile of elevation points. In ArcToolbox, expand Conversion Tools, then To Raster, and double-click on Point to Raster.This indicates that elevation or height values are included in the spatial reference information for each entity in the dataset.Ĭlick OK or Cancel to return to the map document. You should see the line “Coordinates have Z values: Yes” in the Data Source section of the window. Open up the Layer Properties window and click on the Source tab. Add your DEM point dataset to your map document.
