Create surface models from a Digital Elevation Model (DEM). In this example, FME was used to transform a DEM to a TIN, and then to drape a JPEG on top in order to create a 3D textured model.
FME provides many ways to manipulate rasters. Some examples include to clip a raster to boundaries, tile a raster into more manageable pieces, or merge tiles into a seamless raster mosaic.
FME lets you perform calculations based on the value of one or more cells, detect changes between two inputs, and modify pixel values based on an algorithm.
Use FME to classify a raster by creating polygons based on analysis. In this example, areas on the southern slope of this terrain possessing a slope value between 10 to 25 degrees, are identified a suitable for growing a particular crop.
FME's MapnikRasterizer transformer was used to create this map from a series of shapefiles containing information about elevation, roads, hydrography, and railways. The same technique can be applied to any vector format. FME can also be used to turn point clouds into raster.
FME supports over 5,000 coordinate systems. Here, an ortho map for Vancouver in UTM83 projection was reprojected into Spherical Mercator for raster tiling to make web map tiles compatible with Google Maps, Leaflet, ArcGIS, OpenStreetMap, and Bing Maps.
Convert rasters into dozens of other raster formats. Or integrate rasters with BIM, CAD, and GIS – for example adding topography to CAD or BIM models. In this example, a DEM and ortho are turned into a 3D PDF model.
Integrate Raster with GIS & CAD
Your raster data is more valuable when combined with data from other systems. FME allows you to convert your raster files in formats like GeoTIFF, ECW, PNG, JPEG and more for use with a wide variety of applications across BIM, CAD, and GIS.
FME supports hundreds of applications and formats across data types like: GIS (Esri ArcGIS, MapInfo, KML), Spreadsheets (Excel, CSV), LiDAR (LAS, Autodesk ReCap, E57), BIM (IFC, Revit, SketchUp), CAD (AutoCAD, MicroStation, Civil 3D) and many more including Minecraft, JSON, and PDF.
Popular FME Transformers for Raster
FME Desktop contains hundreds of general purpose transformers, plus more than 50 transformers specifically designed for raster processing tasks. These include:
Extracts the band and palette values from a raster at the location of each input point.
Top Raster Productivity Tool
FME Desktop is a whole new way to transform raster data. Instead of coding a stopgap solution or living with the status quo, FME lets you work with your data in a repeatable way using a drag-and-drop interface.
Simply specify your inputs and add any number of FME’s 450+ transformers. Link transformers to manipulate your raster data in any number of ways – mosaic, convert, tile, clip, and so much more. The next time, just press the “Run” button and you’re done – no coding required.
Because of its ability to represent continuous surfaces, raster data is often used as a component of intense spatial analysis. The large number of different raster formats makes datasets difficult to share, particularly when an application also has different structural requirements. FME offers a solution to ensuring this carefully collected imagery can be distributed for use by all stakeholders in their system of choice.
