Use a file browser to explore the folder C:\FMEData2017\Data\Orthophotos. This is not something you've had to do before, but you know there must be a transformer to do so!.You need to overlay the road features on to the raster data.The transformer to use will differ depending on what technique you decide to use. The most obvious visual difference would be colour, but size might also work.You need to differentiate road types in some way.Again, you will need to cut the data back to the required area.The project requires only four road types, so not all source data layers are required.You need to read an AutoCAD DWG file of roads.The area of the project is not the entire city (just two neighborhoods) so you will have to find a way to avoid reading excess files in the final solution.There are a lot of files so while prototyping the workspace you may wish to cut back on the amount of data being used to test the solution.You need to read a set of GeoTIFF files.Let's first consider the steps we know are needed for the project. The source data consists of a lot of files and layers, and the FME workspace will include a number of operations that might be carried out by different transformers but luckily you've just learned all about proper methodology in FME and are looking forward to applying that knowledge on this project. Each type of road feature should be depicted differently in some way, so as to make their type visually recognizable.Īs the resident spatial data expert, you've been asked to create this dataset. The data should cover the neighborhoods of Downtown and the West End, and the road features should only be of the types Arterial, Residential, Secondary, and Other. Orthophoto images (GeoTIFF), Roads (AutoCAD DWG)Ĭreate a workspace to overlay road features onto raster imagesĬ:\FMEData2017\Workspaces\DesktopBasic\BestPractice-Ex2-Complete.fmwĪ mapping project in the city requires a dataset of roads laid down on a raster background.
