Sounds like you're using a Reader followed by a SpatialFilter in FME. IN that workflow we do have to read everything. Suggest instead you use a FeatureReader transformer to read the big feature class. And route your search area into that transformer as the Initiator. Then ask the FeatureReader to do a spatial envelope search. We'll then use the spatial ...

You only need one writer (to the SDE database) but multiple outputs for each feature class. In fact if I specify my Reader feature classes first, when I create my output Writer it asks me if I want to create matching output feature classes, and then all I need to do is link them (and add any transformers between them if desired) I believe there is a way ...

Aggregator will merge geometries based on a specified attribute. If you aren't concerned with any other attributes you can tell it not to keep other attributes, otherwise it can concatenate/sum/average those too.

I don't do a lot of raster work with FME so this might not be entirely correct, but these are the general steps I would use: Use a RasterResampler to change the Cell Sizing of Raster B. You could extract this from Raster A first and feed it into the X/Y spacing. Or, just type it in manually if you know it. Feed the results of the above along with Raster ...

As @Mapperz has indicated, you should use the MeasureRemover. You can specify the name of the measure (if known), or you can remove all measures from the features. If it is in fact Z-values that you need to remove, then the 2DForcer is the transformer to use.

If you have one of the newer versions of FME, there are two online transformers that should do the trick: AzimuthCalculator and 2DDirectionExtender seems like what you're looking for. I just typed the names of the transformers directly into the Workbench screen and they showed up. Combine this with the CoordinateExtractor to find the ending coordinate.

Perhaps a bit late to the party, but for future reference: a simple Spatial Join will do the trick. Define a Merge rule to the concatenate the IDs of multiple features into a single field. Target features: Polyline layer Join features: Polygon layer Join type: One-to-One Field map: right-click a textual ID field of your Polygon layer and set Merge rule ...
