You can find an SSRS tutorial over at Scribd.
This is based on notes I collected over time and compiled into a short ebook to use for a training class I gave. It’s designed to be “print friendly”… so you can print it out and follow along. It includes some simple step by step geospatial (map layer) examples.
It’s my humble contribution back to the SSRS community that help me learn this. Have fun and feel free to send me feedback.
