Academic SPAM or vanity publishing?

I recieved an email from an associate from LAP Lambert Academic Publishing some time back, stating that they found my thesis entitled “Application of GIS in the study of land cover distribution, geomorphometry, terrain and water quality in Asi Khola Subwatershed” in the library at Kathmandu University and wanted to publish it in the form of a book. Furthermore, they would do all this for free! http://utsavmaden.com.np/blog/2010/11/29/academic-spam-or-vanity-publishing/
