[OSM-dev] Kosmos and SharpMap

[Igor Brejc]

Hi Francisco,

First the quick answer: no, Kosmos is not using SharpMap. I knew about 
SharpMap for some time, but when I started Kosmos is was just an 
experiment on implementing a simple tile server for OSM. Most of the 
work was on defining and implementing a rule engine and processing OSM 
data with it. The drawing part was (at first) simple, it grew in size 
simply because I added more and more optimizations to draw maps more 
quickly.

SharpMap offers a large set of features valuable for GIS development, 
but Kosmos is still more or less an OSM-oriented tool, so the code is 
OSM data structure-oriented and I'll keep it that way for now.  But what 
I am looking for is .NET libraries for stuff that I really don't want to 
handle myself: image georeferencing (GeoTIFFs for example), 
rectification - I'm not sure if SharpMap does this?

It would be interesting to see the performance of SharpMap-developed 
tool for OSM rendering. Unfortunately I don't have enough time to work 
on OSM - SharpMap integration (maybe your friend does? :) ). I can help 
with the code and any questions.
