Opensourcegisblog.blogspot.com Website Review

A blog devoted to Open Source GIS, Data, An*lysis, Web Publishing, and Image Processing.. After some soul searching, I've decided to stop writing regular blog posts.  It has been my pleasure to help out people interested in doing spatial things...and for free!  The GIS world is large, diverse, friendly, and super smart!  I've enjoyed getting to know what other people are working on around the world and how to approach very complex problems! I've learned a lot in the process, and I hope ideas for posts--which never got done!  I also spent extra time creating a few YouTu*e videos finish the GeoDA tutorial. That was never my intention.  My favorite thing has been to watch QGIS grew into the platform it is today! Lastly, I've decided to re-double my efforts at work in violence prevention and reducing firearm homicides in Baltimore City multiple linked windows can be arranged.  The maps and graphs are interactive, as I'll show in later posts, show selecting features in When I learn a new piece of software, I always go from left to right.   is a nice Project Information option that tells the title, data source and type, project name, number of observations and fields. files.  Remember, are an*lyzing vector data, so points, lines, and polygons. Remember map projections matter, since spatial weights are GeoDa does a great job of offering multiple file types to import. TOOLS MENU: SPATIAL WEIGHTS Spatial weights are used to model spatial relationships. Using GeoDa, on contiguity (where a feature borders another) or distances for distanced based weights. The first option is Select if you have already created weights.  The second option is Create.  Here you will a couple of options to examiner spatial relationships in your data.  Which one you choose should be based on the phenomenon you are studying. Like other types of an*lysis, you will also want to examine how different spatial weights affect your results. CONNECTIVITY HISTOGRAM Another one of GeoDa's cool features is a histogram that shows the
