+======ThinkGeo Maps Streets Data======
+ThinkGeo Maps Streets Data has 2 versions:
+  * A single SQLite file which is over 160G and includes the full version of the data. In addition to being used for rendering, it can also be used for Routing and other purposes. It can be used in any ThinkGeo UI Controls. It supports both Decimal Degree and Spherical Mercator projections.
+  * A single mbtiles file which is over 50G. It's simplified and optimized for rendering, cannot be used in other purposes like rendering. Attributes data is also stored in the file. It works with ThinkGeo Map Suite 10.5 or newer. It supports Spherical Mercator.
-Maps Streets Data comes from OpenStreetMap and Natural Earth, both of which are open data sets. The data is updated twice a month on ThinkGeo servers keep with the latest data available. Generally speaking, Natural Earth is used at lower zoom levels, and OpenStreetMap is serving for higher zoom levels.
+=====Data Source=====
+ThinkGeo World Streets Data comes from OpenStreetMap and Natural Earth, both of which are open data sets. The data is updated twice a month on ThinkGeo servers. Generally speaking, Natural Earth is used at lower zoom levels, and OpenStreetMap is serving for higher zoom levels.

 Natural Earth was built through a collaboration of many volunteers and is supported by the [[https://en.wikipedia.org/wiki/North_American_Cartographic_Information_Society|North American Cartographic Information Society]](NACIS). It is free for public use in any type of project.</div>
+The data is scheduled to update every other week.
+=====Use the data in ThinkGeo Components=====
+  * The SQLite version can be used in all versions of ThinkGeo UI components. Here is a [[https://github.com/ThinkGeo/WorldStreetsLayerSDKOnWindows-ForWinForms|sample]] using WinForms edition to render the WorldStreets file in Sqlite. The sample data is included. The styling is written in the code, you can always change it but it's not that straightforward.
+  * The mbtiles version works with ThinkGeo UI Components 10.5 or newer. We provided different pre-defined styles and you can easily create your own styling. You can find many predefined styles in [[https://thinkgeo.com/demo-center|ThinkGeo Demo Center]], and check it out [[thinkgeo_stylejson|here]] for how to create your own style.
+=====Sample Screenshots =====
+[[https://wiki.thinkgeo.com/wiki/thinkgeo_cloud_maps_vector_tiles|ThinkGeo Cloud Maps Vector Tiles]] is using the same mbtiles dataset. Check out [[https://maps.thinkgeo.com/|Online Samples]] to find out more.
+The following sample screenshots are using the newer version of the dataset (the one based on mbtiles):
