Yes, it is called GeoNames (which you have a geonames tag for) although I cannot guarantee that it has every town in the world: A daily GeoNames database dump can be downloaded in the form of a large worldwide text file (allCountries.zip). Additional country files are available for convenience. You find the files on our download server. Read the ...

Pros: It's a high performance and flexible key/value that can be indexed and queried. I have a complex schemaless web GIS that uses an HStore column for storing the features properties. Cons: Most WMS/WFS tools like Mapserver, Geoserver and similars can't understand and work with HStore columns, so you end up creating hard coded SQL Views (In Geoserver ...

What I did was downloaded the Shapefile for all roads from http://www.naturalearthdata.com/downloads/10m-cultural-vectors/roads/ as per Mapperz's suggestion above.

OpenStreetMap is a crowd-sourced spatial dataset. The free download server (http://download.geofabrik.de/) provides access to daily-updated information. Not sure about traffic volumes though.

An .mxd file specifies one particular way of rendering some data. The .mxd file references your data (by file name, by IP address, by URL, etc, depending on the data). But it does not contain the data. In the ArcGIS world, an .mxd file is often simply called "a map". (The acronym "MXD" stands for "map document".) And yes, you can create as many ...

An mxd file is simply your map. It contains the links to your geodatabases that the current mxd is using, plus any settings that you configured in the mxd (such as symbology, extent, etc). Multiple mxds can all access the same geodatabase without problems. Here is a quick reference - http://wiki.gis.com/wiki/index.php/File_Format_MXD

A shapefile is a simple, nontopological format for storing the geometric location and attribute information of geographic features. Geographic features in a shapefile can be represented by points, lines, or polygons (areas). The workspace containing shapefiles may also contain dBASE tables, which can store additional attributes that can be joined to a ...

here is an intro to geodatabases http://www.acct2day.org/wp-content/uploads/2014/04/Geodatabase-an-Introduction.pdf http://help.arcgis.com/En/Arcgisdesktop/10.0/Help/index.html#//00050000000r000000 and to answer the final question, no you do not make a new one each time you make a new file (if i understand your question correctly)

An easier option than creating python addin would be to create a python script tool that uses various arcpy.GetParameterAsText(0) statements that relate to the Create Database Connection arguments, and then using conditional logic (if, else), is directed to open one of two map documents sourced to either test or production (already saved somewhere on your ...

Non-Arcpy If you don't want to go for arcpy, one solution is to create two separate Mxds. Right Click your original mxd in ArcCatalog and then click "Set Data Source...". In this way you can instantly create a new mxd file which points to your new connection file (e.g. ProductionDatabaseConnectionFile.sde). It takes about 10 seconds. If your original ...
