comment Road traffic database sample?
I couldn't say for the whole world, but I would start with looking at Open Street Map (OSM). Inrix (inrix.com) is a private company that provides traffic information. OpenTraffic (opentraffic.io) is an initiative to provide open real-time traffic information, similar to Google's traffic. I would start there.

comment ArcGIS Online attribute hyperlink is not reading the space in URL, how to fix?
Replacing the strings in the gdb column is not a difficult task, it can be performed in the Field Calculator.

Neither of these are options, as the question was for free private services

comment How do I use EllipseMarker in QGIS 1.8?
Is there a reason why you are using v1.8 and not v2.8?

comment Is there a way to add x , y, z coordinate to the attribute table of polygon in ArcGIS 10.1?
Then you need to export the nodes as points, then calculate the x,y,z. If you have a unique ID for each polygon, that ID will come over when you export/convert the nodes to points. With that, you can relate the nodes x,y,z back to the polygons. Really there isn't any other way.

Looks like you need dissolve the neighbouring polygons first

I am not sure I am understanding your issue. According to your comment, you need the x,y,z centroid of the polygon. The process described above will provide you what you need. I would suggest that you edit your post to clarify your requirements, as well as provide a screen shot of our issue, so that others can visualize what you are asking.

comment Drawing 100x100 meter with 5 rows and columns grid centered on one point for multiple points?
Do you want a grid around the buffer, or a grid inside the buffer?

Would a buffer work? There is an option to make it flat not round, which would give a squared cell look.

comment Is there a better way to convert Raster to Point data? Don't need one point for every cell
what about a raster calculation to remove cells you are not interested in. Alternatively, you could convert your rasters to polygons, and use the polygons as a means to select/delete points (ie: no data, or other land use).

comment Computing population exposure
Good point Joseph. I haven't used ArcGIS in some time, so I am unsure if that will be a requirement. There may be some work post conversion.

comment Shapefile created in QGIS will not display properly in ArcGIS
What issue are you seeing in ArcGIS. You need to provide more information, so the community knows what to look for.

comment Is it possible to use AcuGIS with QGIS?
As a side note, this company is terrible. Horrible customer service, very unprofessional. They are still billing me 9 months after I closed my account. Wanted everyone to know about them before you get yourself into a bad situation.

comment How to Generate Points on Corner of Polygon Only
What GIS application are you using? In QGIS you could look at using Vector - Simplify Geometries. ArcGIS will have a similar tool. It will remove vertices from a shapefile from within a tolerance, which is based on a distance.

comment How to Generate Points on Corner of Polygon Only
Why do you have so many vertices for rectangles? If you were to remove all the non essential vertices (ie: the ones between corners) you would be able to get what you want. Having all those vertices is not a good thing to have in your polygons.

You could add a new column to your polygon and do a reclassification based on your needs

Can you comment more on what you mean, or what you would like to have as an outcome.
