When I asked: "How do we convert more than 12,000 location items - by hand?" we had almost completed the process as part of our move to Microsoft's up-coming SQL Server 2008. The question was, in fact, rhetorical. Nevertheless, we received a lot of advice and suggestions from Reg Dev readers. This, for example, from …
Yea, me too.
Apart from geospatial types (which I'm going to be using for a GPS based application), we also have hierarchies (via hierarchyid), alternatives to storing image blobs in the database (FILESTREAM) and a way of passing arrays into stored procedures (table based parameters). These are the 4 main new features of the DB engine and all 4 of them are going to make my life a lot simpler.
Google Pleasby, find a book impression about Forest Scenery, google some other places near it, notice there is another edition of the same book where Pleasby is now called Pleasley. Find Pleasley on maps. There is a wood to the NE of it, just north of Pleasley Vale. And although it says Derbyshire on Google maps, the Notts/Derbys border runs right through it.
T'internet's marvellous, isn't it?
ESPG 4326 = WSG84
The 4326 is the WSG84 datum describing the curvature of the earth. It's the most commonly used datum when handling coordinates
That 4326 is...
...the ID of the coordinate system used to give the number pairs meaning. This particular ID is published by the European Petroleum Survey Group (ESPG) and is a de-facto standard in the GIS world. 4326 means that the numbers are in Latitude / Longitude, with Greenwich at 0 Lon, and with the WGS84 ellipsoid (a slightly squished sphere) used to model the surface of the earth in order to figure out where those coordinates end up.
Well, now, that should be cleared up.
Excellent Andrew, thank you! That's another one accounted for.....
I think is on the Clayhithe Road, between Horningsea and Waterbeach.
AC is very kind but these four
Streatley Hill, Berkshire
Causey Pike Gill, Cumberland
are examples of ones for which we DO know the location:
However, as I say, the thought is much appreciated,
I guess you're a a Microsoft shop, but I wonder if PostgreSQL with the PostGIS spatial data add-on (http://postgis.refractions.net/) could have met your requirements?
If so, you have a valuable backup strategy if MS suddenly drop spatial data to get it out the door on time. Possibly worth some research while you wait for MS to get to the party?
Why are you attempting to store image Binary Objects INSIDE the DB?
Sheesh. Kids nowadays.
Coordinate mapping is already happening in databases. Now. Today. In really bog-standard RDM systems.
Is this really something to get interested in? Is software engineering so bereft of ideas that this actually seems cool?
