Spatial

I need to import the spatial data in shape file into MySQL tables. I am able to import into PostGreSQL. Any pointers for MySQL. I need the data in MySQL table. try this whit FWtool instaled ogr2ogr -f MySQL MySQL:database_name,host=localhost,user=root,password=1234 C:\route_path\line.shp -nln datatable_name -update -overwrite -lco engine=MYISAM try install for better result in any proces Osgeo4w http://trac.osgeo.org/osgeo4w/ I have just used the ogr2ogr command line tool to import the shape file into the mysql database. Make sure that the database server allows external connections. If doesn

Long long struggles with this... Basically I have a model-first EF5 object with a DbGeography property. I would like to apply a JsonConverter that let's it roundtrip as simple latitude/longitude values. I'm using WebAPI. Looking for JSON output and input like so: { "location": { "geopoint": { "latitude":40.770712, "longitude":-73.962011 } } } Here is my class definition and JsonConverter: [MetadataType(typeof(QueryLocationMetadata))] partial class Location { } public class QueryLocationMetadata { [JsonConverter(typeof(DbGeographyConverter))] public virtual DbGeography GeoPoint { get; set; } }

We have a list of x,y pairs. Every pair represents a point on a 2D space. I want to find the closest point from this list, to a specific point xq,yq. What is the best performance-critical algorithm for this problem? Lisp of points is not going to change; which means I do not need to perform insertion and deletion. I want just to find the nearest neighbor of a target xq,yq point in this set. Edit 1: Thanks to all! As Stephan202 has guessed correctly, I want to do this repeatedly; like a function. An the list is not necessarily sorted (In fact I do not understand how can it be sorted? Like a

I'm having some fun trying to pick a decent SQL Server 2008 spatial index setup for a data set I am dealing with. The dataset is polygons, representing contours over the whole globe. There are 106,000 rows in the table, the polygons are stored in a geometry field. The issue I have is that many of the polygons cover a large portion of the globe. This seems to make it very hard to get a spatial index that will eliminate many rows in the primary filter. For example, look at the following query: SELECT "ID","CODE","geom".STAsBinary() as "geom" FROM "dbo"."ContA" WHERE "geom".Filter( geometry:

I have (what I think) is a simple Sql Server spatial query: Grab all the USA States that exist inside some 4 sided polygon (ie. the viewport/bounding box of a web page's google/bing map) SELECT CAST(2 AS TINYINT) AS LocationType, a.Name AS FullName, StateId, a.Name, Boundary.STAsText() AS Boundary, CentrePoint.STAsText() AS CentrePoint FROM [dbo].[States] a WHERE @BoundingBox.STIntersects(a.Boundary) = 1 It takes 6 seconds to run :( Here's the execution plan.... Removed And the stats on the Filter operation... Removed Now, I'm just not sure how to debug this .. to figure out what I need to
