I have recently been researching the SQL Server spatial data types and have decided to try and store my long, lat points in a geography field.
I am developing location based service. FYI, the database will expand vastly as time and location are the variables. I am considering GAE for initial deployment. I am open for any of python or java ba
I am using .kml file which points to an overlay image (presumably in UTM projection?). The KML file provides the latitudes and longitudes of the bounding box using the \"LatLonBox\" tag.
I have two tables one called Point and other called Poly i have around 400 polygons in the Poly table and around 200 thousand points in Point table. what i wanted is to find how many points are there
I am t开发者_如何学JAVArying to reproject coordinates from WGS84 to MGA Zone 53, a UTM projection based on the GDA94 datum.I get infinity as my result, which is definitely incorrect.I am using R\'s pr
I have a database which contains a lot of geospatial data ... basically information on 10s of thousands of people, with coordinates for each of them.
I searched on SO and didn\'t really find an answer to this but it seems like a common problem. I have several hundred thousand locations in a database, each having the geocode (lat/long). If it matte
I开发者_运维知识库\'m currently using the GeoTools toolkit to do calculations on marine vessel data, such as calculating the Great Circle distance between two lon/lat points. I have two other requirem
I have read some开发者_StackOverflow社区 articles about using spatial optimized tables. Actually I use stored latitude and longitude as varchar comma-separated (lat;lng).
I have a collection of stores with a geospacial index on the location propery. What I am trying to do is given the user\'s latitude, latitude and a search radius (mi), I want to return the list of st
