![]() 793, GEODIST: Stata module to compute geographical distances (last update. Every non-military federal geospatial product of the United States is tied to the NSRS so that they may all overlap and align accurately. 785, GEO2XY: Stata module to convert latitude and longitude to xy using map. Within the United States, this accurate determination of positions forms the scientific basis for all geodetic control, known collectively as the National Spatial Reference System (NSRS). geoNear (query, Profile.class) I am executing the query. geonear- must trade off the reduction in the number of computed distances against. What it means is that near can be used in find () queries or in the match aggregation stage, but geoNear cannot. GeoDist: Constrained distance calculation and associated geotools. Both return documents in order of nearest to farthest from the given point. ![]() And, probably most well-known, by using signals generated by GPS satellites that are located approximately 20,000 kilometers above the Earth, geodesists are able to accurately determine the positions of points to a few centimeters in just a matter of minutes. I have the following code: Query criteria new Query (Criteria.where ('locationTime').gte ( 'date-time')) criteria.fields ().exclude ('friends') NearQuery query NearQuery.near (point).maxDistance (maxDistance).By bouncing signals from satellites located hundreds of kilometers above the ocean, geodesists are able to track the rise of the mean ocean surface to about 1.7 millimeters per year. ![]() With tools that monitor the noise from outside our own galaxy, geodesists are able to measure the distances between two points on Earth to less than a millimeter.With the precision of atomic clocks and lasers, geodesists can measure the pull of gravity so accurately, they could detect changes of one billionth of your body weight. ![]()
