![]() ![]() Has anyone been able to calculate commute distances/ times in stata recently? I know other programs are definitely better at this, but I’m a STATA loyalist so I’d like to do it in stata if possible. The last I can find about most of these commands is about 4-5 years old which isn’t promising. I don’t know if this is user error, or if the commands are not active anymore. I have tried mqtime, georoute, and perm time, but haven’t gotten any of them to work. I would like to also calculate commute distances and times between these coordinates. However this command only calculates straight line distances between two sets of coordinates. Geodist lat lon lat1 lon1, gen(dist) miles I have then used these latitudes and longitudes to calculate distances between schools and these points of interest using the following command: Every value in lon1 lat1 lon2 lat2 lon3 lat3. which represents points of interest 1, 2, 3. geodist is a useful command in Stata that helps you to find the distance between two cities/locations, the nearest location from your target city/location, and the number of cities/location within a certain radius. I then have variables lon1 lat1 lon2 lat2 lon3 lat3. For each of these schools I have a latitude and longitude (lat and Lon). Use HIGHLIGHT() instead.I have a set of data which is long by schools in one single year (ie each observation is a school in 2019). Note, SNIPPET() doesn't support limiting by fields. For example, with a LIMIT 20,10 clause, SNIPPET() will be called at most 10 times. SNIPPET() is a "post limit" function, meaning that computing snippets is postponed not just until the entire final result set is ready, but even after the LIMIT clause is applied. Where myUdf() would be a UDF that fetches a document by its ID from some external storage. It can also be used to highlight the text fetched from other sources using an UDF: SELECT id, SNIPPET(myUdf(id), 'my.query', 'limit=100') FROM myIndex WHERE MATCH('my.query') SNIPPET() can also highlight non-indexed text: mysql SELECT id, SNIPPET('text to highlight', 'my.query', 'limit=100') FROM myIndex WHERE MATCH('my.query') QUERY() expression in this example returns current fulltext query. ![]() Make sure 'print active sheets' is selected, then print. Then go to 'file' and then 'print' like you normally would. Then hold down control, and click on each additional tab you want to print, excluding the tab, or tabs you don't want to print. The first argument in this case should be field name: SELECT SNIPPET(body, QUERY()) FROM myIndex WHERE MATCH('my.query') Just click on the first tab you want to print and make it active. SNIPPET() can fetch the text to use in highlighting from the table itself. It's possible to pass options to the function as the third, fourth and so on arguments. double geora, geodec, geodist / geocent for moon, not used here. The first two arguments are: the text to highlight, and a query. print an almanac of rise/set and twilight for the sun and moon for the specified. SNIPPET() can be used to highlight search results in a given text. The complete syntax and a few examples are as follows: GEODIST(lat1, lon1, lat2, lon2, ) AS dist, WEIGHT() AS w FROM test WHERE MATCH ('test') ORDER BY w DESC, dist ASC If one or both the members are missing, the command returns NULL. Given a sorted set representing a geospatial index, populated using the GEOADD command, the command returns the distance between the two specified members in the specified unit. ![]() GEODIST() also takes an optional 5th argument that lets you easily convert between input and output units, and pick the specific geodistance formula to use. Return the distance between two members in the geospatial index represented by the sorted set. An optimized path will be selected when one pair of the arguments refers directly to a pair attributes and the other one is constant. You can use arbitrary expression as any of the four coordinates. Note that by default both latitudes and longitudes must be in radians and the result will be in meters. GEODIST(lat1, lon1, lat2, lon2, \) function computes geosphere distance between two given points specified by their coordinates. ![]()
